Hello David,
I think you could make the mouse pointer cursor invisible and when you
detect a mouse movement (after you started somehow the "pan" process),
just put the mouse in the original position: in this way you could move
the mouse as long as you wish.
Using XLib in Linux, the code to set the mouse position could be:
//
//Place the mouse to the original position (i.e. to mPressPoint).
Glib::RefPtr<Gdk::Window> lWin = get_window ();
Window win = GDK_WINDOW_XID (lWin->gobj ());
Display *dpy = GDK_WINDOW_XDISPLAY (lWin->gobj ());
XWarpPointer(dpy, None, win, 0, 0, 0, 0,
mPressPoint.x,
getWidgetSize ().y - mPressPoint.y - 1);
Hope this helps,
Luca

Hi,
I want to pan a bitmap in a drawing area. But I don't want the maximum
pan distance to be limited by the screen size. Is there any way to make
GTK emit mouse motion events after the pointer reached the screen border?
Thanks for your help,
