Method Summary

Modifier and Type	Method and Description
void	addMouseInputListener(MouseInputListener listener) Adds a listener to this representative, it is not defined what to do with that listener, but most subclasses would just add the listener to their component.
Component	getComponent() Gets the Component which represents the element.
DockElement	getElement() Gets the element which is represented by this.
Point	getPopupLocation(Point click, boolean popupTrigger) Tells whether a popup menu should be opened when the user clicks at click with the mouse.
boolean	isUsedAsTitle() Tells whether this DockElementRepresentative is used as title. Some modules grant more rights to titles than to non-titles, i.e.
void	removeMouseInputListener(MouseInputListener listener) Removes a listener from this representative.
boolean	shouldFocus() Tells whether a click onto this component should transfer the focus either to this component or to the Dockable.
boolean	shouldTransfersFocus() Tells whether a click onto this component should transfer the focus to the Dockable or not.

Constructor Detail

SimpleDockElementRepresentative

public SimpleDockElementRepresentative(DockElement element,
                                       Component component)

Creates a new SimpleDockElementRepresentative.

Parameters:

element - the element which is represented by this

component - the component to which this adds listeners

Method Detail

addMouseInputListener

public void addMouseInputListener(MouseInputListener listener)

Description copied from interface: DockElementRepresentative

Adds a listener to this representative, it is not defined what to do with that listener, but most subclasses would just add the listener to their component. It is valid to do nothing.

Specified by:

addMouseInputListener in interface DockElementRepresentative

Parameters:

listener - the new listener

getComponent

public Component getComponent()

Description copied from interface: DockElementRepresentative

Gets the Component which represents the element. The result of this method must not change.

Specified by:

getComponent in interface DockElementRepresentative

Returns:

the component, never null

getElement

public DockElement getElement()

Description copied from interface: DockElementRepresentative

Gets the element which is represented by this. The result of this method must not change.

Specified by:

getElement in interface DockElementRepresentative

Returns:

the element, never null

getPopupLocation

public Point getPopupLocation(Point click,
                              boolean popupTrigger)

Description copied from interface: DockElementRepresentative

Tells whether a popup menu should be opened when the user clicks at click with the mouse. If yes, then the top left edge of the popup should be returned, otherwise null should be returned.

Specified by:

getPopupLocation in interface DockElementRepresentative

Parameters:

click - the location where the user clicked with the mouse

popupTrigger - whether the invocation is the systems popup trigger or not. Many implementations of this method will return click in case of true, and null in case of false

Returns:

the preferred location of a popup or null if no popup-menu should be opened

isUsedAsTitle

public boolean isUsedAsTitle()

Description copied from interface: DockElementRepresentative

Tells whether this DockElementRepresentative is used as title.
Some modules grant more rights to titles than to non-titles, i.e. a DockRelocator can allow drag & drop only for titles.
Normally a Dockable should have only one element that is a title, so if in doubt return false.

Specified by:

isUsedAsTitle in interface DockElementRepresentative

Returns:

true if this representative should be seen as title

shouldFocus

public boolean shouldFocus()

Description copied from interface: DockElementRepresentative

Tells whether a click onto this component should transfer the focus either to this component or to the Dockable.

Specified by:

shouldFocus in interface DockElementRepresentative

Returns:

true if clicking this component should influence focus

shouldTransfersFocus

public boolean shouldTransfersFocus()

Description copied from interface: DockElementRepresentative

Tells whether a click onto this component should transfer the focus to the Dockable or not. If this object is a Dockable, then a result of true might change the currently focused item of itself. This property is ignored if DockElementRepresentative.shouldFocus() returns false.

Specified by:

shouldTransfersFocus in interface DockElementRepresentative

Returns:

whether to change the focused component or not

removeMouseInputListener

public void removeMouseInputListener(MouseInputListener listener)

Description copied from interface: DockElementRepresentative

Removes a listener from this representative.

Specified by:

removeMouseInputListener in interface DockElementRepresentative

Parameters:

listener - the listener to remove
