Re: GTK Modal dialog

[John Cupitt <jcupitt gmail com>]

This test program woks for me on windows and linux with gtk+-2.4.9.
But maybe I misunderstand your problem?

- the dialog does not appear on the taskbar
- when the dialog is open the main window button does not work (so you
can never have more than one dialog)
- the dialog is always above the main window

-------------------
#include <gtk/gtk.h>

static void
dialog_button_click( GtkWidget *widget, GtkWidget *dialog )
{
        gtk_widget_destroy( dialog );
} 
  
static void
window_button_click( GtkWidget *widget, GtkWidget *parent_window )
{
        GtkWidget *dialog;
        GtkWidget *button;

        dialog = gtk_window_new( GTK_WINDOW_TOPLEVEL );
        button = gtk_button_new_with_label( "done" );
        g_signal_connect( G_OBJECT( button ), "clicked",
                G_CALLBACK( dialog_button_click ), dialog );
        gtk_container_add( GTK_CONTAINER( dialog ), button );

        gtk_window_set_modal( GTK_WINDOW( dialog ), TRUE );
        gtk_window_set_transient_for( GTK_WINDOW( dialog ),
                GTK_WINDOW( parent_window ) );
        gtk_window_set_position( GTK_WINDOW( dialog ),
                GTK_WIN_POS_CENTER_ON_PARENT );

        gtk_widget_show_all( dialog );
}

int
main( int argc, char **argv )
{ 
        GtkWidget *window;
        GtkWidget *button;

        gtk_init (&argc, &argv);

        window = gtk_window_new( GTK_WINDOW_TOPLEVEL );
        button = gtk_button_new_with_label( "click to open dialog" );
        g_signal_connect( G_OBJECT( button ), "clicked",
                G_CALLBACK( window_button_click ), window );
        gtk_container_add( GTK_CONTAINER( window ), button );
        gtk_widget_show_all( window );

        gtk_main();

        return( 0 );
}
