Re: Gtk::Label doesn't refresh..

[Luca Cappa <luca cappa i-medlab com>]

Hello,

you could either run this code

while( Gtk::Main::events_pending() )
        Gtk::Main::iteration (false);

everytime after the set_text call,

or instead

label.invalidate ();
label.update ();

to force iredrawing immediately only fo rthe label.

Greetings,
Luca
