Synopsis

Functions

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 via createImageNode() or createImageNode() .

class 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

Filtering

Returns the filtering currently set on this texture node

setFiltering()

PySide2.QtQuick.QSGSimpleTextureNode.ownsTexture()
Return type

bool

Returns true if the node takes ownership of the texture; otherwise returns false .

setOwnsTexture()

PySide2.QtQuick.QSGSimpleTextureNode.rect()
Return type

QRectF

Returns the target rect of this texture node.

setRect()

PySide2.QtQuick.QSGSimpleTextureNode.setFiltering(filtering)
Parameters

filteringFiltering

Sets the filtering to be used for this texture node to filtering .

For smooth scaling, use Linear ; for normal scaling, use Nearest .

filtering()

PySide2.QtQuick.QSGSimpleTextureNode.setOwnsTexture(owns)
Parameters

ownsbool

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

rectQRectF

Sets the target rect of this texture node to r .

rect()

PySide2.QtQuick.QSGSimpleTextureNode.setRect(x, y, w, h)
Parameters
  • xqreal

  • yqreal

  • wqreal

  • hqreal

This is an overloaded function.

Sets the rectangle of this texture node to begin at (x , y ) and have width w and height h .

PySide2.QtQuick.QSGSimpleTextureNode.setSourceRect(r)
Parameters

rQRectF

Sets the source rect of this texture node to r .

See also

sourceRect()

PySide2.QtQuick.QSGSimpleTextureNode.setSourceRect(x, y, w, h)
Parameters
  • xqreal

  • yqreal

  • wqreal

  • hqreal

This is an overloaded function.

Sets the rectangle of this texture node to show its texture from (x , y ) and have width w and height h relatively to the textureSize .

PySide2.QtQuick.QSGSimpleTextureNode.setTexture(texture)
Parameters

textureQSGTexture

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.

texture()

PySide2.QtQuick.QSGSimpleTextureNode.setTextureCoordinatesTransform(mode)
Parameters

modeTextureCoordinatesTransformMode

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.

PySide2.QtQuick.QSGSimpleTextureNode.sourceRect()
Return type

QRectF

Returns the source rect of this texture node.

See also

setSourceRect()

PySide2.QtQuick.QSGSimpleTextureNode.texture()
Return type

QSGTexture

Returns the texture for this texture node

See also

setTexture()

PySide2.QtQuick.QSGSimpleTextureNode.textureCoordinatesTransform()
Return type

TextureCoordinatesTransformMode

Returns the mode used to generate texture coordinates for this node.
