1. 实现视图

1. 定义扩展

 

      <view
            allowMultiple="false"
            category="com.sg.intellifmea.views"
            class="com.sg.intellifmea.view.DocumentView"
            icon="icons/fldr_unrec.gif"
            id="com.sg.intellifmea.view.DocumentView"
            name="文档"
            restorable="true">
      </view>

2. 创建TableViewer

文档视图上是以列表的形式显示文档的，因此，我们不需要定义column

    @Override
    public void createPartControl(Composite parent) {
        viewer = new TableViewer(parent,SWT.BORDER);
        viewer.setLabelProvider(new LazyDTOStyledCellLabelProvider());
        viewer.setContentProvider(ArrayContentProvider.getInstance());
    }

3. LabelProvider

package com.sg.hyperobject.ui.viewers;

import java.text.ParseException;
import java.text.SimpleDateFormat;

import org.eclipse.jface.viewers.StyledCellLabelProvider;
import org.eclipse.jface.viewers.StyledString;
import org.eclipse.jface.viewers.ViewerCell;
import org.eclipse.swt.graphics.Image;

import com.sg.hyperobject.datamanager.dt.LazyDTO;

public class LazyDTOStyledCellLabelProvider extends StyledCellLabelProvider{

    private SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    private SimpleDateFormat sdf1 = new SimpleDateFormat("MM/dd");

    @Override
    public void update(ViewerCell cell) {
        LazyDTO ldto = (LazyDTO)cell.getElement();
        StyledString styledString= getStyleString(ldto);
        
        cell.setText(styledString.toString());
        cell.setStyleRanges(styledString.getStyleRanges());

        cell.setImage(getImage(ldto));
        
        super.update(cell);
    }

    protected StyledString getStyleString(LazyDTO ldto){
        StyledString sString = ldto.getStyleString();
        String user = ldto.getText("md$user");
        sString.append(user, StyledString.COUNTER_STYLER);
        String cdate = ldto.getText("md$cdate");
        if(!"".equals(cdate)){
            try {
                cdate = sdf1.format(sdf.parse(cdate));
                sString.append(" "+cdate,StyledString.COUNTER_STYLER);
            } catch (ParseException e) {
            }
        }
        return sString;
    }

    protected Image getImage(LazyDTO ldto){
        return ldto.getIcon();
    }

}

注意，这里我们不为这个viewer setInput()

我们需要监听当前选择的项目来设置为viewer的input

所以接下来设置view侦听Page的Selection

4. 侦听Page Selection

    @Override
    public void createPartControl(Composite parent) {
        viewer = new TableViewer(parent, SWT.BORDER);
        viewer.setLabelProvider(new LazyDTOStyledCellLabelProvider());
        viewer.setContentProvider(ArrayContentProvider.getInstance());
        viewer.setInput(new ArrayList<LazyDTO>());
        getSite().getPage().addPostSelectionListener(
                IntelliFmeaViews.PROJECT_NAVIGATOR, this);
    }

当然，前提是你所侦听的部件已经把Selection注册到了Page

5. 实现selectionChanged

    @Override
    public void selectionChanged(IWorkbenchPart part, ISelection selection) {
        if (selection.isEmpty())
            return;
        LazyDTO element = (LazyDTO) ((StructuredSelection) selection).getFirstElement();
        String ouid = element.getOuid();
        Assert.isNotNull(ouid);
        if(ouid.equals(master)){
            return;//没有改变
        }
        setPartName("文档 -"+element);
        HashMap<String, String> condition = new HashMap<String,String>();
        condition.put("project", ouid);
        ArrayList<LazyDTO> input = new ArrayList<LazyDTO>();
        try {
            ArrayList<ArrayList<String>> result = DMModel.getDMCbyName("Document").listData(condition);
            if(result!=null){
                for(ArrayList<String> row:result){
                    LazyDTO ldto = new LazyDTO(row.get(0));
                    input.add(ldto);
                }
            }
        } catch (Exception e) {
        }
        viewer.setInput(input);
    }

现在看不到效果。等我做完了注册文档后，自然就可以看到了。
