[Qt-interest] Extracting MDI windows

[lbutler3]

Is there a way to extract windows from an MDI area and promote to full windows in the application?

I've tried the following:

void MainWindow::on_actionNew_triggered()
{
    m_textwins.append(new QPlainTextEdit(ui->mdiArea));
    ui->mdiArea->addSubWindow(m_textwins.last());
    m_textwins.last()->show();
}
void MainWindow::on_actionExtractMDI_triggered()
{
    QMdiSubWindow *sw = ui->mdiArea->currentSubWindow();
    QWidget *win = sw->widget();
    win->setParent(this, Qt::Dialog);
    win->show();
    ui->mdiArea->removeSubWindow(sw);
}

which seems to work until the re-parented QPlainTextWindow is resized, when another window magically  appears.  This new window seems to be a new application window without the application menus attached.

Any suggestions would be welcome.
