===== 'System Message' =====

> Sends a HSE-generic broadcast message, consisting of an Identifier, a variant Payload and Source information.

  * Provides a generic way of broadcasting information
  * Allows for dynamic registering and triggering of broadcast events

{{code:dqmh:sysmsg-cluster.png?|}}

  * string ''Identifier''
  * variant ''Payload''
  * enum ''Source Type'' (module, application, network)
    * the typedef can be found in ''hse-libraries/hse-dqmh.lvlib/Templates and Controls/System Message Source.ctl''
  * string ''Source Name'' (Module Name)
    * for clones, the Clone ID is appended to the Module Name

==== Message Types ====

=== Ready for Display ===

Lets the UI Manager know that a module identified by <b>Main VI Reference</b> wants to be displayed in the content subpanel.

Optional: "Title" specifies the string to be displayed in the Title indicator of Layout VI

Optional: "Target SP Name" defines the subpanel in which to display the module.

=== Removed from Subpanel ===

Sent from UI Manager's  "Load Module into Subpanel" MHL case, lets the application know that a module has been removed from the subpanel it was shown in.

=== Startup Completed ===

Lets the UI Manager know that the startup phase of the whole application (ie anything that should happen before the splash screen is hidden and the front panel of UI Manager is shown) has completed.

UI Manager will send the "Startup Completed Received" broadcast, which notifies the startup.vi to wrap up startup phase.

| {{:kb:labview-frameworks:dqmh:hse-flavour:pasted:20260817-155537.png}} |

=== Update Splash Screen Message ===

Updates the Splash Screen of the application with Message and Percentage during the startup phase (i.e. before the "System Message - Startup Completed" has been sent.

UI Manager will send the "Update Splash Screen Message Received" broadcast, which notifies the startup.vi to update the controls on the Splash Screen.

Note: Use percentages between 61% and 99%.
