isIdentified

public boolean isIdentified(View view)

Determines whether the specified view is the one that is currently identified.

Parameters:

view -

Returns:

boolean

setIdentifiedView

public void setIdentifiedView(View view)

getIdentifiedView

public View getIdentifiedView()

isObjectIdentified

public boolean isObjectIdentified(View view)

Deprecated.

Determines whether the specified view is the one that is currently identified in a way that indicates that the object itself (vs the view) is of interest.

Parameters:

setStatus

public void setStatus(java.lang.String string)

addIcon

public void addIcon(DesktopView view)

Adds a view to the list of iconized views for this workspace and re-layout all the views. The icon's position is also limited so it is inside the bounds of this frame.

Parameters:

view - the view to add

addNotificationView

public void addNotificationView(ObjectView view)

addRootView

public void addRootView(RootView view)

Adds a view to the list of open view views for this workspace and re-layout all the views. The open view's position is also limited so it is inside the bounds of this frame.

Parameters:

view - the view to add

clearOverlayView

public void clearOverlayView()

public void dragObjectIn(ObjectDrag drag)

Description copied from interface: DragTarget

Called as an object drag moves into this view

Specified by:

dragObjectOut

public void dragObjectOut(ObjectDrag drag)

Description copied from interface: DragTarget

Called as an object drag moves out of this view

Specified by:

Called when a dragged object is dropped onto this view.

Specified by:

hasFocus

public boolean hasFocus(AbstractValueView view)

identifyView

public View identifyView(Location framePosition,
                         View current)

Returns the View that is currently under the pointer. Works through each top-level view and when the mouse is found in the that the same method is then called within that view, and so on. This ensures that views within views are identified. An optional parameter ensures that an already identified view is not returned. This is used when the dragged view needs to be ignored so a drop target can be identified.

Specified by:

identifyView in interface View

Overrides:

identifyView in class AbstractView

Parameters:

framePosition - the mouse position within the frame

current - the object that is being dragged, or null if none

Returns:

Component

public void layoutIcons()

limitBounds

public void limitBounds(View view)

Limits the bounds of the given view (when being moved or dropped) so its never extends outside the bounds of the containing open view

              throws java.lang.CloneNotSupportedException

Description copied from interface: View

Creates a new concrete view, using this view as a prototype, reassigning the naked object in the process. The field is the field within the parent view's object that this field represents, and is null if the view is not part of another - i.e. it is not a field within an object.

Specified by:
