Question

我有一份Eclipse RCP申请,该申请应当通过拖拉机开放档案;从窗户勘探商中删除。因此,我执行了这一规定:

public class ApplicationWorkbenchAdvisor extends WorkbenchAdvisor {

    @Override
    public WorkbenchWindowAdvisor createWorkbenchWindowAdvisor(IWorkbenchWindowConfigurer configurer) {
        configurer.addEditorAreaTransfer(FileTransfer.getInstance());
        configurer.configureEditorAreaDropListener(editorDropListener);
        return new ApplicationWorkbenchWindowAdvisor(configurer);
    }
[...]
}

<代码>DropListener为“代码>DropTargetAdapter,实施<代码>drop()。

现在,如果我从我的探索者手中拿到我的申请,我就会发现,“Windows Un available”会变幻灯,下降不会奏效。 The editorDropListener.drop(.

如果我用CTRL或ALT钥匙接手,我就拿到“窗口拷贝”的 mo。登机工程和editorDropListener.drop()被成功点名。

在什么地方,允许哪一种下降?

Answer 1

It seems this problem has not been solve from above. I just have look up the apis of DND and solve this problem, eliminate the Ctrl or Alt press. Drag and Drop We just need to add some code in you EditorAreaDropAdapter:

        @Override
public void dragEnter(DropTargetEvent event) {
    // TODO Auto-generated method stub
    event.detail = DND.DROP_COPY;
    super.dragEnter(event);
}

详细情况必须定为DND。 DROP_COPY forceptence.

Answer 2

It is a little more complicated than that, as the editor area does not accept a MOVE DND request.

详细情况请见<代码>org.eclipse.ui.internal.ide.EditorAreaDropAdapter。

Answer 3

Use this code in your listener. it will work.

                @Override
        public void dragEnter(final DropTargetEvent event) {

            if (event.detail == DND.DROP_DEFAULT) {
                if ((event.operations & DND.DROP_COPY) != 0) {
                    event.detail = DND.DROP_COPY;
                } else {
                    event.detail = DND.DROP_NONE;
                }
            }
        }
