Hi there,
i like to have a widget doing the following:
PROBLEM1:
if the button 'range1' has been pushed, then change the UVALUE from
'range' to 'range1'
if the button 'range2' has been pushed, then change the UVALUE from
'range' to 'range2'
...
depending on the new uservalues in another program the rangings of the
plots are been set...
but for some reason it won't work, and actually i think to do it with
the UVALUE's isn't a bad idea, is it?
PROBLEM2:
when the USERVALUE's have been set,
i'd like to have a message like:"uservalue is now range1"
see the source below how i tried to do that
any suggestions? :-/
Ralf
some snipsnaps of the source:
--------------------------------------------------
PRO clus
...
desc1=REPLICATE({flags:0,name:' '},4)
desc1.flags=[1,0,0,2]
desc1.name=['Range','range1','range2','userrange']
...
but(8) =
CW_PDMENU(pan1,desc1,UVALUE='range',/RETURN_INDEX,FONT=butfo nt)
...
--------------------------------------------------
PRO clus_event
...
WIDGET_CONTROL,eve.id,GET_UVALUE=uval
;
CASE uval OF
"range" : BEGIN
CASE eve.value OF
1 : SET_UVALUE='range1' , PRINT, 'uservalue is now range1'
2 : SET_UVALUE='range2'
3 : SET_UVALUE='userrange'
ENDCASE
...
-------------------------------------------------
PRO plot
...
IF (UVALUE EQ 'range1') THEN BEGIN
;B_x
index=0
yranmax=[1024.,512.,256.,128.,64.,32.,16.,8.,4.,2.,1.]
IF maxmag0 GT 2048. THEN yrange = [0.,2048.] ELSE BEGIN
WHILE (yranmax(index) GE maxmag0) AND (index LT 10) DO BEGIN
print,'yranmax',yranmax(index),maxmag0
yrange0=[0.,yranmax(index)]
index=index+1
ENDWHILE
ENDELSE
...
ENDIF
