Constructor:
 public TableColumn(Table parent,
    int style) 
    Constructs a new instance of this class given its parent (which must be a Table) and a style value describing its behavior and appearance. The item is added to the end of the items maintained by its parent.

    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

    SWT#RIGHT

    exception: IllegalArgumentException -
    • ERROR_NULL_ARGUMENT - if the parent is null

    exception: 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 TableColumn(Table parent,
    int style,
    int index) 
    Constructs a new instance of this class given its parent (which must be a Table), a style value describing its behavior and appearance, and the index at which to place it in the items maintained by its parent.

    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.

    Note that due to a restriction on some platforms, the first column is always left aligned.

    Parameters:
    parent - a composite control which will be the parent of the new instance (cannot be null)
    style - the style of control to construct
    index - the zero-relative index to store the receiver in its parent
    Throws:
    IllegalArgumentException -
    • ERROR_NULL_ARGUMENT - if the parent is null
    • ERROR_INVALID_RANGE - if the index is not between 0 and the number of elements in the parent (inclusive)

    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

    exception: IllegalArgumentException -
    • ERROR_NULL_ARGUMENT - if the parent is null
    • ERROR_INVALID_RANGE - if the index is not between 0 and the number of elements in the parent (inclusive)

    exception: 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

Method from org.eclipse.swt.widgets.TableColumn Detail:
 public  void addControlListener(ControlListener listener) 
    Adds the listener to the collection of listeners who will be notified when the control is moved or resized, by sending it one of the messages defined in the ControlListener interface.
 public  void addSelectionListener(SelectionListener listener) 
    Adds the listener to the collection of listeners who will be notified when the control is selected by the user, by sending it one of the messages defined in the SelectionListener interface.

    widgetSelected is called when the column header is selected. widgetDefaultSelected is not called.

 static int checkStyle(int style) 
 protected  void checkSubclass() 
  void destroyWidget() 
 public int getAlignment() 
    Returns a value which describes the position of the text or image in the receiver. The value will be one of LEFT, RIGHT or CENTER.
 public boolean getMoveable() 
    Gets the moveable attribute. A column that is not moveable cannot be reordered by the user by dragging the header but may be reordered by the programmer.
 String getNameText() 
 public Table getParent() 
    Returns the receiver's parent, which must be a Table.
 public boolean getResizable() 
    Gets the resizable attribute. A column that is not resizable cannot be dragged by the user but may be resized by the programmer.
 public String getToolTipText() 
    Returns the receiver's tool tip text, or null if it has not been set.
 public int getWidth() 
    Gets the width of the receiver.
 public  void pack() 
    Causes the receiver to be resized to its preferred size. For a composite, this involves computing the preferred size from its layout, if there is one.
  void releaseHandle() 
  void releaseParent() 
 public  void removeControlListener(ControlListener listener) 
    Removes the listener from the collection of listeners who will be notified when the control is moved or resized.
 public  void removeSelectionListener(SelectionListener listener) 
    Removes the listener from the collection of listeners who will be notified when the control is selected by the user.
 public  void setAlignment(int alignment) 
    Controls how text and images will be displayed in the receiver. The argument should be one of LEFT, RIGHT or CENTER.

    Note that due to a restriction on some platforms, the first column is always left aligned.

 public  void setImage(Image image) 
  void setImage(Image image,
    boolean sort,
    boolean right) 
 public  void setMoveable(boolean moveable) 
    Sets the moveable attribute. A column that is moveable can be reordered by the user by dragging the header. A column that is not moveable cannot be dragged by the user but may be reordered by the programmer.
 public  void setResizable(boolean resizable) 
    Sets the resizable attribute. A column that is resizable can be resized by the user dragging the edge of the header. A column that is not resizable cannot be dragged by the user but may be resized by the programmer.
  void setSortDirection(int direction) 
 public  void setText(String string) 
 public  void setToolTipText(String string) 
    Sets the receiver's tool tip text to the argument, which may be null indicating that the default tool tip for the control will be shown. For a control that has a default tool tip, such as the Tree control on Windows, setting the tool tip text to an empty string replaces the default, causing no tool tip text to be shown.

    The mnemonic indicator (character '&') is not displayed in a tool tip. To display a single '&' in the tool tip, the character '&' can be escaped by doubling it in the string.

 public  void setWidth(int width) 
    Sets the width of the receiver.
  void updateToolTip(int index)
