The realization of the Jscrollpanel scroll bar automatic sliding to the bottom part

1. When Jscrollpanel is used with jtable, there are two ways to add the following code to the listener, which is always at the bottom when you add a row to the table:

   Method 1 (This method works fine):

int rowCount = Tbllogstate.getrowcount ();    Tbllogstate.getselectionmodel (). setSelectionInterval (RowCount-1, rowCount-1);    Rectangle rect = tbllogstate.getcellrect (rowCount-1, 0, true);    Tbllogstate.updateui (); Tbllogstate.scrollrecttovisible (rect);

Method 2 (The method will appear when the new line interface cannot be refreshed):

Jscrollbar ScrollBar = Sptablestate.getverticalscrollbar (); Scrollbar.setvalue (Scrollbar.getmaximum ());

2. Jscrollpanel when used with JTextArea.

Method (pending test)

int height=10;    Point P = new Point ();    P.setlocation (0,this.jtextarea1.getlinecount () *height); This.jScrollPane1.getViewport (). Setviewposition (P);
