Hi all,
Now the problem is clear and the solution found. Thanks to all .
According Fred's advice onPaint is avoided.
I tried baseform.onfocusedwidgetchanged( newwidget .......)
It works only when newwidget object is a Mse*Object ?
I mean
If (newwidget is myownobject ) return false then
I can not adjust the caption
see :
https://www.mail-archive.com/[email protected]/msg12722.html
so the only solution is oncreate form which is not so smart.
Regards
Med.

Hello mohamed,

That's because you probabely use a proportional font, where all the
characters have their individual width and font.width returns that of a
"representative" character, often an "m". If you used a monospaced font,
the font.width would be the same for all characters, although, of course,
it looks different.
But maybe you can make use of one of the "textrect" functions of the
"msedrawtext" unit, which generally take a canvas object as their first
parameter (implicitely specifying the font to check) and several other
parameters, often a string to be evaluated. They return a "rectty" record,
where the "cx" field contains the width value you are looking for.
You probabely will have to select the appropriate version of the function
according to your needs; the unit is located in the "mse.common/graphics"
directory, the file name is "msedrawtext.pas".
