One Rect For All specificaiton

In showAll to position controls in the corners you need to know the ratio of the device screen. You then multiply that by the width or height, to work out the position.

OK I tried this and failed.   FYI you need all splash screens installed in standAlone config to get iOS screen rects properly registered by LC… but this did not help.

Suffice to say that my implementation of the “use the ratio) idea fails when driving a 16 X 9 stack out to iPad in the simulator

function  getAltCardHeight tScreenRect

# e.g. 0,0,736,414 OR 0,0,1024,768 etc.


   # get ratio for landscape height
   # attempt to determine height of card on any device:


   put ( item 4 of tScreenRect/item 3 of tScreenRect) into tRatioForVertical
   put ( (the width of this card) * tRatioForVertical) into tNewCardHeight
   return tNewCardheight

# use the above to set the bottom of a control

# to the bottom of the screen on any device

end getAltCardHeight

If anyone has a “real” algorithm (used and tested on multiple devices with different ratios, screen densities and pixel dimensions) that allows us to dynamically set a control to the bottom or right edge of the screen using showAll, please share. Either I am incredibly dense and missing something simple or we really have no method/algorithm to accomplish this...

Demo with new methods here:

 at least the “safe zone” for elements is clarified…
