rowCount does not change after removing one line widgets

[feiyuhuahuo]

I have such a QGroupBox, its layout is QGridlayout.

The rowCount is 5 now in above image.
After I remove the final line of buttons, it shows correctly but the rowCount is still 5.

Is there any operation I missed?

@feiyuhuahuo You only remove the buttons, but not the row in the layout, right? Then the behaviour is correct.

Seems it's impossible to remove a certain row in a QGridlayout.
