Problem with widget

[SPlatten]

I'm having a problem with a widget so in an effort to see what is going on I want to add an additional rectangle to the widget so I can render debug information to this new rectangle.

In the paintEvent I get the geometry:

QRect rctGeom(rect());
#if defined(TRUTH_DEV)
if ( mblnVisibleCopy == true && mrctDev.isEmpty == true ) {
//Adjust widget geometry allowing for the development area
    int intWidth(rctGeom.width());
    rctGeom.adjust(0, 0,intWidthh, 0);
qDebug() << "BEFORE: " << rctGeom;
    setGeometry(rctGeom);
qDebug() << "AFTER: " << geometry();
    mrctDev = rctGeom;
    mrctDev.adjust(intWidth, + 40, intWidth, -40);
qDebug() << "rctGeom: " << rctGeom << ", mrctDev: " << mrctDev;
}
#endif

The output from above is:

BEFORE: QRect(0,0 416x644)
AFTER: QRect(0,0 208x644)
rctGeom: QRect(0,0 416x644), mrctDev: QRect(208,40 416x564)

I'm not sure why the geometry in the AFTER message has a narrow width after calling setGeometry.
[Edit], I just tried:

QRect rctGeom(rect());
#if defined(TRUTH_DEV)
if ( mblnVisibleCopy == true && mrctDev.isEmpty == true ) {
//Adjust widget geometry allowing for the development area
    int intWidth(rctGeom.width());
qDebug() << "BEFORE: " << rctGeom;
    resize(intWidth*2, rctGeom.height());
qDebug() << "AFTER: " << geometry();
    mrctDev = rctGeom;
    mrctDev.adjust(intWidth, + 40, intWidth, -40);
qDebug() << "rctGeom: " << rctGeom << ", mrctDev: " << mrctDev;
}
#endif

Now the output is:

BEFORE: QRect(0,0 208x644)
AFTER: QRect(897,32 208x644)
rctGeom: QRect(0,0 208x644), mrctDev: QRect(208,40 208x564)

I'm very confused.

@SPlatten
possibly:

The size component is adjusted if it lies outside the range defined by minimumSize() and maximumSize().

@J-Hilk , thank you, modified to:

QRect rctGeom(rect());
#if defined(TRUTH_DEV)
if ( mblnVisibleCopy == true && mrctDev.isEmpty == true ) {
//Save current size
    Size szCurrent(size()), szNew;
//Adjust maxmum size to prevent geometry being rejected
    szNew.setWidth(szCurrent.width() * 2);
    szNew.setHeight(szCurrent.height());
//Adjust widget geometry allowing for the development area
    qDebug() << "BEFORE: " << rctGeom;
    resize(szNew);
    rctGeom = geometry();
    qDebug() << "AFTER: " << rctGeom;
    mrctDev = rctGeom;
    mrctDev.adjust(szCurrent.width(), + 40, szCurrent.width(), -40);
qDebug() << "rctGeom: " << rctGeom << ", mrctDev: " << mrctDev;
}
#endif

Results:

BEFORE: QRect(0,0 208x644)
AFTER: QRect(897,32 416x644)
rctGeom: QRect(897,32 416x644), mrctDev: QRect(1105,72 416x564)

Thank you!
