EclipseRCP 환경설정 페이지 사용하기(EclipseRCP Preference Page)

1. add (org.eclipse.ui.preferencePages)extension to plugin.xml

- plugin.xml파일에 환경설정 확장점을 추가해준다.

2. create new class that implements IWorkbenchPreferencePage

- IWorkbenchPreferencePage를 구현한 클래스를 생성한다.

3. If you need to adjust, you can make Preference constants and Preference initializer classes.

- 필요하다면, 환경설정 상수나, 초기화 클래스관련 클래스를 생성할 수 있습니다.

범위 : 기본, 환경, 인스턴스

scopes : default , configuration , instance

Preference.java

Code:

public class PreferencePage
extends FieldEditorPreferencePage
implements IWorkbenchPreferencePage {
public PreferencePage() {
super(GRID);
setPreferenceStore(Plugin.getDefault().getPreferenceStore());
setDescription("Preferences");
}
	public void createFieldEditors() {
	String[] filterExtension = { "*.file extension" };
	addField(new DirectoryFieldEditor(PreferenceConstants.DIR_PATH,         "&Directory preference:", getFieldEditorParent()));
	FileFieldEditor filePathPrefEditor = new FileFieldEditor(PreferenceConstants.FILE_PATH,
	"&File Path preference:", getFieldEditorParent());
	filePathPrefEditor.setFileExtensions(filterExtension);
	addField(filePathPrefEditor);
	addField(
	new BooleanFieldEditor(
	PreferenceConstants.P_BOOLEAN,
	"&An example of a boolean preference",
	getFieldEditorParent()));
	addField(new RadioGroupFieldEditor(
	PreferenceConstants.P_CHOICE,
	"An example of a multiple-choice preference",
	1,
	new String[][] { { "&Choice 1", "choice1" }, {
	"C&hoice 2", "choice2" }
	}, getFieldEditorParent()));
	addField(
	new StringFieldEditor(PreferenceConstants.P_STRING, "A &text preference:", getFieldEditorParent()));
	}
	/* (non-Javadoc)
	* @see org.eclipse.ui.IWorkbenchPreferencePage#init(org.eclipse.ui.IWorkbench)
	*/
	public void init(IWorkbench workbench) {
	}
	}

PreferenceConstants.java

Code:

public class PreferenceConstants {

public static final String DIR_PATH = "dirPath";

public static final String FILE_PATH = "filePath";

public static final String P_PATH = "pathPreference";

public static final String P_BOOLEAN = "booleanPreference";

public static final String P_CHOICE = "choicePreference";

public static final String P_STRING = "stringPreference";

}

PreferenceInitializer.java

Code:

public class PreferenceInitializer extends AbstractPreferenceInitializer {

public void initializeDefaultPreferences() {

IPreferenceStore store = Plugin.getDefault().getPreferenceStore();

store.setDefault(PreferenceConstants.DIR_PATH,"C:\\Program Files");

}

}

RadioGroupFieldEditor 사용팁

만약 아직 지원하지 않는 값을 사용자가 클릭했을 경우,

다음과 같이 propertyChange를 overriding하여 필드값을 Initializer에서 설정해준 값으로 불러와 변경시키는 방법을 사용 하면된다.

Code:

public void propertyChange(PropertyChangeEvent event) {
super.propertyChange(event);
if(event.getProperty().equals(FieldEditor.VALUE)) {
if(event.getSource() instanceof RadioGroupFieldEditor) {
if(!event.getNewValue().equals("available value")){
Dialog.showWarningMessageDialog(getFieldEditorParent(), "Not available", "Sorry, Now available only for available value.");
RadioGroupFieldEditor radioGroupEditor = (RadioGroupFieldEditor) event.getSource();
radioGroupEditor .loadDefault();
}
	}
	}
	}
