When loading a model using 'load_system', simulink is opened in the background. When adding a subsystem (using the API) to the loaded model, the simulink remains in the background (so far so good). However if you add, for example, a state to a stateflow block (using the API again), simulink pops up to the foreground. To make things worse, the window is activated every time a new state is added.

How to prevent simulink to go to the foreground when sending these types of commands?

Stateflow chart is sometimes treated differently than a subsystem. Can you contact the Mathworks tech support with a simplified script and see what they say?

Tech support should be active on these forums as well. An example scipt is a good idea :) :

ns = new_system('example');
load_system(ns);
add_block('sflib/Chart', 'example/sf');
rt = sfroot;
top=rt.find('-isa', 'Simulink.BlockDiagram','-and', 'Name', 'example');
sfChart = top.find('-isa','Stateflow.Chart','-and','Path','example/sf');
newState=Stateflow.State(sfChart);
newState.Name='newState';
% Next statement will open the simulink window:
newState.IsSubchart=1;

Maybe, it is dependent on how you program it? The following example doesn't show the model until the last line.

bdclose all;
ns = new_system('example');
add_block('sflib/Chart', 'example/sf');
rt = sfroot;
m = rt.find('-isa','Stateflow.Machine');
ch = m.find('-isa','Stateflow.Chart','-and','Name','sf');
sA = Stateflow.State(ch);
sA.Name = 'A';
sA.Position = [50 50 310 200];
sA1 = Stateflow.State(ch);
sA1.Name = 'A1';
sA1.Position = [80 120 90 60];
sA2 = Stateflow.State(ch);
sA2.Name = 'A2';
sA2.Position = [240 120 90 60];
%% use this to view
set(ns,'Open','On')
