Dynamic Text Box / Object resizing

I use a lot of xml translation in my projects, where text variables are updated based on the choice of language. I would like to see the text boxes or objects containing the text variable (e.g. Text_1) change size dynamically to fit the length of the new text. 

E.g. butterfly is 'motyl' is Polish (PL_Text_1) , but 'schmetterling' in German (DE_Text_1). Both of these texts need to fit in a single button nice and snug, whenever the language variable changes. 

Currently, the textbox / object will only resize according to the length of Text_1, not the updated variables DE_Text_1 or PL_Text_1.
