Detailed Description
The text, font, position, scaling, rotation, and colors of a custom label can be set. In addition, the visibility of the borders and background of the label can be toggled. Colors, borders, and background are determined by the active theme unless set explicitly.
Note: In scaling, the z-coordinate has no effect. Setting the same x- and y-coordinates retains the original font dimensions.
See also QAbstract3DGraph::addCustomItem().
Property Documentation
backgroundColor : QColor
This property holds the color for the label background, if enabled.
Defaults to Qt::gray.
Access functions:
| QColor | backgroundColor() const |
| void | setBackgroundColor(const QColor &color) |
Notifier signal:
| void | backgroundColorChanged(const QColor &color) |
See also backgroundEnabled.
backgroundEnabled : bool
This property holds whether the label background is enabled.
If set to false, backgroundColor() has no effect. Defaults to true.
Access functions:
| bool | isBackgroundEnabled() const |
| void | setBackgroundEnabled(bool enabled) |
Notifier signal:
| void | backgroundEnabledChanged(bool enabled) |
borderEnabled : bool
This property holds whether label borders are enabled.
Defaults to true.
Access functions:
| bool | isBorderEnabled() const |
| void | setBorderEnabled(bool enabled) |
Notifier signal:
| void | borderEnabledChanged(bool enabled) |
facingCamera : bool
This property holds whether the label will always face the camera.
Defaults to false. If set to true, rotation() has no effect.
Access functions:
| bool | isFacingCamera() const |
| void | setFacingCamera(bool enabled) |
Notifier signal:
| void | facingCameraChanged(bool enabled) |
font : QFont
This property holds the font to be used for the label.
Defaults to QFont("Arial", 20). Special formatting (for example, outlined) is not supported.
Access functions:
| QFont | font() const |
| void | setFont(const QFont &font) |
Notifier signal:
| void | fontChanged(const QFont &font) |
text : QString
This property holds the text for the label.
Rich text is not supported.
Access functions:
| QString | text() const |
| void | setText(const QString &text) |
Notifier signal:
| void | textChanged(const QString &text) |
textColor : QColor
This property holds the color for the label text.
Also affects the label border, if enabled. Defaults to Qt::white.
Access functions:
| QColor | textColor() const |
| void | setTextColor(const QColor &color) |
Notifier signal:
| void | textColorChanged(const QColor &color) |
See also borderEnabled.
Member Function Documentation
QCustom3DLabel::QCustom3DLabel(const QString &text, const QFont &font, const QVector3D &position, const QVector3D &scaling, const QQuaternion &rotation, QObject *parent = nullptr)
Constructs a custom 3D label with the given text, font, position, scaling, rotation, and optional parent.
Note: Setting the same x- and y-coordinates for scaling retains the original font dimensions.
QCustom3DLabel::QCustom3DLabel(QObject *parent = nullptr)
Constructs a custom 3D label with the given parent.
[virtual] QCustom3DLabel::~QCustom3DLabel()
Deletes the custom 3D label.
