est-il possible d’appliquer le filtre sur une collection d’object d’une JTable? private JTable table; table = new JTable(model);. table. catch ( but all get is the link of the image: Then that means you are storing text in that column. 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.

Listeners are instances of TableModelListener. 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. In addition to reordering the results, a table sorter can also specify jable rows will be displayed.
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. This section shows you how to use both techniques. Invoking print on a normal Swing application brings up a standard printing dialog box. The automatic checking of user-entered strings occurs when the default editor attempts to create a new instance of the class associated with the cell’s column.
In the following example code, you explicitly create a sorter object so you can later use it to specify a filter:. It might even generate the data at execution time.
JTable (Java Platform SE 6 b18)
Rules are followed in the order listed below; the first rule that provides the sorter with a Comparator is used, and the remainining rules ignored. It implements TableCellEditor ‘s superinterface, CellEditorsaving you the trouble of implementing the jtzble firing code necessary for cell editors. Notice the outline around the last cell clicked; cohrs is how the Metal look and feel highlights the lead selection. You can think of the renderer as a configurable ink stamp that the table uses to stamp appropriately formatted data onto each cell.
Your implementation of this method should set up the rendering component to reflect the passed-in state, and then return the component. Modifies TableDemo to have a cell renderer and editor that ciurs a color and let you choose a new one, using a color chooser dialog. If you edit an item in the first column of the table, the new value is reflected in the list. This is because cell selection is not supported in this mode in the demo.
The following code formats a string containing the row and column of the lead selection:. Setting cellSelectionEnabled to a value has the side effect of also setting both rowSelectionEnabled and columnSelectionEnabled to that value.
PrinterExceptionwhich is a ckurs exception ; jtabld why the above example uses a try As you can see, users can rearrange columns in tables. The program TableToolTipsDemo shows how. This section shows you how to use both techniques. This section tells you how to create and specify a cell renderer.
How to Use Tables

Here is an example that sorts the table used in the examples by the first two columns. This distinction does not matter unless your viewed data has been rearranged by sorting, filtering, or user manipulation of columns.
The column changes size, and the other columns adjust to fill the remaining space. Before you go on to the next few tasks, you need to understand how tables draw their cells. 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.
Now press the mouse button and drag to the right. Resize the window containing the table so that it’s bigger than necessary to display the whole table. The following example brings together the ideas discussed in this section. JTable uses a very simple concept of selection, managed as an intersection of rows and columns. To customize initial column widths, you can invoke setPreferredWidth on each of your table’s columns. The advantage of these constructors is that they are easy to use.
To determine which Comparator to use for a column, TableRowSorter attempts to apply each of the following rules in turn. 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.
The entire first row is selected, indicating that you have selected Kathy Smith’s data.
This section tells you how to create and specify a cell renderer. When the user explicitly resizes columns, the columns’ preferred widths are set such that the user-specified sizes become the columns’ new current widths. By default, all columns in a table start out with equal width, and the columns automatically fill the entire width of the jtale. The bold line of code sets up the combo box as the editor for a specific column.
To specify the sort order and sort precedence for columns, invoke setSortKeys. Modifies TableDemo to use a custom editor a combo box for all data in the Sport column. This distinction does not matter unless your viewed data has been rearranged by sorting, filtering, or user manipulation of columns.
Here are the topics this section covers:. Here is a picture of a table with a dialog that serves, indirectly, as a cell editor. The following code implements the tool tips. Your model might hold its data in an array, vector, or hash map, or it might get the data from an outside source such as a database. The ccours code is from TableRenderDemo.
