====== 01 Overview ======

This application template showcases our //UI framework// for applications with graphical user interfaces. We use this template as a container which **loads the project-specific DQMH modules dynamically** from a configuration file.

{{:code:dqmh:hse-application-template:pasted:20210305-110517.png}}
===== UI Framework =====

The //UI framework// helps us with:

  * reusing UI management code
  * project-specific UI layouts
  * displaying a fancy splash screen
  * populating the Runtime Menu dynamically 
  * populating a navigation module dynamically 
  * generating an event log for debugging

...and much more!

The //UI framework// is built on top of the [[code:open-source:hse-libraries|HSE Libraries]] and consists of a collection of DQMH modules and a few helper VIs.

==== Framework Modules ====

These DQMH modules are designed to be reused, hence they are generic and not part of the project-specific code of an application:

  * [[code:open-source:hse-framework:event-manager|Event Manager]]
  * [[code:open-source:hse-framework:ui-manager|UI Manager]]
  * [[code:open-source:hse-framework:navigation|Navigation]]


==== Framework VIs ====

In order to dynamically load DQMH modules and to achieve some of the //UI framework// functionality, the following VIs are part of the framework, too:

=== Startup VI ===

The ''/startup.vi'' is used to run the application. It...

  * shows a splash screen
  * reads the main configuration (containing the list of modules to load)
  * loads the UI Manager and the Event Manager modules
  * loads a list of project modules (no static linkage)
  * calls the "configure" requests of all the modules
  * displays the front panel of the ''UI Manager'' module 

=== Project VIs ===

These are project-related or project-specific VIs that are supplied by the //UI Framework// but can or have to be modified for each project.

  * ''/Project/Project.lvlib'': Contains the project-specific VIs
  * ''/Project/PROJECT_InitLogging.vi'': Starts the hse-logger
  * ''/Project/PROJECT_Name--constant.vi'': Name of the project
  * ''/Project/PROJECT_RunTimeMenu.rtm'': Run-Time Menu for the application
  * ''/Project/PROJECT_SplashScreen.vi'': Splash Screen
  * ''/Project/PROJECT_StartupSteps.ctl'': List of steps for the startup.vi to execute
  * ''/Project/PROJECT_UserCredentials.vi'': List of users for the built-in login feature

===== Project-Specific DQMH Modules =====

In order for DQMH modules to be compatible with our application template, these modules need to implement our [[kb:labview-frameworks:dqmh:hse-flavour|HSE DQMH flavour]].
