Considering that gdk_display_get_monitor_at_window() works though, the idea was to translate the fake coordinate in the appropriate monitor so that gdk_display_get_monitor_at_point() returns the correct monitor and menus can be placed and sized correctly. Another solution is to use the new xdg_positioner, for declarative positioning of child surfaces. AFAIK, this work is being done in <a class="bz_bug_link bz_status_NEW " title="NEW - GTK should let GDK position menus" href="show_bug.cgi?id=756579">bug 756579</a> and will be discussed at the hackfest in Toronto (as Jonas indicated). Meanwhile these patches here fix the problem without requiring the new protocol, so it may come useful either in master until the patches from <a class="bz_bug_link bz_status_NEW " title="NEW - GTK should let GDK position menus" href="show_bug.cgi?id=756579">bug 756579</a> eventually land in master, or in gtk-3-20 where the new protocol and xdg-shell v6 might not be backported. Anyway, I am not pushing either way, if someone complains about the menu being misplaced in Wayland (as in <a class="bz_bug_link bz_status_NEW " title="NEW - Certain menus display at wrong position in configured multi-monitor setups under Wayland" href="show_bug.cgi?id=764310">bug 764310</a>) these patches here can help. I am fine with closing this bug as a dupe of <a class="bz_bug_link bz_status_NEW " title="NEW - GTK should let GDK position menus" href="show_bug.cgi?id=756579">bug 756579</a> if you prefer.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
