Java运行时外观

问题描述：

我有一个基本的GUI(带有按钮的纯Jframe)，并且使用Nimrod改变了外观.新的l& f是一个黑暗的主题，我会在运行时更改.

I have a basic GUI (plain Jframe with a button) and I have changed the look and feel using Nimrod. The new l&f is a dark theme which I change at runtime.

但是，当运行GUI时，在很短的时间内，GUI的背景很亮，然后应用了新的深色l& f.

However, when the GUI is run, for a very brief moment, the GUI has a bright background, and then the new dark l&f is then applied.

我认为造成这种短暂的闪烁的原因是在运行时，在应用新的l& f之前短暂地显示了默认的l& f.

I assume what is causing this brief flash of brightness is that at runtime, the default l&f is showing briefly, just before the new one is being applied.

这只是一秒钟的一小部分，但由于看起来很不整洁，所以很明显而且很烦人.

It's only a fraction of a second, but it's noticeable and quite annoying as it looks untidy.

如果我在运行后用按钮更改L& f，似乎不会发生.

It doesn't seem to happen if I change the l&f after runtime with a button.

那么，其他人对此有任何经验吗?有没有可能的解决方法?隐藏JFrame，直到应用新的l& f?

So, does anyone else have any experience with this? Is there a possible workaround for this? Hide the JFrame until the new l&f is applied?

这是我的代码，如果有帮助的话:

Here's my code if that helps:

    public static void main(String[] args) 
    {        
        setTheme();        

        NewJFrame njf = new NewJFrame();
        njf.setLocationRelativeTo(null);
        njf.setTitle("My First Swing Application");
        njf.pack();        
        njf.setVisible(true);                
    }

    static void setTheme()
    {
        NimRODTheme nt = new NimRODTheme();
        nt.setPrimary1( new Color(0,51,153));
        nt.setPrimary2( new Color(0,92,143));
        nt.setPrimary3( new Color(0,102,153));
        nt.setSecondary1( new Color(31,31,31));
        nt.setSecondary2( new Color(41,41,41));
        nt.setSecondary3( new Color(51,51,51));
        nt.setWhite( new Color(0,0,0));
        nt.setBlack( new Color(255,255,255));
        nt.setMenuOpacity(195);
        nt.setFrameOpacity(180);

        NimRODLookAndFeel NimRODLF = new NimRODLookAndFeel();
        NimRODLF.setCurrentTheme (nt);

        try
        {
            UIManager.setLookAndFeel(NimRODLF);       
        }
        catch(Exception e)
        {

        }       

    }

此外，如果需要Nimrod，则可以在此处获取: http://www.mediafire.com/?l9pytbooenmemgc

Also, if nimrod is needed, you can get it here: http://www.mediafire.com/?l9pytbooenmemgc

非常感谢任何帮助.
