Sign up using Facebook. If a cell’s default editor allows text entry, you get some error checking for free if the cell’s type is specified as something other than String or Object. You just create a subclass and implement the setValue method so that it invokes setText or setIcon with the appropriate string or image.
When using a sorter, always remember to translate cell coordinates. To specify that cells in a particular column should use a renderer, you use the TableColumn method setCellRenderer.
By default, the cell renderer for a Number -containing column uses a single JLabel instance to draw the appropriate numbers, right-aligned, on the column’s cells. It was not designed to handle fully independent cell selections. Setting up a combo box as an editor is simple, as the following example shows.
Ocurs column names remain visible at the top of the viewing area when the table data is scrolled. Here is typical code for creating a scroll pane that serves as a container for a table:. As previously noted, the text the user enters in the “Filter Text” text field defines a filter that determines jjava rows are shown.
You can specify selection by cell in multiple interval selection mode, but the result is courz table that does not produce useful selections. And then I fill the table from my database depending on a condition finished-not started yet – and in progress:. Here are a couple ways to do so:. 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.
JTable (Java Platform SE 6 b18)
However, according to your getColumnClass When using a sorter, always remember to translate cell coordinates. You may also notice that changing any of the three selection options can affect the others. The override of getTableCellEditorComponent sets the formatted text field’s value property and not just the text property it inherits from JTextField before the editor is shown.
With the JTable class you can display tables of data, optionally allowing the user to edit the data. The program TableToolTipsDemo shows how.
How to Use Tables
Usually you do not have to explicitly specify a check box as an editor, since columns with Boolean data automatically use a check box renderer and editor. When the table becomes wider or narrower which might happen when the user resizes the window containing the tableall the column widths change appropriately. The error checking is a side effect of converting the entered text into an object of the proper type.
JTable uses a very simple concept of selection, managed as an intersection of rows and columns.
Uses renderers to display tool tips for the sport cells. Here is the code from TableDialogEditDemo. To specify a cell-specific renderer, you need to define a JTable subclass that overrides the getCellRenderer method.
In the screenshot below, a user has run the program, clicked in the first row, then control-clicked in the third row. Currently, tables put the following types of data in the list:. A special highlight indicates that the “Snowboarding” cell is editable. Here is typical code for cour a scroll pane that serves as a container for a table:. The code is fairly straightforward, except perhaps for the call to convertColumnIndexToModel.
This list is initialized by the table, but you can add to it or change it. All of the radio buttons under “Selection Mode” invoke JTable.
Generally, you implement your table model in a subclass of the AbstractTableModel class. The entire first row is selected, indicating that you have selected Kathy Smith’s data. Here are the topics this section covers: Position the cursor over “First Name”. If you are using a table without a scroll pane, then you must get the table header component and place it yourself.
A table model can have a set of listeners that are notified whenever the table data changes. If DefaultTableModel is not a suitable base class for your custom table model class, consider subclassing AbstractTableModel.
