Centering/Positioning a WebDialog at Load

Jim

This is a How-To demonstrating one way of positioning a WebDialog at the time it is first shown.

The ruby file:


w=UI;;WebDialog.new

f = File.dirname(__FILE__) + "/w.html" 
w.set_file( f )

w.add_action_callback("move") { |d, a|
  xy, wh = a.split(";")

  x, y = xy.split(",")
  x = x.to_i
  y = y.to_i

  w, h = wh.split(",")
  w = w.to_i
  h = h.to_i

  d.set_position((x - w)/2, (y - h)/2)
}
w.show

The html file:


<html>
  <head>
    <script>
      function move_to_center() {
	window.location = "skp;move@" + screen.width + "," + screen.height + ";" + document.body.offsetWidth + "," + document.body.offsetHeight;
      }
    </script>
  </head>
  <body onLoad="move_to_center()">
    Hi
  </body>
</html>

Another way is to execute a script in the dialog's show method:


w.show { w.execute_script("move_to_center()") }

You then eliminate the need for the "onLoad" in the html body tag.

Hey Jim. Is there a question here, or are you posting how to do it?

Heh, it's supposed to be a how-to in reponse to this question.
