Hi folks,

I write a procedure which reads an image when a button pressed.

pro BTLoad_Event, event
WIDGET_CONTROL, event.id, GET_UVALUE = info
fname = DIALOG_PICKFILE(FILE = info.filename, /READ, FILTER = '*.hdr',
$
/MUST_EXIST, /FIX_FILTER, PATH = path, /NOCONFIRM)
IF fname NE "" THEN BEGIN
Read_Analyze, fname, info.image
;^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ENDIF
end

pro Read_Analyze, File, Image
;it reads some data from the file and modifies some fields in Image
end;

I see that in the Read_Analyze, data is read correctly, but in
BTLoad_Event, info.image is not modified. Anyone can tell me why ?

Best regards,
Tri.
