Hi, I have a drawing area in which I can place two vertical lines (used as cursors) using mouse buttons 1+2. The cursors can be moved around from mouse motion events whilst holding down a button. I have set GDK_BUTTON_PRESS_MASK and GDK_POINTER_MOTION_MASK on the drawing area and connected 'motion_notify_event' and 'button_press_event' to my callbacks. Tested individually the button press and motion events are only detected whilst the pointer is in the drawing area as I would expect. With any button pressed however motion events continue to be produced when the pointer leaves the drawingarea. This also occurs with a similar routine in the "scribble" example under either gtk1.2 or gtk2.0 so seems to be expected behaviour. This isn't a problem but I am curious to know why this occurs. Sorry if this is obvious I'm new to all this. Nick Soffe.
