RE: dialog widget problem

[Matt Eisemann <meisemann dsrnet com>]

Somewhat related to below.  I have my dialog widget in its own function 
now.  Hence , all the callbacks and widget creation are in a single 
function .  Is this a bad idea?  See the code (simplified...taken out 
hopefully extraneous code)

VOID dialog_create(SHARED_WINDOW *tasks)
{
  GtkWidget *dialog_win;
  GtkWidget *dialog_label;
  GtkWidget *dialog_ok

  dialog_win = gtk_dialog_new();
  gtk_widget_set_usize(dialog_win, 250,250);
  dialog_label=gtk_label_new("WARNING some text here \n");
  dialog_ok = gtk_button_new_with_label("OK");
  gtk_box_pack_start(GTK_BOX(GTK_DIALOG(dialog_win)->vbox), dialog_label,
                               FALSE,FALSE,NO_PADDING);
  gtk_box_pack_start(GTK_BOX(GTK_DIALOG(dialog_win)->action_area), 
dialog_ok,
                               FALSE,FALSE,NO_PADDING);

  gtk_signal_connect_object(GTK_OBJECT(dialog_ok),"clicked",
 
                                        GTK_SIGNAL_FUNC(gtk_widget_hide)  
,GTK_OBJECT(dialog_win));
  gtk_signal_connect_object(GTK_OBJECT(dialog_win),"delete-event",
 
                                        GTK_SIGNAL_FUNC(dialog_delete_ev  
ent),NULL);
  gtk_signal_connect(GTK_OBJECT(dialog_win),"destroy",
 
                                        GTK_SIGNAL_FUNC(utics_destroy),N  
ULL);

  gtk_widget_show(dialog_ok);
  gtk_widget_show(dialog_label);
  gtk_widget_show(dialog_win);
  tasks->dialog_win = dialog_win;
  tasks->dialog_create = TRUE;

}

Here is the dialog_delete_event function.

gint dialog_delete_event(GtkWidget *widget,
                                    GdkEvent *event,
                                    gpointer data)
{
  g_print("dialog delete event occurred\n");
  gtk_widget_hide(widget);

  return(TRUE);
}

void destroy(GtkWidget *widget),
                  gpointer data)
{
  gtk_widget_hide(widget);

}


The gtk_signal_connect_object(GTK_OBJECT(dialog_ok),"clicked",
 
                                        GTK_SIGNAL_FUNC(gtk_widget_hide)  
,GTK_OBJECT(dialog_win));
works great without noticible problems but the other ones do not work. 
 When I try to close the window via the window manager, the menu for the 
window dissappears but the dialog box remains.  Any noticible reasons why? 
 Maybe the above code will help.  I want the dialog box to dissaprear and 
not be destroyed when the user closes the window via the window menu. 
 (command ALT - F4).  Any ideas why it is not working.  Thanks ahead of 
time for your help.

Matt

The code looks OK to me, however, you may be running into a scoping issue
with dialog_win depending on where you use gtk_signal_connect(). 
 Otherwise,
I think I'd need to see more of your code to figure out what's going on.
