QWidgets and QPixmaps and Stylesheets .... oh my.

[steb]

using QT4.5, I have a class derived from QWidget. It uses stylesheets to loads a bitmap into the background. This stylesheet is loaded at runtime and is user made.

class MyClass : public QWidget
	Q_OBJECT
public:
	MyClass (QWidget *pParent )  : QWidget( pParent) {}
	~MyClass () {}
	virtual void paintEvent(QPaintEvent *ev);
};

class MyClass : public QWidget
	Q_OBJECT
public:
	MyClass (QWidget *pParent )  : QWidget( pParent) {}
	~MyClass () {}
	virtual void paintEvent(QPaintEvent *ev);
};

To copy to clipboard, switch view to plain text mode 

ex from a stylesheet file:

MyClass  {
  background-image:	url(images/background.png);
}

MyClass  {
  background-image:	url(images/background.png);
}

To copy to clipboard, switch view to plain text mode 

in my app, I load the stylesheet as runtime using something like:

QFile file( "thesheet.qss" );
	file.open( QFile::ReadOnly );
	QString styleSheet = QLatin1String( file.readAll() );
	qApp->setStyleSheet(styleSheet);

QFile file( "thesheet.qss" );
	file.open( QFile::ReadOnly );
	QString styleSheet = QLatin1String( file.readAll() );
	qApp->setStyleSheet(styleSheet);

The background loads fine from the stylesheet....

But in my MyClass paintEvent() code, I want to be able to access the QPixmap that the base QWidget class creates for the background (... but it seems that QWidget doesn't provide any accessors.).

I know I can pre-parse the stylesheet to find the image filename, or I could use an inelegant hack and render the widget to a Painter using:

QPainter_end(Painter);
QPixmap_grabWidget(Widget);
QPainter_begin(Painter);

QPainter_end(Painter);
QPixmap_grabWidget(Widget);
QPainter_begin(Painter);

but isn't there a simple way to access the background image?
