回答： ES 2019-4-17

I designed a GUI in appdesigner where I can bush the button LOAD to load a file directly from my desktop. But I want the name of the file to appear in the Edit field. Is there anyway i can do it? I am new to appdesigner

Thank you

%% function for the load button.

function LOADButtonPushed(app, event)

[file,~] = uigetfile(['*.mat'],'Load File','MultiSelect', 'off');

if isequal(file,0)

disp('Nothing Selected')

else

try

app.Data = load(file);

Timestep= app.Data.Profile(1,:);

Power = app.Data.Profile(2,:);

plot(app.UIAxes,Timestep,Power)

catch

errordlg(['There was a problem loading the .mat',' file'],'Load Error!');

return;

disp(['User selected ',file]);

end

%% function for the EditField

function PROFILENAMEEditFieldValueChanged(app, event)

app.Data= app.PROFILENAMEEditField.Value

You have to update the edit field value from the callback of the load button.

%% function for the load button.
function LOADButtonPushed(app, event)
            [file,~] = uigetfile(['*.mat'],'Load File','MultiSelect', 'off');
            if isequal(file,0)
                disp('Nothing Selected')
            else
              
               try
                   app.Data = load(file);
                   Timestep= app.Data.Profile(1,:);
                   Power = app.Data.Profile(2,:);
                   plot(app.UIAxes,Timestep,Power)
                   app.PROFILENAMEEditField.Value = file;% Set the file name here
              catch 
                    errordlg(['There was a problem loading the .mat',' file'],'Load Error!');
                    return;
               disp(['User selected ',file]);
               end
            end
