On the 18th September we are organizing the first Belgian EA User group event in Brussels.

This event, that will take a whole day, will feature three English speaking tracks with presentations from many Enterprise Architect and IT industry experts such as Sander Hoogendoorn, Phil Chudley, Peter Doomen and myself of course.

Meet your fellow EA users, share your EA user experiences and learn new or better ways to use Enterprise Architect.

With EA-Matic you can develop add-ins for Enterprise Architect using the built-in scripting feature of EA.

With this EA-Matic script you can configure your own default line-styles depending on the type of connector.

In Enterprise Architect you can choose from no less then 9 different line style for the connectors.

Line Styles

Unfortunately you can only choose from the first three to be the default line style for new connectors.

Additionally you can also specify the default for Generalization to be Tree Style.… Read more

With EA-Matic you can develop add-ins for Enterprise Architect using the built-in scripting feature of EA.

This example EA-Matic script keeps the signature of the overriding operations in sync with the signature of the overridden operation.

This is especially useful when you are modelling an interface and a number of classes that realize this interface. EA has this neat feature Overrides and Implementations accessed by Ctrl-Shift-O to copy operations from an interface or superclass to the realizing/specializing class.

EA-Matic Overides and Implmentations

This works great when you have created a new operation, or added a new realizing class, but once you change the signature of your interface operation you are on your own.… Read more

With EA-Matic you can develop add-ins for Enterprise Architect using the built-in scripting feature of EA.

This example EA-Matic script keeps the names of objects synchronized with the name of their classifier.

When modelling with objects the name of the object is often left empty because it doesn’t have any significance at that point. One of the downsides of this practice is that in things like the traceability view, or in the links view the object shows up without a name, which of course doesn’t help much.… Read more

With EA-Matic you can develop add-ins for Enterprise Architect using the built-in scripting feature of EA.

This example shows how to make diagrams that maintain themselves to make sure they are always up-to-date.

The idea is that we want a diagram that shows all the relations of the owning object. The diagram should always be up-to-date without manual intervention.

EA-Matic auto_diagram

To indicate that this diagram is an automatic diagram we nest it under the class and prefix it with AUTO_ and on the diagram we place the owning object and its related elements

With EA-Matic you can develop add-ins for Enterprise Architect using the built-in scripting feature of EA.

This example shows how you can prevent deleting elements that are still being used as a type in either an attribute or parameter.

The script uses the EA_OnPreDeleteElement event to first check whether the element is not still used.

If an attribute using this element as type is found then the element is not deleted and the user is informed with a messagebox.

EA-Matic cannot delete attribute

If it isn’t used as attribute but is used as a type in a parameter or the return type of an operation you get the following messagebox:

EA-Matic cannot delete parameter

With EA-Matic you can develop add-ins for Enterprise Architect using the built-in scripting feature of EA.

This example shows how to use the add-in menu to add your own menu and menu option, and react to the user clicking such a menu option.

With this script you can use menu options as a regular add-in would

EA-Matic Menu in Action

Download the complete script: EA-Matic MenuHandling

Step 1: defining the menu

'EA-Matic
'Tell EA what the menu options should be
function EA_GetMenuItems(MenuLocation, MenuName)
	if MenuName = "" then
		'Menu Header
		EA_GetMenuItems = "-&MyAddinMenu"
	else
		if MenuName = "-&MyAddinMenu" then
			'Menu items
			Dim menuItems(1)
			 menuItems(0) = "TreeViewMenu"
			 menuItems(1) = "DiagramMenu"
			 EA_GetMenuItems = menuItems
		 end if
	end if
end function

Step 2: define the menu state

'Define the state of the menu options
function EA_GetMenuState(MenuLocation, MenuName, ItemName, IsEnabled, IsChecked)
	if MenuName = "-&MyAddinMenu" then
		Select Case ItemName
			case "TreeViewMenu"
				if MenuLocation = "TreeView" then
					IsEnabled = true
				else
					IsEnabled = false
				end if
			case "DiagramMenu"
				if MenuLocation = "Diagram" then
					IsEnabled = true
				else
					IsEnabled = false
				end if
		end select
	end if
	'to return out parameter values we should return an array with all parameters
	EA_GetMenuState = Array(MenuLocation, MenuName, ItemName, IsEnabled, IsChecked)
end function

Step 3: React to user clicking a menu option

'react to user clicking a menu option
function EA_MenuClick(MenuLocation, MenuName, ItemName)
	 	if MenuName = "-&MyAddinMenu" then
		Select Case ItemName
			case "TreeViewMenu"
				Dim Package
				Set Package = Repository.GetTreeSelectedPackage()

Since I started writing the EA Navigator and other tools the code has been open source and available on Github. The code is split up in a tool-specific part for the EA Navigator and some other tools, and a framework that can be used to build your own tool.

 Downloading

The code for the framework and the tools is published on GitHub, a version control repository “in the cloud”, which is free for public repositories. The easiest way to download the code is to install GitHub for Windows.… Read more

On the 5th of February 2014 there’s a new EA User Group event in Utrecht in the Netherlands

Enterprise Architect

I will be doing a demonstration of how you can actually create an EA add-in in 10 minutes, based on the Tutorial on this blog.

Below the full agenda of the event.
For more details and booking visit http://eausergroup.com/

I’m looking forward to meeting all of you there.

Agenda Utrecht

The main new feature of the version 2.4 of the EA Navigator is the Quicksearch. The Quicksearch feature is undoubtedly the fastest way to find anything in a (large) EA model. It is the type of feature which makes you wonder how you could live without it all that time before.

Developing the Quicksearch function was far from easy. I wanted something that resembles what Google does when you start typing, and I started things with a standard Windows Forms ComboBox.… Read more
