How to make text area text automatically go to the next line when line is finished?
提问by akki0996
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.
这是我的文本字段代码。行结束时并没有改变行，而是继续前进，使框架看起来很奇怪。
I tried to use a scroll pane, but it did not help me.
我尝试使用滚动窗格，但它没有帮助我。
JTextArea TextArea = new JTextArea(7,10);
gridConstraints.gridx = 0;
gridConstraints.gridy = 0;
TextPanel.add(TextArea, gridConstraints);
TextArea.setEditable(true);

Without line & word wrapping, the size of a JTextAreawill grow beyond its original size. You could call:
如果没有换行和自动换行，a 的大小JTextArea将超过其原始大小。你可以打电话：
textArea.setLineWrap(true);
textArea.setWrapStyleWord(true);
Side notes:
边注：
JTextAreaare typically placed inJScollPanecontainers to facilitate scrolling.- Java naming conventions indicate that variables start with a lowercaseletter, making
TextAreatextArea
JTextArea通常放置在JScollPane容器中以方便滚动。- Java 命名约定表明变量以小写字母开头，使得
TextAreatextArea

I can provide a solution if you are using SceneBuilder.
如果您使用 SceneBuilder，我可以提供解决方案。
Select the TextArea-element from the hierarchy-tree, go to "Inspector", select the tab "Properties" and activate "Wrap Text".
从层级树中选择 TextArea 元素，转到“检查器”，选择“属性”选项卡并激活“换行文本”。
Then, every text within the TextArrea-element will have a return at the end of the line.
然后，TextArrea 元素中的每个文本都将在行尾返回。
Cheers
干杯
