Hello all,
It seems trivial, but I have apparently forgotten how to get EA to show constructor/destructors on class diagrams. I actually have a model stub that shows them, but all my new classes do not, even though they show any other operations and attributes I create for the class. So three questions:
1. How to get constructor displayed on class diagrams.
2. Why would EA not show them by default?
3. Where could I have found the answer to this in the so-called 'Help' documentation.
Thanks in advance.

You can only show them if you have defined them as operation. To show the operations compartment check the diagram properties: Elements/Operations.

Hi
There is an option the settings for code engineering that specifies if a constructor/destructor is generated when code for the class is generated.
Reverse engineering will the of course add the operations to you class

SomersetGraham,
Yes, the approach you suggested works. Thank you. Not sure what Sparx is thinking here. It sure seems to me to be a convoluted, roundabout, non-intuitive approach to what would arguably be a primary usage of the tool.
Anyway, thanks again.

Well the code generation only makes a default constructor which is not always what you want
You can define more constructors using the operations page

I agree, but not every OO language has a constructor. For example Python (supported by EA) has initializers which are similar but not identical to C++ constructors. Initializers in Python are intuitively an operation (self exists and gets extended with attributes). It is not so intuitive to think of constructors as operations but really they are: they are just a way to setup the initial state of the instance, and there can be many (overloads) of them (which emphasizes that an operation is the right way to think about a constructor).
