Description Matthias Wienand CLA 2015-12-18 03:56:35 EST 
The AbstractFXOnClickPolicy can be used to process mouse clicks (i.e. mouse press events). However, these events can already be processed by an AbstractFXOnDragPolicy. The distinction between click and press-drag-release events was initially introduced to allow processing a mouse press event before the press-drag-release events are processed. However, in view of the currently ongoing refactoring of transaction/interaction handling (see bug #481810), we should investigate if this distinction is still necessary.

In JavaFX the MouseEvent#MOUSE_CLICKED event is only generated if the mouse remains stationary (within a threshold) for a short amount of time. However, other event data, such as the click count, can also be evaluated for MouseEvent#MOUSE_PRESSED events.
Comment 1 Alexander Nyßen CLA 2016-01-25 13:27:30 EST 
As we have decided to keep the differentiation between click and drag (at least for now), resolving this as INVALID.
