2004-02-13 Federico Mena Quintero <federico@ximian.com> Fix #129020. * gtk/gtkfilechooserdialog.c (set_default_size): New function, sets a reasonable default size for the window. (gtk_file_chooser_dialog_realize): New function, call set_default_size(). (gtk_file_chooser_dialog_style_set): Likewise. (gtk_file_chooser_dialog_screen_changed): Likewise. * tests/testfilechooser.c (main): Don't set a default size for the dialog.
