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 ) |
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 ) |
Constructs a new QMouseHandler instance with parent parent .
