OK,
More playing around reveals that putting sliders in different bases
prevents unwanted interaction.
Andrew C.
e.g. :-
PRO slider_Demo_event, ev
widget_control,ev.id,get_Uvalue= uv
Case uv OF
'CT SLICE' : Begin
CT_slice = ev.value
print,'CT_slice = ',CT_slice
End
'CT CONTRAST' : Begin
CT_contrast = ev.value
print,'CT_Contrast = ',CT_Contrast
End
'DRAW' :
'JUNK' :
'EXIT' : Widget_Control,ev.top,/Destroy
Else : Message,'Dodgy Uvalue = ' + STRING(uv)
End
End
;........................................................... .......
PRO Slider_Demo
base = Widget_base(/row,Xsize=600)
basea = Widget_base(base,/Col,/Frame)
basec = Widget_base(base,/Col,/Frame)
baseb = Widget_base(base)
based = widget_base(base)
slice_slider_id = Widget_slider(basea,Min=0,max=128,Title='CT slice',$
Value=64,Uvalue='CT SLICE',/Frame)
contrast_slider_id = Widget_slider(basec,Min=0,Max=255,Title='CT
Contrast',$
Value=40,Uvalue='CT
CONTRAST',/Frame,/Vert)
exit_id = Widget_button(basea,Value='EXIT',Uvalue='EXIT')
draw_id = Widget_draw(baseb,xsize=300,ysize=300,/motion,Uvalue='DRAW')
junk_id = Widget_button(based,value='JUNK',Uvalue='JUNK')
Widget_control,base,/Real
Xmanager,'Slider_Demo',base
End

Hi Josh,
After playing around with Tracking Events and
Sensitising/De-sensitising
slider widgets, I don't think that's the way to go.
However, I altered the properties of my Logitech wheelmouse's scroll
wheel from "click/select" to "horizontal scroll", and Voila!, on a test
GUI with a vertical and horizontal slider, only one slider would
respond
to the wheel button, whilst the other had to be clicked on as per
normal.
Setting the whell button property to "vertical scroll" had the expected
opposite effect, in that the other slider responded to the wheel, etc.
Not exactly platform or user independent though.
I seem to recall a recent post from one of the IDL Guri saying that he
was in the process of creating a DLM for mouse control. A search on
that
might prove fruitful.
HTH,
Andrew
