问题 I am trying to load a simple cube with per-vertex color information from a Stanford PLY file using QML. My entity looks like this: Entity { id: circle property Material materialPoint: Material { effect: Effect { techniques: Technique { renderPasses: RenderPass { shaderProgram: ShaderProgram { vertexShaderCode: loadSource("qrc:/imports/org/aid/shared/geometry/shaders/point.vert") fragmentShaderCode: loadSource("qrc:/imports/org/aid/shared/geometry/shaders/point.frag") } } } } parameters:

问题 I am trying to create a new QML type by using Python, but I am having trouble with registering a QML type. However, I am getting an Error: TypeError: 'PySide2.QtQml.qmlRegisterType' called with wrong argument types: PySide2.QtQml.qmlRegisterType(module, str, int, int, str) Supported signatures: PySide2.QtQml.qmlRegisterType(type, str, int, int, str) So I understand that its expecting a type, however, in this blogpost it does something similar: qmlRegisterType(PieChart, 'Charts', 1, 0,

问题 I have a minesweeper-style game developed as a way of practicing QML. The issue I have is on the memory usage which grows quickly out of hands (>700 Mb) depending on the size of the grid. I made it sizeable up to 150*150 (bigger grid leads to crash as it's win32). The grid is built like this (with bits from Expose 2D C++ Game Board to QML using QAbstractItemModel) (the image is used to show a "bomb.png", the text to show the number of mines) : Flickable { id: flickable width: parent.width

问题 I have the following code: if __name__ == '__main__': os.environ["QT_QUICK_CONTROLS_STYLE"] = "Material" app = QGuiApplication(sys.argv) engine = QQmlApplicationEngine() engine.load('./QML/main.qml') if not engine.rootObjects(): sys.exit(-1) sys.exit(app.exec_()) As you can see, if `engine.load' fails all I'll see is a '-1' exit code, without any elaboration on why it failed and what the error happened. How can I print the QML error in the python console? There was a walkaround for this with
