Subject: Don't call gtk_window_set_geometry_hints() if there are no hints to set.
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/5da0507745a4edeee7cfa899721bd34699cf19d3

Don't call gtk_window_set_geometry_hints() if there are no hints to set.

Calling gtk_window_set_geometry_hints() with the hints mask of 0 doesn't work
correctly and sets the window size to the smallest possible. Avoid this by
simply not calling this function at all if there is nothing to do.
