Chaining painting to images [SOLVED]
Maybe this post is another forum, but anyway it's related to QML.
I have this type of problem:
@void MyDeclarativeItem::paint(QPainter *painter, const QStyleOptionGraphicsItem *, QWidget *)
//draw something to image
Which of course fails, with error when construncting painterToImage 'QPainter::begin: A paint device can only be painted by one painter at a time.'.
Someone knows how to paint to image, and then that painted image to be used in painter of the QDeclarativeItem? Or am I missing something?
The code you show looks alright to me.
Then why I am getting the error?
Based on the tiny sample of code you posted, that is impossible to tell. Perhaps there is another painter still open on the image somehow?
Well, it doesn't depend if I paint or not in paint() method. Which is more strange.
All I have done is this
@m_myImage = QImage(w, h, QImage::Format_ARGB32_Premutliplied);
Nothing more. And I am still getting the same error.
