how do I preselect a row in Jtable / JScrollPane?
Hi
I want to preselect and show a row in a table of e.g. 1000 rows.
e.g. if I type in a value in a field, I want the table to automatically scroll, and show the row whose 1st column has a value that corresponds closest to what I typed.
I tried JTable.setRowSelectionInterval(i,j), but this only highlighted the row, and I had to scoll down the scollpane manually to find it.
Anyone have a suggestion?
regards
Arne

JViewport has a method setViewPosition(p) that takes point p which will be viewport's top left corner. Since u know which row u want to select, getCellRect(row, column) ot JTable gives you cell's Rectangle. Take x and y from this rectangle create a point and use it in setViewPosition. getParent() of JTable directly returns u JViewport. so the code should be
JTable tabl;
/* table code
and finding row and column to be set as r and c;
*/
Rectangle ret = tabl.getCellRect(r,c,true);
Point p = new Point(ret.x,ret.y);
((JViewport)tabl.getParent()).setViewPosition(p);
Hope this helps.
