Hi
I have a window with some buttons and a status bar.
When i click one of the buttons this starts a lengthy operation.
I would like to have a message like "loading data..." appear
on the status bar as soon as i press the button.
This is what i do:
void IQWin::on_button_load_data_clicked() {
m_Status.push("loading data...");
while (Gtk::Main::events_pending ())
{
Gtk::Main::iteration ();
}
m_IQScene.loadData(m_txtDataFile.get_text().c_str());
}
But that way the message on the status bar only appears when
the function has completed (after all the data has been loaded).
I guess by starting a thread which does the loading i could solve this problem,
but is there a more simple way to do this?
Thank You
Jody
