The components and2 and or2 are logic gates. Each one takes two inputs and has one output...
and2 works like this:

if either one is off, out is off ?

Yep

or2 works like this:
if input0 OR input1 is on then the output is on.

this i get lost, as i understand this. if either is ON,
then out is ON. but at least ONE will be on at all times.
so it would stay ON ? and ya'll talk about input/output,
i don't see(mentally) what's going "which" way when i press
the button. i understand when i click the button it will turn on
or off. but this wiring(logic) gets me. but i'll keep fighten
Thanks !!!!!!

That is also correct with the or2 if either input is on then the output is on.

Each component will have pins that you can connect appropriate things to. In the case of the or2 component you have three pins

or2.n.in0
or2.n.in1
or2.n.out

so you have two inputs and one output... if you have the output from a pyvcp button connected to or2.n.in0 and press the button the or2.out will be on as long as one of the in's are on.

John

is there a reset in <ngcsub> which is called but not part of that file?

I am not sure I really understand your question, but the "time" component does have three u32 outputs. You should be able to connect those to Glade
According to www.linuxcnc.org/docview/devel/html/gui/...l#gladevcp:HAL_Label
You would need to set the type to 2 and choose a suitable format specifier. For time values I would try "%02i" I think.
Python format strings are a subject all of their own:
docs.python.org/release/2.5.2/lib/typesseq-strings.html (which I feel could be more clearly written)

Put the words "show pin" right at the start of your postgui HAL file. That will list all the pins that exist at that point into dmesg.
Then you can see what the Glade pins are really called.
