Creating a new diagram template
Creating a new J profile implementation
Diagram templates, like code templates and documentation templates, are created inside J profile implementations in the "Behavior profiles" folder of a J MDA component. This means that the next step in this quick tour project is to create a J profile implementation inside which you will then create and develop your new diagram template.
To create your new J profile
implementation, select the Behavior profiles folder and click on the 
icon. In the window that then appears, name
the J profile implementation ("MyTemplates") and confirm by
clicking on the OK button.
For more information on creating J profile implementations, please see Defining a J profile implementation.
Creating a new diagram template
To create your new diagram template,
select the MyTemplates J profile
implementation you have just created, click on the 
icon and click on OK to confirm. The Select
diagram type window then appears. Select Class and click on the OK
button.
Figure 63. The Select diagram type window
The Diagram template creation window then appears.
Note: Diagram templates can only be created on J profile implementations in J MDA components. It is not possible to create a diagram template for a Java MDA component.
For the purposes of our example, we are going to change the name of the diagram template we have just created, by carrying out the following steps:
1. Select the name of the diagram template on the top left of the window shown in Figure 64.
2. Click once on it (or press F2).
3. Enter the new name (in our example, Static diagram template) for the diagram template.
Note: This operation can also be carried out in the MDA Modeler explorer.

Defining the diagram naming rule
To define the rule that will be used to name new diagrams created through the new diagram template, the Naming rules property is used (Figure 65).
Figure 65. Defining the Naming rules property for your diagram template
Steps:
1. Select the new diagram template on the left of the window.
2. In the list of properties on the right of the window, select the Naming rules property and double-click in the Value column to activate the field. Enter "Project diagram - " + Name (please make sure you enter this exact text, since any text which is not J code has to be surrounded by double quotes). For more information on entering J code, please see Inserting J code.

Creating a navigation node to retrieve classes
We are now going to create a navigation node, which will be used to retrieve the classes of the package and to unmask them in a diagram.
Steps:
1. Select the Static diagram template template root.
2.
Click on the 
icon. The Create a navigation node
window then appears.
3. Select Classes from the list.
4. Click on OK to confirm.

For more information on creating navigation node, please see Creating navigation nodes.
Creating a display node on the Classes navigation node
We will now proceed with the creation of our first display node, which will be created on the Classes navigation node.
This display node allows to specify that the classes will be unmasked in the generated diagram.
Steps:
1. Select the Classes navigation node.
2.
Click on the 
icon.
We are now going to continue by defining the background and foreground colors that will be used for unmasked classes, as shown in Figure 67.
1. Select the display node you have created for the Classes navigation node.
2. Click on the Value column for the Background color property, and enter the color you wish to use for the background of classes: in our example, wheat.
3. Click on the Value column for the Foreground color property, and enter the color you wish to use for the background of classes: in our example, blue.

Creating a navigation node to retrieve attributes
We are now going to create a navigation node inside the Classes navigation node, which will allow us to unmask the attributes belonging to the classes unmasked in a diagram.
Steps:
1. Select the Classes navigation node.
2.
Click on the icon. The Create a navigation node
window then appears.
3. Select Attributes from the list.
4. Click on OK to confirm.
The next step in our quick tour project is to create a filter on the "Attributes" navigation node, to indicate that only attributes with public visibility should be unmasked.
To carry out this operation, select the Attributes navigation node. In the Value column for the Filter property, enter the following: Visibility == Public.
For more information on entering J code, please see Inserting J code.

For more information on creating navigation node, please see Creating navigation nodes and Filters.
Creating a display node on the Attributes navigation node
We will now proceed with the creation of our second display node, which will be created on the Attributes navigation node.
This display node allows to specify that the attributes will be unmasked in the generated diagram.
Steps:
1. Select the Attributes navigation node.
2.
Click on the icon.
We are now going to continue by defining the foreground color that will be used for unmasked attributes, and by indicating that we wish to have detailed visibility and the signature of these attributes, as shown in Figure 69.
Note: Detailed visibility for attributes means that they are displayed with their visibility symbols (+, - and #).
1. Select the display node you have created for the Attributes navigation node.
2. Click on the Value column for the Foreground color property, and enter the color you wish to use for the font color of attributes: in our example, violet.
3. Check the tickbox for the Detailed visibility property.
4. Check the tickbox for the Signature property.
