Hi Felipe!
This is not related to window manager as it's a separate process.
Simply changing
attributes is done through event mechanism.
Consider this application:
#include <QtGui>
int main (int argc, char **argv)
{
QApplication app(argc, argv);
QMainWindow win;
win.show();
QMessageBox::StandardButton reply;
reply = QMessageBox::warning(&win,
QObject::tr("Title"), QObject::tr("Message"),
QMessageBox::Yes | QMessageBox::No);
if (reply == QMessageBox::Yes) {
win.setAttribute(Qt::WA_Maemo5ShowProgressIndicator, true);
app.processEvents();
sleep(5);
win.setAttribute(Qt::WA_Maemo5ShowProgressIndicator, false);
}
return app.exec();
}
Thanks, Daniil.
