Auto-height overflow
Here’s a handy little function which I have found useful when localising my HUDs; it can be painful when the text doesn’t quite fit and some of it disappears, so this function automatically tweaks the height of the text until it does fit. (Currently only for buttons, check boxes and labels, but easy to extend for other component types) – by psychicsoftware

if ( kType==hud.kComponentTypeButton ) then
nLines = hud.getButtonTextTotalLineCount ( hComp )
nHgt = hud.getButtonTextHeight ( hComp )

nLines = hud.getLabelTextTotalLineCount ( hComp )
nHgt = hud.getLabelTextHeight ( hComp )
