Member Function Documentation

QTextureImage::QTextureImage(Qt3DCore::QNode *parent = nullptr)

Default constructs an instance of QTextureImage.

[protected] void QTextureImage::sceneChangeEvent(const Qt3DCore::QSceneChangePtr &change)

Sets the scene change event to change. change

[slot] void QTextureImage::setSource(const QUrl &source)

Sets the source url of the texture image to source.

Note: This triggers a call to update()

Sets the status to status. status

See also status().

QUrl QTextureImage::source() const

Returns the source url from which data for the texture image will be loaded.

Note: Getter function for property source.

See also setSource().

Status QTextureImage::status() const

Returns the current status.

Note: Getter function for property status.
