Detailed Description

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 , the paint() function is invoked and the resulting image is uploaded.

The QPaintedTextureImage must be attached to some QAbstractTexture .

setHeight()

PySide2.Qt3DRender.Qt3DRender.QPaintedTextureImage.heightChanged(w)

Parameters

w – int

PySide2.Qt3DRender.Qt3DRender.QPaintedTextureImage.paint(painter)

Parameters

painter – QPainter

Paints the texture image with the specified QPainter object painter .

PySide2.Qt3DRender.Qt3DRender.QPaintedTextureImage.setHeight(h)

Parameters

h – int

Sets the height (h ) of the texture image. Triggers an update, if the size changes.

height()

PySide2.Qt3DRender.Qt3DRender.QPaintedTextureImage.setSize(size)

Parameters

size – QSize

Sets the width and height of the texture image. Triggers an update, if the size changes.

size()

PySide2.Qt3DRender.Qt3DRender.QPaintedTextureImage.setWidth(w)

Parameters

w – int

Sets the width (w ) of the texture image. Triggers an update, if the size changes.

setSize()

PySide2.Qt3DRender.Qt3DRender.QPaintedTextureImage.sizeChanged(size)

Parameters

size – QSize

PySide2.Qt3DRender.Qt3DRender.QPaintedTextureImage.update([rect=QRect()])

Parameters

rect – QRect

Schedules the painted texture’s paint() function to be called, which in turn uploads the new image to the GPU. Parameter rect is currently unused.
