我们可以在Eclipse RCP中的星云网格中的行标题列上设置文本吗?

我的问题:我在Eclipse RCP的视图中有一个nebulla Grid(org.eclipse.nebula.widgets.grid.Grid)控件。我可以通过以下代码使此网格的RowHeader可见: Grid grdTable = new Grid(compParent,SWT.BORDER | SWT.H_SCROLL);         grdTable.setRowHeaderVisible(真); 这样,在运行时它会显示如下图所示的rownumbers:

现在,我的要求是我想在RowHeader列上显示text / char,就像其他列标题一样。全名,指定等。如何在nebulla网格上实现这一目标?或者,这个nebulla Grid控件不可能吗?可能是我的另类选择?

我终于通过实现方法在nebulla Grid中实现了所需的功能: public void paint(GC paramGC,Object paramObject){implementaion code} 内部界面: setTopLeftRenderer(new IRenderer(){// interface methods} 如下:

grdTable.setTopLeftRenderer(new IRenderer() {
    @Override
    public void setSize(int paramInt1, int paramInt2) {
    // TODO Auto-generated method stub  
    }

    @Override
    public void setSize(Point paramPoint) {

    // TODO Auto-generated method stub

    }           
    @Override
    public void setSelected(boolean paramBoolean) {
    // TODO Auto-generated method stub
    }

    @Override
    public void setMouseDown(boolean paramBoolean) {
    // TODO Auto-generated method stub      
    }

    @Override
    public void setLocation(int paramInt1, int paramInt2) {
    // TODO Auto-generated method stub              
    }

    @Override
    public void setLocation(Point paramPoint) {
    // TODO Auto-generated method stub                  
    }

    @Override
    public void setHover(boolean paramBoolean) {
    // TODO Auto-generated method stub              
    }

    @Override
    public void setFocus(boolean paramBoolean) {
    // TODO Auto-generated method stub              
    }

    @Override
    public void setExpanded(boolean paramBoolean) {
    // TODO Auto-generated method stub              
    }

    @Override
    public void setDisplay(Display paramDisplay) {
    // TODO Auto-generated method stub              
    }

    @Override
    public void setBounds(int paramInt1, int paramInt2, int paramInt3,
                    int paramInt4) {
    // TODO Auto-generated method stub                  
    }

    @Override
    public void setBounds(Rectangle paramRectangle) {
    // TODO Auto-generated method stub          
    }

    @Override
    public void paint(GC paramGC, Object paramObject) {
    // TODO Auto-generated method stub
    //paramGC.setAntialias(1);
    paramGC.setBackground(SWTResourceManager.getColor(240, 240, 240));
    Rectangle rect=new Rectangle(0, 0, 20, 2*(grdTable.getGroupHeaderHeight()));
        paramGC.fillRectangle(rect);
        //making foreground color of the Rectangle to be of text in ColumnHeaders   
    paramGC.setForeground(SWTResourceManager.getColor(0, 0, 0));
        //drawing appropriate text on the topLeftCorner of Grid
    paramGC.drawText("#",5,10,false);               
    }

    @Override
    public Point computeSize(GC paramGC, int paramInt1, int paramInt2,
                    Object paramObject) {
    // TODO Auto-generated method stub

    return null;
    }
});

其中,grdTable是视图中使用的网格。

更方便的方法是使用GridTableViewer:

        GridTableViewer grid = new GridTableViewer(parent, SWT.BORDER
            | SWT.V_SCROLL | SWT.H_SCROLL);
    grid.getGrid().setRowHeaderVisible(true);
    grid.setContentProvider(new ArrayContentProvider());
    grid.setRowHeaderLabelProvider(new CellLabelProvider() {

        @Override
        public void update(ViewerCell cell) {
            cell.setText(cell.getElement().toString());
        }
    });
