Subject: 24.0.95; gtk_window_parse_geometry warning
Date: Wed, 04 Apr 2012 16:00:10 -0400

When emacs is built with gtk3 and the window geometry is specified on the command line or in .Xdefaults, the following warning appears in the terminal from which emacs was started:

Gtk-WARNING **: gtk_window_parse_geometry() called on a window with no visible children; the window should be set up before gtk_window_parse_geometry() is called.

To reproduce:

1. Build emacs with the configure option --with-x-toolkit=gtk3.

2. emacs -Q --geometry=80x34+340+40 &

I don't know enough about gtk to know whether this warning can safely be ignored, but here's a quote from the source file gtk/gtkwindow.c in which gtk_window_parse_geometry is defined:

 * Note that for gtk_window_parse_geometry() to work as expected, it has
 * to be called when the window has its "final" size, i.e. after calling
 * gtk_widget_show_all() on the contents and gtk_window_set_geometry_hints()
 * on the window.

This is a false warning. There are known issues with the rows in the geometry given to Emacs (you may get less rows than you ask for) but the positions are AFAIK more or less correct (i.e. both Gtk and the window manager modifyes it in an effort to keep the window onscreen).  I don't know why they added this warning in Gtk+ 3, the code is more or less the same as in Gtk+2.

Now, if you have a case where the window position is much different from the geometry given, that would be a real bug.

OK, thanks for the information.  I'm closing the bug.

Now that gtk3 is used by default, this warning is likely to annoy more 
and more users.  Is there a way to suppress it?  Are other people seeing 
it and simply ignoring it?

I added code to supress the warning.
