How do I create an enum typedef?

[VI_Joe]

I want to create an enum typedef?  I should be able to right click on the enum and select "Advanced" from the drop-down menu.  However, when I do that, "Advanced" is greyed-out.  What should I do?

Thanks in advance.

Select the control then click "Customize Control..." in the Edit menu.

Prequil to Jim's reply...

-1 ) Right-click on the enum constant and select "Change to Control"

0) Switch to the front panel

Continue with Jim's instruction.

Explanation: The "customize" option is not available for non-type def'd enum constants on the diagram.

PS: Jim, I like your poem.

The instructions given worked for me.  Thanks so much! 

However, this brings up another related question.  When I open the Standard State Machine template, there's a Beginning State typedef and a Next State typedef.  When I double click on either, nothing shows up on the front panel.  Can you explain what's different?

They are constants on your block diagram. They have no representation on the front panel.

You can right-click them as well and select 'Open Type Def' or 'Advanced -> Customize'.

This was the nature of my original question in this tread.  When I create a constant enum, I can't make a typdef out of it because the menu items that would normally be used are greyed out.

Joe,

It is simple theory.

You can have 'N' no. of constant instances for a Typedef Enum variable; but not 'N' no. of variable instances for a Enum constant. Thats why, the menu items are normally greyed out for an Enum constant.

I'm sorry, I still don't get it.  Can you explain the steps I would have to go thru to duplicate the Beginning State or Next State typdefs from the Standard State Machine template?

Joe,

See Ben's reply. It has already got the answer you want...

I realize this thread is old, but for anyone else like myself who comes acorss this in the future, I believe Ben missed a step at the end to create a type def like the ones used for a state machine.

Once the custom control front panel is opened after selecting customize controls, select whether you want a type def or a strict type def from the drop down menu at the top.

When you then go to your block diagram and switch the control to a constant, you can right-click on it and see the option to open type def.
