问题描述
我正在尝试在我正在开发的Eclipse RCP应用程序中添加一个RadioGroupFieldEditor，但似乎无法做两件事：
I'm trying to add a RadioGroupFieldEditor in an Eclipse RCP application I'm developing, but seem unable to do two key things:
- 设置单选按钮的值（即打开对话框/窗口时，我想将默认值设置为button1）
- 获取当前值选定的单选按钮（即用户选择的内容，或者如果未设置任何内容，则为上面设置的默认值）。
我使用的代码如下：
String[][] radioButtonOptions = new String[][] { { "Button1" "button1" },
{ "Button2" "button2" } };
RadioGroupFieldEditor radioButtonGroup
= new RadioGroupFieldEditor("PrefValue", "Choose Button1 or Button2", 2,
radioButtonOptions, parent, true)
我有一个fireValueChanged（）方法，我可以用它来设置另一个带有该值的String变量（当用户做出选择时），但是这看起来很乱。它也不允许我设置默认值...
I have a fireValueChanged() method, which I could use to set another String variable with the value (when the user makes a choice), but this just seems messy. It also won't allow me to set the default value...
我怀疑我遗漏了一些重要的东西！是否应该有上述的get / set方法？
I suspect I'm missing something significant! Should there be get/set methods for the above?
推荐答案
由于此控件正在首选项上运行，因此您可以设置默认值在您的首选项初始化程序中。
Since this control is operating on preferences, you can set the default value in your preference initializer.
要获取控件的值，您可以通过getRadioBoxControl（Composite）方法gt实际无线电控件并查询该对象。不是最干净的方式，但它确实有效。
To get the value of the control, you could gt the actual radio control via the getRadioBoxControl(Composite) method and query that object. Not the cleanest way, but it does work adequately.
