Partial visibility of rows in Jtable

Question

Hi ,
I have created a JTable and added it to the scrollpane as
viewport v= scrollpane.getViewport();
v.setSize(300,300)
v.add(table);
i have some 60 rows to be displayed .
Initially when the table is shown , it is showing 19 rows (0 to 18)
and 19 th row is partly shown .but i want even the 19th row to be shown completely .
I am multiplying 19* table.getRowHeight() ,this gives the height required for 19 rows
this i am setting it to viewport height , but still the 19 the row is not fully shown
here is the code
JViewport parent = (JViewport)table.getParent();
if(parent!=null)
Rectangle pos = parent.getViewRect();
Rectangle bounds = pos.getBounds();
//height should accomadate all 19 rows
int height = 19*getRowHeight();
//width will be same as before
int width = new Double( bounds.getWidth()).intValue();
//create a new dimension and set to the view
parent.setViewSize(new Dimension(width,height));
If i am not clear ,let me know please.

Answer 1

... use ...
Rectangle cellRect = getCellRect(0, 0, true);
// then cellRect.height * 19;

OR
(getRowHeight() + getRowMargin()) * 19
