To achieve continuous monitoring of the “GetAcquisitionProgress” function and automatically update the values without explicitly calling “islogging(obj)” I would reccomand using the MATLAB event listeners.
For a better understanding of creating event listeners and making calls, kindly refer to the following code snippet.
classdef CameraGUI < handle
properties
AcquisitionProgress
TimerObj
end
events
ProgressChanged
end
methods
function obj = CameraGUI()
% Initialize properties
obj.AcquisitionProgress = 0;
% Set up a listener for the ProgressChanged event
addlistener(obj, 'ProgressChanged', @(src, event) obj.updateProgress());
% Set up a timer to periodically check acquisition progress
obj.TimerObj = timer('ExecutionMode', 'fixedRate', ...
'Period', 1, ... % Check every second
'TimerFcn', @(~,~) obj.checkProgress());
start(obj.TimerObj);
end
function checkProgress(obj)
[ret, acc, series] = GetAcquisitionProgress();
CheckWarning(ret);
if series ~= obj.AcquisitionProgress
obj.AcquisitionProgress = series;
notify(obj, 'ProgressChanged'); % Trigger the event
end
end
function updateProgress(obj)
% Update the GUI or perform any action needed when progress changes
disp(['Acquisition Progress Updated: ', num2str(obj.AcquisitionProgress)]);
end
end
end
function [ret, acc, series] = GetAcquisitionProgress()
% Mock implementation of GetAcquisitionProgress
ret = 0;
acc = 0;
series = 0; % Random value to simulate progress
end
function CheckWarning(ret)
% Mock implementation of CheckWarning
if ret ~= 0
warning('An error occurred.');
end
end
