                                                   java.awt.geom.Rectangle2D rect)
        Description copied from interface: DesignableDelegate
        Fetch the current bounds of the given item, relative to the supplied JComponent. If the rect argument is null, a new Rectangle should be instantiated and returned. Otherwise, rect should be modified and returned to avoid unnecessary Rectangle instantiation, because this function is called very frequently.
        Specified by:
        getBounds in interface DesignableDelegate
      • initRect

        protected java.awt.geom.Rectangle2D initRect​(java.awt.geom.Rectangle2D rv,
                                                     java.awt.geom.Rectangle2D copyFrom)
        Initializes a return value rectangle rv, or creates a new one if it's null. If copyFrom isn't null, then the rect is set to that size.
      • getShapeBounds

        public java.awt.Shape getShapeBounds​(javax.swing.JComponent item,
                                             javax.swing.JComponent relativeTo,
                                             java.awt.Rectangle rect)
        Description copied from interface: DesignableDelegate
        Return non-rectangular bounds of the given item relative to the supplied JComponent. If the bounds happen to be rectangular, you may alter the supplied rectangle to avoid instantiating a new shape.

        getShapeBounds in interface DesignableDelegate
      • getOffsettingParent

        public javax.swing.JComponent getOffsettingParent​(javax.swing.JComponent source)
