I am using Pygtk in Python 2.7 and would like to set win.set_decorated(False) when the mouse is outside the window and win.set_decorated(True) when the mouse is over the window. How to do?

python gtk

  • Post the relevant code that has sff, so we know how to help

  • @Miguel, I believe that the code I have is irrelevant in this case, since the solution is based on the state of the mouse on the window, launching these two situations that I mentioned.

  • @Miguel, I made a mistake when posting the functions cited, I beg your pardon. I edited the post.

  • I’ll take a look. Ha ok so didn’t transfer it right?

  • @Miguel thanks. It’s about taking out the edges and the title bar of the window with the set_decorated based on the mouse being or not on the window.

There is a small bug but I will try to get around it. The event however is being detected.

import gtk

def mouse_enter(win, event):
    win.set_decorated(True)

def mouse_leave(win, event):
    win.set_decorated(False)

win = gtk.Window()
win.set_decorated(False)
win.connect('enter-notify-event', mouse_enter)
win.connect('leave-notify-event', mouse_leave)
win.connect('delete-event', gtk.main_quit)
win.show_all()
gtk.main()

The problem is that it identifies the mouse over borders and the window title bar as not over the window.

You can test that with win.set_opacity(0.5) in the mouse_leave() and win.set_opacity(1) in the mouse_enter(), instead of set_decorated()

  • True, the problem is to fix this title bar collapse as Leave-notify-Event is treating the title bar as outside the window. I am searching a lot here to try to fix this bug, but unsuccessfully yet. :(

  • It may not be possible. Have you seen this in a window? I don’t think I’ve seen this feature. However I’ll also see if I discover something

  • So I think it’s not impossible if I can map the coordinates of the screen and manipulate the window decoration based on that. But it may not be feasible, since I managed to do what I expect by clicking outside the window and returning with the decoration by clicking again on the window. It is much less costly in terms of processing.
