QSGSimpleTextureNode ¶

概要 ¶

详细描述 ¶

警告

The simple texture node class must have a texture before being added to the scene graph to be rendered.

警告

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 凭借 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.

常量	描述
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. ownsTexture ( ) ¶

返回类型

bool

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

PySide2.QtQuick.QSGSimpleTextureNode. rect ( ) ¶

返回类型

QRectF

Returns the target rect of this texture node.

PySide2.QtQuick.QSGSimpleTextureNode. setFiltering ( filtering ) ¶

参数

filtering – 过滤

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

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

PySide2.QtQuick.QSGSimpleTextureNode. setOwnsTexture ( owns ) ¶

参数

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 ) ¶

参数

rect – QRectF

Sets the target rect of this texture node to r .

rect()

PySide2.QtQuick.QSGSimpleTextureNode. setRect ( x , y , w , h ) ¶

参数

• x – qreal

• y – qreal

• w – qreal

• h – qreal

这是重载函数。

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

PySide2.QtQuick.QSGSimpleTextureNode. setSourceRect ( r ) ¶

参数

r – QRectF

Sets the source rect of this texture node to r .

sourceRect()

PySide2.QtQuick.QSGSimpleTextureNode. setSourceRect ( x , y , w , h ) ¶

参数

• x – qreal

• y – qreal

• w – qreal

• h – qreal

这是重载函数。

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 ) ¶

参数

texture – QSGTexture

Sets the texture of this texture node to texture .

使用 setOwnsTexture() to set whether the node should take ownership of the texture. By default, the node does not take ownership.

警告

A texture node must have a texture before being added to the scenegraph to be rendered.

PySide2.QtQuick.QSGSimpleTextureNode. setTextureCoordinatesTransform ( mode ) ¶

参数

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.
