Hi,

I've got a strange behavior in QScrollBox object.

Here is the steps that I did.

I create new form. The form has the QScrollBox and QFrame object. The
QFrame object contain some layouts and components. Sometime I have to
put the QFrame object to the viewport() of the QScrollBox. I do follow

        QScrollView* scWin; // the QScrollBox object
        QGridLayout* scWinViewPortLayout;
        QFrame* fra_EdtReg; // the QFrame object
        ..........
        .....
        

        scWinViewPortLayout = new QGridLayout( scWin->viewport(), 1, 1, 11, 6, "scWinLayout");
        
        scWin->addChild(fra_EdtReg);
        scWinViewPortLayout->addWidget(fra_EdtReg, 0, 0);
        scWinViewPortLayout->setOrigin(QGridLayout::TopLeft);

Then I get following:

First, I can't see very bottom of the frame

Second, if I scroll vertical scroller to the very end of the
QScrollView and then I maximize the window I get wrong positioned
scroller and offseted (0,0) corner (It's moved a bit down)

What wrong I do?????
What should I do to have right results????
