Avoid resizing GtkStatusbar if the text of the label changes (#90955, He
2004-11-09 Matthias Clasen <mclasen@redhat.com> Avoid resizing GtkStatusbar if the text of the label changes (#90955, He Qiangqiang, fix proposed by Owen Taylor, patch by Christian Persch) * gtk/gtklabel.[hc]: Add a boolean single-line-mode property which causes the label height not to depend on the actual text, but only on the font. * gtk/gtkstatusbar.c (gtk_statusbar_init): Turn on single-line-mode for the label.
