Windows menu rollover: first menu can't click?

[davecotter]

see this lovely movie:

any idea about that?
the screen is at 200% (HiDPI)

there is nothing invisible in the UI at that location, see my ui file here:

the menus are created programmatically, there is nothing special about the first menu

any idea why it won't respond to clicks or roll overs?

@Chris-Kawa said in Windows menu rollover: first menu can't click?:

a.topLevelWidgets().front()->dumpObjectTree()

that was very helpful! the output hinted at a sub (context) menu (which should be invisible). indeed, the owner object of all context menus was visible! i hid it, and boom, all fixed! wow thanks!

Looks like there's something there after all. Maybe something added from the code. It probably works on drag because it grabs mouse on mouse press.

An easy test to do:

qApp->setStyleSheet("QWidget { border: 1px solid red; }");

or

qDebug() << qApp->widgetAt(qApp->topLevelWidgets().front()->mapToGlobal(QPoint(5,5)));

I humbly bow before your insane ninja skills!!!

Now how do i figure out just what it is that's at that spot??

i tried this:

But that just prints an empty line in the console :/

whatsThis() is only set if you set it. That's not gonna be useful here.

qDebug will print the class and object name. You're just missing #include <QDebug> to use it.
Alternatively you can do a.topLevelWidgets().front()->dumpObjectTree(); and dig through the output to see what shouldn't be there.
Yet another way is to set a breakpoint and inspect whatP in the debugger. It might reveal its class, object name or other useful info that will lead you to the source of it.
