How to show function's result from command window to a "text area or edit field" in app designer ??

4 ビュー (過去 30 日間)
I am creating an application and for that I have developed .m file for my project. This .m file is developed with OOP for keysight signal Analyzer which is working perfectly fine.
Now, I can call my functions from/in the application, but I could now show my results in the text area or edit field in the applicaiton.
Here you can have a bit more idea about it, please take a look. :-
This piece of code is from my .m file:
%! Get the Power of the Marker-1
function Power = get_power(obj, id)
command0 = sprintf(':CALCulate:MARKer%d:Y?', id);
Power = query(obj.interface, command0);
end
And this is the result from Command Window for the given function:
>> obj.get_power(1)
ans =
'-4.83452345E+01'
In App Designer this is what I have tried
% Button pushed function: getMarker'sPowerButton
function get_powerButtonPushed(app, event)
app.obj.get_power(1); % calling function from .m file
end
% Value changed function: PowerTextArea
function TextAreaValueChanged(app, event)
%???????????????????????
end
I have tried many diff. ways to solve it but did'n work out :(
Here is a picture from my design view for proper understanding.
Please help me to show this result(ans) into a text area or edit field.

function get_powerButtonPushed(app, event)
app.PowerTextArea.Value = app.obj.get_power(1);
end
Note that this is the callback function of the pushbutton; the textarea doesn't need a callback function for this.
