public class VirtualWindowItem
extends RectangleItem

A rectangle item, drawn on a VirtualView's annotation layer, that represents one BaseView's thumbnail location within the virtual desktop.

The constructor links the two objects both ways: baseView.setVirtualItem(this) lets the real view drive this item's position, while this item's own drag handling (modify()) is translation-only (not resizable or rotatable) and, on drag completion, moves the represented BaseView to match. Selection is a no-op; these items are not independently selectable/deselectable the way a normal drawn item is.

Constructor Details

VirtualWindowItem

public VirtualWindowItem(VirtualView vview,
 BaseView baseView)

Create a virtual window item that represents a base view inside a virtual view.

Parameters:

vview - the virtual view this item is in.

baseView - the base view this item represents.

Method Details

doubleClicked

public void doubleClicked(MouseEvent mouseEvent)

Called when the item was double clicked. The default implementation is to edit the item's properties. Here we want a no-op.

Overrides:

doubleClicked in class AItem

Parameters:

mouseEvent - the causal event.

setSelected

public void setSelected(boolean selected)

Sets whether this item is marked as selected. Here we want a no-op.

Overrides:

setSelected in class AItem

Parameters:

selected - the new value of the flag.

modify

public void modify()

A modification such as a drag, resize or rotate is continuing.

Overrides:

modify in class PathBasedItem

stopModification

public void stopModification()

A modification such as a drag, resize or rotate has ended.

Overrides:

stopModification in class AItem

drawItem

public void drawItem(Graphics2D g2,
 IContainer container)

Custom drawer for the item.

Overrides:

drawItem in class PathBasedItem

Parameters:

g2 - the graphics context.

container - the graphical container being rendered.

setLocation

public void setLocation()

Set the location of this item based on the location of the base view. This should be called whenever the base view moves.

getBaseView

public BaseView getBaseView()

Get the base view that this item represents

Returns:

the base view
