Class LwCursorManager

java.lang.Object
  |
  +--org.zaval.lw.LwCursorManager

All Implemented Interfaces:

java.util.EventListener, LwManager, LwMouseListener, LwMouseMotionListener

public class LwCursorManager

extends java.lang.Object

implements LwManager, LwMouseListener, LwMouseMotionListener

This manager is used to support mouse cursor changing for a lightweight component. To support the mouse cursor changing there are two ways :

• The light weight component has to implement the Cursorable interface. From the moment the manager will use the implementation to get current cursor type.
• The manager provides the setCursorType method to define the mouse cursorable interface that will resolve a cursor type for the component.

Constructor Detail

LwCursorManager

public LwCursorManager()

dispose

public void dispose()

Description copied from interface: LwManager

Disposes the manager. The method is supposed to be used for disposing different manager related structures to free system resources. The method is invoked by LwVCL core when the manager ends its "live".

Specified by:

dispose in interface LwManager

mouseEntered

public void mouseEntered(LwMouseEvent e)

Description copied from interface: LwMouseListener

Invoked when the mouse enters a light weight component.

Specified by:

mouseEntered in interface LwMouseListener

Following copied from interface: org.zaval.lw.event.LwMouseListener

Parameters:

e - the specified mouse event.

mouseExited

public void mouseExited(LwMouseEvent e)

Description copied from interface: LwMouseListener

Invoked when the mouse exits a light weight component.

Specified by:

mouseExited in interface LwMouseListener

Following copied from interface: org.zaval.lw.event.LwMouseListener

Parameters:

e - the specified mouse event.

endDragged

public void endDragged(LwMouseEvent e)

Description copied from interface: LwMouseMotionListener

Invoked when the mouse ends dragged.

Specified by:

endDragged in interface LwMouseMotionListener

Following copied from interface: org.zaval.lw.event.LwMouseMotionListener

Parameters:

e - the specified mouse event.

mouseMoved

public void mouseMoved(LwMouseEvent e)

Description copied from interface: LwMouseMotionListener

Invoked when the mouse pointer has been moved on a light weight component (with no buttons no down).

Specified by:

mouseMoved in interface LwMouseMotionListener

Following copied from interface: org.zaval.lw.event.LwMouseMotionListener

Parameters:

e - the specified mouse event.

startDragged

public void startDragged(LwMouseEvent e)

Description copied from interface: LwMouseMotionListener

Invoked when the mouse starts dragged.

Specified by:

startDragged in interface LwMouseMotionListener

Following copied from interface: org.zaval.lw.event.LwMouseMotionListener

Parameters:

e - the specified mouse event.

mouseDragged

public void mouseDragged(LwMouseEvent e)

Description copied from interface: LwMouseMotionListener

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

Specified by:

mouseDragged in interface LwMouseMotionListener

Following copied from interface: org.zaval.lw.event.LwMouseMotionListener

Parameters:

e - the specified mouse event.

mouseClicked

public void mouseClicked(LwMouseEvent e)

Description copied from interface: LwMouseListener

Invoked when the mouse button has been clicked on a light weight component.

Specified by:

mouseClicked in interface LwMouseListener

Following copied from interface: org.zaval.lw.event.LwMouseListener

Parameters:

e - the specified mouse event.

mousePressed

public void mousePressed(LwMouseEvent e)

Description copied from interface: LwMouseListener

Invoked when the mouse button has been pressed on a light weight component.

Specified by:

mousePressed in interface LwMouseListener

Following copied from interface: org.zaval.lw.event.LwMouseListener

Parameters:

e - the specified mouse event.

mouseReleased

public void mouseReleased(LwMouseEvent e)

Description copied from interface: LwMouseListener

Invoked when the mouse button has been released on a light weight component.

Specified by:

mouseReleased in interface LwMouseListener

Following copied from interface: org.zaval.lw.event.LwMouseListener

Parameters:

e - the specified mouse event.

setCursorable

public void setCursorable(LwComponent target,
                          Cursorable c)

Sets the specified cursorable interface for the given component. To set the default cursor type for the component use null as the cursorable interface. The interface points the manager what cursor type should be set for the specified component.

Parameters:

target - the component.

c - the specified cursorable interface.

getCursorable

public Cursorable getCursorable(LwComponent target)

Gets the current cursorable interface for the given component.

Parameters:

target - the given component.

Returns:

a current cursor type.

getCursorType

public int getCursorType()

Gets the current cursor type.

Returns:

a current cursor type.
