Subject: Support for menu bar in window_from_coordinates
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=6b229ffc6f32b111bf11242080d98022758b43e0;p=emacs.git

Support for menu bar in window_from_coordinates

* src/window.h:
* src/window.c (window_from_coordinates): In the no toolkit
build, add support for the menu bar window.  Add a new
'menu_bar_p' argument so the function's signature has changed.
All callers changed.

* src/androidterm.c (handle_one_android_event):
* src/haikuterm.c (haiku_read_socket):
* src/keyboard.c (make_lispy_position):
* src/nsterm.m ([EmacsView mouseDown:]):
* src/pgtkterm.c (button_event):
* src/w32term.c (w32_read_socket):
* src/xdisp.c (note_mouse_highlight):
* src/xterm.c (handle_one_xevent): Set menu_bar_p to true.
