OK, I'm trying to hijack the new Properties capabilities of iTools for
my own devious purposes, and I've managed whip up this test:
pro TestProps::Config
b=widget_base(/COLUMN)
; Create and initialize the component.
p=widget_propertysheet(b,VALUE=self)
widget_control,b,SET_UVALUE=self,/REALIZE
XManager,'TestPropsPropertySheet',b,/NO_BLOCK
end
function TestProps::Init
if self->IDLitComponent::Init(NAME='TestProps') eq 0 then return,0
self->RegisterProperty,'MY_FIRST_PROPERTY',/BOOLEAN, $
NAME='Propertus Incipiens'
return,1
end
pro TestProps__define
st={TestProps, $
INHERITS IDLitComponent, $
data:0}
end
Sadly enough, here's what happens:
IDL> a=obj_new('testprops')
IDL> a->Config
% Keyword MY_FIRST_PROPERTY not allowed in call to: WIDGET_PROPERTYSHEET
% Execution halted at: TESTPROPS::CONFIG 5
/home/jdsmith/idl/irs_cubism/cubism/cube/testprops__define.p ro
% $MAIN$
I'm really not sure how a property ID is getting transformed into a
keyword in this call... sounds like some internal _EXTRA hi-jinx to
me. What ingredient am I missing?
Thanks,
JD
