Dear M. (what does M. stand for)
I have tried it but it works.
Here is my example. where is it different to yours.
PRO test_event,ev
cmd=WIDGET_INFO(ev.id,/uname)
CASE cmd[0] OF
'SWITCH': $
WIDGET_CONTROL,WIDGET_INFO(ev.top,find_by_uname='ROW1'),/sen sitive
'QUIT':WIDGET_CONTROL,ev.top,/destroy
ELSE:
ENDCASE
END
PRO test
tlb=WIDGET_BASE(col=3)
row1=WIDGET_BASE(tlb,sensitive=0,uname='ROW1')
st = ['A','B','C','D']
filterID = WIDGET_DROPLIST(row1, VALUE=st, UVALUE='dont_bug_me')
button=WIDGET_BUTTON(tlb,value='SWITCH',uname='SWITCH')
quit=WIDGET_BUTTON(tlb,value='QUIT',uname='QUIT')
WIDGET_CONTROL,/realize,tlb
XMANAGER,'test',tlb
END
I have tested on suSE 8.2 (KDE3.1 and the newest X-Server)
help,!version,/str
** Structure !VERSION, 8 tags, length=76, data length=76:
ARCH STRING 'x86'
OS STRING 'linux'
OS_FAMILY STRING 'unix'
OS_NAME STRING 'linux'
RELEASE STRING '5.6'
BUILD_DATE STRING 'Oct 26 2002'
MEMORY_BITS INT 32
FILE_OFFSET_BITS
INT 64
