JFace TableViewer - Setting font color for all Cells in table

Question

I have asked a very similar question, but I ended up using images instead of changing the color.

I want all the text in the cells to be dark grey. I understand that you have to assign each column. But I do not how to do it.

This is one of my columns in my TableViewer.

col = new TableViewerColumn(this , SWT.NONE);
col.getColumn().setWidth(200);
col.getColumn().setText("Printer/Profile");
col.setLabelProvider(new ColumnLabelProvider() {
    @Override
    public String getText(Object element) {
        AplotResultsDataModel.ResultsData p = (AplotResultsDataModel.ResultsData) element;
        return p.getPrinterProfile();
    }
}); 

How would I change the above code to incorporate setting the font color to dark gray?

EDIT

If I am using the switch, how does it know how many columns I have? also how do I set the column names? Here is how I have it set up right now

TableViewerColumn col = new TableViewerColumn(this , SWT.NONE);
  col.getColumn().setWidth(150);
  col.getColumn().setText("ItemId");
  col.setLabelProvider(new ColumnLabelProvider() {
     @Override
     public void update(ViewerCell cell)
     {
         Object element = cell.getElement();
         if(element instanceof AplotPDFDataModel.FileNameData)
         {
            AplotPDFDataModel.FileNameData p = (AplotPDFDataModel.FileNameData) element;
            cell.setForeground(ColorConstants.darkGray);
            switch(cell.getColumnIndex())
            {
               case 0:
                  try {
                     cell.setText(p.getRev().getStringProperty("item_id"));
                  }
                  catch (TCException e) {
                     e.printStackTrace();
                  }
                  break;
               case 1:
                  try {
                     cell.setText(p.getRev().getStringProperty("item_revision_id"));
                  }
                  catch (TCException e) {
                     e.printStackTrace();
                  }
                  break;
               case 2:
                  cell.setText(p.getPRLValue().toString());
                  break;
               case 3:
                  cell.setText(p.getMarkupValue());
                  break;
               case 4:
                  cell.setText(p.getFileName());
                  break;
             }
         }
     }
 });

I would use the method update(ViewerCell cell) of the ColumnLabelProvider instead of getText() . Then you can call ViewerCell#setForeground(Color color) :

public class ColorColumnLabelProvider extends ColumnLabelProvider {
    @Override
    public void update(ViewerCell cell)
    {
        Object element = cell.getElement();
        if(element instanceof AplotResultsDataModel.ResultsData)
        {
            AplotResultsDataModel.ResultsData p = (AplotResultsDataModel.ResultsData) element;

            cell.setForeground(YOUR_COLOR);
            switch(cell.getColumnIndex())
            {
                case 0:
                    cell.setText(p.YOUR_FIRST_TEXT);
                    break;
                case 1:
                    cell.setText(p.YOUR_SECOND_TEXT);
                    break;
                case ...
            }
        }
    }
}

Then use:

col.getColumn().setWidth(150);
col.getColumn().setText("ItemId");
col.setLabelProvider(new ColorColumnLabelProvider());

Since I switch the column index, you can use this ColorColumnLabelProvider for all your columns.

Don't forget to dispose the color somewhere.

If you use ColorConstants of Draw2d , you don't need to dispose them.

In your case ColorConstants.darkGray would do the job.

ALTERNATIVE :

You can also define a ColumnLabelProvider that implements IColorProvider :

public class ColorColumnLabelProvider extends ColumnLabelProvider implements IColorProvider {

    @Override
    public Color getBackground(Object element) {
        return null;
    }

    @Override
    public Color getForeground(Object element) {
        return YOUR_COLOR;
    }

    @Override
    public String getText(Object element) {
        AplotResultsDataModel.ResultsData p = (AplotResultsDataModel.ResultsData) element;
        return p.getPrinterProfile();
    }

}
