特性文档编制

containsMouse : const bool

保持 true 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:

Qt3DInput::QMouseDevice * sourceDevice () const
void setSourceDevice (Qt3DInput::QMouseDevice * mouseDevice )

通知程序信号:

void sourceDeviceChanged (Qt3DInput::QMouseDevice * mouseDevice )
