Windows focus on center of Layout

Hi guys..

I have build a HTML 5 game which the layout size setup to 2560 x 1440.

But I have setting window size 1680 x 1050

the focus of windows view in design layout in top left

how to change the focus on top center or bottom center?

I set that size of layout smaller than window size because the user screen is usually use in 1680x1050 until 1024x768

and then for supporting high screen resolution I would like to change window size to 2560x1440.

I don't want to scale to be small size or big size.

please help... I do need it.

YOu can't change it in design view, just add a sprite with scroll to and put it where you want the screen to center. The design view and the run time view don't have to have the same start points.

Before you play with "Scroll To" try switching on "Unbounded Scrolling" in the layout properties.

It releases that top left corner, so it can center on the screen size selected.

Thank you Every One..!!
