  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.

                                  throws java.lang.IllegalStateException

      Should events inside this DrawItem be attributed to it regardless of which pixels are actually set, if no fill is specified? If set for DrawItems that aren't closed, will capture events occurring in the region that would filled if a fill were specified. This property is true by default for closed shapes, and false for paths, lines, etc.

      For `DrawLabel`, this property defaults to true, meaning clicks anywhere in the label's bounding box are attributed to the label. Since pixel-level text hit detection is not practical, setting `eventOpaque` to false on a DrawLabel causes it to never receive click events, allowing clicks to pass through to items underneath.

      When a non-null `title` is set, this AutoChild is created automatically and positioned at the `center` of this `DrawItem` . The `titleLabel` moves with this `DrawItem` and, depending on `titleRotationMode`, can rotate with this `DrawItem` as well.

      The following `passthrough` applies:
      `title` for `DrawLabel.contents`.

      Related to the `titleLabel` is the `titleLabelBackground` which allows a border to be placed around the `titleLabel` and/or a background added. By default, shapes that are commonly filled such as `DrawTriangle`s, with the exception of `DrawSector`s, do not show the `titleLabelBackground` (see `showTitleLabelBackground`).

      This component is an AutoChild named "titleLabel". For an overview of how to use and configure AutoChildren, see `Using AutoChildren`.

      Returns:

    - #### setUseSimpleTransform

          public DrawItem setUseSimpleTransform(boolean useSimpleTransform)

      If true, when a DrawItem is `moved` or `resized`, the transform is applied by manipulating the shape coordinates, if possible, rather than by introducing scaling, shearing, rotation, or translation. This is only supported currently for `DrawRect`, `DrawOval`, `DrawDiamond`, `DrawImage`, and `DrawLabel`, and only if no shearing is already present. Further, it's only possible to keep the transform simple if both axes are scaled by the same amount during the resize (or end up at the same scale if the DrawItem is already scaled unevenly), unless the rotation angle is a multiple of 90 degrees.

      For `DrawPolygon` and other shapes not based on a box (top/left/width/height), we can't safely just modify coordinates to effect a resize as we can do for `DrawRect` (and similar), so resizing will normally introduce or modify the transform, potentially introducing scaling or shearing, rather than modifying coordinates. For such `DrawItem`s, we avoid trying to manipulate the coordinates, in part, because there's a danger that the floating point error may accumulate over time and warp the shape.

      Note : This is an advanced setting

      Parameters:
        `useSimpleTransform` - New useSimpleTransform value. Default value is true
      Returns:
        `DrawItem` instance, for chaining setter calls

    - #### getXShearFactor

          public double getXShearFactor()

      The slope of an x-shearing transformation applied to this DrawItem. Each point in the shape is moved along the x-axis a distance that is proportional to the initial y-coordinate of the point.
      Returns:
        Current xShearFactor value. Default value is 0.0

    - #### setYShearFactor

          public DrawItem setYShearFactor(double yShearFactor)
                                   throws java.lang.IllegalStateException

      The slope of a y-shearing transformation applied to this DrawItem. Each point in the shape is moved along the y-axis a distance that is proportional to the initial x-coordinate of the point.

      Note : This is an advanced setting

      Parameters:

      Returns:
        Current yShearFactor value. Default value is 0.0

    - #### setZIndex

          public DrawItem setZIndex(java.lang.Integer zIndex)
                             throws java.lang.IllegalStateException

      Relative stacking order of this draw item with respect to other items in the same `DrawPane` or `DrawGroup`.

      null means that the zIndex has not been resolved. Upon adding this draw item to a `DrawPane` or `DrawGroup`, this item's zIndex will be resolved to the next higher auto-assigned zIndex. Note that this may still be less than another item's zIndex if `bringToFront()` was called on that item.

      If two items within the same `DrawPane` or `DrawGroup` have the same zIndex, then they are stacked in the order in which they were added to the `DrawPane` or `DrawGroup`.

