详细描述

The QExtrudedTextGeometry class is most commonly used internally by the QText3DMesh but can also be used in custom Qt3DRender::QGeometryRenderer 子类。

The origin of the geometry is the rear left end of the text's baseline.

特性文档编制

extrusionLength : float

Holds the extrusion length of the text.

访问函数：

float	extrusionLength () const
void	setDepth (float extrusionLength )

通知程序信号：

void	depthChanged (float extrusionLength )

font : QFont

Holds the font of the text.

The geometry is normalized by the font's pointSize, so a larger pointSize will result in smoother, rather than larger, text. pixelSize should not be used.

访问函数：

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

通知程序信号：

void	fontChanged (const QFont & font )

[read-only] indexAttribute : Qt3DCore::QAttribute * const

Holds the geometry index attribute.

访问函数：

Qt3DCore::QAttribute *

indexAttribute () const

[read-only] normalAttribute : Qt3DCore::QAttribute * const

Holds the geometry normal attribute.

访问函数：

Qt3DCore::QAttribute *

normalAttribute () const

[read-only] positionAttribute : Qt3DCore::QAttribute * const

Holds the geometry position attribute.

访问函数：

Qt3DCore::QAttribute *

positionAttribute () const

text : QString

Holds the text used for the mesh.

访问函数：

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

通知程序信号：

void	textChanged (const QString & text )
