You have a couple of problems that I can see: You code. This page provides Java code examples for umnModel . The examples are extracted from open source Java projects.

The automatic checking of user-entered strings occurs when the default editor attempts to create jtabke new instance of the class associated with the cell’s column.

If extending DefaultTableCellRenderer is insufficient, you can build a renderer using another superclass. Instead, a single cell renderer is generally used to draw all of the cells ckurs contain the same type of data. A table model can have a set of listeners that are notified whenever the table data changes.

JTable (Java Platform SE 6 b18)

If you did not, then the table invokes the table clurs getColumnClass method, which gets the data type of the column’s cells. Here is typical code for creating a scroll pane that serves as a container for a table:. TableCellRenderer requires just one method: Listeners are instances of TableModelListener.

For example, the following code makes the first cell in the first column of the table use a custom renderer:. 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. Whether you are setting the editor for a single column of cells using the TableColumn setCellEditor method or for a specific type of data using the JTable setDefaultEditor methodyou specify the editor using an argument that adheres to the TableCellEditor interface.

This class implements a simple framework for constructing TableModelEvent objects. The return value indicates whether the user went ahead with the print job or cancelled it. You will see the tool tips when you mouse over any column header except for the first two.

The precedence of the columns in the sort is indicated by the order of the sort keys in the sort key list. As the preceding code shows, implementing a table model can be simple. Sign up or log in Sign up using Google. Instead, the existing preferred widths are used to calculate new column widths to fill the available space.

See below the code taken from TableDemo. Table sorting and filtering is managed by a sorter object. Basically, it creates a subclass of JTableHeader that overrides the getToolTipText MouseEvent method so that it returns the text for the current column. If you implement a class used as a column data type, you can use the default editor if your class supplies a constructor that takes a single argument of type String.

This is known as filtering. To retrieve the coordinates of the lead selection, refer to the selection models for the table itself and for the table’s column model.

In the screenshot below, a user has run the program, clicked in the first row, then control-clicked in the third row. The rest of this section shows you how to accomplish some common table-related tasks.

It implements TableCellEditor ‘s superinterface, CellEditorsaving you the trouble of implementing the event firing code necessary for cell editors. Demonstrates sorting and filtering, and how this can cause the view coordinates to diverge from the model coordinates. You can specify selection by cell in multiple interval selection mode, but the result is a table that does not produce useful selections.

The next few sections tell you how to customize display and editing by specifying renderers and editors. Setting cellSelectionEnabled to a value has the side effect of also setting both rowSelectionEnabled and columnSelectionEnabled to that value.

How to Use Tables

Use a selection listener as vours in Detecting User Selections. To retrieve the coordinates of the lead selection, refer to the selection models for the table itself and jtablf the table’s column model. Then, after making sure the rendering component is a JComponentinvoke the setToolTipText method on it.

This jtab,e be a complex procedure, but is already implemented in DefaultTableModel. An example of adding code to a cell renderer is in TableDialogEditDemo. Does not include code to specify column widths or detect user editing. As you can see, users can rearrange columns in tables. Adds single selection and selection detection to SimpleTableDemo. Your implementation of this method should set up the rendering component to reflect the passed-in state, and then return the component.

Before you go on to the next few tasks, you need to understand how tables draw their cells. The bold line of code sets up the combo box as the editor for a specific column. Uses renderers to display tool tips for the sport cells.
