how to clear memory in QWebView ?

[tiaoweiliao]

i use QWebView , call evaluateJavaScript() insert content to Web page. memory increasing .

I want to achieve "clear" function. free memory.

How did this?

i try call QWebSettings::globalSettings()->clearMemoryCaches(); and reload new Empty page.

but i open Task Manager , memory usage no change.

i use Qt 5.3.1 mingw , win7 64bit.

That doesn't really matter, the operating system might not have reclaimed the memory, etc.
Does the memory usage increase when you add again after loading an empty page?

when I add again after loading an empty page , memory not reduce.
Task manager shows programs use a lot of memory , this is not good.
Please excuse my english

I asked if it increases immediately again.
If it does not, then the memory is just not reclaimed but reused.
