Qt3DRender.QPaintedTextureImage ¶

概要 ¶

详细描述 ¶

A QPaintedTextureImage provides a way to specify a texture image (and thus an OpenGL texture) through a QPainter . The width and height of the texture image can be specified through the width and height or size properties.

A QPaintedTextureImage must be subclassed and the virtual paint() function implemented. Each time update() is called on the QPaintedTextureImage ， paint() function is invoked and the resulting image is uploaded.

QPaintedTextureImage must be attached to some QAbstractTexture .
