[news.eclipse.platform.swt] Re: Adding element in TableViewer and edit i

[oliver.pfau@xxxxxxxxxxxxxxxxxxx (Oliver)]

The table is configured by this (3 columns the RGB values and 4th column a 
color chooser):

final CellEditor compEditor = new TextCellEditor(table);
final CellEditor colorCellEditor = new ColorCellEditor(table);

colorTable.setCellEditors(new CellEditor[] {
	                              compEditor, compEditor,
	                              compEditor, colorCellEditor
		                          });



Here the implementation of ICellModifier:

colorTable.setCellModifier(new ICellModifier() {
				
 @Override
 public boolean canModify(final Object element, final String property)
 {
   return true;
 }
 
 @Override
 public Object getValue(final Object element, final String property)
 {
   final RGB rgb = (RGB) element;
   if (COLUMN_RED.equals(property)) {
     return Integer.toString(rgb.red);
   }

   if (COLUMN_GREEN.equals(property)) {
     return Integer.toString(rgb.green);
   }

   if (COLUMN_BLUE.equals(property)) {
     return Integer.toString(rgb.blue);
   }

   if (COLUMN_RGB.equals(property)) {
     return rgb;
   }

			 
 @Override
 public void modify(final Object element, final String property, final 
Object value)
 {
   isDirty = true;

   final RGB rgb = (RGB) ((TableItem) element).getData();

   if (COLUMN_RED.equals(property)) {
     try {
       rgb.red = limitRGB(Integer.parseInt((String) value));
     } catch (final NumberFormatException nfe) {
     }

     colorTable.update(rgb, null);
   } else if (COLUMN_GREEN.equals(property)) {
     try {
       rgb.green = limitRGB(Integer.parseInt((String) value));
     } catch (final NumberFormatException nfe) {
     }

     colorTable.update(rgb, null);
   } else if (COLUMN_BLUE.equals(property)) {
     try {
       rgb.blue = limitRGB(Integer.parseInt((String) value));
     } catch (final NumberFormatException nfe) {
     }

     colorTable.update(rgb, null);
   } else if (COLUMN_RGB.equals(property)) {
     final RGB col = (RGB) value;
     rgb.red = col.red;
     rgb.green = col.green;
     rgb.blue = col.blue;

     colorTable.update(rgb, null);
   } 
   else {
     throw new IllegalArgumentException("Unsupported property for 
editing: " + property);
   }
 }
});
