◆ preprocess()

void QSGSoftwareInternalImageNode::preprocess ( )
overridevirtual

Override this function to do processing on the node before it is rendered.

Preprocessing needs to be explicitly enabled by setting the flag QSGNode::UsePreprocess. The flag needs to be set before the node is added to the scene graph and will cause the preprocess() function to be called for every frame the node is rendered.

Warning
Beware of deleting nodes while they are being preprocessed. It is possible, with a small performance hit, to delete a single node during its own preprocess call. Deleting a subtree which has nodes that also use preprocessing may result in a segmentation fault. This is done for performance reasons.

Reimplemented from QSGNode.
