为什么我的第二个框架没有被点击显示？

Question

当我点击打开我的第二帧时，它不会出现。但是，如果我选择仅运行相同的帧，它确实会出现（在eclipse中）。我确实有一个听众mntmSetup，并确认它正在被击中。难道我做错了什么？我不明白GUI为什么不显示。

代码：

调用它在我公司主营：

else if (obj == Main.mntmSetup) 
    { 
     TestSetup setup = null; 
    try { 
     setup = new TestSetup(); 
    } catch (ParserConfigurationException 
      | SAXException | IOException e1) { 
     // TODO Auto-generated catch block 
     e1.printStackTrace(); 
    } 
     setup.setVisible(true); 
    } 

TestSetup.java：

public class TestSetup extends JPanel { 
/**

private boolean debug = true, // Prints out debug messages 
       booleanValue; // Used to convert String[] execute to a boolean value

public String[] test_case = xml.CreateTestCasesArray("testcase", "filename"); // Get the test case name from the CLA testsuite.xml 
public String[] iterations = xml.CreateTestCasesArray("testcase", "iterations"); // Get the amount of iterations from the CLA testsuite.xml 
public String[] execute = xml.CreateTestCasesArray("testcase", "execute");  // Get the execute status (true or false) from the CLA testsuite.xml

为了得到像Eclipse的一个第二帧，使TestSetup＃createAndShowGUI public并在您的第一个片段中调用它：

else if (obj == Main.mntmSetup) 
{ 
    try{ 
     TestSetup.createAndShowGUI(); 
    } catch (ParserConfigurationException | SAXException 
        | IOException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
    } 
}
