title: adding string object to gArray
body: <p>I want to add some string objects in GArray. But when i read the API manual of </p>
  
  <p>g_array_new(), it seeks the size of the element to be added while creating the array, but </p>
  
  <p>different string objects have different length, so how can i cope with this issue.</p>
  
  <p>Regards,
  iSight</p>
