Questions on Xontrol--How to update the state and data

[McArthur]

Hello, everyone. I am new to use the XControl. I don't understand how the program in the facade update the "state" and "Data" after we click the button. I cannot do that, please give me some help on the XControl.

My vi is in the attachment.

Several things don't make a lot of sense. I would recommend you study the shipping example (look for dual mode thermometer in the example finder).

• You seem to not even use the "data", but increment the "state". Wouldn't it be more reasonable to use the data?
• There is a primitive for "+1", no need for the "1" diagram constant.
• You seem to work with integers, so use an integer (blue) numeric instead of floating point (orange) representation for the data.
• When you modify data or state, you need to update the action cluster to indicate that fact.
• Your boolean button terminals should be inside their respective events so they properly get read and reset.
• I would use "value changed" instead of "mouse up" events.

Can you explain in a few words what the xcontrol is supposed to do. What is the functionality?

Looking at the code gives no real obvious hints to me. 😉

You should set the Action.State Changed? boolean:

Thank you both of you!

The example is just a dummy, not really make sense.

Now I understand the reason why the state can not update, because I didn't do as TCPlomp mentioned. It seems working now....

 I mentioned this too, however without a pretty picture. 😉

The example is really quite good and shows these things too as well as many other important points. Please try to fully understand it. 

I would strongly advise you to also look at my other suggestions. You still haven't explained the purpose of the xcontrol. I am still curious. 😉

Thank you both of you, altenbach! I mentioned about you.

Yes, the other points are very good. Thank you very much....
