Tried that too, to no avail
static void activateLayoutsRecursive(QObject *objectP)
{
if (objectP) {
for (auto* childP: objectP->children()) {
activateLayoutsRecursive(childP);
}
QWidget*
widgetP(dynamic_cast<QWidget*>(objectP));
if (widgetP) {
widgetP->updateGeometry();
QLayout* layoutP(widgetP->layout());
if (layoutP) {
layoutP->invalidate();
layoutP->update();
layoutP->activate();
}
}
}
}
