MATLAB: Button push status GUI

buttonflagglobalguiMATLABmatlab guipush buttonstatusvaluevariables

Hey,

Is there any possibility to change btn1 value or some sort of it's status when it's pushed?

For example:

I've got 2 pushbuttons btn1 and btn2 in my GUI. When I click btn1 the value/flag/status of itself changes autommaticaly to another value(maybe true/1) so i can use it in my code to do some operations.

Is there any option to do it? Except the global values

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

I actually found the issue. Buy using `handles.ampmin` as name of the variable I was effectively overwriting the `uicontrol` handle thus causing the described behavior. By changing the name of the variable to `handles.ampminvalue`, the behavior changed to the expected one.

MATLAB: H i every one , i need to declare a counter such that if any one of the four buttons is pressed a specefic funtion specified in the fifth button is performed.Suppose UserData can not be used it reserved for something else

Use guidata, which calls setappdata and getappdata internally:

function pushbutton1_Callback(hObject, eventdata, handles)
handles = guidata(hObject);
handles.counter = 1;
guidata(hObject, handles);
% And the same for the other callbacks...
function pushbutton5_Callback(hObject, eventdata, handles)
handles = guidata(hObject);
switch handles.counter
  case 1
  case 2
  case 3
  case 4
  otherwise  % No SWITCH without OTHERWISE
    error('Programming error')
  end
end
