interface org.aswing.Viewportable

A component that allows the user to select one or more objects from a list. A separate model, ListModel, represents the contents of the list. It's easy to display an array objects, using a JList constructor that builds a ListModel instance for you:

// Create a JList that displays the strings in data[]

The JTable is used to display and edit regular two-dimensional tables of cells.

The JTable has many facilities that make it possible to customize its rendering and editing but provides defaults for these features so that simple tables can be set up easily. For example, to set up a table with 10 rows and 10 columns of numbers:

 class MyTableModel extends AbstractTableModel{
   public function getColumnCount():int { return 10; }
   public function getRowCount():int { return 10;}
   public getValueAt(row:int, col:int) { return row*col; }
 };
 var dataModel:MyTableModel = new MyTableModel();
 var table:JTable = new JTable(dataModel);
 var scrollpane:JScrollPane = new JScrollPane(table);

Note that if you wish to use a JTable in a standalone view (outside of a JScrollPane) and want the header displayed, you can get it using {@link #getTableHeader} and display it separately.

When designing applications that use the JTable it is worth paying close attention to the data structures that will represent the table's data. The DefaultTableModel is a model implementation that uses a Vector of Vectors of Objects to store the cell values. As well as copying the data from an application into the DefaultTableModel, it is also possible to wrap the data in the methods of the TableModel interface so that the data can be passed to the JTable directly, as in the example above. This often results in more efficient applications because the model is free to choose the internal representation that best suits the data. A good rule of thumb for deciding whether to use the AbstractTableModel or the DefaultTableModel is to use the AbstractTableModel as the base class for creating subclasses and the DefaultTableModel when subclassing is not required.

The JTable uses integers exclusively to refer to both the rows and the columns of the model that it displays. The JTable simply takes a tabular range of cells and uses getValueAt(int, int) to retrieve the values from the model during painting.

By default, columns may be rearranged in the JTable so that the view's columns appear in a different order to the columns in the model. This does not affect the implementation of the model at all: when the columns are reordered, the JTable maintains the new order of the columns internally and converts its column indices before querying the model.

A JTextArea is a multi-line area that displays text.

A control that displays a set of hierarchical data as an outline.

JViewport is an basic viewport to view normal components. Generally JViewport works with JScrollPane together, for example:
