[Java-gnome-developer] Glade and reusing a window

[Stefan P. <pr...@tz...>]

Hi all,

I have some problems using Glade for dialogs. I guess I'm on a wrong
track somewhere, but I can't figure out where.

I have built a smale glade application with two windows - a normal one
(mainWindow) and a dialog window (adventWindow).  I load them like that
      glade = new LibGlade("dsadb-tool.glade", this);
      mainWindow = (Window) glade.getWidget("MainWindow");

At first that lead to both windows showing up immediatly, but I figures
that setting adventWindow to invisible stopped that.

mainWindow contains a menu and one menu option triggers the display of
the dialog window:

  public void on_abenteuer_activate() {
    System.out.println("on_abenteuer_activate");
    adventWindow = (Window) glade.getWidget("AdventWindow");
    adventWindow.show();
  }

Fine so far. The adventWindow-Dialog has a cancel button to close the
dialog again. It also has the usual button "x" on (the top right) window
frame to close the window. The cancel button triggers a call to 
  adventWindow.hide()
which works fine and allows me to call the show method again (even
without re-retrieving the widget from Glade).

My problem is: If I close the window with the "x"-Button on the frame
the window closes but cannot be re-used.

(java-gnome:32635): GLib-GObject-CRITICAL **: g_object_ref: assertion
`G_IS_OBJECT (object)' failed
(java-gnome:32635): GLib-GObject-WARNING **: instance of invalid
non-instantiatable type `glong'
(java-gnome:32635): GLib-GObject-CRITICAL **: g_signal_emit_valist:
assertion `G_TYPE_CHECK_INSTANCE (instance)' failed

`G_IS_OBJECT (object)' failed
(java-gnome:32635): GLib-GObject-CRITICAL **: g_object_unref: assertion
`G_IS_OBJECT (object)' failed

I guess the glade instance of the window has been destroyed and cannot
be reclaimed. I figured that I need to reload the whole glade file
again, which is not very satisfying.

What can I do to prevent this from happening? Or is there at least a way
to disable the "x" button for the window?

Regards,
  Stefan
