LEAK: CachedResource XMLHttpRequest WebCoreNode?

dongdong

Hi,

I created a QtWebkit application following the steps in "this article":http://blog.lagentz.com/general/how-to-compile-and-build-a-qtwebkit-application-with-ms-visual-studio-2008/.
when run it in visual studio,
F5 -> click the window(web page) ->close the window
I found there is
LEAK: 12 CachedResource
LEAK: 1 XMLHttpRequest
LEAK: 337 WebCoreNode
in output window

what's wrong?
Is that meaning there are memory leak?

I'm using visual stdio 2005 + qt-everywhere-opensource-src-4.8.0

I am having a very similar issue only my application does not use QtWebkit. I am instantiating a QDeclarativeView and setting it as the central widget of a QMainWindow object. Prior to the call to setCentralWidget(...) I call setSource() on the view and pass it my QML file. The error I get on the VS console when I close the application is LEAK: 228 Structure.

I am using Visual Studio 2008 and the pre-built Visual Studio 2008 Qt 4.8.0 libraries.

What does a LEAK report like this mean? Is it truly a memory leak to be resolved? Why is it not reported in the same fashion as other memory leaks in Visual Studio?

Thanks in advance for any responses.

Any more insight into this? We started getting this message too, and I'm not even sure where it comes from - Qt, Visual Studio, radio transmissions from outer space...?

I've got the same log output using MinGW on Windows 7.
No idea where it comes from too.

I too see the same thing, Visual Studio 2012 on Win8.1 and Qt5.3

LEAK: 376 CachedResource
LEAK: 6 XMLHttpRequest
LEAK: 2462 WebCoreNode

If I comment out my call to QWebView::load(..) then the CachedResource and XMLHttpRequest leaks go away, but WebCoreNode remains.
