Hallo,

Thanks for trying to help me.

Yes, I know this (there's only fileselection=NULL;
missing ;-) ) but the important question is, if all
GtkWidgets (Buttons, labels, drawing areas etc.) and
other created objects from another pointer are still
in memory? Because if I use ddd and display the
fileselection-Widget I can see all parameters after
destroying the fileselection-window normally. What is
the situation from this parameters and all objects
included in the window (especially created from
pointers with malloc)?

And if this objects in memory exists: How is it
possible to remove them from memory?

   Hallo,

   in my programm I've got the following global
pointer:
   +++
   GtkWidget *fileselectionfensterglobal;
   ++


   I created 3 signals to kill the window:
   +++
   void
   on_fileselectionfensterglobal_destroy  (GtkObject
    *object, gpointer         user_data)
    {
    ...
    gtk_widget_destroy (fileselectionfensterglobal);
   }

   void
   on_ok_buttonfileselection_clicked  (GtkObject
   *object, gpointer         user_data)
   {
    ...
    gtk_widget_destroy (fileselectionfensterglobal);
   }

   void
   on_cancel_buttonfileselection_clicked  (GtkObject
    *object, gpointer         user_data)
    {
    ...
    gtk_widget_destroy (fileselectionfensterglobal);
   }
   ++


   Somewhere in the programm I create the window:
   +++
     fileselectionfensterglobal =
     create_fileselectionfensterglobal ();
     gtk_widget_show (fileselectionfensterglobal);
     ++

   If I "destroy" the window with one of the signal
the
   window disappears. Ok so far.

   But I think the windows is still in memory because
the
   following code is not true:
   +++
   if (fileselectionfensterglobal == NULL){...}
   ++

   My question now: How can I completely remove the
   fileselectionwindow (or other windows ;-) ) with
all
   Widgets (Buttons etc.) in it from memory because if
I
   use the function create_fileselectionfensterglobal
()
   again the old fileselectionwindow-data ist still in
   memory but I do not want to use it anymore!

   Perhaps you can give me an example-code for my
problem
   above.

   Thanks for your help!
   Bye

   Christian Schneider
