What is the width of a scroll bar?

[TimSNL]

Hello

I need to find (at runtime) the width of the vertical scroll bar up the side of my TDBEdit. I need this to dynamically resize the columns to avoid the infamous horizontal scrool bar popping up down the bottom of the grid when I don't want him .

Thanks for your help

Each object that has a canvas has a width property and a clientwidth property. the scrollbar is not parth of the client canvas , therefore the objects width minus the clientwidth is the size of the scroll bar. Normally the is about 20 pixels but the code below will tell you exactly.

Label1.Caption:=IntToStr(MyObject.Width-MyObject.ClientWidth);

Substitute MyObject with the name of the control you are testing.

hope this helps
