r = mui.DoMethod(id$, method$, ...)
The methods that you can use with this function depend on the class of the specified MUI object. Have a look at the class reference to see what methods are supported by the different MUI classes.
Also, the arguments that you have to pass to this function after the method name depend on the method. They are different for every method. The same is true for return values. Some methods return values, some do not. Please refer to the class reference to see which arguments your method requires and whether there are return values for your method.
