Detailed Description¶
A
QPaintedTextureImage
provides a way to specify a texture image (and thus an OpenGL texture) through aQPainter
. 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 virtualpaint()
function implemented. Each timeupdate()
is called on theQPaintedTextureImage
, thepaint()
function is invoked and the resulting image is uploaded.The
QPaintedTextureImage
must be attached to someQAbstractTexture
.
