[Glade-users] Best Practice for Glade.XML - open/close new window


Thanks for your help.  I've modified my code so that all of the windows are opened up at startup and then 
hidden/shown as needed.  This seems alot snappier than before and has helped in that regard.  However, it has 
caused a couple of problems.  The first, a minor problem, is that you can see all of the windows open up for 
a split second and then hide at startup.  Here's how each  window now gets created at init.  I'm keeping 
Gtk.Window references to each of the windows using this method:

protected Gtk.Window getWindowHandle(string sWindowName)
  Glade.XML gxml = new Glade.XML(sPATH_TO_GLADE_XML,sWindowName, null);
  gxml.Autoconnect (this);
  Gtk.Window wnd = (Gtk.Window)gxml.GetWidget(sWindowName);
  return wnd;

Is there a better way to create these windows, especially one that keeps them from being initially shown?  
Also, is there a better way to use the Glade.XML rather than creating/destroying for each window I want to 
open?  Can I reuse the same Glade.XML and ask it for different windows?

The second problem is that some of control references don't seem to work now.  I believe that the problem 
results from having named all my back and next buttons the same (btnBack, btnNext).  And now that I've 
Autoconnect()ed to each of the windows consecutively, the last in the list is the only one which remains 
connected.  Does that sound right?

Thanks for any advice.  Regards,

The reason I'm asking about this is that the app seems
slightly slow and has shown some funny behavior
between opening new windows.  Can anyone spot any
mistakes with this?

Each time I show a new window:
  gxml = new Glade.XML(sPATH_TO_GLADE_XML,
sWindowName, null);
  gxml.Autoconnect (this);
  wndCurrent =
  // ... set properties of wndCurrent ...

And when I'm done with the window:

Thanks for any advice. 

I think calling only wndCurrent.Destroy() should be enough (it should be disposed
and hidden as a side effect).. that is besides the point...

It will be faster if you create your windows once at initialization
and just show/hide them, alternatively; you are probably better off
with a GnomeDruid type of design; if GnomeDruid is not available to you;
you can simply use a GtkNotebook and hide the tabs, use forward/backward
buttons to navigate pages in your notebook.


Note that libglade does a two-pass parse; it parses the glade file into
internal structures and then builds the widgets based on these, the future
gtk builder should be faster in this respect.
