Support for CellEditors as viewers

[ere]

Within the "what's new section" I found a statement "Support for CellEditors as viewers"

I guess/hope that with this feature I can bind the input and selection to a ComboBoxCell Editor within a table viewer. If this is the case, could you pls instruct me how to do this.

thanks

That just means that you can use a CellEditor just like any other widget/viewer. For example...

Code: Select all

package test;

import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.layout.RowLayout;
import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.Control;
import org.eclipse.jface.viewers.TextCellEditor;
import com.swtdesigner.SWTResourceManager;

public class Application_1 {
   protected Shell m_shell;
   /**
    * Launch the application.
    * @param args
    */
   public static void main(String[] args) {
      try {
         Application_1 window = new Application_1();
         window.open();
      } catch (Exception e) {
         e.printStackTrace();
      }
   }
   /**
    * Open the window.
    */
   public void open() {
      Display display = Display.getDefault();
      createContents();
      m_shell.open();
      m_shell.layout();
      while (!m_shell.isDisposed()) {
         if (!display.readAndDispatch()) {
            display.sleep();
         }
      }
   }
   /**
    * Create contents of the window.
    */
   protected void createContents() {
      m_shell = new Shell();
      m_shell.setSize(450, 300);
      m_shell.setText("SWT Application");
      m_shell.setLayout(new RowLayout(SWT.HORIZONTAL));
      {
         TextCellEditor textCellEditor = new TextCellEditor(m_shell, SWT.BORDER);
         Control control = textCellEditor.getControl();
         control.setBackground(SWTResourceManager.getColor(SWT.COLOR_LIST_BACKGROUND));
         control.setVisible(true);
      }
   }
}

Eric, is there any change for an WindowBuilder enhancement to support ComboBoxViewerCellEditor with the repsective dialogs to bind input, selection etc. as for ComboViewers ?

I've added now manually some code similar to this blog-entry:
http://splitshade.wordpress.com/2009/02 ... le-viewer/

Now, my screen works except that WindowBuilder generates parser exceptions.

We don't have any enhancements like that currently planned.

What exceptions? In general, you should not modify the initDataBindings() method in any way as it is parsed and regenerated as a unit. If you need to add addditional DB code that is not supported by SWT Designer, do it outside of that method
