Class 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.

    • Constructor Detail

      • 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:
        java.lang.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

        public <T> T getAdapter​(java.lang.Class<T> adapter)
        Description copied from class: Widget
        Implementation of the Adaptable interface.

        IMPORTANT: This method is not part of the RWT public API. It is marked public only so that it can be shared within the packages provided by RWT. It should never be accessed from application code.

        Specified by:
        getAdapter in interface Adaptable
        Overrides:
        getAdapter in class Composite
        Parameters:
        adapter - the lookup class
        Returns:
        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

      • 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 int indexOf​(TableColumn tableColumn)
        Searches the receiver's list starting at the first column (index 0) until a column is found that is equal to the argument, and returns the index of that column. If no column is found, returns -1.
        Parameters:
        tableColumn - the search column
        Returns:
        the index of the column

        Parameters:
        order - the new order to display the items
        Throws:
        SWTException -
        • ERROR_WIDGET_DISPOSED - if the receiver has been disposed

        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 -

      • 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:
        SWTException -
        • ERROR_WIDGET_DISPOSED - if the receiver has been disposed

        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

        Adds the listener to the collection of listeners who will be notified when the receiver's selection changes, 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 SWT.CHECK style set 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.

      • computeSize

        public Point computeSize​(int wHint,

                                 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.

        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
