详细描述
The QCustom3DLabel class adds a custom label to a graph.
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.
参见 QAbstract3DGraph::addCustomItem().
属性
backgroundColor : QColor
This property holds the color for the label background, if enabled.
Defaults to Qt::gray.
访问函数:
| QColor | backgroundColor() const |
| void | setBackgroundColor(const QColor &color) |
Notifier signal:
| void | backgroundColorChanged(const QColor &color) |
backgroundEnabled : bool
This property holds whether the label background is enabled.
If set to false, backgroundColor() has no effect. Defaults to true.
访问函数:
| 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.
访问函数:
| 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.
访问函数:
| 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.
访问函数:
| 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.
访问函数:
| 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.
访问函数:
| QColor | textColor() const |
| void | setTextColor(const QColor &color) |
Notifier signal:
| void | textColorChanged(const QColor &color) |
参见 borderEnabled.
成员函数
QCustom3DLabel::QCustom3DLabel(QObject *parent = Q_NULLPTR)
Constructs a custom 3D label with the given parent.
QCustom3DLabel::QCustom3DLabel(const QString &text, const QFont &font, const QVector3D &position, const QVector3D &scaling, const QQuaternion &rotation, QObject *parent = Q_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.
[virtual] QCustom3DLabel::~QCustom3DLabel()
Deletes the custom 3D label.
