如何在 JOptionPane 上添加文本区域 [英] How to add text area on JOptionPane

问题描述

目前我有一个 JOptionPane.单击按钮时，我正在执行以下行.

Currently I have a JOptionPane. On clicking a button I am executing following line.

JOptionPane.showInputDialog(this,"Enter your message","Messages",2);

它会打开一个带有文本框的弹出窗口.此文本框接受大约 40/50 个字符.事实上，我的要求是在此文本框中接收长消息(最多 300 个字符)，这将阻止此操作.所以我们想在这个输入对话框上想出一个文本区域?有可能吗?有没有更好的解决办法?提前致谢.

It opens a popup with a text box. This text box accepts around 40/50 characters. In fact my requirement is to take long message (upto 300 characters) in this text box which is stopping this. So we want to come up with a text area on this input dialog? Is it possible how? Is there any better solution? Thanks in advance.
