Re: gtk_container_remove - issues

[Joseph Turner <joeman leederville net>]

Hello,
In regards to gtk_container/destroy bits.
I think I understand what you are talking about. Notes I've looked at on 
the web say that this will destroy the widget (unless special measures 
are taken to stop this).

I've tried replacing with gtk_widget_destroy and get the same 'Critical'
warnings. 

The warnings don't mention what widget they are referring to, doesn't
seem to be an easy way to determine what part of my program
they are actually referring. IS there a way to trace what widgets
are getting destroyed? 

I've tried some of the code below

GList *list;
GtkWidget *wid;
list = gtk_container_children(GTK_CONTAINER(widget));

while ( list ) {
wid = GTK_WIDGET(list->data); 

if GTK_IS_VBOX(wid)
  {
   g_print("We have a vbox!!\n");    
   if (GTK_IS_CONTAINER(wid))         
     {
      g_print("vbox is a container!\n");
      debug_container_widgets(wid);
     }
   //gtk_widget_destroy(wid);
  }
if GTK_IS_SHEET(wid)
  {
   g_print("We have a sheet!!\n");
   g_object_unref(G_OBJECT(wid));
  // gtk_widget_destroy(wid);
  }                 
if GTK_IS_TEXT_VIEW(wid) g_print("We have a Text View!!\n");



list = list->next;
}


to try and determine what is happening, but it is hard to determine 
_where_ the error is actually coming from.


Cheers

Joe
