Java Swing - 在 JTextPane 中插入组件(JTextArea)的问题 [英] Java Swing - Problem with inseting component(JTextArea) in JTextPane

问题描述

我想在运行时单击按钮在 JTextPane 中添加多个新的 JTextArea.为此，我为 JTextPane 设置了 Box 布局，并使用 mytextpane.add() 方法在其中添加了新组件.但它正在根据布局调整大小和重新定位，并且不会保留我分配的原始大小.此外，当我向其中添加更多组件时，插入的组件会缩小，但我希望在向 JTextPane 添加更多组件时显示滚动条.请帮我解决这个问题.

I want to add multiple new JTextArea in JTextPane at runtime on button click. For that i have set Box layout for my JTextPane and i add new component in that using mytextpane.add() method. but it is getting resized and repositioned depending on layout and does not retain the original size of it which i had assigned. Also as i add more component to it, the inserted components are getting shrinked but i want a scrollbar to show up when i add more components to my JTextPane. Please help me with this problem.

推荐答案

通常您将组件添加到 JPanel，所以我不确定您为什么尝试将它们添加到 JTextPane.基本代码为:

Generally you add components to a JPanel, so I'm not sure why you are attempting to add them to a JTextPane. The basic code is:

panel.add( someComponent );
panel.revalidate();

但是，如果您真的想将它们添加到 JTextPane，那么您应该使用 JTextPane 的 insertComponent() 方法.

However, if you really are trying to add them to a JTextPane then you should be using the insertComponent() method of JTextPane.
