Re: [fltk.coredev] Re: take_focus or focus(this) on Linux raises the Fl_Gl_Window - Forums

You may be at the mercy of the idiots designing X window managers. The idea that you could type to a window that is not on top apparently bothers them and they are doing everything they can to make it impossible. It is now significantly worse than Windows.

For the keystrokes fltk could just fake it by not telling the os anything and internally delivering all keystrokes to the window the programmer wants. It can also be done without changes to fltk by putting a keystroke handler on every window, or using global shortcuts, having them decide what to do based on what window the mouse is in.

Most likely the window raises when clicked on as well, and there is absolutely no way to stop this.

Oh yes. This is on X11 under GNOME.
