Size Grip for QMdiSubWindow on OSX

Hi all,

I'm having a heck of a time trying to make it possible to resize a QMdiSubWindow within an QMdiArea on OSX using Qt 5.1 download bundle.

I've seen bug #29434 which claims the issue is fixed and can verify that the fix is applied in the Qt 5.1 sources, but it appears that the 5.1 download bundle does not produce a size grip on any QMdiSubWindow I add to it, and thus no windows can be re-sized by the user. Looking through the code, it appears that QT_NO_SIZEGRIP is a compile-time option for the Qt source code. Does this mean I have to re-compile the Qt 5.1 release to enable Sizegrips for QMdiSubWindows on OSX, and does anyone know a reason why that would've been turned off by default on OSX? Or, is it instead, there is some other activity I must perform to add sizegrips to my QMdiSubWindows on OSX?

For example, none of the following QMdiSubWindows will have sizegrips on OSX using the Qt 5.1 download bundle:

Code:

---

MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow) {
    ui->setupUi(this);
 
    m_vbb = new VirtualBoardWidget(ui->mdiArea);
 
    m_vbbSw = new QMdiSubWindow;
    m_vbbSw->setWidget(m_vbb);
 
    QWidget* foo = new QWidget(this);
 
    foo->setBaseSize(100, 100);
 
    QLabel* bar = new QLabel(this);
 
    bar->setText("Test foo bar");
 
    ui->mdiArea->addSubWindow(m_vbbSw);
    ui->mdiArea->addSubWindow(foo);
    ui->mdiArea->addSubWindow(bar);
 
}

Thanks!

I am facing the same problem (even with the latest 5.4 version). Have you come up with a solution?
