I know, there's GnomeCanvas, but I can't use it, it's buggy on win32. The problem is, when I'm trying to move a widget it starts shaking, like having a double. You can try it for yourself. > Where am I doing wrong? Is there any alternative? I've not tried your code, but this behaviour usually comes from some kind of feedback in absolute and relative positioning. The trick is to use screen coordinates. When you get button down, note the position of the widget and note the position of the mouse stored in button.x_root (the mouse position in absolute screen coordinates). When you get a drag event, compare the current position of the mouse to the stored position (again, use motion.x_root) to find how far the mouse has moved, then add that displacement to the original widget position and set that as the new widget position. Never read the current position of the widget being dragged during a drag and you won't get feedback. You'll find this kind of thing even more important when you add auto scroll, heh.