      When the `DrawPane`'s `drawingType` is `DrawingType.BITMAP`, zIndex, `bringToFront()`, and `sendToBack()` are not supported for `DrawLabel`s on iOS due to platform limitations.
      If this method is called after the component has been drawn/initialized: Setter for `zIndex`.

      Parameters:
        `zIndex` - new `zIndex`. If null and this draw item is already in a `DrawPane` or `DrawGroup`, then this item's zIndex will be set to the next higher auto-assigned zIndex.

        Note that when setting draw items' zIndexes via this advanced API, the application should take over management of all draw items' zIndexes, and `bringToFront()` / `sendToBack()` should not be used, as those APIs assume automatic management of zIndexes. Default value is null

      Returns:
        `DrawItem` instance, for chaining setter calls
      Throws:
        `java.lang.IllegalStateException` - this property cannot be changed after the component has been created
      See Also:

    - #### getZIndex

          public java.lang.Integer getZIndex()

      Relative stacking order of this draw item with respect to other items in the same `DrawPane` or `DrawGroup`.

      null means that the zIndex has not been resolved. Upon adding this draw item to a `DrawPane` or `DrawGroup`, this item's zIndex will be resolved to the next higher auto-assigned zIndex. Note that this may still be less than another item's zIndex if `bringToFront()` was called on that item.

      If two items within the same `DrawPane` or `DrawGroup` have the same zIndex, then they are stacked in the order in which they were added to the `DrawPane` or `DrawGroup`.

      When the `DrawPane`'s `drawingType` is `DrawingType.BITMAP`, zIndex, `bringToFront()`, and `sendToBack()` are not supported for `DrawLabel`s on iOS due to platform limitations.

      Returns:
        Returns the `zIndex` of this draw item. Default value is null
      See Also:
        `ZIndex overview and related methods`

    - #### bringToFront

          public void bringToFront()

      Places this draw item at the top of the stacking order so that it appears in front of other draw items in the same `DrawPane` or `DrawGroup`.

      When the `DrawPane`'s `drawingType` is `DrawingType.BITMAP`, `zIndex`, bringToFront(), and `sendToBack()` are not supported for `DrawLabel`s on iOS due to platform limitations.

          public com.google.gwt.event.shared.HandlerRegistration addClickHandler(ClickHandler handler)

      Add a click handler.

      Notification fired when the user clicks on this DrawItem.

      Note that if this item is part of a `DrawGroup`, then the group's `useGroupRect` setting affects whether this item receives the notification. If useGroupRect is true, then this item will not receive the notification. Otherwise, the item receives the notification and notification bubbles up to the group.

      Specified by:
        `addClickHandler` in interface `HasClickHandlers`
      Parameters:
        `handler` - the click handler
      Returns:

          public com.google.gwt.event.shared.HandlerRegistration addDoubleClickHandler(DoubleClickHandler handler)

      Add a doubleClick handler.

      Notification fired when the user clicks on this DrawItem twice in rapid succession (within the `DrawPane`'s `doubleClickDelay` by default) in this object.

      Note that if this item is part of a `DrawGroup`, then the group's `useGroupRect` setting affects whether this item receives the notification. If useGroupRect is true, then this item will not receive the notification. Otherwise, the item receives the notification and notification bubbles up to the group.

      Specified by:
        `addDoubleClickHandler` in interface `HasDoubleClickHandlers`
      Parameters:
        `handler` - the doubleClick handler

          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

    - #### 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
      See Also:
        `SGWTProperties`

      If `proportionalResizing` is set to `ProportionalResizeMode.MODIFIER` or `ProportionalResizeMode.MODIFIER_OFF` then proportional resizing of the DrawItem is activated or deactivated, respectively, whenever at least one key in this set of modifier keys is pressed.

      The keys allowed in this set are: "Alt", "Ctrl", and "Shift". If this set of keys is empty then proportional resizing is always used if `proportionalResizing` is `MODIFIER` and is never used if `proportionalResizing` is `MODIFIER_OFF`.

      Parameters:
        `proportionalResizeModifiers` - Default value is ["Shift"]
