// TODO Auto-generated constructor stub
}

private Text text=null;
private String mess=null;

public static String show(Shell parent, String title,String message){
Question q=new Question(parent, title, null,message, QUESTION, new
String[]{IDialogConstants.YES_LABEL,IDialogConstants.NO_LABE L}, 0,"");
if(q.open()==0)
return q.text.getText();
return "";
}

protected Control createMessageArea(Composite composite) {

text = new Text(composite, SWT.SINGLE);
text.setText(mess);
GridData data=new GridData(
GridData.HORIZONTAL_ALIGN_CENTER
| GridData.VERTICAL_ALIGN_BEGINNING);
data.widthHint =
convertHorizontalDLUsToPixels(IDialogConstants.MINIMUM_MESSA GE_AREA_WIDTH);
