Method Details

initialize

public void initialize(DesignPanel panel,
 DesignableContainer container,
 DesignableDelegate delegate,
 List<JComponent> selection)

Specified by:

initialize in interface ISelectionControl

Overrides:

initialize in class AbstractSelectionControls

initHandles

protected void initHandles()

newHandle

protected IHandle newHandle(int side)

dragStart

protected void dragStart()

dragEnd

protected void dragEnd()

dragged

protected void dragged(Point2D anchor,
 Point2D handle,
 Point2D drag,
 int modifiers,

scale

public static Rectangle2D scale(DesignPanel panel,
 DesignableDelegate delegate,
 List<JComponent> selection,
 Rectangle2D originalRectangle,
 Map<JComponent,Rectangle2D> originalBounds,
 Map<JComponent,Rectangle2D> scaledBounds,
 Point2D anchor,
 Point2D handle,
 Point2D drag,
 int side,
 boolean restrict,
 boolean snap,
 boolean keepAspectRatio)

Parameters:

originalRectangle - The overall bounding rectangle of all selected objects at the beginning of the scale operation. In unzoomed coordinates.

originalBounds - The original bounds of each selected object, relative to the interaction layer in unzoomed coordinates.

scaledBounds - A map containing the last set of scaled bounds for each object in unzoomed coordinates. On the first scale of a series, this should be a clone of the originalBounds.

anchor - The anchor point for the scale - this is the 'fixed point'

handle - The handle point that the drag point is compared against.

drag - The point that the current drag is at.

side - The side code that the anchor resides on.

restrict - Whether or not to restrict to parent bounds

snap - Whether or not to consider snapping to grid

keepAspectRatio - Whether or not to maintain original aspect ratios
