I am looking for a scriptlet example to know overflow of a text field. I'd like to pass a font, font size and a string from a text field and find out if the string does not fit to the length of the textfield. If yes, I am going to show a box with a smaller font size, if no, a box with a default font size. Ideally, it should be something like 'fit to the box', providing a size of the box and textfield. In this solution, the font size is not changing, just horizontal character spacing is changing
