詳細描述

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.

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

另請參閱 QAbstract3DGraph::addCustomItem ().

backgroundColor : QColor

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

默認為 Qt::gray .

訪問函數：

QColor	backgroundColor () const
void	setBackgroundColor (const QColor & color )

通知程序信號：

void	backgroundColorChanged (const QColor & color )

另請參閱 backgroundEnabled .

backgroundEnabled : bool

此特性保持是否啓用標簽背景。

若設為 false , backgroundColor () 不起作用。默認為 true .

訪問函數：

bool	isBackgroundEnabled () const
void	setBackgroundEnabled (bool enabled )

通知程序信號：

void	backgroundEnabledChanged (bool enabled )

borderEnabled : bool

This property holds whether label borders are enabled.

默認為 true .

訪問函數：

bool	isBorderEnabled () const
void	setBorderEnabled (bool enabled )

通知程序信號：

void	borderEnabledChanged (bool enabled )

facingCamera : bool

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

默認為 false 。若設為 true , rotation () has no effect.

訪問函數：

bool	isFacingCamera () const
void	setFacingCamera (bool enabled )

通知程序信號：

void	facingCameraChanged (bool enabled )

font : QFont

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

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

訪問函數：

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

通知程序信號：

void	fontChanged (const QFont & font )

text : QString

This property holds the text for the label.

Rich text is not supported.

訪問函數：

QString	text () const
void	setText (const QString & text )

通知程序信號：

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 .

訪問函數：

QColor	textColor () const
void	setTextColor (const QColor & color )

通知程序信號：

void	textColorChanged (const QColor & color )

另請參閱 borderEnabled .

QCustom3DLabel:: QCustom3DLabel ( QObject * parent = 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 = 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.

[虛擬] QCustom3DLabel:: ~QCustom3DLabel ()

Deletes the custom 3D label.
