MATLAB: Stop a mask callback from being called to not display it

callbackmasksimulink

Hello all,
I have a mask subsystem. I saw that the MaskCallback is called when the user double-clicks it.
In that callback i`m checking a variable. Depending on the value I want to open the mask or not.
My problem is that I do not know how to stop the mask from opening.
Any idea is appreciated 🙂
Thanks in advance,
Adrian

Instead of using MaskCallback, you can use blocks OpenFcn callback to implement your requirement. In OpenFcn callback you can decide when to open the Mask dialog.
For example in OpenFcn callback
if Var==TRUE
   open_system(gcbh, 'mask'); % open mask dialog
else
   % Do nothing
end
