详细描述

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.

注意： In scaling, the z-coordinate has no effect. Setting the same x- and y-coordinates retains the original font dimensions.

backgroundColor : QColor

This property holds the color for the label background, if enabled.

默认为 Qt::gray .

访问函数：

QColor	backgroundColor () const
void	setBackgroundColor (QColor color )

通知程序信号：

void	backgroundColorChanged (QColor color )

另请参阅 backgroundVisible .

backgroundVisible : bool

This property holds whether the label background is visible.

若设为 false , backgroundColor () 不起作用。默认为 true .

访问函数：

bool	isBackgroundVisible () const
void	setBackgroundVisible (bool visible )

通知程序信号：

void	backgroundVisibleChanged (bool visible )

borderVisible : bool

This property holds whether label borders are visible.

默认为 true .

访问函数：

bool	isBorderVisible () const
void	setBorderVisible (bool visible )

通知程序信号：

void	borderVisibleChanged (bool visible )

facingCamera : bool

This property holds whether the label will always face the camera.

默认为 false 。若设为 true , rotation () has no effect.

访问函数：

bool	isFacingCamera () const
void	setFacingCamera (bool enabled )

通知程序信号：

void	facingCameraChanged (bool enabled )

font : QFont

This property holds the font to be used for the label.

默认为 QFont("Arial", 20) . Special formatting (for example, outlined) is not supported.

访问函数：

QFont	font () const
void	setFont (const QFont & font )

通知程序信号：

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 )

通知程序信号：

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 (QColor color )

通知程序信号：

void	textColorChanged (QColor color )

另请参阅 borderVisible .

成员函数文档编制

[explicit] QCustom3DLabel:: QCustom3DLabel ( QObject * parent = nullptr)

Constructs a custom 3D label with the given parent .

[explicit] QCustom3DLabel:: QCustom3DLabel (const QString & text , const QFont & font , QVector3D position , QVector3D scaling , const QQuaternion & rotation , QObject * parent = nullptr)

Constructs a custom 3D label with the given text , font , position , scaling , rotation , and optional parent .

注意： Setting the same x- and y-coordinates for scaling retains the original font dimensions.

[override virtual noexcept] QCustom3DLabel:: ~QCustom3DLabel ()

Deletes the custom 3D label.
