Method Detail

clear

public void clear(java.awt.Graphics g)

Description copied from interface: DragRenderer

clears whatever renderDrag rendered. This is not used by the DasMouseInputAdapter, but must still be supported for now. Originally the drag renderer would have to unpaint itself as well, but this is no longer used.

Specified by:

clear in interface DragRenderer

Overrides:

clear in class BoxRenderer

Parameters:

g - the graphics context

idType

protected static BoxZoomGesturesRenderer.Type idType(DasCanvasComponent parent,
                                                     java.awt.Point p1,
                                                     java.awt.Point p2)

public java.awt.Rectangle[] renderDrag(java.awt.Graphics g1,
                                       java.awt.Point p1,
                                       java.awt.Point p2)

Description copied from interface: DragRenderer

draws the drag for mousing from p1 to p2, and returns an array of Rectangles covering the rendering. If nothing is drawn, then an array of length zero should be returned, and nulls are allowed in the array. p1 and p2, and g are in the canvas frame of reference.

Specified by:

renderDrag in interface DragRenderer

Overrides:

renderDrag in class BoxRenderer

Parameters:

g1 - the graphics context for rendering

p1 - the click point

p2 - the current mouse position during drag and release.

Returns:
