Yes, I'm getting there, slowly :-)

Pretty!


Although for my use of LanguageSettings
(quick lang. choice before a popup)
I'd go for a something that can show all
the languages on one page (multi text column).

Agreed, but in terms of the API, it could _seem_ to.
I'm doing this (horrible hack) at the moment:

void SchemaUpgradeWizard::exit(void)
{
     gSelected = kDialogCodeButton0;
}

void SchemaUpgradeWizard::waitForDialogSelect(void)
{
     QEventLoop l;

     gSelected = -1;
     while (gSelected == -1)
     {
         l.processEvents(QEventLoop::AllEvents, 250);
         usleep(100);
     }
}

...

     dlg->AddButton(tr("Exit"), SLOT(exit()));
     dlg->SetReturnEvent((MythScreenType *)this, QString::null);
     waitForDialogSelect();



but that does nothing for LEFT or ESCAPE,
and it would need something different when
the main window event loop is running.
