详细描述

把鼠标事件委托给附加的 MouseHandler 对象。

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.

成员函数文档编制

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

构造新的 QMouseDevice instance with parent parent .

`[虚拟]` int QMouseDevice:: axisCount () const

重实现自 QAbstractPhysicalDevice::axisCount ().

Returns the axis count.

注意： Currently always returns 4.

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

重实现自 QAbstractPhysicalDevice::axisIdentifier ().

Convert axis name to axis identifier.

`[虚拟]` QStringList QMouseDevice:: axisNames () const

重实现自 QAbstractPhysicalDevice::axisNames ().

Returns the names of the axis.

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

`[虚拟]` int QMouseDevice:: buttonCount () const

重实现自 QAbstractPhysicalDevice::buttonCount ().

Returns the button count.

注意： Currently always returns 3.

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

重实现自 QAbstractPhysicalDevice::buttonIdentifier ().

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

`[虚拟]` QStringList QMouseDevice:: buttonNames () const

重实现自 QAbstractPhysicalDevice::buttonNames ().

Returns the names of the buttons.

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