Constructor Detail

MouseInputHandler

public MouseInputHandler(Component source,
                         Component destination,
                         MouseEvent event)

Constructs a new instance of MouseInputHandler.

Parameters:

source - a source component

destination - a destination component

event - a mouse event

Method Detail

mouseClicked

public void mouseClicked(MouseEvent e)

Description copied from interface: MouseListener

Invoked when the mouse button has been clicked (pressed and released) on a component.

Specified by:

mouseClicked in interface MouseListener

Parameters:

e - the event to be processed

mousePressed

public void mousePressed(MouseEvent e)

Description copied from interface: MouseListener

Invoked when a mouse button has been pressed on a component.

Specified by:

mousePressed in interface MouseListener

Parameters:

e - the event to be processed

mouseReleased

public void mouseReleased(MouseEvent e)

Description copied from interface: MouseListener

Invoked when a mouse button has been released on a component.

Specified by:

mouseReleased in interface MouseListener

Parameters:

e - the event to be processed

mouseEntered

public void mouseEntered(MouseEvent e)

Description copied from interface: MouseListener

Invoked when the mouse enters a component.

Specified by:

mouseEntered in interface MouseListener

Parameters:

e - the event to be processed

mouseExited

public void mouseExited(MouseEvent e)

Description copied from interface: MouseListener

Invoked when the mouse exits a component.

Specified by:

mouseExited in interface MouseListener

Parameters:

e - the event to be processed

mouseDragged

public void mouseDragged(MouseEvent e)

Description copied from interface: MouseMotionListener

Invoked when a mouse button is pressed on a component and then dragged. MOUSE_DRAGGED events will continue to be delivered to the component where the drag originated until the mouse button is released (regardless of whether the mouse position is within the bounds of the component).

Due to platform-dependent Drag&Drop implementations, MOUSE_DRAGGED events may not be delivered during a native Drag&Drop operation.

Specified by:

mouseDragged in interface MouseMotionListener

Parameters:

e - the event to be processed

mouseMoved

public void mouseMoved(MouseEvent e)

Description copied from interface: MouseMotionListener

Invoked when the mouse cursor has been moved onto a component but no buttons have been pushed.

Specified by:

mouseMoved in interface MouseMotionListener

Parameters:

e - the event to be processed

removeFromSource

protected void removeFromSource()

Removes an event from the source.
