strange value of (ItemEvent).Selected

Hi,

Using an ItemListener, I wanted to know if the action that
triggered the
listener was a selection or anything else. I don't find
another way that
to find the value of oEvt.Selected returned when it's not a
selection
and to verify that value.

The value returned is 65535. All is working fine now, but I
wonder why
THAT value ?

Does someone know something about that ?

Here's the code of the CspListBoxListener::itemStateChanged
method :

------------------------------------------------------------
-----------
void CspListBoxListener::itemStateChanged( const
awt::ItemEvent& oEvt )
    throw ( RuntimeException )
{
//For an unknown reason, 65535 seems to be the value for a
deselection
    if(oEvt.Selected != 65535){
       
getDialog()->getAddonImpl()->setSelectedCsp(oEvt.Selec
ted);
       
((SolverDialog*)getDialog())->updateButtonsState(oEvt.Sel
ected);
        }
}
------------------------------------------------------------
------------


Thanks,

Mikael

As a signed value, this would be "-1", which might
mean that nothing was 
selected...

just a guess.

That's what I've guessed too, but the value I get is always
65535.
That's why I'm wondering about that...

if someone knows another way to know if the action listened
is a
selection or anything else, let me know...

cheers

This smells like a bug where some internal C/C++ unsigned
short 65535 
(corresponding to signed short -1, presumably a special
internal value 
representing "nothing selected") is converted into
a UNO long in a wrong 
way.  You should file an issue.

Is this a 64 bit version, or the standard build?

It's a 32 bit version, I've downloaded the sources from
SRC680_m190 a
few months ago.
