Set caret position in javafx.scene.control.TextArea and javafx.scene.control.TextField

Question

I need to set the caret position manually in my code. There is a getCaretPosition() under javafx.scene.control.TextInputControl but there is no setter method.

How can I set the caret position?

TextArea ta = new TextArea();
ta.setText("1234567890");
ta.positionCaret(4);

positionCaret()... what a confusing name for that method. – ceklock Feb 24 '14 at 03:10

yep, smth like `setCaretPosition` would be convenient – Sergey Grinev Feb 24 '14 at 05:02
There's pretty strange behaviour in TextArea, like the down arrow doesn't move down. – brian Jun 11 '14 at 14:45

You can use the positionCaret function as mentioned before. But make sure to wrap it in Platform.runLater. Otherwise it might not work at all.

Platform.runLater( new Runnable() {
    @Override
    public void run() {
        textArea.positionCaret( 0 );
    }
});

There are two method in TextInputControl that allow manipulation of caret position. These are :-

selectPositionCaret(int pos) - Selects the text between the last caret position up to the current caret position that you entered.
positionCaret(int pos) - Sets the current caret position clearing the previous selection as well.

So i think in your case you want to use the positionCaret method to set the position without any selections.

if you want to add it at the end of your TextField you can do the next

TextFieldName.positionCaret(TextFieldName.getText().length());

this will add the Curser at The end .
