Configuring Views and Context 113

Configuring Views

Additional Context group for the current view or page. If a context has been set by some

view, it can be used in other views by declaring it in that view’s context.

Context Inputs

If the context of a page has been set, then a view can use that value by specifying the

named value of the context. For example, the Host page has set its current host into the

context using the key

Host. The Event Summary for Host view uses that context by

setting its context input (the expected context value) to use Host as its key.

Similarly, if a page has a given named value in its context, and a link takes it to another

page, then that new page can get access to that value by specifying its name as a context

input.

Context can be passed when moving from one page to another. For example, click on a

link in the Host Monitor with Host Detail view, and the Host Browser page is displayed

with data for the same host. In this case, the Host Browser page expects that:

• a list of Host data objects is required (hosts context)

• a specific Host data object may be provided (internal context input)

The host is set in the Context Inputs section.

If a view is not passed the required context input, it uses the page’s context.

Additional Context

Additional Context for a view allows you to set values on context keys for the view to

use. If it is a container view, the additional information is used by its children.

Outputs (Global Context Mappings)

Some components may generate context values based on actions that the user performs

on the component. These are listed in Global Generated Contexts in the reference page

for the component. You can use this section of the Context editor to define a key for one

or more of these context outputs if you need that information in a dependent view.

Configuration Tab

Configuration properties are those that control the overall look of the component and

where the component gets its data. For instance, in a Splitter you can control whether

the split is horizontal or vertical. In a simple component like a Label, two important

configuration properties are the label text and background color. In a complex
