Constructor Detail

TableRowMarginSupport

public TableRowMarginSupport(JTable table,
                             JScrollPane scrollPane)

Method Detail

getTable

public JTable getTable()

getRowCount

public int getRowCount()

Description copied from interface: RowMarginSupport

Gets the total row count in the component.

Returns:

the total row count.

scrollTo

public void scrollTo(int beginRow,
                     int endRow,
                     boolean select)

Description copied from interface: RowMarginSupport

Selects the rows. Note the beginning row index is not always less than the ending index. It depends on the mouse dragging direction. If user presses and drags upward on the margin, the end index will be smaller than the beginning index. In the implementation of this method, it should try to make the end index visible so that the dragging on the margin will auto-scroll when dragging outside the boundary.

Parameters:

beginRow - the beginning row index

endRow - the end row index

select - to select the rows. True to select the row. False to scroll the rows visible only without selecting them.

getRowHeight

public int getRowHeight(int row)

Description copied from interface: RowMarginSupport

Gets the row height.

Parameters:

row - the row index.

Returns:

the row height.

positionToRow

public int positionToRow(int position)

Description copied from interface: RowMarginSupport

Gets the actual row index corresponding to the position the margin.

Parameters:

position - the position on the margin.

Returns:

the row index corresponding to the position the margin.

rowToPosition

public int rowToPosition(int row)

Description copied from interface: RowMarginSupport

Gets the position on the margin corresponding to the actual row index.

Parameters:

row - the actual row index

Returns:

the position on the margin corresponding to the row index. Integer.MIN_VALUE if the row is not visible.

getBaselineAdjustment

public int getBaselineAdjustment()

Description copied from interface: RowMarginSupport

Gets the baseline adjustment so that the text on the margin aligns properly with the text on the component. You can override it to adjust the value if you notice the texts don't align.

Specified by:

getBaselineAdjustment in interface RowMarginSupport

Overrides:

getBaselineAdjustment in class AbstractRowMarginSupport

Returns:

the baseline adjustment.

installListeners

public void installListeners(MarginSupport.RepaintCallback repaintCallback,
                             MarginSupport.ModelChangedCallback modelChangedCallback)

Description copied from interface: MarginSupport

Installs the listener to the component so that the RepaintCallback will be triggered when a repaint is needed, and the ModelChangedCallback will be triggered when the model is changed.

Specified by:

installListeners in interface MarginSupport

Overrides:

installListeners in class AbstractMarginSupport

Parameters:

repaintCallback - the callback when a repaint is needed.

modelChangedCallback - the callback when the model of the component is changed. By default, the parameter is null unless the MarginComponent overrides the AbstractMargin.createModelChangedCallback() method is overridden to return a valid callback.

uninstallListeners

public void uninstallListeners(MarginSupport.RepaintCallback repaintCallback,
                               MarginSupport.ModelChangedCallback modelChangedCallback)

Description copied from interface: MarginSupport

Uninstalls all the listeners installed in MarginSupport.installListeners(com.jidesoft.margin.MarginSupport.RepaintCallback, com.jidesoft.margin.MarginSupport.ModelChangedCallback).

Specified by:

uninstallListeners in interface MarginSupport

Overrides:

uninstallListeners in class AbstractMarginSupport

Parameters:

repaintCallback - the callback when a repaint is needed.

modelChangedCallback - the callback when the model of the component is changed. By default, the parameter is null unless the MarginComponent overrides the AbstractMargin.createModelChangedCallback() method is overridden to return a valid callback.
