Codename一次滚动ComponentGroup+手风琴+切换按钮

Question

我有一个表单（带有一个boxlayout.y)，它嵌套了ComponentGroup+手风琴+切换按钮。当用户展开手风琴（在ComponentGroup中）时，切换按钮列表（在手风琴中）很长，它不适合屏幕。

我的问题是如何在所有窗体中启用滚动。

下面的代码是代码结构的示例。实际代码是由我编写的复杂解析器生成的，该解析器从json输入自动生成UI：

Form hi = new Form("Hi World", BoxLayout.y());

// Warning: you need to set the theme property "ComponentGroupBool" to true
Button button1 = new Button("Button 1", "ButtonMenuCategories");
CheckBox button11 = CheckBox.createToggle("Button 1.1");
CheckBox button12 = CheckBox.createToggle("Button 1.2");
Button button13 = new Button("Button 1.3", "ButtonMenuCategories");
CheckBox button131 = CheckBox.createToggle("Button 1.3.1");
CheckBox button132 = CheckBox.createToggle("Button 1.3.2");
CheckBox button133 = CheckBox.createToggle("Button 1.3.3");
CheckBox button14 = CheckBox.createToggle("Button 1.4");
Button button2 = new Button("Button 2", "ButtonMenuCategories");
Button button3 = new Button("Button 3", "ButtonMenuCategories");
Button button4 = new Button("Button 4", "ButtonMenuCategories");
Button button5 = new Button("Button 5", "ButtonMenuCategories");

Accordion accordion13 = new Accordion();
accordion13.addContent(button13, FlowLayout.encloseCenter(ComponentGroup.enclose(button131, button132, button133)));
Accordion accordion1 = new Accordion();
accordion1.addContent(button1, FlowLayout.encloseCenter(ComponentGroup.enclose(button11, button12, accordion13, button14)));
Accordion accordion2 = new Accordion();
accordion2.addContent(button2, new Label("Hello"));
Accordion accordion3 = new Accordion();
accordion3.addContent(button3, new Label("Hello"));
Accordion accordion4 = new Accordion();
accordion4.addContent(button4, new Label("Hello"));
Accordion accordion5 = new Accordion();
accordion5.addContent(button5, new Label("Hello"));

Container menu = FlowLayout.encloseCenter(ComponentGroup.enclose(accordion1, accordion2, accordion3, accordion4, accordion5));

hi.add(menu);
hi.show();

默认情况下，窗体内容窗格是可滚动的，除非您使用setscrollabley（false）显式禁用它。当您设置borderlayout时，这也是隐式地为您完成的。由于您使用了BoxLayout，表单的内容是可滚动的（大多数情况下应该是这样）。

但是，accordion也是可滚动的，这意味着您有两个嵌套的可滚动组件。我很难想象你在这里看到/感受到了什么，但有一个明显的错误，你错过了：

accordion13.setScrollableY(false);
accordion1.setScrollableY(false);
accordion2.setScrollableY(false);
//... etc ...
