                 boolean alwaysCenterCursor)
```
    Sets the cursor to the given Field location and attempts to show that location in the center of the screen.
    
    Parameters:
    
    index - the index of the line to go to.
    
    fieldNum - the field on the line to go to.
    
    row - the row in the field to go to.
    
    col - the column in the field to go to.
    
    alwaysCenterCursor - if true, centers cursor on screen. Otherwise, only centers cursor if cursor is offscreen.

protected void goTo(java.math.BigInteger index,
                    int fieldNum,
                    int row,
                    int col,
                    boolean alwaysCenterCursor,

```
  - takeFocus
```
public void takeFocus()
```
    Tell the panel to grab the keyboard input focus.
  - positionCursor
```
public void positionCursor(int offset)
```
    Scrolls the view so that the cursor is at the given offset from the top of the screen
    
    Parameters:
    
    offset - the pixel distance from the top of the screen at which to scroll the display such that the cursor is at that offset.
  - isStartDragOK
```
public boolean isStartDragOK()
```
  - setSelectionColor
```
public void setSelectionColor(java.awt.Color color)
```
    Sets the selection color
    
    Parameters:
    
    color - the color to use for selection.
  - setHighlightColor
```
public void setHighlightColor(java.awt.Color color)
```
    Sets the highlight color
    
    Parameters:
    
    color - the color to use for highlights.
  - getViewerPosition
```
public ViewerPosition getViewerPosition()
```
    Returns a ViewerPosition object which contains the top of screen information. The ViewerPosition will have the index of the layout at the top of the screen and the yPos of that layout. For example, if the layout is completely displayed, yPos will be 0. If part of the layout is off the top off the screen, then yPos will have a negative value (indicating that it begins above the displayable part of the screen.
  - setViewerPosition
```
public void setViewerPosition(java.math.BigInteger index,
                              int xPos,
                              int yPos)
```
    Scrolls the display to show the layout specified by index at the vertical position specified by yPos. Generally, the index will be layout at the top of the screen and the yPos will be <= 0, meaning the layout may be partially off the top of the screen.
    
    Parameters:
    
    index - the index of the layout to show at the top of the screen.
    
    yPos - the position to show the layout.
  - getLayoutModel
```
public LayoutModel getLayoutModel()
```
  - setLayoutModel
```
public void setLayoutModel(LayoutModel model)
```
    Sets the layout model for this field panel
    
    Parameters:
    
    model - the layout model to use.
  - dataChanged
```
public void dataChanged(java.math.BigInteger start,
                        java.math.BigInteger end)
```
    Description copied from interface: LayoutModelListener
    
    Called when the data at an index or range of indexes changes.
    
    Specified by:
    
    dataChanged in interface LayoutModelListener
    
    Parameters:
