Class DoubleClickTrigger

java.lang.Object
oracle.ide.controls.DoubleClickTrigger

public class DoubleClickTrigger

extends java.lang.Object

This class is used for detecting the occurence of a double-click. For the purposes of this class, a "double-click" is the occurence of two MouseEvents corresponding to the mouse1 button without any modifier keys being pressed.

The detection of double-click is mediated by the isDoubleClick(MouseEvent) method. All mouse events for a particular MouseListener must be forwarded to isDoubleClick(MouseEvent) for processing in order for the proper sequence of clicks to be detected.

The implementation of isDoubleClick(MouseEvent) is somewhat unforgiving, since it will return true only when the click count is a multiple of 2, so long as the last two clicks were mouse1 clicks without modifier keys.
