[QTBUG-25999] QDeclarativeView bug...

Peppy

Hi guys, I have discovered bug that crashes my app. I would like to hear from you if it's my fault or not...

@
// main.cpp:
qmlRegisterType<MainWindow>("MainWindow", 1, 0, "MainWindow");

QDeclarativeView view;
view.setSource(QUrl::fromLocalFile&#40;"qml/app/main.qml"&#41;&#41;;
view.show();

@

@
// main.qml:

import QtQuick 1.1
import MainWindow 1.0

MainWindow
{
width: 100
height: 100
}
@

Where MainWindow is a subclass of QGraphicsWidget (or QDeclarativeItem, it doesn't matter)...

@
QMetaProperty::read: Unable to handle unregistered datatype 'QGraphicsLayout*' for property 'QGraphicsWidget::layout'
HEAP[App.exe]: Invalid address specified to RtlValidateHeap( 01460000, 015C6F08 )

When do you get this bug ?

Peppy

After closing window -> calling destructor of QmlDesktopViewer ...

Can you explain me what is it message:
@
LEAK: 226 Structure
@
and
@
LEAK: 217 Structure
@

? Not very talkative message :DD ... well it's buffer overflow somewhere, I think...

Hm, recently I am getting a lot of similarly enigmatic messages from QtQuick 2.0 in Qt Creator...

I have pushed it as a bug [QTBUG 25999]...
