java - Lanterna-如何创建一个简单的复选框菜单？

Question

到目前为止我已经

Terminal terminal = new DefaultTerminalFactory().createTerminal();
TerminalScreen screen = new TerminalScreen(terminal);
MultiWindowTextGUI mwtg = new MultiWindowTextGUI​(screen);

CheckBoxList checkBoxList = new CheckBoxList<String>();
checkBoxList.addItem("Check one");
checkBoxList.addItem("Check two");

我不知道如何将 checkBoxList 直接添加到 mwtg

非常感谢您的帮助

好吧，在盲目地通过 API 瞎猜几个小时之后，我这样做了，它有效，但可能很笨重或有味道，所以请随意改进我自己的答案。

private MultiWindowTextGUI mwtg;
private BasicWindow bw;
private CheckBoxList<String> checkBoxList;
private List<String> checkedItems;
Terminal terminal = new DefaultTerminalFactory().createTerminal();
TerminalScreen screen = new TerminalScreen(terminal);
MultiWindowTextGUI mwtg = new MultiWindowTextGUI​(screen);
this.checkBoxList = new CheckBoxList<String>();
this.checkBoxList.addItem("item1");
this.checkBoxList.addItem("item2");
this.checkBoxList.addItem("item3");
this.checkBoxList.addListener((sel, prev) ->
    { this.checkedItems = this.checkBoxList.getCheckedItems​(); }
);
Panel panel = new Panel();
panel.setLayoutManager(new GridLayout(4));
panel.addComponent(this.checkBoxList);
Button button = new Button("Done", () -> this.bw.close());
button.addTo​(panel);
this.bw = new BasicWindow("Choices");
this.bw.setComponent(panel);
this.mwtg.addWindowAndWait(this.bw);

我希望这对某人有用......
