I have designed my application using Glade and python , I have used many expander in vertical boxes with various buttons in each expander , I want to expand only one expander when I click on that and close(contract) automatically the previous open expander Is it possible to implement if yes then how .
Please suggest me how can I implement that .

Hello.

This is possible to achieve by monitoring GtkExpander:expanded property. Relevant part of the code would look something like this:

Code: (C)
1 2 3 4 5 6 7 8 9 10 11 12 13	g_object_connect( G_OBJECT( expander ), "notify::expanded", G_CALLBACK( cb_notify_expanded ), data ); static void cb_notify_expanded( GObject expander, GParamSpec pspec, gpointer data ) { if( gtk_expander_get_expanded( GTK_EXPANDER( expander ) ) ) { /* Close previously opened expander */ } }

Thank you very much
but on which signal of expander I should add this code.
Is there any similar code in python ?? that I could add on the handler [b]on_expander_activate[/b]
