Multi select in tableView javafx - javafx

Question

I want to multi select row in my TableView. The problem is that my application is a multitouch application, I have not a keyboard, so not a CTRL key.
I have a code follow :
tableViewArticle.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE);
But I want to select a lot of row only with a mouse click. For exemple, when I selected one row, the row change in blue, and if after I select an other row, I have two rows in blue.

You could use a custom event filter for the TableView that handles the selection, if a click happened on a table row:
tableViewArticle.addEventFilter(MouseEvent.MOUSE_PRESSED, evt -> {
Node node = evt.getPickResult().getIntersectedNode();
// go up from the target node until a row is found or it's clear the
// target node wasn't a node.
while (node != null && node != tableViewArticle && !(node instanceof TableRow)) {
node = node.getParent();
}
// if is part of a row or the row,
// handle event instead of using standard handling
if (node instanceof TableRow) {
// prevent further handling
evt.consume();
TableRow row = (TableRow) node;
TableView tv = row.getTableView();
// focus the tableview
tv.requestFocus();
if (!row.isEmpty()) {
// handle selection for non-empty nodes
int index = row.getIndex();
if (row.isSelected()) {
tv.getSelectionModel().clearSelection(index);
} else {
tv.getSelectionModel().select(index);
}
}
}
});
If you want to handle touch events differently to mouse events, you can also use MouseEvent.isSynthesized to check, if the event is a touch event.
