Gtk::Notebook set_current_page not redrawing

[Cesc <cesc santa gmail com>]

Hi,

 

I am experiencing a refresh/redraw problem when trying to set the active tab in a Gtk::Notebook with set_current_page, in gtkmm 2.4.

 

I have in a Gtk::Window a Gtk::Notebook, with various tabs created at startup. These tabs are to become active when a controller receives a special event. When the event is received and the tab which needs to be activated is found, i use the set_current_page function.

The problem is that it won't refresh, till i do some manual action (like moving the mouse over the window, or moving the window ... ).

First i tried just calling the set_current_page ... no luck.

Then i also tried calling the queue_draw, show and so on for the widget which had to become active ... also for the notebook .. and even for the main window ... i guess i did  not try all the possibilities, but i did not manage to get it to work.

 

Any pointers would be highly appreciated.

 

Regards,

 

Cesc
