Table (Eclipse RAP 3.3.0-SNAPSHOT API Reference)

java.lang.Object
- org.eclipse.swt.widgets.Widget
- - org.eclipse.swt.widgets.Control
  - - org.eclipse.swt.widgets.Scrollable
    - - org.eclipse.swt.widgets.Composite
      - org.eclipse.swt.widgets.Table

All Implemented Interfaces:

Adaptable, Drawable
```
public class Table
extends Composite
```
Instances of this class implement a selectable user interface object that displays a list of images and strings and issues notification when selected.
The item children that may be added to instances of this class must be of type TableItem.
Style VIRTUAL is used to create a Table whose TableItems are to be populated by the client on an on-demand basis instead of up-front. This can provide significant performance improvements for tables that are very large or for which TableItem population is expensive (for example, retrieving values from an external source).
Here is an example of using a Table with style VIRTUAL:
```
  final Table table = new Table (parent, SWT.VIRTUAL | SWT.BORDER);
  table.setItemCount (1000000);
  table.addListener (SWT.SetData, new Listener () {
      public void handleEvent (Event event) {
          TableItem item = (TableItem) event.item;
          int index = table.indexOf (item);
          item.setText ("Item " + index);
          System.out.println (item.getText ());
      }
  });
 
```
Note that although this class is a subclass of Composite, it does not make sense to add Control children to it, or set a layout on it.

Styles:

SINGLE, MULTI, CHECK, FULL_SELECTION, HIDE_SELECTION, VIRTUAL

Events:

Selection, DefaultSelection, SetData

Note: Only one of the styles SINGLE, and MULTI may be specified.
IMPORTANT: This class is not intended to be subclassed.
Since:

1.0

    an object that can be cast to the given class or null if there is no adapter associated with the given class.
  - setData
```
public void setData(java.lang.String key,
           java.lang.Object value)
```
    Description copied from class: Widget
    
    Sets the application defined property of the receiver with the specified name to the given value.
    Applications may associate arbitrary objects with the receiver in this fashion. If the objects stored in the properties need to be notified when the widget is disposed of, it is the application's responsibility to hook the Dispose event on the widget and do so.
    
    Overrides:
    
    setData in class Control
    
    Parameters:
    key - the name of the property
    value - the new value for the property
    See Also:
    Widget.getData(String)
  - getColumnCount
```
public int getColumnCount()
```
    Returns the number of columns contained in the receiver. If no TableColumns were created by the programmer, this value is zero, despite the fact that visually, one column of items may be visible. This occurs when the programmer uses the table like a list, adding items but never creating a column.
    Returns:
    the number of columns
    
    Throws:
    SWTException -
    
    ERROR_WIDGET_DISPOSED - if the receiver has been disposed
    
    ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
  - getColumns
```
public TableColumn[] getColumns()
```
    Returns an array of TableColumns which are the columns in the receiver. Columns are returned in the order that they were created. If no TableColumns were created by the programmer, the array is empty, despite the fact that visually, one column of items may be visible. This occurs when the programmer uses the table like a list, adding items but never creating a column.
    Note: This is not the actual structure used by the receiver to maintain its list of items, so modifying the array will not affect the receiver.
    Returns:
    the items in the receiver
    
    Throws:
    SWTException -
    
    ERROR_WIDGET_DISPOSED - if the receiver has been disposed
    
    ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
    See Also:

  - getColumn
```
public TableColumn getColumn(int index)
```
    Returns the column at the given, zero-relative index in the receiver. Throws an exception if the index is out of range. Columns are returned in the order that they were created. If no TableColumns were created by the programmer, this method will throw ERROR_INVALID_RANGE despite the fact that a single column of data may be visible in the table. This occurs when the programmer uses the table like a list, adding items but never creating a column.
    Parameters:
    index - the index of the column to return
    
    Returns:
    the column at the given index
    
    Throws:
    java.lang.IllegalArgumentException -

public void setColumnOrder(int[] order)
```
    Sets the order that the items in the receiver should be displayed in to the given argument which is described in terms of the zero-relative ordering of when the items were added.
    Parameters:
    order - the new order to display the items
    
    Throws:
    SWTException -
    
    ERROR_WIDGET_DISPOSED - if the receiver has been disposed
    
    ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
    java.lang.IllegalArgumentException -

  - getColumnOrder
```
public int[] getColumnOrder()
```
    Returns an array of zero-relative integers that map the creation order of the receiver's items to the order in which they are currently being displayed.
    Specifically, the indices of the returned array represent the current visual order of the items, and the contents of the array represent the creation order of the items.
    Note: This is not the actual structure used by the receiver to maintain its list of items, so modifying the array will not affect the receiver.
    Returns:
    the current visual order of the receiver's items
    
    Throws:
    SWTException -
    
    ERROR_WIDGET_DISPOSED - if the receiver has been disposed

  - setFont
```
public void setFont(Font font)
```
    Description copied from class: Control
    
    Sets the font that the receiver will use to paint textual information to the font specified by the argument, or to the default font for that kind of control if the argument is null.
    
    Overrides:
    
    setFont in class Control
    
    Parameters:
    font - the new font (or null)
  - computeSize
```
public Point computeSize(int wHint,
                int hHint,
                boolean changed)
```
    Description copied from class: Control
    
    Returns the preferred size of the receiver.
    The preferred size of a control is the size that it would best be displayed at. The width hint and height hint arguments allow the caller to ask a control questions such as "Given a particular width, how high does the control need to be to show all of the contents?" To indicate that the caller does not wish to constrain a particular dimension, the constant SWT.DEFAULT is passed for the hint.
    If the changed flag is true, it indicates that the receiver's contents have changed, therefore any caches that a layout manager containing the control may have been keeping need to be flushed. When the control is resized, the changed flag will be false, so layout manager caches can be retained.
    
    Overrides:
    
    computeSize in class Composite
    
    Parameters:
    wHint - the width hint (can be SWT.DEFAULT)
    hHint - the height hint (can be SWT.DEFAULT)
    changed - true if the control's contents have changed, and false otherwise
    
    Returns:
    the preferred size of the control.
    See Also:
    Layout, Control.getBorderWidth(), Control.getBounds(), Control.getSize(), Control.pack(boolean), "computeTrim, getClientArea for controls that implement them"
  - changed
```
public void changed(Control[] changed)
```
    Description copied from class: Composite
    
    Clears any data that has been cached by a Layout for all widgets that are in the parent hierarchy of the changed control up to and including the receiver. If an ancestor does not have a layout, it is skipped.
    
    Overrides:
    
    changed in class Composite
    
    Parameters:
    changed - an array of controls that changed state and require a recalculation of size
