Thank you to the both of you!
I got it working great now.
I know my code there has some problems, that was just a small part of
a bigger program
I used to make showing you guys easier.
Thanks again!

Sent the id of widget_text to the handler in the info structure and
then update it from within the event handler:
1. Add wt0 to the info structure:
info = { $
id:wt0 $
}
....
2. use wt0 in the event handler:
filepicked = DIALOG_PICKFILE (/READ)
widget_control, info.id, set_value=filepicked

You have several problems, but here is a quick and dirty job
that at least solves this one:
PRO test_event, ev
widget_control, ev.id, get_value=value
widget_control, ev.top, get_uvalue=info
if value eq '...' then begin
filepicked = DIALOG_PICKFILE (/READ)
if filepicked eq "" then return
print, "File picked"
print, filepicked
filename = file_basename(filepicked)
widget_control, info.wt0, set_value=filename
fp = ptr_new(filepicked)
END
END
PRO test, value
main = widget_base (title='PRO', MBAR=bar, /row)
wt0 = WIDGET_TEXT(main, XSIZE=15, /EDITABLE)
findfiles = widget_button (main, value='...')
widget_control, main, /realize
info = {wt0:wt0}
widget_control, main, set_uvalue=info
xmanager, 'test', main
END
Cheers,
David

Dialog_pickfile has the GET_PATH keyword which would seem to be what
you want.
