詳細描述

A QMouseDevice delegates mouse events from physical mouse device to QMouseHandler objects. The sensitivity of the mouse can be controlled with the QMouseDevice::sensitivity property, which specifies the rate in which the logical mouse coordinates change in response to physical movement of the mouse.

sensitivity : float

Holds the sensitivity of the mouse device. The default is 0.1.

訪問函數：

float	sensitivity () const
void	setSensitivity (float value )

通知程序信號：

void	sensitivityChanged (float value )

updateAxesContinuously : bool

若 true , axes will be updated anytime they change regardless of whether any mouse button is being pressed. Otherwise, axes are updated only when one of the mouse buttons is being pressed.

默認值為 false .

該特性在 Qt 5.15 引入。

QMouseDevice:: QMouseDevice ( Qt3DCore::QNode * parent = nullptr)

Constructs a new QMouseDevice instance with parent parent .

`[override virtual]` int QMouseDevice:: axisCount () const

重實現： QAbstractPhysicalDevice::axisCount () const.

Returns the axis count.

注意： Currently always returns 4.

`[override virtual]` int QMouseDevice:: axisIdentifier (const QString & name ) const

重實現： QAbstractPhysicalDevice::axisIdentifier (const QString &name) const.

Convert axis name to axis identifier.

`[override virtual]` QStringList QMouseDevice:: axisNames () const

重實現： QAbstractPhysicalDevice::axisNames () const.

Returns the names of the axis.

注意： Currently always returns StringList["X", "Y"]

`[override virtual]` int QMouseDevice:: buttonCount () const

重實現： QAbstractPhysicalDevice::buttonCount () const.

Returns the button count.

注意： Currently always returns 3.

`[override virtual]` int QMouseDevice:: buttonIdentifier (const QString & name ) const

重實現： QAbstractPhysicalDevice::buttonIdentifier (const QString &name) const.

Returns the button identifier that corresponds with the specified name . The possible return values are documented in QMouseEvent::Buttons .

`[override virtual]` QStringList QMouseDevice:: buttonNames () const

重實現： QAbstractPhysicalDevice::buttonNames () const.

Returns the names of the buttons.

注意： Currently always returns StringList["Left", "Right", "Center"]
