public class ColumnTree
extends Layout
implements HasNodeSelectedHandlers, DataBoundComponent
```
The Smart GWT system supports hierarchical data (also referred to as tree data due to its "branching" organization) with:
- the Tree class, which manipulates hierarchical data sets
- the TreeGrid widget class, which extends the ListGrid class to visually present tree data in an expandable/collapsible format.
- the ColumnTree widget class, which visually presents tree data in a so-called "Miller Column" format.
For information on DataBinding Trees, see TreeDataBinding.
A ColumnTree shows a single branch of the underlying Tree horizontally, from left to right. Thus, the leftmost column shows all the top-level nodes. When the user clicks one of those nodes, a new column is shown immediately to the right of the top-level column, showing the selected node's children. Additional columns are shown as required to present lower-level children. The behavior of ColumnTree is similar to that of the Browser interface in the Apple™ iTunes™ application.

  - getBackButton
```
public IButton getBackButton()
                      throws java.lang.IllegalStateException
```
    When using single-column mode, this is the "Back" button that you see hovering above the column UI and that allows backward navigation.
    This component is an AutoChild named "backButton". For an overview of how to use and configure AutoChildren, see Using AutoChildren.
    
    Returns:
    
    Current backButton value. Default value is null
    
    Throws:
    
    java.lang.IllegalStateException - if this widget has not yet been rendered.
  - setBackButtonTitle
```
public ColumnTree setBackButtonTitle(java.lang.String backButtonTitle)
```
    When using single-column mode, this i18n property dictates the title for the button docked to the top left which allows navigation back through the column tree.
    
    Parameters:
    
    backButtonTitle - New backButtonTitle value. Default value is "Back"
    
    Returns:
    
    ColumnTree instance, for chaining setter calls
  - getBackButtonTitle
```
public java.lang.String getBackButtonTitle()
```
    When using single-column mode, this i18n property dictates the title for the button docked to the top left which allows navigation back through the column tree.
    
    Returns:
    
    Current backButtonTitle value. Default value is "Back"
  - setCanDragRecordsOut
```
public ColumnTree setCanDragRecordsOut(java.lang.Boolean canDragRecordsOut)
```
    Indicates whether records can be dragged from this listGrid and dropped elsewhere.
    NOTE: If canDragRecordsOut is initially enabled or might be dynamically enabled after the grid is created, it may be desirable to disable touch scrolling so that touch-dragging a record starts a drag operation rather than a scroll, but see the discussion of drag handles. If Canvas.disableTouchScrollingForDrag is set to true, then touch scrolling will be disabled automatically. However, for accessibility reasons, it is recommended to leave touch scrolling enabled and provide an alternative set of controls that can be used to perform drag and drop of records out of the grid.
    
    Parameters:
    
    canDragRecordsOut - New canDragRecordsOut value. Default value is false
    
    Returns:
    
    ColumnTree instance, for chaining setter calls

