Detailed Description¶
Warning
The simple texture node class must have a texture before being added to the scene graph to be rendered.
Warning
This utility class is only functional when running with the default or software backends of the Qt Quick scenegraph. As an alternative, prefer using
QSGImageNode
viacreateImageNode()
orcreateImageNode()
.
- class PySide2.QtQuick.QSGSimpleTextureNode¶
Constructs a new simple texture node
- PySide2.QtQuick.QSGSimpleTextureNode.TextureCoordinatesTransformFlag¶
The enum is used to specify the mode used to generate texture coordinates for a textured quad.
Constant
Description
QSGSimpleTextureNode.NoTransform
Texture coordinates are oriented with window coordinates i.e. with origin at top-left.
QSGSimpleTextureNode.MirrorHorizontally
Texture coordinates are inverted in the horizontal axis with respect to window coordinates
QSGSimpleTextureNode.MirrorVertically
Texture coordinates are inverted in the vertical axis with respect to window coordinates
- PySide2.QtQuick.QSGSimpleTextureNode.filtering()¶
- Return type:
Returns the filtering currently set on this texture node
See also
- PySide2.QtQuick.QSGSimpleTextureNode.ownsTexture()¶
- Return type:
bool
Returns
true
if the node takes ownership of the texture; otherwise returnsfalse
.See also
- PySide2.QtQuick.QSGSimpleTextureNode.rect()¶
- Return type:
Returns the target rect of this texture node.
See also
- PySide2.QtQuick.QSGSimpleTextureNode.setFiltering(filtering)¶
- Parameters:
filtering –
Filtering
Sets the filtering to be used for this texture node to
filtering
.For smooth scaling, use
Linear
; for normal scaling, useNearest
.See also
- PySide2.QtQuick.QSGSimpleTextureNode.setOwnsTexture(owns)¶
- Parameters:
owns – bool
Sets whether the node takes ownership of the texture to
owns
.By default, the node does not take ownership of the texture.

- PySide2.QtQuick.QSGSimpleTextureNode.setRect(rect)¶
- Parameters:
rect –
PySide2.QtCore.QRectF
Sets the target rect of this texture node to
r
.See also
- PySide2.QtQuick.QSGSimpleTextureNode.setRect(x, y, w, h)
- Parameters:
x – float
y – float
w – float
h – float
This is an overloaded function.
Sets the rectangle of this texture node to begin at (
x
,y
) and have widthw
and heighth
.
- PySide2.QtQuick.QSGSimpleTextureNode.setSourceRect(r)¶
- Parameters:
Sets the source rect of this texture node to
r
.See also
- PySide2.QtQuick.QSGSimpleTextureNode.setSourceRect(x, y, w, h)
- Parameters:
x – float
y – float
w – float
h – float
This is an overloaded function.
Sets the rectangle of this texture node to show its texture from (
x
,y
) and have widthw
and heighth
relatively to thetextureSize
.
- PySide2.QtQuick.QSGSimpleTextureNode.setTexture(texture)¶
- Parameters:
texture –
PySide2.QtQuick.QSGTexture
Sets the texture of this texture node to
texture
.Use
setOwnsTexture()
to set whether the node should take ownership of the texture. By default, the node does not take ownership.Warning
A texture node must have a texture before being added to the scenegraph to be rendered.

- PySide2.QtQuick.QSGSimpleTextureNode.setTextureCoordinatesTransform(mode)¶
- Parameters:
mode –
TextureCoordinatesTransformMode
Sets the method used to generate texture coordinates to
mode
. This can be used to obtain correct orientation of the texture. This is commonly needed when using a third party OpenGL library to render to texture as OpenGL has an inverted y-axis relative to Qt Quick.See also
- PySide2.QtQuick.QSGSimpleTextureNode.sourceRect()¶
- Return type:
Returns the source rect of this texture node.
See also
- PySide2.QtQuick.QSGSimpleTextureNode.texture()¶
- Return type:
Returns the texture for this texture node
See also
- PySide2.QtQuick.QSGSimpleTextureNode.textureCoordinatesTransform()¶
- Return type:
TextureCoordinatesTransformMode
Returns the mode used to generate texture coordinates for this node.
