Offloading Callback Execution to a Background Pool

Overview

This demo shows how to use "backgroundPool" within App Designer to separate a callback execution from the app's thread.

How to run this demo

To see the use of "backgroundPool" proceed as follows:

• Run the "Parallel App" (e.g., via the project shortcut);
• Press the "Start Simulation" button;
• Wait a couple of seconds;
• Press the "Generate Random Data" button.

In this case, the table data is updated in a separate thread and the simulation does not pause.

To compare with a case where the callback is not offloaded to a new thread follow the steps below:

• Run the "Series App" (e.g., via the project shortcut);
• Press the "Start Simulation" button;
• Wait a couple of seconds;
• Press the "Generate Random Data" button.

In this other case, updating the table will temporarily stop the simulation execution since the callback is executed within the app.

The code for boths apps can be inspected in App Designer.
