Class Table

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:
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 normally make sense to add Control children to it, or set a layout on it, unless implementing something like a cell editor.

Styles:
SINGLE, MULTI, CHECK, FULL_SELECTION, HIDE_SELECTION, VIRTUAL, NO_SCROLL, NO_SEARCH
Events:
Selection, DefaultSelection, SetData, MeasureItem, EraseItem, PaintItem

Note: Only one of the styles SINGLE, and MULTI may be specified.

IMPORTANT: This class is not intended to be subclassed.

  • Constructor Details

    • Table

      public Table(Composite parent, int style)
      Constructs a new instance of this class given its parent and a style value describing its behavior and appearance.

      The style value is either one of the style constants defined in class SWT which is applicable to instances of this class, or must be built by bitwise OR'ing together (that is, using the int "|" operator) two or more of those SWT style constants. The class description lists the style constants that are applicable to the class. Style bits are also inherited from superclasses.

      Parameters:
      parent - a composite control which will be the parent of the new instance (cannot be null)
      style - the style of control to construct
      Throws:
      IllegalArgumentException -
      • ERROR_NULL_ARGUMENT - if the parent is null
      SWTException -
      • ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the parent
      • ERROR_INVALID_SUBCLASS - if this class is not an allowed subclass

    • checkSubclass

      protected void checkSubclass()
      Description copied from class: Widget
      Checks that this class can be subclassed.

      The SWT class library is intended to be subclassed only at specific, controlled points (most notably, Composite and Canvas when implementing new widgets). This method enforces this rule unless it is overridden.

      IMPORTANT: By providing an implementation of this method that allows a subclass of a class which does not normally allow subclassing to be created, the implementer agrees to be fully responsible for the fact that any such subclass will likely fail between SWT releases and will be strongly platform specific. No support is provided for user-written classes which are implemented in this fashion.

      The ability to subclass outside of the allowed SWT classes is intended purely to enable those not on the SWT development team to implement patches in order to get around specific limitations in advance of when those limitations can be addressed by the team. Subclassing should not be attempted without an intimate and detailed understanding of the hierarchy.

      Overrides:
      checkSubclass in class Composite

    • addSelectionListener

      public void addSelectionListener(SelectionListener listener)
      Adds the listener to the collection of listeners who will be notified when the user changes the receiver's selection, by sending it one of the messages defined in the SelectionListener interface.

      When widgetSelected is called, the item field of the event object is valid. If the receiver has the SWT.CHECK style and the check selection changes, the event object detail field contains the value SWT.CHECK. widgetDefaultSelected is typically called when an item is double-clicked. The item field of the event object is valid for default selection, but the detail field is not used.

      Parameters:
      listener - the listener which should be notified when the user changes the receiver's selection
      Throws:
      IllegalArgumentException -
      • ERROR_NULL_ARGUMENT - if the listener is null
      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:

    • calculateWidth

      int calculateWidth(long column, long iter)

    • clear

      public void clear(int index)

    • 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:
      IllegalArgumentException -
      • ERROR_INVALID_RANGE - if the index is not between 0 and the number of elements in the list minus 1 (inclusive)

      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

    • getColumnTypes

      long[] getColumnTypes(int columnCount)

    • 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

      See Also:

    • 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:

    • getHeaderHeight

      public int getHeaderHeight()
      Returns the height of the receiver's header
      Returns:
      the height of the header or zero if the header is not visible
      Throws:

    • getHeaderVisible

      public boolean getHeaderVisible()
      Returns true if the receiver's header is visible, and false otherwise.

      If one of the receiver's ancestors is not visible or some other condition makes the receiver not visible, this method may still indicate that it is considered visible even though it may not actually be showing.

      Returns:
      the receiver's header's visibility state
      Throws:
      SWTException -
      • ERROR_WIDGET_DISPOSED - if the receiver has been disposed

    • getItem

      public TableItem getItem(int index)
      Returns the item at the given, zero-relative index in the receiver. Throws an exception if the index is out of range.
      Parameters:
      index - the index of the item to return
      Returns:
      the item at the given index
      Throws:
      IllegalArgumentException -
      • ERROR_INVALID_RANGE - if the index is not between 0 and the number of elements in the list minus 1 (inclusive)
      SWTException -
      • ERROR_WIDGET_DISPOSED - if the receiver has been disposed
      • ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver

    • getItem

      public TableItem getItem(Point point)
      Returns the item at the given point in the receiver or null if no such item exists. The point is in the coordinate system of the receiver.

      The item that is returned represents an item that could be selected by the user. For example, if selection only occurs in items in the first column, then null is returned if the point is outside of the item. Note that the SWT.FULL_SELECTION style hint, which specifies the selection policy, determines the extent of the selection.

      Parameters:
      point - the point used to locate the item
      Returns:
      the item at the given point, or null if the point is not in a selectable item
      Throws:
      IllegalArgumentException -
      • ERROR_NULL_ARGUMENT - if the point is null
      SWTException -

    • getItems

      public TableItem[] getItems()
      Returns a (possibly empty) array of TableItems which are the items in the receiver.

      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:

      void propagateDraw(long container, long cairo)
      Description copied from class: Composite

      Propagates draw events from a parent container to its children using gtk_container_propagate_draw(). This method only works if the fixedHandle has been connected to the "draw" signal, and only propagates draw events to other siblings of handle (i.e. other children of fixedHandle, but not handle itself).

      It's useful to propagate draw events to other child widgets for things like Table/Tree editors, or other scenarios where a widget is a child of a non-standard container widget (i.e., not a direct child of a Composite).

      Overrides:
      propagateDraw in class Composite
      Parameters:
      container - the parent container, i.e. fixedHandle
      cairo - the cairo context provided by GTK

    • dispose

      public void dispose()
      Description copied from class: Widget
      Disposes of the operating system resources associated with the receiver and all its descendants. After this method has been invoked, the receiver and all descendants will answer true when sent the message isDisposed(). Any internal connections between the widgets in the tree will have been removed to facilitate garbage collection. This method does nothing if the widget is already disposed.

      NOTE: This method is not called recursively on the descendants of the receiver. This means that, widget implementers can not detect when a widget is being disposed of by re-implementing this method, but should instead listen for the Dispose event.

      Overrides:
      dispose in class Widget
