Order of code execution seems weird

I have built an app that executes long functions. In my GUI I have something like a MessageWindow (Colored-Edit-Field). When clicking a button to calculate something that takes a while I want to show a Message like: "LOADING. . ." The according code is shown below.

When I execute the code by clicking the button, the Message is not shown. The calculation function ist executed though.

When I step through my code with the debugger line by line, it works fine. So for me it seems like MATLAB ist not executing the code in the correct order. Can somone explain me what the problem could be here?

%% Function in app.PlotSetup
function printProcess(app, message)
            app.StatusEditField.BackgroundColor = app.yellow;
            app.StatusEditField.Value = message;
end

%% Code in app.Plotting
% Function to show message
printProcess(app.PlotSetup, "LOADING WITH SELECTED PARAMETERS...")

% Big calculation function
continueImportProcess(app.PlotSetup)

Would it be possible for you to make a self contained example that reproduces the problem and attach it?

Try calling DRAWNOW after setting the editfield values.

Thanks! Works perfectly.

%% Function in app.PlotSetup
function printProcess(app, message)
app.StatusEditField.BackgroundColor = app.yellow;
app.StatusEditField.Value = message;
drawnow % force GUI to refresh
end
