It is easy to customize the text or image rendered by the default renderer, DefaultTableCellRenderer.

It accomplishes this by first setting up a formatted text field to use an integer format and have the specified minimum and maximum values, using the API described in How to Use Formatted Text Fields.

If the constructor throws an exception, the cell’s outline turns red and refuses to let focus move out of the cell. The last cell that the user indicated gets a special indication; in the Metal look and feel, the cell is outlined.

TableColumn supplies getter and setter methods for the minimum, preferred, and maximum widths of a column, as well as a method for getting the current width.

How to Use Tables

User selections generate a number of events. Ccours an example of setting cell widths based on an approximation of the space needed to draw the cells’ contents, see the initColumnSizes method in TableRenderDemo. Modifies TableDemo to have a cell renderer and editor that display a color and let you choose a new one, using a color chooser dialog. If the text isn’t valid, your implementation of stopCellEditing puts up a dialog that gives the user the option of continuing to edit or reverting to the last good ntable.

The following code from TablePrintDemo. Under “Selection Mode” there are a set of radio buttons.

With the JTable class you can display tables couds data, optionally allowing the user to edit the data. Basically, it creates a subclass of JTableHeader that overrides the getToolTipText MouseEvent method so that it returns the text for the current column. When the user starts to edit a cell’s data, a cell editor takes over the cell, controlling the cell’s editing behavior.

The code is fairly straightforward, except perhaps for the call to convertColumnIndexToModel. If you click on the “Single Interval Selection” radio button, you can select a set of rows that must be contiguous. Basically, it creates a subclass of JTableHeader that overrides the getToolTipText MouseEvent method so that it returns the text for the current column. The only part that is a bit tricky is the call to fireEditingStopped at the end of the editor button’s action handler.

As the preceding code shows, each column in a table is represented by a TableColumn object.

JTable does not contain or cache data; it is simply a view of your data. To specify more precise column types, the table model must define the getColumnClass method appropriately, as demonstrated by TableDemo.

Setting rowSelectionEnabled and columnSelectionEnabled to different values has the side effect jyable also setting cellSelectionEnabled to false.

There is also a text pane that logs selection events. For more sophisticated kinds of sorting, subclass TableRowSorter or its parent class javax. You can specify cell renderers and editors either by column or by data type.

These include the code snippets earlier in this section, which provide a sorter for the main table, and use a text field to supply the filtering regular expression.

Does not include code to specify column widths or detect user editing. You may notice that the “Cell Selection” checkbox is disabled in multiple interval selection mode.

Here is a picture of a typical table displayed within a scroll pane: Here is a picture of a typical table displayed within a scroll pane: JTable automatically updates the three bound variables as necessary to keep them consistent.

Although the tool tip text in the previous example is static, you can also implement tool tips whose text changes depending on the state of the cell or program. These include the code snippets earlier in this section, which provide a sorter for the main table, and use a text field to supply the filtering regular expression.
