JFace和FieldEditor

Question

From Eclipse RCP, I'm building a preference page using Field Editors ( http://www.eclipse.org/articles/Article-Field-Editors/field_editors.html )

I'm trying to use the field editor BooleanFieldEditor, subclass of FieldEditor.

My issue is that in the javadoc, I don't find the function to change the state (checked/unchecked) of this field editor.

Where is the setChecked(boolean) function? :-) I missed something?

Answer 1

You do it by accessing the preference store's APIs.

getPreferenceStore().setValue(preferenceID, value);

where is the name of the boolean preference
(ie new BooleanFieldEditor(preferenceID, label, parent); ), and the is true/false .

You get the current value for the ID with

getPreferenceStore().getBoolean(preferenceID);

Answer 2

由于此控件正在管理首选项，因此我建议使用首选项初始化程序 。
