QDockWidget resizeDocks function

[ArkKup]

Hi,

I'm trying to programatically resize MainWindow dock widgets. I read that in Qt 5.6 resizeDocks function was introduced
http://doc.qt.io/qt-5/qmainwindow.html#resizeDocks

I did a quick test to see how it works (I'm using Qt 5.7.0):

resizeDocks({ui->blueWidget, ui->yellowWidget}, {20 , 60}, Qt::Vertical);
setCentralWidget(0);
setDockNestingEnabled(true);

resizeDocks({ui->blueWidget, ui->yellowWidget}, {20 , 60}, Qt::Vertical);
setCentralWidget(0);
setDockNestingEnabled(true);

To copy to clipboard, switch view to plain text mode 

Unfortunately its not working at all
Anyone knows whats wrong ? How to pragmatically resize dock widgets ?
