Federico Mena Quintero fff4999699 Fix #129020.
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.
