有什么办法可以从JinternalFrame中调用其他JinternalFrame，但是可以在主Jframe的desktopPane中进行。 [英] is there any way call other JinternalFrame from an JinternalFrame but, in the desktopPane of of main Jframe.

问题描述

下面的代码部分1用于从MDI应用程序中的menuItem调用UcakListesi（JinternalFrame），没有问题。

The "code part 1" below is used for calling UcakListesi(JinternalFrame) from menuItem in MDI application without problem.

我想调用相同的UcakListesi（JinternalFrame） ）从另一个JinternalFrame使用相同的代码，但是，我收到有关 desktopPane.add（nw）;的错误参见代码部分2。无法访问主jframe desktopPane窗体JinternalFrame ..

I would like to call same UcakListesi(JinternalFrame) from another JinternalFrame using same code however, I get error about "desktopPane.add(nw);" line see code part 2. Can't access main jframe desktopPane form JinternalFrame ..

是否可以通过JinternalFrame调用其他JinternalFrame，但是在main的desktopPane中Jframe。

is there any way call other JinternalFrame from an JinternalFrame but, in the desktopPane of of main Jframe.

对不起，我的英语不好。

sorry for my poor english.

致谢，谢谢。

推荐答案

I找到了解决方案。

I found the solution .

用于第一类（MainApplication），其中您的Jframe和JDesktopPane位于下面的位置代码中

for the first class(MainApplication) where your Jframe and JDesktopPane inside place code below

public javax.swing.JDesktopPane getDesktopPane() {
    return desktopPane;
}

然后在像这样的任何JinternalFrame类文件中使用来调用另一个文件（YourJinternalFrame）

then use in any JinternalFrame class file like this to call another one(YourJinternalFrame)

 YourJinternalFrame  nw = YourJinternalFrame.getInstance();
    nw.pack();
    if (nw.isVisible()) {
    } else {
        getDesktopPane().add(nw);
        nw.setVisible(true);
    }
    try {
        nw.setMaximum(true);
    } catch (PropertyVetoException ex) {
        Logger.getLogger(MainApplication.class.getName()).log(Level.SEVERE, null, ex);
    }

仅获取一个名为JinternalFrame的实例
将此代码放在下面在被称为JinternalFrame（YourJinternalFrame）

to get only one instance of called JinternalFrame place this code below in the called JinternalFrame(YourJinternalFrame)

private static YourJinternalFrame myInstance;

public static YourJinternalFrame getInstance() {
    if (myInstance == null) {
        myInstance = new YourJinternalFrame();
    }
    return myInstance;

谢谢：）
