What function do I use to measure the length in pixels of a string in a
particular font and fontsize? I have looked "everywhere" in different help
files, but can't find it.
Thanks,
Paal

Typically, 2 minutes after posting the question I found at least on solution
in TFont:GetTextSize. But are there any *function* to call also (something
like GetTextSizeFromFont( cFontName, cTextToMeasure )?

Paal,
Is the correct function. Your function prototype is not valid since it does
not take care of font size or bold state.
BTW, you can also use TCanvas:TextExtent()

Yes I forgot this wasn't Xbase++, there it would be: cFontName := "10.Arial
Bold"

Ok.
I have experimented and it's not enough to know the text width with a
certain font. I also need to know the system font DPI size set in the
Display properties -> Settings -> the General tab -> Display DPI Setting.
Please se the attached picture.
From Xbase++ I know that there is a function in USER32.DLL,
"GetSystemMetrics", parameter no. 30, which returns a value indicating the
DPI size. But I'm in the beginning of a learning process and for now I
would be very happy to avoid learning using DLL's and that kind of stuff.
Are there any ready made function available in (ok, or through) Xailer?

Paal

Thank you very much, that was it! I tried it earlier today and don't
