Hello everyone! I have custom analysing function that analyses the directory. I am calling this function from the main GUI app in AppDesigner. The function that I am calling from the main app has the following structure,
function analyse_result = analyse(path_dir)
objects = objects_in_dir(path_dir)
for ii = 1:length(objects)
do_something
end
end
Now I've added a label text on the gui and called ProgressLabel. What I want to do is to update this label inside the function body, so I've updated the function like so,
function analyse_result = analyse(path_dir,app.ProgressLabel.Text)
objects = objects_in_dir(path_dir)
for ii = 1:length(objects)
do_something
app.ProgressLabel.Text = sprintf("Iteration: %%u",(ii/length(objects))*100)
end
end
But when I'm calling this updated function from the main gui with added new variable, nothing changes on the text label. How can I solve this issuse?

Hello Arda,
function analyse_result = analyse(path_dir,app.ProgressLabel.Text)
objects = objects_in_dir(path_dir)
for ii = 1:length(objects)
do_something
app.ProgressLabel.Text = sprintf("Iteration: %%u",(ii/length(objects))*100)
drawnow
end
end
Same is necessary for other operations such as while loop terminations via a button.
