Make a TextArea grow with TextHeight in JavaFX (Rows/Lines)

I have been trying to make the TextArea grow with its content, for exmaple:

There is one Line in the Text area, now the user keeps writing and reaches the TextArea's right border and the text wraps, now he does have a second line (which is not wrapped by simply using '\n' internally) and I now want the text field to grow for the height of one more line.

What I have tried already:

This

Text text = textArea.lookup(".text").getLocalBounds.getHeight()

always returns the same, no matter how much Lines i do have.

This

textArea.getPrefRowCount()

always returns

1

no matter how much lines I have.

How can I achieve this? If someone wants a working example, Skype has that kind of mechanism in its chat.

Solution

  • This

    Text text = (Text) textArea.lookup(".text");
textArea.setPrefHeight(text.boundsInParentProperty().get().getMaxY());

    works but is not very nice since the scroll bars keep bugging.
