In addition to what Michael said above, look into the GetEnvironment function.  It returns an environment object.  You can then check environment.screenheight and environment.screenwidth (in pixels), then call PixelsToUnits on each for the maximum screen height and width.  This should work in any resolution.  Caveat: I had to add an offset to both to make it fit the screen perfectly.  You can experiment to get the right numbers, but I ended up with (-)800 for height and (-)100 for width.  Code would look something like this:



 



Long   ll_height, ll_width



Environment   le_env



CONSTANT   Integer   HEIGHT_OFFSET = 800



CONSTANT   Integer   WIDTH_OFFSET = 100



 



GetEnvironment(le_env)



ll_height = le_env.screenheight



ll_width = le_env.screenwidth



ll_width = PixelstoUnits(ll_width, XPixelsToUnits!)

ll_height = PixelstoUnits(ll_height, XPixelsToUnits!)



this.height = ll_height - HEIGHT_OFFSET  //from open or some window event - offset is optional

this.width = ll_width - WIDTH_OFFSET  //from open or some window event - offset is optional
