Hi,
I understand that you want to insert text next to the existing text when a button is clicked.
This can be done by appending new text to the existing text as below.
I created a textbox and button as shown below.
Whenever the 'Button' is clicked, the current time is appened next to the existing text in the textbox.
Please check callback function associated with Button click below. This function appends next text whenever 'Button' is clicked.
% Button pushed function: Button
function ButtonPushed(app, event)
% Get the current time as a string
currentTime = char(datetime('now', 'Format', 'HH:mm:ss'));
% Check if the TextArea is empty
if isempty(app.TextArea.Value)
% If empty, add the current time without a comma
newContent = currentTime;
else
% If not empty, append the current time with a comma and space
newContent = [char(app.TextArea.Value), ', ', currentTime];
end
% Update the TextArea with the new content
app.TextArea.Value = newContent;
end
Similarly, one more use case is below. Whenever, the button is clicked a new number is appended to the text box, which counts the number of times the button was clicked. And this time, there is no space or comma between these numbers.
Please check the screenshot of the App below.
Add a property called ButtonClickCount as below.
properties (Access = public)
ButtonClickCount double = 0; % New property to track button clicks
end
Please check callback function associated with Button click below. This function appends next text whenever 'Button' is clicked.
% Button pushed function: Button
function ButtonPushed(app, event)
% Increment the button click count
app.ButtonClickCount = app.ButtonClickCount + 1;
% Convert the count to string
countStr = num2str(app.ButtonClickCount);
% Append the count to the existing content of the TextArea
newContent = [char(app.TextArea.Value), countStr];
% Update the TextArea with the new content
app.TextArea.Value = newContent;
end
Hope this helps in resolving your query!
