Hello LiveCoders

Just wondering how you would approach reading the INNER Content of a group to check if I should activate the scrollbar or not. Both vertical and horizontal I guess. I'm kinda scratching my head on this, so I thought I'd ask cuz I'm sure its been done.

Thanks,

Tom

Hi Tom,

you can compare
1. -> the width/height of grp XYZ = the actual "visible" size, not all content may be visible.
with
2. -> the formattedwidth/formattedheight of grp XYZ = the size necessary to display all its content.

if 2 > 1 then scrollbars neccessary

got it. didn't know about the formatted width function. Thank you Klaus.

Hi TOm,

check the dictionary for "formatted*******"!

There are a LOT of "formatted" things that you can query,
even the widht/height/top/left/right etc. of text chunks in fields!
Love it!

I see that ......very useful functions indeed. I've done the whole "looking through dictionary" thing before, and saw a lot of useful functions.... but its hard to remember them all until one uses them somewhere.

Thanks brother....
