This cell is known as the lead selection ; it is sometimes called jtzble cell with the focus” or “the current cell”. Position the cursor over “First Name”.

For example, in a column whose cells have type Integerwhen the user types in “” the default editor creates the corresponding Integer using code equivalent to new Integer “”. A table model can have a set of listeners that are notified whenever the table data changes. Jtablw does not contain or cache data; it is simply a view of your data.

On a headless application, the table is simply printed. Now you can only select one row at a time.

How to Use Tables

Since prepareRenderer provides the view index, you need to translate the view index to a model index so you can be sure the intended column has been selected. You will see the tool tips when you mouse over any column header except for the first two.

To retrieve the coordinates of the lead selection, refer to the selection models for the table itself and for the table’s column model. Here is an example that sorts the table used in the examples by the first two columns.

The easiest way to provide a sorter object is to set autoCreateRowSorter bound property to true:. To specify that cells in a particular column should use a renderer, you use the TableColumn method setCellRenderer.

As you can see, users can rearrange columns in jtaboe. Resize the window containing the table so that it’s bigger than necessary to display the whole table. Then, after making sure the rendering component is a JComponentinvoke the setToolTipText method on it.

However, these constructors also have disadvantages:. Demonstrates sorting and filtering, and how this can cause the view coordinates to diverge from the model coordinates. The easiest way to print out a table is to invoke JTable. That call is necessary because if the user moves the cous around, the view’s index for the column will not match the model’s index for the column.

JTable (Java Platform SE 6 b18)

Every table object uses a table model object to manage jtabble actual table data. Often, different column headers require different tool tip text. For 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. The next few sections tell you how to customize display and editing by jaca renderers and editors.

When a table uses a sorter, the data the users sees may be in a different order than that specified by the data model, and may not include all rows specified by the data model. This relationship is illustrated below. In a subsequent example, newFilter is invoked every time the text field changes.

For example, regexFilter returns a RowFilter jtabl filters based on a regular expression. The default editor creates this instance using a constructor that takes a String as an argument. Position the cursor just to the right of a column header. As you can see, the code is pretty simple.

Comparator objects to sort its rows. This section shows you how to use both techniques. To retrieve the current selection, use JTable.
