Ämne: Re: [Oorexx-users] ListView CheckBoxChanged event
You can then skip the CheckboxChanged event Connection, looks like you want to
eat the cake and also keep it :-)
If not an event, how will you know when the checkbox for -ALL- is
checked/unchecked, maybe we need some more details what will happen after the
un/checkings

Ämne: Re: [Oorexx-users] ListView CheckBoxChanged event
Well, I had that in mind but I think that once connect-event is done then there
is no disconnect-event that can be used while 'flipping' check-all between on
and off (more than once). I think my issue can be solved if the check methods
are not treated as events, which IMHO they are not.

May I suggest you create a "toogle" button instead, that checks/uncheck the
checkboxes.
I had a "similar" problem, in my case the solution was to fill the list Before
connecting the Event, if I recall it correct.

Ämne: Re: [Oorexx-users] ListView CheckBoxChanged event
Mark, I understand quite well that you don't understand because I didn't
express myself well at all. I'll have another go:
I've got a listview defined with the CHECKBOXES style. I've chosen to insert a
first row -ALL- that when checked should cause all rows to be checked, and if
unchecked all rows should be unchecked. I've implemented the onCheckBoxChanged
event and there I test if the first row is checked/unchecked, in which case I
call the (un)checkAll method (within the event handler) to set the check marks
accordingly. But I can't get this to work and I assume it's because the event
handler gets invoked from itself this way and as it runs unguarded the results
are unpredictable more or less. So my question is: because (un)check(All) are
invoked under program control, i.e. the user is not causing the events, it
seems natural if the event handler is NOT invoked under those circumstances,
the programmer already has full control of what's going on anyway, hopefully ;)
So my suggestion is that these methods don't trigger these events, as they
really are no 'events' as such.
I hope this helps.

Experience some strange behaviour it seems like the ListView (un)checkAll

Without even looking at the code I would say yes that is true.
Is it really necessary? I would say yes, that is what connecting the event is
for. If you don't want the event, don't connect it.
Maybe there is something I don't understand about the question?
