Method Detail

calculateOffset

private void calculateOffset()

createDirectionalIcons

private void createDirectionalIcons(java.awt.image.BufferedImage northIcon)

dragComplete

public void dragComplete(boolean success)

Description copied from class: DrawHandle

Called when the user has completed dragging (e.g. on mouse-button-release.) It is appropriate to add an undo event.

Overrides:

dragComplete in class DrawHandle

Parameters:

success - Whether the action was successful (and therefore should be stored in the UNDO history).
