Hi all,
This question may have been answered before. If so, I apologise.
When setting up a text widget using a ysize of 1, it appears to be
impossible to later extend the widget to a size > 1. The text appears on
one continuous line.
I've tried the folowing program under 5.0 - 5.3 on Alpha/VMS and NT and
the same effect is noticed on them all.
pro try_tab
base_1 = widget_base(column=1)
base_2 = widget_base(column=1)
text_1 = widget_text(base_1,value=['one'], ysize=1)
text_2 = widget_text(base_2,value=['one','two'], ysize=2)
widget_control,base_1,/realize
widget_control,base_2,/realize
wait,5.0 ; Just wait
for a while to enable change to be seen
widget_control,text_1,set_value=['eight','nine','ten'],ysize =3
widget_control,text_2,set_value=['eight','nine','ten'],ysize =3
end
If line 4 is replaced by
text_1 = widget_text(base_1,value=['one'], ysize=2)
the required result is obtained. However, additional blank lines don't
look too good.
Is there a better workaround?
Regards,
Ian
