I am thinking in my carpal fashion that centering sub-popup menus on an item
would be a good thing, if doable in a gtk app.
Half the wrist movement to go up or down. Better use of screen display area
etc. (and see tog's question's 6 and 8 at:
http://www.asktog.com/columns/022DesignedToGiveFitts.html
for more justifications)
But forget about the justifications for a bit, I'm trying to figure out
how to do it. If I were to write a
void (*GtkMenuPositionFunc) (GtkMenu *menu,
gint *x,
gint *y,
gboolean *push_in,
gpointer user_data);
and pass in, say, the name of the menu item to center around in user_data,
how would I go about getting the effective x and y offset from the top
of the menu of the menu item before its realized?
