Detailed Description

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

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

Property Documentation

extrusionLength : float

Holds the extrusion length of the text.

Access functions:

float extrusionLength() const
void setDepth(float extrusionLength)

Notifier signal:

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.

Access functions:

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

Notifier signal:

void fontChanged(const QFont &font)

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

Holds the geometry index attribute.

Access functions:

Qt3DCore::QAttribute *indexAttribute() const

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

Holds the geometry normal attribute.

Access functions:

Qt3DCore::QAttribute *normalAttribute() const

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

Holds the geometry position attribute.

Access functions:

Qt3DCore::QAttribute *positionAttribute() const

text : QString

Holds the text used for the mesh.

Access functions:

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

Notifier signal:

void textChanged(const QString &text)
