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 )

indexAttribute : Qt3DRender::QAttribute * const

Holds the geometry index attribute.

访问函数:

Qt3DRender::QAttribute * indexAttribute () const

normalAttribute : Qt3DRender::QAttribute * const

Holds the geometry normal attribute.

访问函数:

Qt3DRender::QAttribute * normalAttribute () const

positionAttribute : Qt3DRender::QAttribute * const

Holds the geometry position attribute.

访问函数:

Qt3DRender::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 )
