Hi,

Can anyone tell me how i can show a specific row as the first one in
the visible area of a JTable.

For example:
I have 100 rows in a JTable but only 10 are shown in the visible area.
At a certain moment i want to make forexample row 23 as the first one
in the visible area of a JTable in a scrollpanel.

Bye

This is what I wrote once:

void showRow(int rowIndex)
{
if (rowIndex >= 0 && rowIndex < myTable.getModel().getRowCount())
{
Rectangle vr = myTable.getVisibleRect();
Rectangle cr = myTable.getCellRect(rowIndex, 0, false);
vr.y = cr.y;
vr.height = cr.height;
myTable.scrollRectToVisible(vr);
}
}
