RE: dialog widget problem

[Matt Eisemann <meisemann dsrnet com>]

Since were on the topic.  Actually that did not work at all.  I get a core 
dump when I do this.  The OK button stays depressed.  Maybe since I am 
doing a showall from another function, main does not know what objects were 
set to show_all.  Need to investiage further.

here you are calling the hide on the ok button itself - not the dialog, 
since
the signal_func passes the widget also .. one way you could remedy this is

gtk_signal_connect(GTK_OBJECT(dialog_ok), "clicked",
GTK_SIGNAL_FUNC(hide_dialog), dialog_win);

void hide_dialog(GtkWidget *button, GtkWidget *dialog_win)
{
	gtk_widget_hide(dialog_win);
	return;
}