```
public void folderDrop(TreeNode[] nodes,
                       TreeNode folder,
                       int index,
                       Canvas sourceWidget)
```
    Process a drop of one or more nodes on a TreeGrid folder.
    Note: See TreeGridDrop for an overview of TreeGrid drag and drop behavior. Add logic in your drop handler to perform custom drop behaviors; to suppress the built-in behavior described below, use event.cancel()
    The default behavior is to simply delegate to the transferNodes() method; thus, the correct way to perform a programmatic folder drop, with all the built-in behaviors described below, is to call transferNodes()
    If this is a self-drop, nodes are simply reordered. An "update" operation will be submitted to update the parentId field of the moved node(s).
    For a drop from another widget, TreeGrid.transferDragData() is called which, depending on the dragDataAction specified on the source widget, may either remove the source nodes from the original list (dragDataAction:"move") or just provide a copy to this tree (dragDataAction:"copy").
    In either case the new row(s) appear in the folder at the index specified by the arguments of the same name.
    If this grid is databound, the new nodes will be added to the dataset by calling DataSource.addData(). Further, if the new nodes were dragged from another databound component, and addDropValues is true, getDropValues will be called for every item being dropped.
    As a special case, if the sourceWidget is also databound and a foreignKey relationship is declared from the sourceWidget's DataSource to this TreeGrid's DataSource, the interaction will be treated as a "drag recategorization" use case such as files being placed in folders, employees being assigned to teams, etc. "update" DSRequests will be submitted that change the foreignKey field in the dropped records to point to the tree folder that was the target of the drop. In this case no change will be made to the Tree data as such, only to the dropped records.
    For multi-record drops, Queuing is automatically used to combine all DSRequests into a single HTTP Request (see QuickStart Guide, Server Framework chapter). This allows the server to persist all changes caused by the drop in a single transaction (and this is automatically done when using the built-in server DataSources with Power Edition and above).
    If these default persistence behaviors are undesirable, use event.cancel(), then implement your own behavior, typically by using grid.updateData() or addData() to add new records.
    NOTE: the records you receive in this event are the actual Records from the source component. Use DataSource.copyRecords() to create a copy before modifying the records or using them with updateData() or addData().
    
    Parameters:
    
    nodes - List of nodes being dropped
    
    folder - The folder being dropped on
    
    index - Within the folder being dropped on, the index at which the drop is occurring. Only passed if canReorderRecords is true.
    
    sourceWidget - The component that is the source of the nodes (where the nodes were dragged from)

    Returns the title to show for the header of indicated column. Only called if shouldShowHeader() returns true for this column.
    By default, returns firstColumnTitle for the first column, and for subsequent columns, the result of this.data.getTitle() called on the node passed to this function.
    
    Parameters:
    
    node - parent node for the nodes to be shown in the column
    
    colNum - index of the column
  - getRecord
```
public TreeNode getRecord(int index)
```
    Retrieve a record by index.
    If colNum is passed, returns the record found in that column at that index, or null if the column doesn't exist or the index is too high.
    With no colNum parameter, a record's index is it's position counting from the first record of the first column and including all records in each column. Note that both index and colNum are zero-based - so the first column is column 0, not column 1.
    
    Parameters:
    
    index - index of record to return.
    
    Returns:
    
    node at the specified index
  - getRecord
```
public TreeNode getRecord(int index,
                          java.lang.Integer colNum)
```
    Retrieve a record by index.
    If colNum is passed, returns the record found in that column at that index, or null if the column doesn't exist or the index is too high.
    With no colNum parameter, a record's index is it's position counting from the first record of the first column and including all records in each column. Note that both index and colNum are zero-based - so the first column is column 0, not column 1.
    
    Parameters:
    
    index - index of record to return.
    
    colNum - optional index of the column
    
    Returns:
    
    node at the specified index
  - getSelectedRecord
```
public Record getSelectedRecord()
```
    Get the selected record, that is, the parent of the nodes in the rightmost visible column.
    This is generally the most recently clicked node unless programmatic navigation has taken place.
    If only the first column is showing, the root node is returned (which can be detected via Tree.isRoot()).
    
    Returns:
    
    the selected record
  - navigateBack
```
public void navigateBack()
```
    Navigate to the previous column.
  - shouldShowHeader

public void shouldShowHeader(TreeNode node,
                             int colNum)
```
    Whether the indicated column should show a header. Returns this.showHeaders by default, override for different behavior.
    
    Parameters:
    
    node - parent node for the nodes to be shown in the column
    
    colNum - index of the column
  - transferNodes
```
public void transferNodes(TreeNode[] nodes,
                          TreeNode folder,
                          java.lang.Integer index,
                          Canvas sourceWidget)
```
    Transfer a list of TreeNodes within this treeGrid or from from some other component (does not have to be a databound component) into this component. This method is only applicable to list-type components, such as listGrid, treeGrid or tileGrid. Please see the paragraph below for special rules concerning multi-link trees.
    This method implements the automatic drag-copy and drag-move behavior and calling it is equivalent to completing a drag and drop of the nodes (the default folderDrop() implementation simply calls transferNodes())
    Note that this method is asynchronous - it may need to perform server turnarounds to prevent duplicates in the target component's data. If you wish to be notified when the transfer process has completed, you can either pass the optional callback to this method or implement the DataBoundComponent.dropComplete() method on this component.
    For a TreeGrid, see also transferSelectedData().
    Multi-link trees
    If both the target treeGrid and the sourceWidget for this transfer are multi-link treeGrids, the nodes parameter must be an array of NodeLocators rather than TreeNodes. Likewise, if the target (this) component is a multi-link treeGrid, the folder parameter must be a NodeLocator.
    You can obtain a NodeLocator for a visible node occurence in a multi-link TreeGrid by calling its data model's getNodeLocator() method.
    
