JDataModelDisplay

public class JSplittedDataDisplay
extends AbstractDisplayable
implements DataCanvasProviding, DataObserver

A splitted data display should always be used when two interlinked JDataCanvas should be displayed. A splitted data display defines a master data canvas that displays to the top or left, and a slave data canvas to the bottom or right. If the user zooms in the master, the slave zoom changes according to the KEY_TRANSFER.

Constructor Detail

JSplittedDataDisplay

public JSplittedDataDisplay(Map<String,String> prop)

Creates a new splitted display. The KEY_MASTERCANVAS and KEY_SLAVECANVAS must be set.

Method Detail

init

public void init()

Initializes the two data canvas. Assigns a zoom cursor to it.

Specified by:

init in interface Initializable

Overrides:

init in class PropertyResources

getMainCanvas

public JDataCanvas getMainCanvas()

Returns the master canvas.

Specified by:

getMainCanvas in interface DataCanvasProviding

getComposingCanvases

public Collection<JDataCanvas> getComposingCanvases()

Returns the master and the slave canvas.

Specified by:

getComposingCanvases in interface DataCanvasProviding

joinZoom

private boolean joinZoom()

Tries to join the two data canvas together.

getMasterCanvas

public JDataCanvas getMasterCanvas()

Returns the empty master canvas. This is the method for objects that want to draw on the master canvas once it is constructed.

getSlaveCanvas

public JDataCanvas getSlaveCanvas()

Returns the empty slave canvas. This is the method for objects that want to draw on the slave canvas once it is constructed.

This method is called if one of the delete-linked sets cahnged. We scan for data cards in the linked canvas with identical keys and delete them. Additionally, a reference to this delted data is kept locally. If data has been added, we look if there has been delete data in the linked canvas that we can restore.

Specified by:

dataChanged in interface DataObserver
