Since we need to create a generic set of functions to accommodate several frameworks, we
have a couple of new functions like
setVisible
and
bringToFront
, which allows us to show or
hide the objects or re-order the display of the objects.
Here's the code for Corona SDK:
function setVisible(theObject, setHow)
if theObject == nil then return end
theObject.isVisible = setHow or false
end
And here's the code for Gideros Studio:
function setVisible(theObject, setHow)
if theObject == nil then return end
local setHow = setHow or false
theObject:setVisible(setHow)
end
The
bringToFront
function is defined as follows in Corona SDK:
function bringToFront(theObject)
if theObject == nil then return end
theObject:toFront()
end
