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.
