Field Summary

static boolean

hack A flag, indicating whether or not a very dirty initialization on created RepaintManagers must be performed.

Method Summary

static boolean	addDirtyRegion(JComponent aComponent, int x, int y, int w, int h, RepaintManager manager) Searches upwards in the component hierarchy for a JXLayer ancestor with an enabled TransformUI.
static void	hackInitialization(RepaintManager sourceManager, RepaintManager destinationManager) If hack is true, the private fields paintManager and bufferStrategyType are copied via reflection from the source manager into the destination manager.

hack

public static boolean hack

A flag, indicating whether or not a very dirty initialization on created RepaintManagers must be performed.

Method Detail

addDirtyRegion

public static boolean addDirtyRegion(JComponent aComponent,
                                     int x,
                                     int y,
                                     int w,
                                     int h,
                                     RepaintManager manager)

Searches upwards in the component hierarchy for a JXLayer ancestor with an enabled TransformUI.

If found, the dirty rectangle is transformed to a rectangle targeted at that JXLayer and the argument manager's RepaintManager.addDirtyRegion(JComponent, int, int, int, int) is invoked. true is returned.

Else, (@code false} is returned.

Parameters:

aComponent - a component

x - the X of the dirty region

y - the Y of the dirty region

w - the width of the dirty region

h - the height of the dirty region

manager - the current RepaintManager

Returns:

true if the call is delegated to the manager with a transformed rectangle, false otherwise

hackInitialization

public static void hackInitialization(RepaintManager sourceManager,
                                      RepaintManager destinationManager)

If hack is true, the private fields paintManager and bufferStrategyType are copied via reflection from the source manager into the destination manager.

Parameters:

sourceManager -

destinationManager -
