Question:
I want to display a text string in a limited space on screen and need to know if it's too long so I can, say, split it into two lines or reduce the font size. How can I get this information?

Answer:
CFont has a function TextWidthInPixels(TDesC&) which does just this for the text displayed in the chosen font.

CFont* font;
...
TPtrC myLongString = ...;
TInt width = font->TextWidthInPixels(myLongString);