    Parameters:
    
    nodes - Nodes to transfer to this component
    
    folder - The target folder (eg, of a drop interaction), for context
    
    index - Insert point within the target folder data for the transferred nodes
    
    sourceWidget - The databound or non-databound component from which the nodes are to be transferred.

  - setDefaultProperties
```
public static void setDefaultProperties(ColumnTree columnTreeProperties)
```
    Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties set on the SmartGWT class instance passed to this function before its underlying SmartClient JS object was created. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.
    Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.
    
    Parameters:
    
    columnTreeProperties - properties that should be used as new defaults when instances of this class are created

    Bind to a DataSource.
    Binding to a DataSource means that the component will use the DataSource to provide default data for its fields.
    When binding to a new DataSource, if the component has any existing "fields" or has a dataset, these will be discarded by default, since it is assumed the new DataSource may represent a completely unrelated set of objects. If the old "fields" are still relevant, pass them to setDataSource().

    For databound ColumnTrees, this attribute can be used to customize the ResultTree object created for this ColumnTree when data is fetched.
    
    Parameters:
    
    resultTreeProperties - the data properties
  - setDataPageSize
```
public ColumnTree setDataPageSize(int dataPageSize)
```
    Description copied from interface: DataBoundComponent
    
    When using data paging, how many records to fetch at a time. If set to a positive integer, dataPageSize will override the default resultSize for ResultSets automatically created when you call fetchData() (and similarly for the resultSize of ResultTrees). The default of 0 means to just use the default page size of the data container.
    Note that regardless of the dataPageSize setting, a component will always fetch all of data that it needs to draw. Settings such as showAllRecords:true, drawAllMaxCells and drawAheadRatio can cause more rows than the configured dataPageSize to be fetched.
    
    Specified by:

```
    Description copied from interface: DataBoundComponent
    
    Whether to show fields of non-atomic types when a DataBoundComponent is given a DataSource but no component.fields.
    If true, the component will show fields that declare a complex type, for example, a field 'shippingAddress' that declares type 'Address', where 'Address' is the ID of a DataSource that declares the fields of a shipping address (city, street name, etc).
    Such fields may need custom formatters or editors in order to create a usable interface, for example, an Address field in a ListGrid might use a custom formatter to combine the relevant fields of an address into one column, and might use a pop-up dialog for editing.

```
    Description copied from interface: DataBoundComponent
    
    If set, detect and prevent duplicate records from being transferred to this component, either via drag and drop or via DataBoundComponent.transferSelectedData(com.smartgwt.client.widgets.DataBoundComponent). When a duplicate transfer is detected, a dialog will appear showing the duplicateDragMessage.
    If the component either does not have a DataSource or has a DataSource with no primaryKey declared, duplicate checking is off by default. If duplicate checking is enabled, it looks for an existing record in the dataset that has all of the properties of the dragged record, and considers that a duplicate.
    For DragDataAction:"copy" where the target DataSource is related to the source DataSource by foreignKey, a duplicate means that the target list, as filtered by the current criteria, already has a record whose value for the foreignKey field matches the primaryKey of the record being transferred.
    For example, consider dragging "employees" to "teams", where "teams" has a field "teams.employeeId" which is a foreignKey pointing to "employees.id", and the target grid has search criteria causing it to show all the members of one team. A duplicate - adding an employee to the same team twice - is when the target grid's dataset contains an record with "employeeId" matching the "id" field of the dropped employee.

    Description copied from interface: DataBoundComponent
    
    Indicates whether to add "drop values" to items dropped on this component, if both the source and target widgets are databound, either to the same DataSource or to different DataSources that are related via a foreign key. "Drop values" are properties of the dropped item that you wish to change (and persist) as a result of the item being dropped on this grid.
    If this value is true and this component is databound, DataBoundComponent.getDropValues() will be called for every databound item dropped on this grid, and an update performed on the item
    
    Specified by:

