public class DrawItem
extends BaseClass
implements HasClickHandlers, HasMouseDownHandlers, HasMouseMoveHandlers, HasMouseOutHandlers, HasMouseOverHandlers, HasMouseUpHandlers, HasMovedHandlers, HasDragMoveHandlers, HasDragResizeMoveHandlers, HasDragResizeStartHandlers, HasDragResizeStopHandlers, HasDragStartHandlers, HasDragStopHandlers, HasResizedHandlers, HasShowContextMenuHandlers
```
Base class for graphical elements drawn in a DrawPane. All properties and methods documented here are available on all DrawItems unless otherwise specified.
Each DrawItem has its own local transform that maps its local coordinate system to the drawing coordinate system that is shared by all DrawItems in the same DrawPane (explained here). The local transform is a combination of rotation, scaling, and other affine transformations. The DrawItem is first translated, then scaled, then sheared in the direction of the x-axis, then sheared in the directiton of the y-axis, and then finally rotated.
Note that DrawItems as such should never be created, only concrete subclasses such as DrawGroup and DrawLine.
See DrawPane for the different approaches to create DrawItems.

```
public DrawRect getResizeOutline()
                          throws java.lang.IllegalStateException

  - setResizeViaLocalTransformOnly
```
public void setResizeViaLocalTransformOnly(boolean resizeViaLocalTransformOnly)
                                    throws java.lang.IllegalStateException
```
    If this DrawItem is showing KnobType.RESIZE control knobs, should resizing the shape solely update the local transform (for example, the DrawItem's scale or translation)?.
    The default is false, which means that the DrawItem is allowed to modify its shape properties in order to fit within a given width and height. Some examples:
    - A DrawOval might decrease its radius when resized to a smaller size.
    - A DrawPath might change its points to lengthen all line segments in the path by some proportion so that it fits into a larger size.
    This approach allows a DrawItem to maintain the same line width even as it is being resized.
    If this property is set to true then all visual aspects of the DrawItem, including the line width and the fill, will be magnified or reduced during resizes as if the DrawItem were placed under a lens.
    Parameters:
    
    resizeViaLocalTransformOnly - Default value is false
    
    Throws:
    
    java.lang.IllegalStateException - this property cannot be changed after the underlying component has been created
  - getResizeViaLocalTransformOnly
```
public boolean getResizeViaLocalTransformOnly()
```
    If this DrawItem is showing KnobType.RESIZE control knobs, should resizing the shape solely update the local transform (for example, the DrawItem's scale or translation)?.
    The default is false, which means that the DrawItem is allowed to modify its shape properties in order to fit within a given width and height. Some examples:
    - A DrawOval might decrease its radius when resized to a smaller size.
    - A DrawPath might change its points to lengthen all line segments in the path by some proportion so that it fits into a larger size.
    This approach allows a DrawItem to maintain the same line width even as it is being resized.
    If this property is set to true then all visual aspects of the DrawItem, including the line width and the fill, will be magnified or reduced during resizes as if the DrawItem were placed under a lens.

  - addShowContextMenuHandler
```
public com.google.gwt.event.shared.HandlerRegistration addShowContextMenuHandler(ShowContextMenuHandler handler)
```
    Add a showContextMenu handler.
    Executed when the right mouse button is clicked. The default implementation of this method auto-creates a Menu from the Canvas.contextMenu property on this component and then calls Menu.showContextMenu() on it to show it.
    If you want to show a standard context menu, you can simply define your Menu and set it as the contextMenu property on your component - you do not need to override this method.
    If you want to do some other processing before showing a menu or do something else entirely, then you should override this method. Note that the return value from this method controls whether or not the native browser context menu is shown.
    
    Specified by:
    
    addShowContextMenuHandler in interface HasShowContextMenuHandlers
    
    Parameters:
    
    handler - the showContextMenu handler
    
    Returns:
    
    HandlerRegistration used to remove this handler

  - showKnobs
```
public void showKnobs(KnobType... knobType)
```
    Shows a set of control knobs for this drawItem. Updates knobs to include the specified knobType, and if necessary draws out the appropriate control knobs.
    
    Parameters:
    
    knobType - knobs to show

    Returns:
    
    whether setStartArrow() is supported by this DrawItem.
  - setDefaultProperties
```
public static void setDefaultProperties(DrawItem drawItemProperties)
```
    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:
    
    drawItemProperties - properties that should be used as new defaults when instances of this class are created
