Direct Known Subclasses:

ViewFileItem

public class FileItem
extends CanvasItem

Binary data interface for use in DynamicForms. Allows users to select a single file for upload. In read-only mode (canEdit:false), can display the contents of "imageFile" fields.

Editable mode

The editForm will be automatically generated and displayed as this.canvas, allowing the user to select file(s) to upload.

See the Upload Overview for information on using this control.

Read-only mode

For fields of type "blob" the raw data value will be displayed in the generated displayForm.

For other fields, the displayCanvas will be displayed.

For "imageFile" fields with showFileInline set to true, the image-file will be streamed and displayed inline within the displayCanvas.

Otherwise, the displayCanvas will render out View and Download icons and the fileName.

setMultiple

public void setMultiple(java.lang.Boolean multiple)

When true, allow the file-selection dialog shelled by the browser to select multiple files.

Support is not full-cycle at the server - that is, there are server APIs for retrieving each file that was uploaded, but no built-in support for storing multiple files against a single DataSource field. However, you can write custom server DMI code to do something with the files - for instance, you could create multiple new DataSource records for each file via a server DMI like this below:

     String fileNameStr = (String)dsRequest.getValues().get("image_filename").toString();
 
     String[] fileNames = fileNameStr.split(", ");
     List files = dsRequest.getUploadedFiles();
 
     for (int i = 0; i < files.size(); i++) {
         ISCFileItem file = (ISCFileItem)files.get(i);
         InputStream fileData = file.getInputStream();
         DSRequest inner = new DSRequest("mediaLibrary", "add");
         Map values = new HashMap();
         values.put("title", dsRequest.getValues().get("title"));
         values.put("image", fileData);
         values.put("image_filename", fileNames[i]);
         values.put("image_filesize", file.getSize());
         values.put("image_date_created", new Date());
         
         inner.setValues(values);
         inner.execute();
     }
     
     DSResponse dsResponse = new DSResponse();
     
     dsResponse.setStatus(0);
 
     return dsResponse;
  

Overrides:

setMultiple in class CanvasItem

Parameters:

multiple - Default value is true

getMultiple

public java.lang.Boolean getMultiple()

When true, allow the file-selection dialog shelled by the browser to select multiple files.

     }
     
     DSResponse dsResponse = new DSResponse();

Overrides:

Returns:

Boolean

setShouldSaveValue

public void setShouldSaveValue(java.lang.Boolean shouldSaveValue)

Should this item's value be saved in the form's values and hence returned from form.getValues()?

shouldSaveValue:false is used to mark formItems which do not correspond to the underlying data model and should not save a value into the form's values. Example includes visual separators, password re-type fields, or checkboxes used to show/hide other form items.

A shouldSaveValue:false item should be given a value either via defaultValue or by calling form.setValue(item, value) or formItem.setValue(value). Providing a value via form.values or form.setValues() will automatically switch the item to shouldSaveValue:true.

Note that

• if an item is shouldSaveValue true, but has no name, a warning is logged, and shouldSaveValue will be set to false.

Overrides:

setShouldSaveValue in class CanvasItem

Parameters:

shouldSaveValue - Default value is true

getShouldSaveValue

public java.lang.Boolean getShouldSaveValue()

Should this item's value be saved in the form's values and hence returned from form.getValues()?

shouldSaveValue:false is used to mark formItems which do not correspond to the underlying data model and should not save a value into the form's values. Example includes visual separators, password re-type fields, or checkboxes used to show/hide other form items.

A shouldSaveValue:false item should be given a value either via defaultValue or by calling form.setValue(item, value) or formItem.setValue(value). Providing a value via form.values or form.setValues() will automatically switch the item to shouldSaveValue:true.

Note that

• if an item is shouldSaveValue true, but has no name, a warning is logged, and shouldSaveValue will be set to false.

Overrides:

getShouldSaveValue in class CanvasItem

Returns:

Boolean

setShowFileInline

public void setShowFileInline(java.lang.Boolean showFileInline)

Indicates whether to stream the image and display it inline or to display the View and Download icons.

Parameters:

showFileInline - Default value is null

getShowFileInline

public java.lang.Boolean getShowFileInline()

Indicates whether to stream the image and display it inline or to display the View and Download icons.

Returns:

Boolean

getUploadItem

public UploadItem getUploadItem()

The UploadItem created automatically and displayed in the editForm when canEdit is true.

This component is an com.smartgwt.client.types.AutoChild and as such may be customized via fileItem.uploadItemDefaults and fileItem.uploadItemProperties.

Returns:

UploadItem

setDefaultProperties

public static void setDefaultProperties(FileItem fileItemProperties)

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 of the class instance passed to this function. 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:

fileItemProperties - properties that should be used as new defaults when instances of this class are created
