 public TRGridBagPanel()

Create a new panel that uses GridBag as its layout manager and provides a number of convenience methods for setting constraints.

 public TRGridBagPanel(int numCols)

This ctr is used for simplier layouts when you want to just call the add(Component) and let us take care of incrementing the placement. We take care of the row and col positioning and lay out the components from left to right.

Parameters:

This ctr is used for simplier layouts when you want to just call the add(Component) and let us take care of incrementing the placement. We take care of the row and col positioning and lay out the components from left to right.

Parameters:

numCols - the number of columns we'll have

mp - if true then we give out insets so we don't hit the edges

See Also:

addNext, fillHorizontal, addSpace, setMainPanel

                      int leftMargin)

Convenience to add a label and a component w/ a left margin. Yes there are too many variations here.

See Also:

addNext

 public void addNext(Component c)

Add to the "next" position. Can't be called add() due to problems conflicting with Container.add();

Parameters:

c - the component to add

 public void addNext(Component c,
                     int leftMargin)

Add to the "next" position with the spacing between this and the previous component added on this line. Can't be called add() due to problems conflicting with Container.add().

Parameters:

c - the component to add

leftMargin - the spacing between the previous component on the line and this one

 public void fillNone()

Let the next component never grow

 public void anchorNorth()

 public void anchorEast()

 public void anchorSouth()

 public void anchorWest()

 public void anchorCenter()

 public void addSpace()

Add some "spacing". Sort of a kludge - we add an empty label that takes up the whole row and we advance to the next row.

 public void addLine()

Add a horizontal line.

 public void addLine2()

Add a horizontal line w/ extra space before and after.

 public void addLabeledLine(String label)
