Snap to Grid and arrow keys [message #143822]

When snap to grid is enabled and the user uses the keyboard (i.e. '.' then
left/right/up/down arrow), is there a way to get one keystroke equal to one
grid spacing?

thanks,

Jody

Look at DragEditPartsTracker#handleKeyDown(KeyEvent). If an arrow key is
pressed (acceptArrowKey(e)), it determines the amount by which to move the
part by invoking accGetStep(). You'd have to override this default
behaviour IFF the grid is enabled. Since accGetStep is package protected,
just override handleKeyDown and move the mouse by horizontal or vertical
grid spacing. You'll have to do the same for ResizeTracker if you want the
same effect during resizing.
