我有问题。
我离开游戏已有一段时间了，并得到了一个朋友的附带项目。他要求我创建一个具有搜索栏，按钮和标签的GUI。
他问我，当用户键入内容并按Enter键时，结果必须显示在下表中。
因此，我启动了Netbeans，并开始使用拖放支持来开始创建GUI。
然后我被卡住了。我需要帮助的是弄清楚如何将它们绑在一起。
这是我到目前为止所拥有的：

请帮助。
答案 0 :(得分：0)
类似的声音，您需要在文本字段上附加一个侦听器
if( previous_form != null)
previous_form.Close();
SomeForm someform = new SomeForm();
previsous_form = some_form;
someform.Show();
您还可以使用更改侦听器来检测文本字段中文本的更改
也要告诉您，JavaFX是Swing的替代产品。不再支持Swing，但它仍然可以正常工作。仅供参考
