CallOptions are used to specify at runtime the transitions, behavior, and position in a call to a particular Panel object.

In some cases you may want the called Panel to appear in another frame and not where the caller is located. In order to do this, you must use the Target option.

This is possible when the Navigation style is Split or Slide, or when Dashboard has control Tab set.
In abstract terms, the Panel adopts the following aspects:

Slide / Split   Tab   Note: The difference between Slide and Split is
if "Left" region is displayed fixed or not.











  Tab1    ...   TabN   

In these cases, the target (or region) will be indicated using its name in the property Target of the CallOptions.
The syntax is:

<Object Name>.CallOptions.Target = TargetName
<Object Name>()


Domain values

The domain of values that the property Target support is given by the list of names of the components on the UI and the names of Navigation Style regions (as is shown above). These values can be defined in two ways:

  • Using bracket notation: A generic way using "[" and "] ".
    • By its target index: Each index references a particular target (e.g. Target[ i ] is the i-th target).
    • By its navigation index: Each index reference a particular navigation target (e.g. <N>[ i ] is the ith target for navigation N).
  • Using alias: It is a relevant navigation value (e.g. Left, Right, Detail, Content, and Center in Slide navigation).

For that reason, there are named equivalence (summarized in the following table)

Synonyms Description
Navegation Target Alias
Slide[1] Target[1] Left It is shown in the left section.
Slide[2] Target[2] Center, Content, Detail It is shown in the central section.
Tab[1] Target[1] N/A It shows the first tab.
... ... ... ...
Tab[K](1) Target[K] N/A It shows the K-th tab.
Split[1] Target[1] Left It is shown on the left side.
Split[2] Target[2] Center, Content, Detail It is shown on the center side.
All N/A Blank It is shown as an independent Panel (as if it were a 'pop-up fullscreen') (2)

    (1) K represents the tabs quantity. 
    (2) Usually, these Panels are not part of the ´content´ of the application (e.g. Settings, About, Help, Login, etc)


  • A Panel called from the left will be displayed on the content region - using call type replace.
  • A Panel called from the content region will be displayed in the same region -using call type push

Other targets










  • When Slide navigation is enabled, a "Right" section is also available.
  • For iOS devices is available a "Bottom" region, independently of the Navigation style used.

The only requirement is that these sections can only be displayed through explicit programming as is explained in the next section.

Triggering programmatically

The Navigation external object allows the developers to show (or hide) content dynamically in the drawer that they want to.

For example, if the application uses Navigation Style = Slide and the central Panel has a user event defined as shown below, not only load the Panel in the right drawer, It also will display the right drawer.

Event 'ShowRight'
      SomePanel.CallOptions.Target = "Right" // Set in which drawer it will be display
      SomePanel()                            // Load the Panel in that target 
      Navigation.ShowTarget("Right")         // Display the target

Special behavior for Android App with Slide Navigation and GAM

When de App main object uses authentication (Integrated security property was set as Authentication) and the App uses Slide Navigation, every called object displayed on the Slide section (default behavior) will also require authentication. Therefore, in case you call an object without integrated security, the Login Object will be shown instead.

For that reason, if you need to call the Register object from the Login Panel (which also has not integrated security), it must be called with Target ‘Blank’, to be shown in an independent Panel. This also applies if you need to call the Login Panel manually.
