Drawing problem, some area does not draw well on Windows machine.

Thanks for your reply.
Do you mean to use QtQuick2ApplicationViewer instead of QQuickView in main.cpp? Could you share your main.cpp code?
And I'm using qt 5.2.
Thanks and regards.

No, i was using QtQuick2ApplicaionViewer. I'll provide you the code tomorrow.

Thanks for your reply!
I hope to try it!

The qtquick2applicationviewer is automatically generated if you create a new QtQuick2 project. I'll try the same with QtQuickView now.

Alright, i have tested it with QtQuickView and it works fine, too. I'll provide you the code:

I would guess that it's a bug. Which QT version are you using?

haiying

Thanks very much for your sharing the code. I will try it later.
I also guess it is a bug.
I'm using Qt 5.2.0 MSVC2012 32bit.

Thanks again and regards!!!

onek24

Yes, try it out and tell me if it worked. It seems to be a bug if the same code doesn't work in Qt 5.2.0. There isn't such a big difference between 5.2.0 and 5.2.1. Also have you tried your project with a QQuickView, yet?

haiying

Hello, I tried your code, but still had the same problem.
Please see the below URL, the second picture is the result of your code.

Yes, I have tried my code, the first picture is the result of my code, the following code.

@QT += qml quick declarative webkit

SOURCES += main.cpp

RESOURCES += test.qrc

target.path = $$DESTPATH

qml.files = *.qml
qml.path = $$DESTPATH

view.setResizeMode(QQuickView::SizeRootObjectToView);
view.setSource(QUrl("qrc:///unit.qml"));

I will try it on Qt5.2.1 later.
Thanks again.

Hello, it looks like a bug to me. Would you mind posting your issue here:
"Bugreports":https://bugreports.qt-project.org/secure/Dashboard.jspa

Also could you please tell me if and which graphics card you're using?

haiying

Hello, the graphics card in my windows machine is Mobile Intel 4 Series Express Chipset Family.
And I will try to issue the bug later.
