Examining the Flow View

In addition to the Insights feature, KnowledgeKube includes a number of tools to help you analyse your application, and view how its various parts work together. Collectively, these tools are known as the Model Inspector.

At this point we are going introduce the Flow View. Flow View creates a visual abstract of your application, which lets you see how each question group connects with the rest. If there are any groups with no direct connection to any other part of your application, the Flow View interface will also let you see this.

To access Flow View, click the Model Inspector button in the Definition Toolbar.

 

Then, switch to the Flow View tab using the list across the top of the Model Inspector window.

The two question groups we’ve added so far will appear as named rectangles, or Nodes, in the middle of the Flow View panel. An arrow leading from NewAccounts to AccountsSummary indicates a connection between the two groups (using ShowForm, for example), and which way the connection flows.

The order in which nodes appear inside the Flow View panel is not fixed, which means that your NewAccounts node may appear on the left, with the arrow pointing from left-to-right. This doesn't mean you've done anything wrong - as long as the arrow flows from NewAccounts to AccountsSummary, you don't have to worry exactly where the nodes appear.

The fact the arrow is one-way shows that while you can access the summary from NewAccounts, there is presently no way of returning to NewAccounts.

As you add more content to your application, you will notice that certain types of object in your Flow View have different shapes and colours to distinguish them from regular question groups. The Startup Group, for example, is coloured green. You will learn more about the Startup Group and other types of content in later courses and content modules.

If any of your connections are invalid, for example if you spell the name of a group incorrectly when writing a ShowForm function call, the Flow View will still indicate what you’re trying to link to, albeit in a different colour to indicate there is a problem.

 

If a question group is not currently connected to any other groups in your model, it is known as an Orphaned item. These nodes will be labelled as orphaned in the main window. You can view a complete list of orphaned items by selecting the Orphaned Items panel in the Flow View's tab.

 

Double-clicking any of the nodes in Flow View, or any of the orphaned groups in the list, will switch the view to highlight the selected group in your application’s Designer Grid.

You can also save a copy of the graph using the Export function.

 

This lets you save a copy of the graph as either a bitmap image (.jpg, .bmp, .gif, .png) or a vector (.wmf, .emf). You can choose whether to save the flow of your entire model, or just what is currently visible in the Flow View panel. This feature is useful for creating snapshots of your model that you can refer back to later.

Although Flow View doesn’t contain much content at the moment, it will become invaluable as you continue to develop your application, letting you easily keep track of how your content fits together.
