Question

I have a Nebula Grid (org.eclipse.nebula.widgets.grid.Grid) control in my view in Eclipse RCP. I would to make the row header of this grid visible so that, at runtime it displays row numbers like following photo:

Now, my requirement is that I want to display a text/char on the row header column, like other column headers (e.g. Full Name, Designation, etc). How can I achieve this on the Nebula Grid? Or, is it not possible by this Nebula Grid control? What could be my alternative?

Answer 1

I finally achieved the required functionality in nebulla Grid by implementing the method :
public void paint(GC paramGC, Object paramObject) {implementaion code }
inside interface :
setTopLeftRenderer(new IRenderer() { //interface methods}
as follows :

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;
    }
});

Where, grdTable is the Grid being used in the view.
