我第一次使用JFace MasterDetailsPart時遇到了一些麻煩。詳細信息頁面未顯示 - 當我選擇一個新項目時，該事件未被觸發。 我找不到任何好的示例或教程，甚至JavaDoc也無法幫助我。JFace MasterDetailsPart - 細節頁面未顯示
的detailspart只是實現IDetailsPart和SYSOUT的，當它被初始化消息（其被示出），但標籤未顯示：這裏是DetailsPart碼：
public class Einzelansicht implements IDetailsPage{
public Einzelansicht() {
// TODO Auto-generated constructor stub
}
@Override
public void commit(boolean arg0) {
// TODO Auto-generated method stub
}
@Override
public void dispose() {
// TODO Auto-generated method stub
}
@Override
public void initialize(IManagedForm arg0) {
System.out.println("initialize");
}
@Override
public boolean isDirty() {
// TODO Auto-generated method stub
return false;
}
@Override
public boolean isStale() {
// TODO Auto-generated method stub
return false;
}
@Override
public void refresh() {
// TODO Auto-generated method stub
}
@Override
public void setFocus() {
// TODO Auto-generated method stub
}
@Override
public boolean setFormInput(Object arg0) {
// TODO Auto-generated method stub
return false;
}
@Override
public void selectionChanged(IFormPart arg0, ISelection arg1) {
System.out.println("!!");
}
@Override
public void createContents(Composite arg0) {
arg0.setLayout(new GridLayout());
Label label = new Label(arg0, 0);
label.setText("Einzel");
}
}
相當直接的，我猜，這裏沒什麼特別的，應該失敗。現在我MasterDetaislBlock：
public class BlockZwei extends MasterDetailsBlock {
private FormToolkit toolkit;
private IManagedForm form;
/**
* Create the master details block.
*/
public BlockZwei() {
// Create the master details block
}
/**
* Create contents of the master details block.
*
* @param managedForm
* @param parent
*/
@Override
protected void createMasterPart(final IManagedForm managedForm,
Composite parent) {
toolkit = managedForm.getToolkit();
//
form = managedForm;
final TableViewer tableViewer = new TableViewer(parent);
ArrayContentProvider arrayContent = ArrayContentProvider.getInstance();
tableViewer.setContentProvider(arrayContent);
String[] strings = new String[] { "Eins", "Zwei" };
tableViewer.setInput(strings);
tableViewer
.addSelectionChangedListener(new ISelectionChangedListener() {
@Override
public void selectionChanged(SelectionChangedEvent arg0) {
managedForm.fireSelectionChanged(detailsPart, arg0.getSelection());
}
});
}
/**
* Register the pages.
*
* @param part
*/
@Override
protected void registerPages(DetailsPart part) {
part.registerPage(Einzelansicht.class, new Einzelansicht());
}
正如你所看到的，我註冊了一個監聽器的選擇，而據我瞭解事件應該觸發對detailspage一個事件。 最後但並非最不重要的，我與MDB
public class View extends ViewPart {
public static final String ID = "EclipseRCPStinkt.view";
/**
* This is a callback that will allow us to create the viewer and initialize
* it.
*/
public void createPartControl(Composite parent) {
ManagedForm managed = new ManagedForm(parent);
BlockZwei block = new BlockZwei();
block.createContent(managed);
managed.refresh();
}
/**
* Passing the focus request to the viewer's control.
*/
public void setFocus() {
}
}
ViewPart時難道我忘了叫什麼？我真的找不到我的錯誤
