  - resizeTo
```
public void resizeTo(int width,
                     int height)
```
    This is called to change the width and height values. It is always called when the Control gets resized so you can override it to react to a resizing of a Control.
    
    Overrides:
    
    resizeTo in class TableControl
  - getTreeTableModel
```
public TreeTableModel getTreeTableModel()
```
  - getSelectedCell
```
public Point getSelectedCell(Point dest)
```
    Description copied from class: TableControl
    
    This returns a single selected cell. It will work for TreeControls as well as TableControls. It will return null if no cell is selected.
    
    Overrides:
    
    getSelectedCell in class TableControl
  - setData
```
public void setData(Object data)
```
  - scrollToVisible
```
public boolean scrollToVisible(int index)
```
    Ensure that the specified index is visible but do not do a repaint or update.
    
    Parameters:
    
    index - the index of the line to make visible.
    
    Returns:
    
    true if a scroll was done which would require an update() to be done, false if no scroll was done.
  - scrollAndRepaint
```
public void scrollAndRepaint(int sx,
                             int sy,
                             int sw,
                             int sh,
                             int destX,
                             int destY)
```
    Description copied from class: Control
    
    This is called to update a Control on-screen after it has been scrolled. In this case "being scrolled" means that the internal display co-ordinates of the Control have been altered but a repaint has not been done. This method attempts to do the most effecient repaint depending on the capabilities of the underlying graphics system.
    If data can be moved directly on screen, then this will be done and only the newly exposed portion will be updated via a repaintNow() operation. If no moving is possible at all - or if the SIP may be covering the control then no scrolling will be done.
    
    Overrides:
    
    scrollAndRepaint in class Control
    
    Parameters:
    
    sx - The source x co-ordinate.
    
    sy - The source y co-ordinate.
    
    sw - The source width.
    
    sh - The source height.
    
    destX - The destination x co-ordinate.
    
    destY - The destination y co-ordinate.
  - penPressed
```
public void penPressed(Point p)
```
    Description copied from class: Control
    
    Called when the Pen or Mouse button is pressed on the control. This is called by the onPenEvent(PenEvent ev) method.
    Within this method you can use the Control.Gui.currentPenPress() value to find out more about the PenEvent that caused this - including any modifiers (e.g. SHIFT keys) or determine if the left or right mouse button was pressed.
    
    Overrides:
    
    penPressed in class TableControl
    
    Parameters:
    
    p - The point on the Control where the pen was pressed.
  - getDataToDragAndDrop
```
public boolean getDataToDragAndDrop(DragContext dc)
```
    Description copied from class: Control
    
    A quick way to provide DragAndDrop data. This will be called from tryDragAndDrop() which itself may be called from the startDragging() method.
    To setup the DragContext you should set the dataToDrag, isMultiple and isCopy and (optionally) the dragCursor value.
    
    Overrides:
    
    getDataToDragAndDrop in class Control
    
    Parameters:
    
    dc - the DragContext to setup for the drag and drop operation.
    
    Returns:
    
    true if the data was successfully provided to drag and drop in the DragContext. false if there is no data to drag.
  - penDoubleClicked
```
public void penDoubleClicked(Point p)
```
    Description copied from class: Control
    
    Called if the Pen or Mouse button is double clicked on the Control. This is called by the onPenEvent(PenEvent ev) method.
    Within this method you can use the Control.Gui.currentPenPress() value to find out more about the PenEvent that caused this - including any modifiers (e.g. SHIFT keys) or determine if the left or right mouse button was pressed.
    By default this method simply calls the penClicked() method.
    
    Overrides:
    
    penDoubleClicked in class TableControl
    
    Parameters:
    
    p - The point on the Control where the pen was double-clicked.
  - penClicked
```
public void penClicked(Point p)
```
    Description copied from class: Control
    
    Called if the Pen or Mouse button is quickly pressed and released. This is called by the onPenEvent(PenEvent ev) method.
    Within this method you can use the Control.Gui.currentPenPress() value to find out more about the PenEvent that caused this - including any modifiers (e.g. SHIFT keys) or determine if the left or right mouse button was pressed.
    By default this method simply calls the penReleased() method.
    
    Overrides:
    
    penClicked in class TableControl
    
    Parameters:
    
    p - The point on the Control where the pen was clicked.
  - penReleased
```
public void penReleased(Point p)
```
    Description copied from class: Control
    
    Called when the Pen or Mouse button is released on the control. This is called by the onPenEvent(PenEvent ev) method.
    Within this method you can use the Control.Gui.currentPenPress() value to find out more about the PenEvent that caused this - including any modifiers (e.g. SHIFT keys) or determine if the left or right mouse button was pressed.
    
    Overrides:
    
    penReleased in class TableControl
    
    Parameters:
    
    p - The point on the Control where the pen was released.

                                        int y)
```
    Description copied from class: Control
    
    If this returns true then the Pen Hold Down indicator will be displayed before a Popup menu is shown.
    
    Overrides:
    
    showHoldDownIndicator in class TableControl
    
    Parameters:
    
    x - the x position on the Control.
    
    y - the y position on the Control.
    
    Returns:
    
    true if the Control wants the Pen Hold Down indicator shown.
  - doMenu
```
public boolean doMenu(Point where)
```
    Description copied from class: Control
    
    This is a request to display a menu based on the pen being held or the mouse being right clicked on the Control. By default this method calls tryStartMenu(p);
    
    Overrides:
    
    doMenu in class TableControl
    
    Parameters:
    
    where - The point where the pen was pressed or held.
    
    Returns:
    
    true if a menu was displayed.

```
    Description copied from class: Control
    
    This tells the control that data is being removed from it either via a cut operation or by a drag operation that is not explicitly a copy operation. If the object is a Selectable object, then by default this will call delete selection. If you want more advanced operations (e.g. graying out the selection) you need to override this. If DragContext is null, it implies that it is via a "cut" operation, otherwise it is via a drag.
