isForceRedrawOnMousePressed

public boolean isForceRedrawOnMousePressed()

Description copied from interface: InputHandler

Indicates whether a redraw is forced when the a mouse button is pressed. Touch screen devices require this so that the current position and selection are updated when the button is pressed. The update occurs naturally on non-touch screen devices because the motion of the mouse prior to the press causes the current position and selection to be updated.

Specified by:

isForceRedrawOnMousePressed in interface InputHandler

Returns:

true if a redraw is forced when a button is pressed, otherwise false.
