QMdiArea unwanted actvation

[jpn]

Just to make sure the problem does not come from my code I checked another app using the same QMdiArea nesting and was able to reproduce the bug...

I somehow expected this to be a minimal compilable example or something like that.

Does anyone have a magic trick or do I need to go on the tracker and wait for a couple of releases to have it fixed?

The "magic trick" goes here:

class InnerMdiArea : public QMdiArea
{
public:
    InnerMdiArea(QWidget* parent = 0)
        : QMdiArea(parent) { }
 
    bool eventFilter(QObject* object, QEvent* event)
    {
        return event->type() == QEvent::ApplicationActivate
            || event->type() == QEvent::ApplicationDeactivate;
    }
};

class InnerMdiArea : public QMdiArea
{
public:
    InnerMdiArea(QWidget* parent = 0)
        : QMdiArea(parent) { }

    bool eventFilter(QObject* object, QEvent* event)
    {
        return event->type() == QEvent::ApplicationActivate
            || event->type() == QEvent::ApplicationDeactivate;
    }
};

As the class name suggests, use this as the inner MDI area and everything should be fine.

PS. The reason this works is that QMdiArea installs an event filter on QApplication and QObject::eventFilter() is virtual..
