Question

I\'m trying to develop auto complete text, which shows a dropdown of suggestions in tableview popup, and I\'m having an issue of how can I hide the whole header-column of ta

Answer 1

The solution is very simple; after the tableview renders, we can get the table header and make invisible, therefor the table header doesn't have to re-layout when the table view layout changes. To catch table rendering is done, we can use width property change, and hide the table header

Here is the code:

tableView.widthProperty().addListener(new ChangeListener() {
        @Override
        public void changed(ObservableValue ov, Number t, Number t1) {
            // Get the table header
            Pane header = (Pane)tableView.lookup("TableHeaderRow");
            if(header!=null && header.isVisible()) {
              header.setMaxHeight(0);
              header.setMinHeight(0);
              header.setPrefHeight(0);
              header.setVisible(false);
              header.setManaged(false);
            }
        }
    });
