public abstract class AbstractSWTWidgetFigure<T extends Control> extends org.eclipse.draw2d.Figure
The abstract figure for all SWT widget based figure. Note that there are some known issues regarding using SWT native widget in draw2D figure:
  • The order of SWT widget is always on top of draw2D figures. The order between between SWT widgets works but it is initialized during OPI startup, so change its order with change order action will only be reflected after reopen/run the opi.
  • Moving/Resizing a SWT widget is much slower than draw2D figure
