How Can I Design a Custom Simulink Mask with Dual-List Data Selection Similar to a Bus Selector Block in MATLAB R2022b?

I'm working on a Simulink project in MATLAB R2022b and I need to create a custom mask that functions similarly to the Bus Selector block. However, I want to enhance the user experience by implementing a dual-list data selection feature. This would allow users to easily select data elements from one list (the source list) and move their selections to another list (the destination list), configuring the block's output dynamically.

 

I'm looking for guidance on how to:

1. Create a custom mask in Simulink that integrates this dual-list selection mechanism.
2. Ensure that the mask interface is user-friendly and allows for efficient management of data elements between the two lists.
3. Implement the functionality so that it is compatible with the features and updates in MATLAB R2022b.

Could anyone provide a step-by-step tutorial or point me to resources that could help me achieve this? Any tips on best practices for creating such interactive Simulink masks would also be greatly appreciated.

To design a custom Simulink mask with a dual-list data selection feature similar to a Bus Selector block in MATLAB R2022b, you can utilize the Simulink.dialog.ListboxControl class for list boxes and the Simulink.dialog.Button class for interactive buttons. This setup allows for a mask interface where users can select data elements from one list and add them to another, enhancing the data selection process without removing items from the source list.

In the provided example, the mask includes:

1. Listbox Controls: Two listbox controls are implemented, one displaying the available data items (source list) and another for the user-selected items (destination list).
2. Select Button: A "Select" button enables users to add selected items from the source list to the destination list. The callback for this button ensures that items are not duplicated in the destination list and updates the list to reflect the user's selections.
3. Remove Button: A "Remove" button gives users the ability to delete items from the destination list. Its callback updates the destination list and disables the "Remove" button if the list is emptied as a result of the removal.

This example demonstrates how you can create a Simulink mask that facilitates the efficient selection and addition of data elements to a destination list, thus improving the data management capabilities within your Simulink model.
