Class TableColumnAdjuster

java.lang.Object
org.jjazz.uiutilities.api.TableColumnAdjuster
All Implemented Interfaces:
PropertyChangeListener, EventListener, TableModelListener
public class TableColumnAdjuster extends Object implements PropertyChangeListener, TableModelListener
Class to manage the widths of colunmns in a table.

Various properties control how the width of the column is calculated. Another property controls whether column width calculation should be dynamic. Finally, various Actions will be added to the table to allow the user to customize the functionality.

This class was designed to be used with tables that use an auto resize mode of AUTO_RESIZE_OFF. With all other modes you are constrained as the width of the columns must fit inside the table. So if you increase one column, one or more of the other columns must decrease. Because of this the resize mode of RESIZE_ALL_COLUMNS will work the best.

Example:
table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
TableColumnAdjuster tca = new TableColumnAdjuster(table);
tca.adjustColumns();
