This seems to be weirdly problematic.
What I want to do is to load a string from somewhere else (uknown during edit time), display it in a Text object, and then scale a background sprite (or better a 9-patch but it's not important) so that I have a nice box filled with text.
Think speech bubbles in any messaging application.
Reading the forum I came up with this:
But it results in werid behaviour in which the sprite scales on a second button click instead of immediately. Larger delay than "wait 0" is undesirable because it doesn't look neat.
So any better ways to do this? Perhaps C3 has some new features that would facilitate measuring text?
