为什么Java jFrame setResizable（）很难采取行动？

此代码由Netbean 6.8 GUI构建器自动生成。 默认应用程序未包含在jFrame中！ 它只在jPanel中，我不知道如何使它无法重新resize。 所以我添加了一个jFrame来包含所有这些，尽管我设置了它的setResizable（）; 为假…它仍然重新resize！ 这是代码：

我为长代码道歉，我不确定哪个部分可能对这个案件很重要，哪个部分不重要。

如果你知道这里有什么问题，请告诉我

Answer 1

默认应用程序未包含在jFrame中！ 它只在jPanel中，我不知道如何使它无法重新resize。 所以我添加了一个jFrame

你不应该创建一个额外的JFrame，你的面板已经在一个框架中你应该使用这样的东西而不是创建一个新的框架：

 getFrame().setResizeable(false); 

Answer 2

你的代码有错误; 我简单的自包含测试程序显示setResizable(false)工作得很好：

 package com.businesslink.core.tst.ld.dct; import java.awt.*; import javax.swing.*; public class SwgTestFrame1b extends JFrame { public SwgTestFrame1b() { super("SwgTestFrame1b"); setBackground(Color.white); setResizable(false); pack(); } static public void main(String[] args) { new SwgTestFrame1b().show(); } }

快速搜索您的代码，无法在mainFrame上调用show或setVisible; 看起来您只显示与mainFrame相关的对话框。 现在setResizable只在mainFrame上完成，不会影响任何作为mainFrame子元素的对话框。 它也不会影响FrameView使用的框架。

---

PS，只是FTR，我绝对厌恶不可resize的窗口，它们是GUI工具包或懒惰程序员的标志。

Answer 3

fill code（（java.awt.Frame）root）.setResizable（false）; 在应用程序类中，完全在方法configureWindow中 。 （应用程序类是实例化View类的类。）它应该有所帮助
