Detailed Description
Displays a Qt 3D Studio presentation on a widget.
Q3DSWidget is used to specify a render widget for Qt 3D Studio presentation.
Example Usage
Q3DSWidget viewer; viewer.presentation()->setSource(QUrl(QStringLiteral("qrc:/my_presentation.uip"))); viewer.setUpdateInterval(0); viewer.settings()->setScaleMode(Q3DSViewerSettings::ScaleModeFill); viewer.settings()->setShowRenderStats(true); // Register a scene element object for slide management (optional) Q3DSSceneElement scene(viewer.presentation(), QStringLiteral("Scene")); // Register an element object for attribute setting (optional) Q3DSElement element(viewer.presentation(), QStringLiteral("Scene.Layer.myLabel")); viewer.initialize();
See also Q3DSSurfaceViewer.
Property Documentation
running : const bool
The value of this property is true
when the viewer has been initialized and the presentation is running.
This property is read-only.
Access functions:
bool | isRunning() const |
Notifier signal:
void | runningChanged(bool initialized) |
updateInterval : int
Holds the viewer update interval in milliseconds. If the value is negative, the viewer doesn't update the presentation automatically.
The default value is -1.
Access functions:
int | updateInterval() const |
void | setUpdateInterval(int interval) |
Notifier signal:
void | updateIntervalChanged(bool autoUpdate) |
See also QWidget::update().
Member Function Documentation
Q3DSWidget::Q3DSWidget(QWidget *parent = nullptr)
Default constructs an instance of Q3DSWidget.
[virtual]
Q3DSWidget::~Q3DSWidget()
Destroys the instance of Q3DSWidget. The destructor is virtual.
bool Q3DSWidget::initialize()
Initializes Q3DSWidget to render the presentation.
The source property of the attached presentation must be set before the viewer can be initialized.
Returns whether the initialization succeeded.
See also running, Q3DSPresentation::source, and presentation().
