[pde-dev] RE: Getting the Value from a org.eclipse.swt.widgets.Combo

["Mike Evans, Incremental Ltd." <mike.evans@xxxxxxxxxxxxxxxxxx>]

Try something on the lines of:

final CCombo combo = new CCombo( parent, SWT.FLAT );
combo.setLayoutData( new GridData() );
combo.setText( initialValue );
combo.setItems( array );
combo.addModifyListener( new ModifyListener() {
	public void modifyText(ModifyEvent e) {
      	String text = combo.getText().trim();
		System.out.println("your selection is "  + text );
      }
}

Have fun with SWT...

Hi there
first post from a newby

I am (trying) to develop a ComboBox drop down widnow that popsup and creates
a Combo. All is working, and I am populating the drop down with

combo.add(items[i]); 

I have also added a method
protected void buttonPressed(int buttonId) {
       if (buttonId == IDialogConstants.OK_ID) {
           
           System.out.println("your selection is "  +
combo.getSelectionIndex()+  "somthing");
        }
       super.buttonPressed(buttonId);
       
   }
        }
       super.buttonPressed(buttonId);
       
   }

But when I run this, I get an error in the System.out.println that:
Unhandled event loop exception
Reason:
java.lang.NullPointerException


What is the correct way to get data from a dropdown in a combo?

Any help greatly apreciated
