Interface jclass.table.JCTblCallback

public interface JCTblCallback

extends Object

When a low-level event such as a mouse click occurs, the sender invokes the call method to notify the applicaton so it can perform non-default actions. This is equivalent to Motif's callback mechanism, and does not force the developer to create a subclass.

BEGIN

The value of an Info object's stage member.

CELL_VALUE

Called whenever the table displays an empty cell (one which has with no value as described by the internal vector of the table).

CREATE_COMPONENT

Called when a single component has been specified for multiple cells, or a component is specified in the componentList value in an HTML file.

DISPLAY_COMPONENT

Called before drawing a component in a cell or label (when the table is initially displayed and when the cell is scrolled into view).

END

The value of an Info object's stage member.

ENTER_CELL

Called before and after completing a traversal from one cell to another.

EXTEND

The value of a JCSelectInfo object's stage member.

LABEL_VALUE

Called whenever the table displays an empty row or column label (one which has with no value as described by the internal vector of the table).

PAINT

Called both before and after a portion of the table is painted (whenever the table redraws or modifies an onscreen area).

RESIZE_CELL

Called as a user resizes a row and/or column.

SCROLL

Called when the table is scrolled.

SELECT

Called as a user selects cells.

SORT

Called after a call to sortByColumn().

TABLE_REASON

Base for all table reasons.

TRAVERSE_CELL

Called as a user traverses from one cell to another.

UNSELECT

The value of a JCSelectInfo object's stage member.

VALIDATE_CELL

Called when a cell/label has been edited, both before and after an edit has been committeed to cell or label value structures.

callback(Object, int, Object)

Called by the sender while it is processing.

  public final static int TABLE_REASON

Base for all table reasons.

  public final static int CREATE_COMPONENT

Called when a single component has been specified for multiple cells, or a component is specified in the componentList value in an HTML file. If no callback is supplied, a clone is created using the class' default constructor. The info argument is set to an instance of a JCCreateComponentInfo object.

See Also:

setComponent, JCCreateComponentInfo

  public final static int DISPLAY_COMPONENT

Called before drawing a component in a cell or label (when the table is initially displayed and when the cell is scrolled into view). The info argument is set to an instance of a JCDisplayComponentInfo object.

See Also:

JCDisplayComponentInfo

  public final static int TRAVERSE_CELL

Called as a user traverses from one cell to another. This callback is called after a user has committed a cell edit, and before moving the Text component to the next cell.

The info argument is set to an instance of a JCTraverseCellInfo object.

See Also:

JCTraverseCellInfo, traverse

  public final static int ENTER_CELL

Called before and after completing a traversal from one cell to another. The info argument is set to an instance of a JCEnterCellInfo object

See Also:

traverse, JCEnterCellInfo

  public final static int RESIZE_CELL

Called as a user resizes a row and/or column. The info argument is set to an instance of a JCResizeCellInfo object.

See Also:

JCResizeCellInfo

  public final static int SCROLL

Called when the table is scrolled. The info argument is set to an instance of a JCScrollInfo object.

See Also:

JCScrollInfo

  public final static int SELECT

Called as a user selects cells. The event is called for every cell selected in a range. The info argument is set to an instance of a JCSelectInfo object.

See Also:

JCSelectInfo

  public final static int SORT

Called after a call to sortByColumn(). The info argument is set to an instance of a JCSortInfo object.

See Also:

sortByColumn, JCSortInfo

  public final static int VALIDATE_CELL

Called when a cell/label has been edited, both before and after an edit has been committeed to cell or label value structures. The info argument is set to an instance of a JCValidateCellInfo object.

See Also:

commitEdit, traverse, JCValidateCellInfo

  public final static int CELL_VALUE

Called whenever the table displays an empty cell (one which has with no value as described by the internal vector of the table). This callback will be called during the initial table display, scrolling and table repaint. The info argument is set to an instance of a JCValueInfo object.

See Also:

JCValueInfo

  public final static int LABEL_VALUE

Called whenever the table displays an empty row or column label (one which has with no value as described by the internal vector of the table). This callback will be called during the initial table display, scrolling and table repaint. The info argument is set to an instance of a JCValueInfo object.

See Also:

JCValueInfo

  public final static int PAINT

Called both before and after a portion of the table is painted (whenever the table redraws or modifies an onscreen area).

The info argument is set to an instance of a JCPaintInfo object.

The value of a JCSelectInfo object's stage member.

  public final static int UNSELECT

The value of a JCSelectInfo object's stage member.

  public abstract boolean callback(Object caller,
                                   int reason,
                                   Object info)
