Grab Focus for Frame after Shortcut Pressed in wxPython on GNOME
原标题:

I m building an app that uses global shortcut keys (using python-keybinder), but there s a problem. The frame pops up and raises properly but doesn t have focus. I have to click on frame.

After I press my keyboard shortcut my frame appears, but it is not focused. I can see that the frame I was focused on previously (e.g. my Firefox frame) still has focus (i.e., the title bar is still white & bold). Only after I click on my app s frame does Firefox s title bar become grey and dim.

I try to SetFocus and CaptureMouse but neither do anything. FindFocus and GetCapture return None.

This only happens on Ubuntu (GNOME). On Windows, the frame gets focus immediately. Is there a way to force GNOME to give focus to my app/frame?

How are you showing the frmae initially, with frame.Show()? I m not sure if you re saying the frame itself doesn t have focus (but/or a child of the frame does), or your application doesn t have focus?

Are you calling SetFocus in the Frame that initialises all your widgets? It could be an issue of the focus being given to a child of the frame. Try using wx.CallAfter(self.SetFocus) at the end of your Frame.init method - it should ensure the focus is set after all widget creation is done
