How can a TableView iterate over Rows and get Cells?

Question

I need to iterate over all the rows in a TableView without using Events. I would like to get the total number of rows, the TableRow, and a Cell from a specified TableColumn in the TableRow.
Something like this:
for(TableRow tableRow: tableView.getRows()){
    Cell cell = tableRow.getColumn(4).getCell();
    // do something to the cell
}Is this possible?

Answer 1

However, the problem with the CheckBox has been resolved so I don't need to iterate over the rows any longer.Yep, not using lookups to handle this is a much better solution, I just provided my lookup based solution because you asked for an iterative solution.
The (lookup) code below doesn't produce any output.It works for me, I included an executable sample so you can try it out.
My guess is that you aren't taking into account the fact that the lookup is just a snapshot of the table's cells at a moment in time.
If you do a cell lookup before you show the table on a stage, it's not going to return anything because the cells are only generated on an as needed basis and there is no need to generate any cells before displaying the table on a stage.
I get the following output on Java8b89 Win7:
