线路完成后，如何自动将文本区域文本转到下一行？

Question

This is my code for text field. It is not changing the line when the line ends, but continues to go on, making the frame look weird.

I tried to use a scroll pane, but it did not help me.

JTextArea TextArea = new JTextArea(7,10);
gridConstraints.gridx = 0;
gridConstraints.gridy = 0;
TextPanel.add(TextArea, gridConstraints);
TextArea.setEditable(true); 

Answer 1

Without line & word wrapping, the size of a JTextArea will grow beyond its original size. You could call:

textArea.setLineWrap(true);
textArea.setWrapStyleWord(true);

---

Side notes:

• JTextArea are typically placed in JScollPane containers to facilitate scrolling.
• Java naming conventions indicate that variables start with a lowercase letter, making TextArea textArea

Answer 2

I can provide a solution if you are using SceneBuilder.

Select the TextArea-element from the hierarchy-tree, go to "Inspector", select the tab "Properties" and activate "Wrap Text".

Then, every text within the TextArrea-element will have a return at the end of the line.
