boundingRect() works as I would expect. Can you provide some sample code?
Rectangle {
width: 300
height: 300
objectName: "rect"
Text {
objectName: "text"
text: "foo"
}
}
QDeclarativeItem *rect = qobject_cast<QDeclarativeItem *>(view->rootObject());
qDebug() << rect->boundingRect();
QDeclarativeItem *text = rect->findChild<QDeclarativeItem *>("text");
qDebug() << text->boundingRect();
Output:
QRectF(0,0 300x300)
QRectF(0,0 24x17)
The first one is the rect of the top level item (and it matches what I
set in qml) and the second one is the text item's computed
width/height. So, the values are as I would expect.
