public class TableNodeView
extends NodeView

Table view on a DataTable. It simply uses a JTable to display the data table. If the node has not been executed or is reset, the view will print "<no data>". The view adds also a menu entry to the menu bar where the user can synchronize the selection with a global hilite handler.

Constructor Detail

TableNodeView

public TableNodeView(TableNodeModel nodeModel)

Starts a new TableNodeView displaying "<no data>". The content comes up when the super class NodeView calls the modelChanged() method.

hasData

public boolean hasData()

Checks if there is data to display. That is: The model's content model (keeping the cache and so on) needs to have a DataTable to show. This method returns true when the node was executed and false otherwise.

Returns:

true if there is data to display

hasHiLiteHandler

public boolean hasHiLiteHandler()

Checks is property handler is set.

Returns:

true if property handler set

TableContentView.hasHiLiteHandler()

setHiLiteHandler

public void setHiLiteHandler(HiLiteHandler hiLiteHdl)

Sets a new handler for this view.

Parameters:

hiLiteHdl - the new handler to set, may be null to disable any brushing

setShowColorInfo

public void setShowColorInfo(boolean isShowColor)

Shall row header encode the color information in an icon.
