Detailed Description
Encapsulates the necessary information to create an OpenGL texture image from an image source.
It contains the necessary information mipmap level, layer, cube face and source URL to load at the proper place data into an OpenGL texture.
Member Type Documentation
enum QTextureImage::Status
This enumeration specifies the status values for texture image loading.
| Constant | Value | Description |
|---|---|---|
Qt3DRender::QTextureImage::None | 0 | The texture image loading has not been started yet. |
Qt3DRender::QTextureImage::Loading | 1 | The texture image loading has started, but not finised. |
Qt3DRender::QTextureImage::Ready | 2 | The texture image loading has finished. |
Qt3DRender::QTextureImage::Error | 3 | The texture image loading confronted an error. |

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()
Note: Setter function for property source.
See also source().
[protected] void QTextureImage::setStatus(Status status)
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.
See also setStatus().
