Most of the screens in your application, there contents and flow to other screen are typically driven by the use cases you write. It helps to model the screens using UML notation so you can describe each element and model how each element links or depends on other elements. Once the elements are in a UML model you could also show interaction e.g. an actor clicking a button which instigates a business object function which then builds a list box and populates a text box, and then enables another button.
Enterprise Architect is an excellent low priced modelling package, however whilst it provides many useful features and powerful forward and reverse engineering options ( it even includes a debugger which can auto generate sequence diagram based on a run through code ), it also provides great extensibility through the add in interface. In the previous post I discussed an addin I wrote to reverse engineer the UML model from various web page files, however this addin works differently by using a spy++ type capture pointer. The user only needs to hover the pointer over a window they need to capture, the addin then creates a UML model of the dialog using all the component parts of the window, with the exact same size and position as they appear on screen.
Thanks to Mark Belles for writing the windows capture code which provides the hover utility to obtain a window handle. From this it was a simple matter of extracting all the windows information using the Win32 API. The add in also should also provide a good template for anyone else writing one and contains supporting classes that help wrap the unmanaged EA interfaces.
The screen below shows the EA options dialog
When you start the add in through EA you are presented with the following dialog
The UML diagram below then gets generated.
Although the output isn't perfect it's a lot more productive than creating all yours screens manually. Not a job Id want to do often :)
The full source code to the add in written in C# is available in the EA WIKI, I hope you find this useful.
