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 .

class PySide6.Qt3DRender.Qt3DRender.QPaintedTextureImage([parent=None])#

Parameters:: parent – PySide6.Qt3DCore.Qt3DCore.QNode

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property PᅟySide6.Qt3DRender.Qt3DRender.QPaintedTextureImage.height: int#

This property holds the height of the texture image. The height must be greater than or equal to 1.

Access functions:

height ()
setHeight (h)
Signal heightChanged (w)

property PᅟySide6.Qt3DRender.Qt3DRender.QPaintedTextureImage.size: PySide6.QtCore.QSize#

This property holds the size of the texture image.

height width

Access functions:

size ()
setSize (size)
Signal sizeChanged (size)

property PᅟySide6.Qt3DRender.Qt3DRender.QPaintedTextureImage.width: int#

This property holds the width of the texture image. The width must be greater than or equal to 1.

Access functions:

width ()
setWidth (w)
Signal widthChanged (w)

PySide6.Qt3DRender.Qt3DRender.QPaintedTextureImage.height()#

Return type:: int

See also

setHeight()

Getter of property height .

PySide6.Qt3DRender.Qt3DRender.QPaintedTextureImage.heightChanged(w)#

Parameters:: w – int

Notification signal of property height .

abstract PySide6.Qt3DRender.Qt3DRender.QPaintedTextureImage.paint(painter)#

Parameters:: painter – PySide6.QtGui.QPainter

Paints the texture image with the specified QPainter object painter.

QPainter considers the top-left corner of an image as its origin, while OpenGL considers the bottom-left corner of a texture as its origin. An easy way to account for this difference is to set a custom viewport on the painter before doing any other painting:

painter->setViewport(0, height(), width(), -height());
...

PySide6.Qt3DRender.Qt3DRender.QPaintedTextureImage.setHeight(h)#

Parameters:: h – int

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

See also

height()

Setter of property height .

PySide6.Qt3DRender.Qt3DRender.QPaintedTextureImage.setSize(size)#

Parameters:: size – PySide6.QtCore.QSize

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

See also

size()

Setter of property size .

PySide6.Qt3DRender.Qt3DRender.QPaintedTextureImage.setWidth(w)#

Parameters:: w – int

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

See also

width()

Setter of property width .

PySide6.Qt3DRender.Qt3DRender.QPaintedTextureImage.size()#

Return type:: PySide6.QtCore.QSize
