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.

Specified by:

clear in interface DragRenderer

getMouseDragEvent

public MouseDragEvent getMouseDragEvent(java.lang.Object source,
                                        java.awt.Point p1,
                                        java.awt.Point p2,
                                        boolean isModified)

This method is called by the DMIA on mouse release. We use this to infer the mouse release and hide the Window. Note this assumes isUpdatingDragSelection is false! TODO: DMIA should call clear so this is more explicit.

Specified by:

getMouseDragEvent in interface DragRenderer

isPointSelection

public boolean isPointSelection()

Description copied from interface: DragRenderer

indicates that MM.mousePointSelected() should called as new mouse events come in.

Specified by:

isPointSelection in interface DragRenderer

isUpdatingDragSelection

public boolean isUpdatingDragSelection()

Description copied from interface: DragRenderer

range selection events should be fired during drag.

Specified by:

isUpdatingDragSelection in interface DragRenderer

setLabel

public void setLabel(java.lang.String s)

renderDrag

public java.awt.Rectangle[] renderDrag(java.awt.Graphics g,
                                       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:
