Detailed Description

Qt 3D Studio presentation viewer settings.

Q3DSViewerSettings provides properties to define presentation independent viewer settings.

Note: This class should not be instantiated directly when working with the C++ APIs. Q3DSSurfaceViewer and Q3DSWidget create a Q3DSViewerSettings instance implicitly. This can be queried via Q3DSSurfaceViewer::settings() or Q3DSWidget::settings().

Member Type Documentation

enum Q3DSViewerSettings::ScaleMode

This enumeration specifies the possible scaling modes.

ConstantValueDescription
Q3DSViewerSettings::ScaleModeFit0Scales the presentation to fit the output area.
Q3DSViewerSettings::ScaleModeFill1Scales the presentation to completely fill the output area. This is the default.
Q3DSViewerSettings::ScaleModeCenter2Centers the presentation in the output area without scaling it.

enum Q3DSViewerSettings::ShadeMode

This enumeration specifies the possible shading modes.

ConstantValueDescription
Q3DSViewerSettings::ShadeModeShaded0The objects in the presentation are shaded normally.
Q3DSViewerSettings::ShadeModeShadedWireframe1The objects in the presentation are shaded with a super-imposed wireframe on top of the normal shading. Only objects that specify a tesselation mode will display this wireframe.

Note: As of Qt 3D Studio 2.0 the shade mode setting is ignored.

Property Documentation

matteColor : QColor

Specifies the matte color.

Access functions:

QColor matteColor() const
void setMatteColor(const QColor &color)

Notifier signal:

void matteColorChanged()

See also matteEnabled.

matteEnabled : bool

Specifies if the empty area around the presentation (applicable when scaleMode is set to ScaleModeCenter or ScaleModeFit) should be filled with a custom color.

The default value is false.

Access functions:

bool matteEnabled() const
void setMatteEnabled(bool isEnabled)

Notifier signal:

void matteEnabledChanged()

See also matteColor.

scaleMode : ScaleMode

Specifies the scaling mode. The default value is ScaleModeFill where the size of the presentation on-screen follows and fills the size of the output area (the window, the screen, or the area occupied by the Studio3D element).

During the design phase it can be valuable to see the presentation with some other scaling approach. For example, the Qt 3D Studio Viewer application uses ScaleModeCenter by default.

Access functions:

Q3DSViewerSettings::ScaleMode scaleMode() const
void setScaleMode(Q3DSViewerSettings::ScaleMode mode)

Notifier signal:

void scaleModeChanged()

shadeMode : ShadeMode

Note: This property is currently ignored.

Access functions:

Q3DSViewerSettings::ShadeMode shadeMode() const
void setShadeMode(Q3DSViewerSettings::ShadeMode mode)

Notifier signal:

void shadeModeChanged()

showRenderStats : bool

When this property is true, the interactive statistics and profile view is displayed in-scene, on top of the 3D content.

Note: This feature can be disabled at build time, in which case this property has no effect.

Default value is false.

Access functions:

bool isShowingRenderStats() const
void setShowRenderStats(bool show)

Notifier signal:

void showRenderStatsChanged()

Member Function Documentation

Q3DSViewerSettings::Q3DSViewerSettings(QObject *parent = nullptr)

Default constructs an instance of Q3DSViewerSettings.

[protected] Q3DSViewerSettings::Q3DSViewerSettings(Q3DSViewerSettingsPrivate &dd, QObject *parent)

Default constructs an instance of Q3DSViewerSettings.

[virtual] Q3DSViewerSettings::~Q3DSViewerSettings()

Destroys the instance of Q3DSViewerSettings. The destructor is virtual.

void Q3DSViewerSettings::load(const QString &group, const QString &organization = QString(), const QString &application = QString())

Loads previously saved viewer settings using group, organization and application.

Note: This function is not currently implemented.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

void Q3DSViewerSettings::save(const QString &group, const QString &organization = QString(), const QString &application = QString())

Persistently saves the viewer settings using group, organization and application.

Note: This function is not currently implemented.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.
