詳細描述

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

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

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.

訪問函數：

bool	containsMouse () const

通知程序信號：

void	containsMouseChanged (bool containsMouse )

sourceDevice : Qt3DInput::QMouseDevice *

Holds the current mouse source device of the QMouseHandler 實例。

訪問函數：

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

通知程序信號：

void	sourceDeviceChanged (Qt3DInput::QMouseDevice * mouseDevice )

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

構造新的 QMouseHandler instance with parent parent .

[虛擬] QMouseHandler:: ~QMouseHandler ()

Destroys the instance of QMouseHandler. The destructor is virtual.

[signal] void QMouseHandler:: clicked ( Qt3DInput::QMouseEvent * mouse )

This signal is emitted when a mouse button is clicked with the event details being contained within mouse

[signal] void QMouseHandler:: doubleClicked ( Qt3DInput::QMouseEvent * mouse )

This signal is emitted when a mouse button is double clicked with the event details being contained within mouse

[signal] void QMouseHandler:: entered ()

[signal] void QMouseHandler:: exited ()

[signal] void QMouseHandler:: positionChanged ( Qt3DInput::QMouseEvent * mouse )

This signal is emitted when the mouse position changes with the event details being contained within mouse

[signal] void QMouseHandler:: pressAndHold ( Qt3DInput::QMouseEvent * mouse )

This signal is emitted when a mouse button is pressed and held down with the event details being contained within mouse
