## 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)

## Member Function Documentation

### `[explicit]` QExtrudedTextGeometry::QExtrudedTextGeometry(Qt3DCore::QNode *parent = nullptr)

Constructs a new QExtrudedTextGeometry with parent.
