The brush style is set to the corresponding gradient style (either Qt::LinearGradientPattern, Qt::RadialGradientPattern or Qt::ConicalGradientPattern). This should work similar to filling a QBrush with a texture by using QBrush. The default position of an item is always at 0, 0 (related to its parent, and based on the Graphics View Coordinate System), meaning that if you create a QGraphicsRectItem(100, 100, 200, 200) its position will be 0, 0 and its rectangle will be shown Your approach is much more complex than it needs, and there are various issues about it (some of them quite important).

To make this easy to demonstrate we'll be using the following stub application which handles creating our container (a QLabel), creating a pixmap canvas, displaying that in the Python QGraphicsScene. Alternatively, you can specify a QColor instead of a QBrush; the QBrush constructor (taking a QColor argument) will automatically create a solid pattern brush. Bitmap drawing operations in Qt are handled through the QPainter class. We always welcome contributions to the snippet translation. , a position and a color.
