调研方向

Start at the Linux implementation of Window::Restore() and trace its use of gdk_window_deiconify(), then inspect the window-state-event handling for iconified state. Compare the GNOME behavior with gtk_window_present_with_time() and verify that restoring a minimized window emits the restored event and that a later Show() does not report a spurious minimize event.

描述

bug

On Linux, Window::Restore() calls gdk_window_deiconify(), which Mutter ignores, so a minimized window isn't brought back and no restored event fires. It works on X11 window managers that honour it, but not on GNOME. Related: after the user minimizes a window, a later Show() can report a minimize event right away instead of showing it.

Possible fix: gtk_window_present_with_time() (with a real timestamp) when the window is iconified, and track the iconified state from window-state-event rather than from what was requested.

Background:

  • leanflutter/window_manager#525: window does not restore from minimization on Linux
  • leanflutter/window_manager#580: show() triggers an immediate minimize event after the user minimizes the window
