Hi,
I want to render one page after loading its all elements. Now, the qtwebkit
download
the elements while rendering, I want to change this behavior. In my
application,
I have qt4.8+directfb, and all data include webpage will be rendered by
directfb plugin of
qt to directfb. And I tried to receive the loadStarted and loadFinished
signal of mainframe,
and disable flip window surface to screen when receive loadStarted signal,
and enable flip
window surface to screen when receive loadFinished. The detail as follows:
connect(mainframe, SIGNAL(loadStarted()), this, SLOT(slotLoadStarted()));
connect(mainframe, SIGNAL(loadFinished()), this, SLOT(slotLoadFinished()));
void slotLoadStarted()
{
//disable rendering in qtdirectfb level
disableDfbRender();
}
void slotLoadFinished()
{
// enable rendering in qtdirectfb level
// and refresh whole window surface
enableDfbRender();
refreshDfbWindow();
}
But this solution is not successful, because the loadFinished signal is not
means all elements
have been drawed to the window surface, so refresh window surface to
primary surface only push
part data to screen.
So how can I render whole webpage after loading all its elements. Does
qtwebkit provide the API or
signal? Or how can I modified the source code of qtwebkit to reach this
goal?
I don't know if it's proper to ask question here. But I read the qtwebkit
code and at last I don't find how to
achieve this goal.
