MATLAB: Do I receive warnings when the block masks have numerous entries in Simulink 6.0 (R14)

dialog-typemaskmasksmissingparenthesispopupsimulinkunmatched

If you create a block mask with many entries then the model cannot be reopened without destroying the contents of the block masks. I have created masks with popups containing more than 1500 entries. If the strings used in the popup are long, the above problem arises. I looked for the model file in the text editor. The block masks are written correctly, but OPEN_SYSTEM first throws the following warning:

 Warning: Missing or unmatched parenthesis in mask dialog-type popup specifier.

After that, there are many warning like this:

 Warning: model.mdl, line ###: Subsystem block (mask) does not have a parameter named xyz

It seems to be an overflow while reading the 'MaskStyleString'.

This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

We have verified that there is a bug in Simulink 6.0 (R14) in the way that block masks handle large entries.

There are currently no known workarounds.

MATLAB: Dynamically populating mask parameter popup list

Actually, I figured this out after hours of experimenting with Mask Parameters. This is one way to do it: You can access the 'MaskStyles' parameter like so:-

myMaskStylesVar = get_param(gcb, 'MaskStyles');

Here you should be able to observe the MaskStyles for each of your parameters as edit, checkbox, DataTypeStr, Minimum, Maximum or ...wait for it... popup! Yes, and 'popup' style is defined as follows:-

popup(menuitem1|menuitem2|menuitem3|...etc)

So you can modify the corresponding cell of myMaskStylesVar with the menu items of your choice and set them back as:-

myMaskStylesVar{1} = 'popup(red|green|blue|yellow)'; % Assuming the popup is the first parameter
set_param(gcb, 'MaskStyles', myMaskStylesVar)

You can add this code at any desired callback. In my case, I put it in 'OpenFcn'. However that led to another issue with the Mask Parameters Dialog not being invoked at the end of the code. So I had to do some crude workaround like below to invoke the Mask Parameter Dialog, but at the same time, not lose my precious code above!

a = get_param(gcb, 'OpenFcn');
set_param(gcb, 'OpenFcn', '');
open_system(gcb); %With no OpenFcn defined, this line will call Mask Parameter Dialog
set_param(gcb, 'OpenFcn', a); %Restore your original OpenFcn code

I am 99.99% sure this issue can be handled in a less comical way than above. But it works for me and my boss doesn't complain!! :)

MATLAB: How to obtain the parameters of more than one mask at the same time

Use the following command to get the list of mask parameters of a block:

get_param('model/sub_block', 'DialogParameters')

To get the values of the masked parameters, you may write as folllows:

dialogPrms = get_param('model/sub_block', 'DialogParameters'); 
dialogPrmNames = fieldnames(dialogPrms); % Parameter names 
for idx = 1:numel(dialogPrmNames) 
   dialogPrmValue = get_param('model/sub_block', dialogPrmNames{idx}) % Parameter values 
end
