RCP视图昄��位置讄��

Mon, 12 Mar 2012 06:25:00 GMT

在RCP有时候需要将视图攑֜�一边，分上下显�C�，但是在RCP没有RIGHT_TOP和RIGHT_BOTTOM�q�样的方位设�|�，我们可以通过��d��视图的关联ID讄��相对位置。如下代码addView�Ҏ��Q�createFolder也相�?div style="background-color:#eeeeee;font-size:13px;border:1px solid #CCCCCC;padding-right: 5px;padding-bottom: 4px;padding-left: 4px;padding-top: 4px;width: 98%;word-break:break-all">   /**
     * Adds a view with the given compound id to this page layout.
     * See the {@link IPageLayout} type documentation for more details about compound ids.
     * The primary id must name a view contributed to the workbench's view extension point
     * (named "org.eclipse.ui.views").
     *
     * @param viewId the compound view id
     * @param relationship the position relative to the reference part;
     *  one of TOP, BOTTOM, LEFT,
     *  or RIGHT
     * @param ratio a ratio specifying how to divide the space currently occupied by the reference part,
     *    in the range 0.05f to 0.95f.
     *    Values outside this range will be clipped to facilitate direct manipulation.
     *    For a vertical split, the part on top gets the specified ratio of the current space
     *    and the part on bottom gets the rest.
     *    Likewise, for a horizontal split, the part at left gets the specified ratio of the current space
     *    and the part at right gets the rest.
     * @param refId the id of the reference part; either a view id, a folder id,
     *   or the special editor area id returned by getEditorArea
     */
    public void addView(String viewId, int relationship, float ratio,
            String refId);

在eclipse-RCP中许多系�l�内�|�菜单，可以直接拿过来��用，如ActionFactory.CLOSE�Q�ActionFactory.CLOSE_ALL�Q�ActionFactory.SAVE�Q�ActionFactory.SAVE_AS�Q�ActionFactory.DELETE�{��?br />可以通过saveAction = ActionFactory.SAVE.create(window);创徏Action
需要��?div style="display: inline-block; ">ActionFactory.SAVE,

ActionFactory.SAVE_ALL变�ؓ可用状态，只需要设�|�编辑器EditorPart的isDirty()�Ҏ��q�回为true卛_��?br /> ActionFactory.SAVE_AS讄��

�~�辑器EditorPart的iisSaveAsAllowed()为true卛_��?br /> 但是

ActionFactory.DELETE需要其他视图或�~�辑器中注册全局的句柄，可以通过如下�Ҏ��使用editorSite.getActionBars().setGlobalActionHandler(

ActionFactory.DELETE.getId(), new CustomAction(););

先定一个适配器类�Q��承XmlAdapter,可以��抽象类转换为可以识别的传输对象

public class UserTOAdapter extends XmlAdapter<TO, User> {

    @Override
    public User unmarshal(TO to) throws Exception {
        return (User)to;
    }

    @Override
    public TO marshal(User user) throws Exception {
        return (TO)user;
    }

}

在WebService接口中定义参数�{换的�Ҏ��Q�如�?br />

@WebService
public interface TypeConvert {
    @WebMethod
    @XmlJavaTypeAdapter(UserTOAdapter.class)
    User addUser(User user);
}
