详细描述

Provides a means of being notified about mouse events when attached to a QMouseDevice 实例。

注意： QMouseHandler components shouldn't be shared, not respecting that condition will most likely result in undefined behaviors.

特性文档编制

containsMouse : const bool

保持 true 若 QMouseHandler currently contains the mouse.

注意： In this context, contains mean that the ray originating from the mouse is intersecting with the Qt3DCore::QEntity that aggregates the current QMouseHandler instance component.

访问函数：

bool	containsMouse () const

通知程序信号：

void	containsMouseChanged (bool containsMouse )

sourceDevice : Qt3DInput::QMouseDevice *

Holds the current mouse source device of the QMouseHandler 实例。

访问函数：

QMouseDevice *	sourceDevice () const
void	setSourceDevice (QMouseDevice * mouseDevice )

通知程序信号：

void	sourceDeviceChanged (QMouseDevice * mouseDevice )
