It’s not impossible to put text into the scenegraph from C++, but you will need to use private APIs, so you will be tied to a range of Qt versions where those private APIs don’t change. You can use QTextLayout to generate QGlyphRuns, and create a QSGGlyphNode for each. Some other QSG stuff is public (and there are examples in qtdeclarative/examples/quick/scenegraph), but QSGGlyphNode isn't. It may turn out that rendering textures with QPainter, as you suggest, is faster anyway. _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
