One question for those of you who have been using widget_tables,
The table that I'm creating needs to have a fixed (screen) size.
Initially, there is nothing to show on the widget_table, but later on,
I will need to show array[100] in the table.
When creating the table, I have added Y_SCROLL_SIZE=3, /SCROLL to fix
the size and enable the scroll. "During" the program, I have used the
"Set_Value" and "Get_value" to confirm that the data is correctly
passed into the table, however, I cannot scroll down to view the rest
of the data.
What is missing here?
ANY comments is welcomed!
Below is a sample code to illustrate my problem.
;====================================================
; Event-handler routine for 'Quit' button
PRO table_widget_example22_quit_event, ev
WIDGET_CONTROL, ev.TOP, /DESTROY
END
; Widget creation routine.
PRO table_widget_example22
;;code was originally one of IDL's examples:
table_widget_example2.pro ;;
; Create some structure data.

ROW_LABELS='', COLUMN_LABELS='', $
/RESIZEABLE_COLUMNS, /SCROLL, Y_SCROLL_SIZE=3)
b_quit = WIDGET_BUTTON(base, VALUE='Quit', $
EVENT_PRO='table_widget_example22_quit_event')