    When an item is dropped on this component, and addDropValues is true and both the source and target widgets are databound, either to the same DataSource or to different DataSources that are related via a foreign key, this object provides the "drop values" that Smart GWT will apply to the dropped object before updating it.
    If this property is not defined, Smart GWT defaults to returning the selection criteria currently in place for this component. Thus, any databound items (for example, rows from other grids bound to the same DataSource) dropped on the grid will, by default, be subjected to an update that makes them conform to the grid's current filter criteria.
    Note : This is an advanced setting
    
    Specified by:
    
    setDropValues in interface DataBoundComponent

    getDropValues in interface DataBoundComponent
    
    Returns:
    Returns the "drop values" to apply to a record dropped on this component prior to update. Only applicable to databound components - see dropValues for more details. If multiple records are being dropped, this method is called for each of them in turn.
    This method returns the following:
    
    Nothing, if addDropValues is false
    
    dropValues, if that property is set. If the component's criteria object is applicable (as explained in the next item), it is merged into dropValues, with properties in dropValues taking precedence.
    
    The component's criteria object, if the most recent textMatchStyle for the component was "exact" and it is simple criteria (ie, not an AdvancedCriteria object)
    
    Otherwise nothing
    
    You can override this method if you need more complex setting of drop values than can be provided by simply supplying a dropValues object.
  - setProgressiveLoading

```
public ColumnTree setUseFlatFields(java.lang.Boolean useFlatFields)
                            throws java.lang.IllegalStateException
```
    Description copied from interface: DataBoundComponent
    The useFlatFields flag causes all simple type fields anywhere in a nested set of DataSources to be exposed as a flat list for form binding.
    useFlatFields is typically used with imported metadata, such as XMLTools.loadXMLSchema(java.lang.String, com.smartgwt.client.data.XSDLoadCallback) from a XMLTools.loadWSDL(java.lang.String, com.smartgwt.client.data.WSDLLoadCallback), as a means of eliminating levels of XML nesting that aren't meaningful in a user interface, without the cumbersome and fragile process of mapping form fields to XML structures.
    For example, having called WebService.getInputDS(java.lang.String) to retrieve the input message schema for a web service operation whose input message looks like this:
```
 <FindServices>
     <searchFor>search text</searchFor>
     <Options>
         <caseSensitive>false</caseSensitive>
     </Options>
     <IncludeInSearch>
         <serviceName>true</serviceName>
         <documentation>true</documentation>
         <keywords>true</keywords>
     </IncludeInSearch>
 </FindServices>
 
```
    Setting useFlatFields on a DynamicForm that is bound to this input message schema would result in 5 FormItem reflecting the 5 simple type fields in the message.
    For this form, the result of DynamicForm.getValues() might look like:
```
{
    searchFor: "search text",
    caseSensitive: false,
    serviceName: true,
    documentation : true,
    keywords : true
 }
```
    When contacting a WebService, these values can be automatically mapped to the structure of the input message for a web service operation by setting useFlatFields (for use with WebService.callOperation(java.lang.String, java.util.Map, java.lang.String, com.smartgwt.client.data.WebServiceCallback)) or by setting useFlatFields (for use with a DataSource that is 'bound to a WSDL web service' via wsOperation).
    Using these two facilities in conjunction (component.useFlatFields and request.useFlatFields) allows gratuitous nesting to be consistently bypassed in both the user presentation and when providing the data for XML messages.
    You can also set useFlatFields to automatically enable "flattened" XML serialization (request.useFlatFields) for all DataSource requests of a particular operationType.
    Note that useFlatFields is not generally recommended for use with structures where multiple simple type fields exist with the same name, however if used with such a structure, the first field to use a given name wins. "first" means the first field encountered in a depth first search. "wins" means only the first field will be present as a field when data binding.

