Question

我怀疑插件开发中的FieldEditors的相关用法。我有一个首选项页面，它基本上由一些StringFieldEditors，booleanFieldEditors，RadioGroupFieldEditors等组成。

我面临的问题如下：

我有一个名为“完整详细信息”的booleanFiledEditor。代码如下：

BooleanFieldEditor fullDetails = new BooleanFieldEditor("fullDetails", "Full Details", org.eclipse.swt.SWT.NONE, getFieldEditorParent()); 
addField(fullDetails);

一旦用户检查了这个布尔字段，就应该启用跟随此booleanFieldEditor的StringFieldEditors。否则他们应该保持禁用状态其他StringFieldEditors的代码如下：

StringFieldEditor machineName = new StringFieldEditor("machineName", "Host name", getFieldEditorParent()); 
addField(machineName);

StringFieldEditor ipaddress = new StringFieldEditor("ipaddress", "IP Address", getFieldEditorParent()); 
addField(ipaddress); 

StringFieldEditor cpuinfo = new StringFieldEditor("cpuinfo", "CPU Info", getFieldEditorParent()); 
addField(cpuinfo);

如果有人能就如何做到这一点给出一些指示，将会非常有帮助。

您可以使用布尔字段编辑器的setPropertyChangeListener方法在字段更改时执行操作。类似的东西：

fullDetails.setPropertyChangeListener(new IPropertyChangeListener() {
    @Override
    public void propertyChange(PropertyChangeEvent event) {
        boolean newValue = ((Boolean) event.getNewValue()).booleanValue();

        // Enable/disable other fields

        machineName.setEnabled(newValue, getFieldEditorParent());
        .... other fields ....
    });

启用和禁用FieldEditors
