The event on.resize is fired when the user resizes the window where the lua script is.
It has no argument.
It's a good place to put your global window-size-related variable since this event only fires when the script's frame's size changes (see Example).
Example
Below is an example of a program that creates/updates the "theHeight" ad "theWidth" global variables whenever the user resizes the widget's frame:
function on.resize() --Define a function for the event
theWidth = platform.window:width()
theHeight = platform.window:height()
end
You can then refer to the height and the width of the widget by calling the global variables instead of the methods.
