## Member Function Documentation

### QKeyboardDevice::QKeyboardDevice(Qt3DCore::QNode *parent = nullptr)

Constructs a new QKeyboardDevice instance with parent.

### `[virtual]` int QKeyboardDevice::axisCount() const

Reimplemented from QAbstractPhysicalDevice::axisCount().

Returns the axis count.

Note: Currently always returns zero.

### `[virtual]` int QKeyboardDevice::axisIdentifier(const QString &name) const

Reimplemented from QAbstractPhysicalDevice::axisIdentifier().

Returns the axisIdentifier matching the name.

### `[virtual]` QStringList QKeyboardDevice::axisNames() const

Reimplemented from QAbstractPhysicalDevice::axisNames().

Returns the axis names.

Note: Currently always returns empty QStringList.

### `[virtual]` int QKeyboardDevice::buttonCount() const

Reimplemented from QAbstractPhysicalDevice::buttonCount().

Returns the button count.

### `[virtual]` int QKeyboardDevice::buttonIdentifier(const QString &name) const

Reimplemented from QAbstractPhysicalDevice::buttonIdentifier().

Returns the buttonIdentifier matching the name.

### `[virtual]` QStringList QKeyboardDevice::buttonNames() const

Reimplemented from QAbstractPhysicalDevice::buttonNames().

Returns the button names.
