Model Tree Window

The Model Tree window enables you to view and manipulate all items (packages, classes, diagrams, relationships, and so on) in the UModel project.

um_default_packages

Model Tree window

When you create a new UModel project, two packages are available by default, the "Root" and "Component View" packages. These two packages are the only ones that cannot be renamed or deleted. The "Root" package serves as starting point for modeling all other elements, while the "Component View" package is required for code engineering.

 

You can create additional packages, classes, diagrams, and their hierarchy either from this window or directly from a diagram, see Creating Elements. For additional operations that you can take against items in the Model Tree, see the How to Model... chapter.

 

Note:UModel includes several example projects that you can explore in order to learn the modeling basics and the graphical user interface. These can be found at the following path: C:\Users\<username>\Documents\Altova\UModel2019\UModelExamples.

 

Showing, hiding, and sorting items in the Model Tree

To configure what should be displayed in the Model Tree window, as well as the sorting options, right-click inside the window, and then select the required menu option. To view all actions that can be taken against items displayed in the Model Tree window, right-click the item and observe the context menu options.

 

Collapsing and expanding items in the Model Tree

To expand items (for example, packages) in the Model Tree window:

 

Press the * (asterisk) key to expand the current item and all child items
Press the + (plus) key to expand the current item only.

 

To collapse the packages, press the - (dash) keyboard key. To collapse all items, click the "Root" package and press - (dash). Note that you can use both the standard keyboard keys and the numeric keypad keys to achieve this.

 

Identifying active diagram items

When a diagram is open in the Diagram pane, the Model Tree window shows some items with a light-blue dot at their base. These are items that are displayed in the active diagram (like "BankView" and "Java Profile" in the example below):

Icon reference

The Model Tree window may display a large number of icons which correspond to elements and diagrams in your project, the code engineering packages, as well as the imported profiles or subprojects. Specifically, it may display the following package types:
