Problem with selection in JTable

[Patrik Nilsson]

Hi,

I am having a problem that I hope someone can help me with.

I have a JTable with products and wants to select the last chosen product when I get back to the page containing the table.
To select the productobject I have created my own renderer that draws a border around the product when it is selected.

I use aProductTable.changeSelection(vRow, vCol, false, false); and it scrolls to the right position but it never draws it as selected(with a border).
If I add a sleep(1) before changing selection it draws the border so it seems to have something to do with the table not being fully painted yet or something similar.

I check that I draw in the EDT.

Any help greatly appreciated

if it works OK with a sleep(1), try it like this

SwingUtilities.invokeLater(new Runnable(){
public void run(){
aProductTable.changeSelection(vRow, vCol, false, false);
}
});

depending on the scope of vRow and vCol, they may need to be 'final'

I have that already, I thought that should work that's why I am confused.

It is really hard to put some meaningful code exampel here so I am looking for a general tip what could be wrong but maybe that's too hard to guesss without some code.

Here is a part of my code at least:

private void selectAndScrollToProduct(Product pProduct)
{
ProductTableModel vTableModel =
(ProductTableModel) aProductTable.getModel();
int vIndex = vTableModel.findSelectedIndex(pProduct, aProductTable);
final int vColumns = aProductTable.getModel().getColumnCount();
final int vRow = vIndex / vColumns;
final int vCol = vIndex % vColumns;
aProductTable.setColumnSelectionAllowed(true);
aProductTable.setRowSelectionAllowed(true);
SwingUtilities.invokeLater(new Runnable()
{
public void run()
{
aProductTable.changeSelection(vRow, vCol, false, false);
}
});
aProductTable.validate();
aProductTable.repaint();
}
