Hello all,
I've been experimenting with WIDGET_TEXT hoping to make a text box
which will show the user messages from anywhere in my application.
The goal is to have the messages appended to the text box on a new
line. Then when there are more messages than lines, the new message
will be placed on the bottom line and the oldest message will be
knocked off the top. As it stands,
widget_control, (*state_ptr).text_box, set_value = 'my text', /append
seems to add the new text message to the list, but I need to scroll
down (if /scroll is set), or down arrow to see the added text. Adding
the lines
(*state_ptr).top_line = (*state_ptr).top_line +1
widget_control, (*state_ptr).text_box, set_text_top_line = $
(*state_ptr).top_line
seems to work ((*state_ptr) is the uvalue of my top level base), but
adding these lines of codes at every message and adding a new variable
to my state_ptr seems a very inelegant solution. Is there a better
way to avoid this work around?
I'm running 5.1 beta3 on Win NT.

P.S. Is there really no way I can get rid of the frame around a text
box under Windows!?!
