How to apply/check changes in a Simulink Mask via callback?

Hello,

At the moment i am going to set up Simulink block mask, which is changing the content of popup elements due to entries inside an edit field. Therefore I need to know, how to "press" the Apply button of the Mask-GUI via script, respectively how to check if the GUI has unapplied changes.

I am using Matlab Simulink 2013b.

Thanks in advance, Bjoern

A bit late but maybe this helps somebody:

selected_block_handle = get_param(gcb,'Handle');
dlgs = DAStudio.ToolRoot.getOpenDialogs;
for i=1:length(dlgs) %find dialog of selected block
    if class(dlgs(i).getSource) == "Simulink.SLDialogSource"
        dialog_block_handle = dlgs(i).getSource.getBlock.Handle;
        if dialog_block_handle == selected_block_handle
            dlgs(i).apply %'click' apply
        end
    end
end

Hi Bjoern,

when the user presses enter after editing the field, the MaskCallback is executed. This is the callback in which you should validate what the user entered (and do the manipulations you describe).

Hi Titus, thanks for the fast answer. This is exactly what I am doing and inside this callback I would like to call the function which is behind the mask "Apply" button (most bottom right), respectively to check if the GUI has unapplied changes.

But i do not know the function calls.

thank you Björn Bobe, it worked for me.

HI Bjorn,

The way you can do this is save your model in MATLAB before running the model:

save_system('Autonomous_Dynamic_Model_Sim3');

This solution didn't work for me. Even pressing 'save' in Simulink didn't solve it. I had to manually go into the model and find the block I had edited and press the 'Apply' button. Then it would run from MATLAB.
