I would be very grateful for any assistance here.
Q/ How do I get a CanvasItem position information to update when I move
it?
I can move things but their position info seems to remain unchanged!
I can't find the answer to this particular problem though there is a lot
of info out there....
Setting up some test routines on a gnome-canvas
when moving widgets using event drivers and the mouse.
For a rectangle I have ...
the original location-
('rect',x1=x1,y1=y1....etc
and can see the location info by -
widget['x1'] etc
and using an event driver to do-
widget.move(x,y)
but widget['x1'] etc are not updated and only hold the original widget
coordinates.
I can only get the coordinates to update using
widget.set(x1=newx1,x2=newx2...etc
I presume I am missing something.
It gets worse if I try and group things since it is rather
troublesome to have to explicitly set multiple grouped widgets.
So - how do I get the position information to update when a widget
moves?
thanks if you can spare the time