public ColumnTree setSavedSearchId(java.lang.String savedSearchId)
```
    Description copied from interface: DataBoundComponent
    
    Optional identifier for saved searches that should be applied to this component.
    By default SavedSearches are associated with a component via its local ID and DataSource ID. This property allows developers to override this behavior and explicitly associate a component with a set of saved searches. This can provide a couple of benefits:
    Firstly this ensures that saved searches will be unambiguously associated with the particular component even if the page changes such that a stored minimal locator would no longer applied to the component, without requiring an explicit Canvas.ID.
    Secondly this allows the same set of saved searches to be applied to more than one component on a page. This may be valueable for cases where the same information from the same dataSource is presented to users in multiple places.
    Note: This is an advanced setting.
    
    Specified by:
    
    setSavedSearchId in interface DataBoundComponent
    
    Parameters:

  - getDragData
```
public Record[] getDragData()
```
    Description copied from interface: DataBoundComponent
    
    During a drag-and-drop interaction, this method returns the set of records being dragged out of the component. In the default implementation, this is the list of currently selected records.
    This method is consulted by ListGrid.willAcceptDrop().
    
    Specified by:
    
    getDragData in interface DataBoundComponent
    
    Returns:
    
    Array of Records that are currently selected.
  - transferSelectedData
```
public void transferSelectedData(DataBoundComponent source)
```
    Description copied from interface: DataBoundComponent
    
    Simulates a drag / drop type transfer of the selected records in some other component to this component, without requiring any user interaction. This method acts on the dropped records exactly as if they had been dropped in an actual drag / drop interaction, including any special databound behavior invoked by calling DataBoundComponent.getDropValues() for each dropped record.
    To transfer all data in, for example, a ListGrid, call grid.selection.selectAll() first.
    Note that drag/drop type transfers of records between components are asynchronous operations: Smart GWT may need to perform server turnarounds to establish whether dropped records already exist in the target component. Therefore, it is possible to issue a call to transferSelectedData() and/or the drop() method of a databound component whilst a transfer is still active. When this happens, Smart GWT adds the second and subsequent transfer requests to a queue and runs them one after the other. If you want to be notified when a transfer process has actually completed, use addDropCompleteHandler. See the Dragging documentation for an overview of list grid drag/drop data transfer.
    
    Specified by:
    
    transferSelectedData in interface DataBoundComponent
    
    Parameters:
    
    source - source component from which the records will be tranferred

```
    Description copied from interface: DataBoundComponent
    
    Method to return the fieldName which represents the "title" for records in this Component.

  - fetchData
```
public void fetchData()
```
    Description copied from interface: DataBoundComponent
    
    Retrieves data from the DataSource that matches the specified criteria.
    When fetchData() is first called, if data has not already been provided via setData(), this method will create a ResultSet, which will be configured based on component settings such as fetchOperation and dataPageSize, as well as the general purpose dataProperties. The created ResultSet will automatically send a DSRequest to retrieve data from the dataSource, and from then on will automatically manage paging through large datasets, as well as performing filtering and sorting operations inside the browser when possible - see the ResultSet docs for details.
    NOTE: do not use both autoFetchData and a call to fetchData() - this may result in two DSRequests to fetch data. Use either autoFetchData and setAutoFetchCriteria() or a manual call to fetchData() passing criteria.
    Whether a ResultSet was automatically created or provided via setData(), subsequent calls to fetchData() will simply call resultSet.setCriteria().
    Changes to criteria may or may not result in a DSRequest to the server due to client-side filtering. You can call willFetchData(criteria) to determine if new criteria will result in a server fetch.
    If you need to force data to be re-fetched, you can call invalidateCache() and new data will automatically be fetched from the server using the current criteria and sort direction. NOTE: when using invalidateCache() there is no need to also call fetchData() and in fact this could produce unexpected results.
    This method takes an optional callback parameter (set to a DSCallback) to fire when the fetch completes. Note that this callback will not fire if no server fetch is performed. In this case the data is updated synchronously, so as soon as this method completes you can interact with the new data. If necessary, you can use resultSet.willFetchData() to determine whether or not a server fetch will occur when fetchData() is called with new criteria.
    In addition to the callback parameter for this method, developers can use resultSet.addDataArrivedHandler to be notified every time data is loaded.

  - invalidateCache
```
public void invalidateCache()
```
    Description copied from interface: DataBoundComponent
    
    Invalidate the current data cache for this databound component via a call to the dataset's invalidateCache() method, for example, ResultSet.invalidateCache().
    NOTE: there is no need to call invalidateCache() when a save operation is performed on a DataSource. Automatic cache synchronization features will automatically update caches - see ResultSet for details. If automatic cache synchronization isn't working, troubleshoot the problem using the steps suggested in the FAQ rather than just calling invalidateCache(). Calling invalidateCache() unnecessarily causes extra server load and added code complexity.
    Calling invalidateCache() will automatically cause a new fetch to be performed with the current set of criteria if data had been previously fetched and the component is currently drawn with data visible - there is no need to manually call fetchData() after invalidateCache() and this could result in duplicate fetches.
    While data is being re-loaded after a call to invalidateCache(), the widget is in a state similar to initial data load - it doesn't know the total length of the dataset and any APIs that act on records or row indices will necessarily fail and should not be called. To detect that the widget is in this state, call ResultSet.lengthIsKnown().
    invalidateCache() only has an effect if this component's dataset is a data manager class that manages a cache (eg ResultSet or ResultTree). If data was provided as a simple Array or List, invalidateCache() does nothing.

