带有双显示器的 Java 全屏 jframe

Question

我的问题是，我有 2 个 Jframe，一个用于控制，一个用于向公众展示内容。我需要显示框架全屏显示以避免公众看到它不需要的东西，我需要控制框架在另一个屏幕上可用以控制显示框架。

这是我的问题，今天，我在 Ubuntu 和双屏模式下以这种方式工作没有问题，但是，在 Windows 7 商业 64 中(还没有尝试其他版本)显示框架实际上是全屏的，但是当我单击显示框(包括控制框)以外的任意位置，显示框自动最小化。我猜这是 Windows 最小化最大化行为的问题，但我真的很想让它工作。我知道一个非常肮脏的解决方法，包括使显示框架与我的屏幕大小相同，并将显示框架定位在合适的坐标上。

这是我所做的示例代码。
要全屏显示显示框，请聚焦控制框并按 F11 键。或使用菜单(法语)

GameFrame.java 相当于显示帧

编辑1:
我尝试全屏显示两个窗口，但是当调用文件选择器时，焦点会丢失，因为全屏窗口的行为总是在最前面。

编辑 2:
我还尝试在图标化显示 jframe 上放置一个监听器，但是如果我尝试将状态更改为正常，则显示 jframe 请求焦点，并且我的第二个框架无法使用，因为它失去了焦点

编辑 3:
如果显示框架不是全屏显示，则在单击控制框架时它不会最小化。

Answer 1

所以在这里我自己解决我自己的问题，我最终使用的解决方法，我认为是我能找到的唯一不那么丑陋的解决方法是使用这段代码

private void jmiFullscreenActionPerformed(java.awt.event.ActionEvent evt) {                                              
     GraphicsDevice gd = this.gameFrame.getGraphicsConfiguration().getDevice();

    if (!this.gameFrame.isResizable() ) {
        //gd.setFullScreenWindow(null);
        this.gameFrame.setResizable(true);
        this.gameFrame.setPreferredSize(new Dimension(400, 300));
    } else {
        this.gameFrame.setResizable(false);
        this.gameFrame.setPreferredSize(new Dimension(gd.getDefaultConfiguration().getBounds().getSize()));
        this.gameFrame.setExtendedState(Frame.MAXIMIZED_BOTH);
    }
    refresh();
}           

而不是我原来的例子中的这个

private void jmiFullscreenActionPerformed(java.awt.event.ActionEvent evt) {
    GraphicsDevice gd = this.gameFrame.getGraphicsConfiguration().getDevice();

    if (gd.getFullScreenWindow() != null) {
        gd.setFullScreenWindow(null);
        this.gameFrame.setResizable(true);
        this.gameFrame.setPreferredSize(new Dimension(400, 300));
    } else {
        this.gameFrame.setResizable(false);
        this.gameFrame.setPreferredSize(new Dimension(gd.getDefaultConfiguration().getBounds().getSize()));
        this.gameFrame.enableInputMethods(false);
        gd.setFullScreenWindow(this.gameFrame);
    }
    refresh();
}

所以最后我没有使用 java 全屏功能，我只是使用我的 jframe 的一些属性让它看起来像一个全屏框架。

希望对大家有所帮助!!祝你有美好的一天
