Re: How do I flush signals and gray out a menu item?

[Xavier Fuentes <furax linuxfreak com>]

Hi,

You should declare a function like this:

void ProcessEvents()
{
    while(gtk_events_pending())
        gtk_main_iteration();
}

then you call it every where you want signals to be processed.
to gray out menu items you should use this:

gtk_widget_set_sensitive(menu_item,false);

it also work for any widgets.


friendly,
Xavier
