resize issues when rendering specific region of QWebFrame

[jkelly_]

Hi,

I want to render a specific part of a web page when using the QWebView widget. I've created a subclass of QWebView and I've overridden the paintEvent method. The code for the paintEvent method is below:

void MyWidget::paintEvent(QPaintEvent *ev)
{
	if (!page())
		return;
 
	QPainter p(this);
	// specify the region we want to paint
	QRegion region(QRect(1, 1, 587, 483)); // x, y, width, height
 
	QWebFrame *frame = page()->mainFrame();
	frame->render(&p, region);
}

void MyWidget::paintEvent(QPaintEvent *ev)
{
	if (!page())
		return;

	QPainter p(this);
	// specify the region we want to paint
	QRegion region(QRect(1, 1, 587, 483)); // x, y, width, height

	QWebFrame *frame = page()->mainFrame();
	frame->render(&p, region);
}

To copy to clipboard, switch view to plain text mode 

The only problem i have is that when i resize the window that contains my subclass of QWebView then i get visual artifacts. Is there something i should do after i call frame->render()?
