Hi Martin,
To achieve the dynamic enabling and disabling of Edit parameters X and Y in your masked subsystem based on the selection of Popup parameters A and B, you can utilize the Simulink.Mask and Simulink.MaskParameter classes in MATLAB. These classes provide a programmatic way to control mask properties, parameters, and their behaviors.
Here's a step-by-step approach to implement this functionality:
1. Create a Mask Object: First, you need to create an object of the Simulink.Mask class for your subsystem block. This is done using the Simulink.Mask.create method. For example:
maskObj = Simulink.Mask.create('yourSubsystemBlockPath');
2. Add Popup Parameter: Add the Popup parameter (A and B options) to your mask using the addParameter method of the mask object. For instance:
maskObj.addParameter('Type', 'popup', 'Name', 'PopupParam', 'Prompt', 'Select Option', 'TypeOptions', {'A', 'B'});
3. Add Edit Parameters X and Y: Similarly, add the Edit parameters X and Y to your mask.
maskObj.addParameter('Type', 'edit', 'Name', 'X', 'Prompt', 'Parameter X');
maskObj.addParameter('Type', 'edit', 'Name', 'Y', 'Prompt', 'Parameter Y');
4. Use Callback for Dynamic Behavior: To make parameters X and Y enable or disable dynamically, use the Callback property of the Popup parameter. This property allows you to specify MATLAB code that executes when the Popup parameter value changes.
popupParam = maskObj.getParameter('PopupParam');
popupParam.Callback = 'dynamicEnableDisable(gcb, get_param(gcb, ''PopupParam''))';
5. Define the Callback Function: In your model file or a separate script, define the dynamicEnableDisable function that enables or disables parameters X and Y based on the Popup selection.
function dynamicEnableDisable(block, popupValue)
switch popupValue
case 'A'
set_param([block '/X'], 'Enabled', 'off');
set_param([block '/Y'], 'Enabled', 'on');
case 'B'
set_param([block '/X'], 'Enabled', 'on');
set_param([block '/Y'], 'Enabled', 'off');
end
end
This function uses the set_param command to set the Enabled property of parameters X and Y based on the Popup parameter's value.
6. Apply and Test: Save your changes and test the subsystem mask. The Edit parameters X and Y should now be dynamically enabled or disabled based on the Popup parameter selection.
Remember, this approach uses MATLAB code to programmatically control the mask parameters and their behaviors, thus providing a more dynamic interaction within the mask dialog of your subsystem.