  - getRecordList
```
public RecordList getRecordList()
```
    Description copied from interface: DataBoundComponent
    Return the underlying data of this DataBoundComponent as a RecordList.
    Depending on the component configuration, the actual JavaScript instance of the returned RecordList may be one of several types:
    - If the component is not bound to a DataSource, the instance is generally an Array of Record.
    - If the component is bound to a DataSource, the instance is a ResultSet.
    - If the component is a grouped ListGrid, the instance is a Tree. To access the ungrouped record list regardless of grouping status, use
      isGrouped() ? getOriginalRecordList() : getRecordList()
    - If the component is a TreeGrid, the instance is a ResultTree.
    The underlying type determines the structure of the returned data. An Array or ResultSet represents a list of records, but a Tree or ResultTree represents a list of open rows in the tree, including groups or other nodes which contain no records.

    Description copied from interface: DataBoundComponent
    
    Uses a "fetch" operation on the current DataSource to retrieve data that matches the current filter and sort criteria for this component, then exports the resulting data to a file or window in the requested format.
    A variety of DSRequest settings, such as exportAs and exportFilename, affect the exporting process: see exportResults for further detail.
    Note that data exported via this method does not include any client-side formatting and relies on both the Smart GWT server and server-side DataSources. To export client-data with formatters applied, see exportClientData, which still requires the Smart GWT server but does not rely on server-side DataSources.
    For more information on exporting data, see DataSource.exportData.
    
    Specified by:

    Parameters:
    
    requestProperties - additional properties to set on DSRequest that will be issued
    
    callback - Optional callback. Note that this parameter only applies if you specify exportToClient: false in the request properties, because file downloads don't provide ordinary framework callbacks

    Description copied from interface: DataBoundComponent
    
    Before we start editing values in this DataBoundComponent, should we perform a deep clone of the underlying values. See DataSource.getDeepCloneOnEdit() for details of what this means.
    If this value is not explicitly set, it defaults to the DataSource deepCloneOnEdit value. This value can also be overridden per-field with DataSourceField.setDeepCloneOnEdit(java.lang.Boolean).
    Like the other deepCloneOnEdit settings, this flag only has an effect if you are editing a values object that contains nested objects or arrays, using Canvas.setDataPath(java.lang.String)

    DataBoundComponent instance, for chaining setter calls
  - setFields
```
public ColumnTree setFields(com.google.gwt.core.client.JavaScriptObject... fields)
```
    Description copied from interface: DataBoundComponent
    
    Field setter variant (alternative to setFields(FormItem...), setFields(ListGridField...), etc.) that will accept an array of JavaScriptObject, rather than an array of SmartGWT Java wrappers of the field class type (e.g. FormItem, ListGridField, etc.) This is an advanced method and only for cases where you have the JavaScriptObject for each field but want to avoid having to create each associated SmartGWT Java wrapper.
    Note: use toArray() to create a Java array of JavaScriptObject if you only have the array itself as a single JavaScriptObject.
    
    Specified by:
    
    setFields in interface DataBoundComponent
    
    Parameters:
    
    fields - the component fields
    
    Returns:
    
    DataBoundComponent instance, for chaining setter calls
  - getFieldsAsJavaScriptObjects
```
public com.google.gwt.core.client.JavaScriptObject[] getFieldsAsJavaScriptObjects()
```
    Description copied from interface: DataBoundComponent
    
    Return the fields as JavaScriptObjects rather than as SmartGWT Java wrappers of the field class type (e.g. FormItem, ListGridField, etc.) This avoids building the SmartGWT Java wrappers for the fields in situations where they aren't needed - and for FormItems in particular - where there may not be enough information to determine the correct subclass, such as before the SmartClient instance underlying the DynamicForm has been created.
    
