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
