title: Resize GtkMessageDialog in php
body: <p>I need to resize a GtkMessageDialog in php to have enough space for long string (dont want a new line)!</p>
  
  <p>Create it:</p>
  
  <pre><code>$dialog = new GtkMessageDialog($this-&gt;window, Gtk::DIALOG_MODAL, Gtk::MESSAGE_QUESTION, Gtk::BUTTONS_YES_NO, "");
  </code></pre>
  
  <p>Set the message output:</p>
  
  <pre><code>$message = "I NEED A LONG STRING TO DISPLAY IN THE DIALOG\n"
  $dialog-&gt;set_markup($message);
  </code></pre>
  
  <p>How its possible to adjust the dialog size? (the string should fit in one line)</p>
  
  <p>Thanks and greets</p>
