Hi I try to do something that is similar to some 3D projection plan window rotating/shifting function: When a key is pressed, the relative mouse movement should be recorded.
I'm primary interested if somebody solved a similar problem or got an idea how to solve this. I like to use a Key-Combination to switch from usual mode to this special mode and back. The mode switch should work when the application has the focus. And it should not involve that a mouse button must be hold down.* I managed to use a Widget with its own window (GtkDrawable) to archive part of the job: If I click into the window and hold the mouse button I can even move the pointer out of the window while still receiving the mouse movements. But the pointer stops at the screen borders. I also noticed that I can get the mouse position in Desktop root window with gtk.gdk.Display.get_pointer(). But for obvious reasons the pointer cannot go out of the screen borders. I know there is a gdk_display_add_client_message_filter() function in the GTK C Library. This one may solve the problem. But before I invest time to try this out I like to hear your advice. The application is currently a pure PyGTK Python program. If the program is resolveable with PyGTK it's fine. If not, I'm open to write a C-Python module. Cheers, Andy * If you wonder what this is for: I'm writing an application to control lighting devices like Scanners and Moveingheads (and plan to release it under GNU Public Licence). The mouse movement capture mode is needed to control the Pan- and Tilt-Axis with the mouse or (better) a Trackball. _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