    Specified by:
    
    getFieldsAsJavaScriptObjects in interface DataBoundComponent
    
    Returns:
    
    the component fields
  - getFieldCount
```
public int getFieldCount()
```
    Description copied from interface: DataBoundComponent
    
    Return the number of fields.
    
    Specified by:
    
    getFieldCount in interface DataBoundComponent
    
    Returns:
    
    the number of fields
  - transferRecords
```
public void transferRecords(Record[] records,
                            Record targetRecord,
                            java.lang.Integer index,
                            Canvas sourceWidget,
                            TransferRecordsCallback callback)
```
    Description copied from interface: DataBoundComponent
    
    Transfer a list of Records from another component (does not have to be a databound component) into this component. This method is only applicable to list-type components, such as ListGrid or com.smartgwt.client.widgets.tile.TileGridTileGrid. Notably, it does not apply to TreeGrid; the equivalent for treeGrids is transferNodes.
    This method implements the automatic drag-copy and drag-move behaviors of components like ListGrid, and calling it is equivalent to completing a drag and drop of the dropRecords (the default record drop behavior is simply to call transferRecords(), passing in the dropped nodes)
    Note that this method is asynchronous - it may need to perform server turnarounds to prevent duplicates in the target component's data. If you wish to be notified when the transfer process has completed, you can either pass a non-null callback to this method or add a DropCompleteHandler to this component.
    See also transferSelectedData()
    
    Specified by:
    
    transferRecords in interface DataBoundComponent
    
    Parameters:
    
    records - Recordss to transfer to this component
    
    targetRecord - The target record (eg, of a drop interaction), for context
    
    index - Insert point relative to the target record for the transferred records
    
    sourceWidget - The databound or non-databound component from which the records are to be transferred.
    
    callback - optional TransferRecordsCallback to be fired when the transfer process has completed (pass null if your code does not need to be called back). The callback will be passed the list of records actually transferred to this component
  - setDragDataCustomizer
```
public ColumnTree setDragDataCustomizer(DragDataCustomizer customizer)
```
    During a drag-and-drop interaction, this method returns the set of records being dragged out of the component. In the default implementation, this is the list of currently selected records.
    This method is consulted by willAcceptDrop().
    
    Parameters:
    
    DragDataCustomizer - customizer
    
    Returns:
    
    DataBoundComponent instance, for chaining setter calls
  - getSort
```
public SortSpecifier[] getSort()
```
    Description copied from interface: DataBoundComponent
    
    Returns the current SortSpecifiers for this component. Will return null if this component has never been sorted, or the underlying SmartClient widget does not exist.
    
    Specified by:
    
    getSort in interface DataBoundComponent
    
    Returns:
    
    current sort specifiers for this component (null if unsorted or no SC widget)
  - setSort
```
public ColumnTree setSort(SortSpecifier... sortSpecifiers)
```
    Description copied from interface: DataBoundComponent
    
    Sort the component on one or more fields.
    Pass in an array of SortSpecifiers to have the component's data sorted by the fields in each specifier.property and in the directions specified. The component can be sorted by any combination of fields, including fields specified in the fields array and unused fields from the underlying dataSource, if there is one.
    If setSort() is called on a component which doesn't yet have a SmartClient widget, the widget will be created. If autoFetchData is set and a DataSource has been set, this will result in data being fetched.
    
    Specified by:
    
    setSort in interface DataBoundComponent
    
    Parameters:
    
    sortSpecifiers - Array of SortSpecifier objects
  - setLogicalStructure
```
public com.smartgwt.logicalstructure.core.LogicalStructureObject setLogicalStructure(com.smartgwt.logicalstructure.widgets.grid.ColumnTreeLogicalStructure s)
```
    Setter implementing the LogicalStructure interface, which supports Eclipse's logical structure debugging facility.
  - getLogicalStructure
```
public com.smartgwt.logicalstructure.core.LogicalStructureObject getLogicalStructure()
```
    Getter implementing the LogicalStructure interface, which supports Eclipse's logical structure debugging facility.
    
    Specified by:
    
    getLogicalStructure in interface LogicalStructure
    
    Overrides:
    
    getLogicalStructure in class Layout
