MATLAB: In GUI, I have a push button. I want that when this push button is pressed a text file which created before opens automatically without choosing a file..

gui

% I have a textfile which name is readme.txt Its directory: C//matlabcodes folder

%In GUI, I also have a push button. When I press this push button, I want to open "readme.txt" automatically.

thanks in advance

In pushbutton callback,

text=fileread('C:\.....\readme.txt');

set(handles.text1,'String',text)

Hi,

You can try this

 function pushbutton1_Callback(hObject, eventdata, handles)
% operation 1 here
 guidata(hObject, handles);

 function pushbutton2_Callback(hObject, eventdata, handles)
% operation 2 here
guidata(hObject, handles);

Operation 1 is performed only on click of pushbutton1 and Operation 2 is performed only on click of pushbutton2
