how can i have a button in one callback function pause the execution of another callback function
显示 更早的评论

%when this button is pressed i want the code that is executing in
%pushbutton2 to pause

@Joseph Kutteh this question doesn't differ much from the question you asked earlier this week and never replied to:
And it's no surprise that both questions describe the same solution with some minor differences.
How many people do you want working on your problem? Please take some time to learn from the solutions and if you've got follow-up questions, leave comments.

% Initialize in the CreateFcn: handles.Pause = false
function pushbutton1_Callback(hObject, eventdata, handles)
handles.Pause = (hObject.Value == 0);
guidata(hObject, handles);
end
function pushbutton2_Callback(hObject, eventdata, handles)
for k = 1:1000
disp(clock); % <-- This is the pseudo code
pause(0.5); % <-- Insert your real computations instead
% If button1 was pressed, stay in this loop:
while handles.Pause % [EDITED] WHILE instead of IF ?!
handles = guidata(hObject);
pause(0.2);
end
end
end

I do not understand, what you are asking for. I've marked the dummy lines now, which I have inserted instead of the real computations.
The while loop in Jan's answer 'pauses' execution if the pause-flag is set to true. This flag is set by pressing pushbutton1 which must be a togglebutton that has a binary state (on/off) (see the pushbutton1_Callback function in Jan's answer).
Note that execution isn't really paused. It's just stuck in the while loop until it gets the signal to escape.
>The GUIDE environment will be removed in a future release. After GUIDE is removed, existing GUIDE apps will continue to run in MATLAB® but they will not be editable in GUIDE - noted in r2021 documentation.
Other ways to implement pauses in Apps/GUIs.
- waitfor - example using AppDesigner but can be implemented outside of AppDesigner, too.
- uiprogressdlg with the Indeterminate option (requires uifigure which excludes GUIDE GUIs)
