resize floating dock from code

[martinwag]

I'm trying to change the size of a floating dock from within the code (think: button "show details").

I've come up with the following, trying various combinations of this, on my custom widget and the parent dock widget:

    //this->resize(400, 300);
    //this->setFixedSize(400,300);
    //this->updateGeometry();
    //this->show();
    //this->update();

    if (dockWidget->isFloating() {
      //dockWidget->resize(400, 300);
      dockWidget->setFixedSize(400,300);
      //dockWidget->updateGeometry();
      dockWidget->show();
      dockWidget->update();
    }

all this does is change the size of my custom widget inside the dock, but never the size of the dock.

Any suggestion on how to do this?

That's not the floating widget. The floating widget is dockWidget->dockContainer()->floatingWidget(). In Linux it is a subclass of QDockWidget otherwise it is a subclass of QWidget.

Thanks, works

if ((dockWidget != nullptr) && dockWidget->isFloating()) {
  dockWidget->dockContainer()->floatingWidget()->resize(450, 400);
  dockWidget->dockContainer()->floatingWidget()->updateGeometry();
}
