I have a modal QDialog, that on the click of a button slides a modeless child QDialog out from underneath it. The problem I have is that the child stays on top of its parent during the animation.
I think I could get away with applying a mask over the portion of the child that overlaps the parent, but it feels like I'm missing a more obvious way of just placing the child under the parent.
I'm using Qt 4.5. Here's some sample code:
void MainWindow::on_myMenu_triggered()
{
parentDlg = new QDialog(this);
parentDlg->setFixedSize(250, 250);
parentDlg->setModal(true);
parentDlg->show();
childDlg = new QDialog(parentDlg);
childDlg->setFixedSize(150, 150);
childDlg->show();
QTimeLine* timeLine = new QTimeLine(1000, this);
connect(timeLine, SIGNAL(valueChanged(qreal)), this, SLOT(childDlgStepChanged(qreal)));
timeLine->start();
}
void MainWindow::childDlgStepChanged(qreal)
{
int parentX = parentDlg->frameGeometry().x();
int parentY = parentDlg->geometry().y();
// Move the child dialog to the left of its parent.
childDlg->move(parentX - 150 * step, parentY);
}
Thanks in advance.
