Hi Scott,
Yes, you can specify which parameter is available to the user to edit for custom blocks by creating a mask for your block. To create a mask for your block,:
- Firstly open your custom block in Simulink.
- From the block's context menu, select Mask > Create Mask. This opens the Mask Editor.
- In the Mask Editor, you can add mask parameters by clicking the Add button in the Parameters tab. You can then set the parameter properties, including the prompt string, data type, and default value.
- To make a parameter editable in the block's Quick Insert dialog, you need to set its Prompt field to a non-empty string. This will enable users to enter a value for that parameter in the Quick Insert dialog.
To disable the text entry field for a block, you can remove the prompt string for all mask parameters in the Mask Editor. Alternatively, you can set the Block Properties > Mask > Mask Display > Show Parameter Dialog During Simulation option to "off" to prevent the mask dialog from appearing during simulation. Note that this will also prevent users from setting parameter values using the mask dialog during simulation.
