Problems with UIFigureKeyPress and push buttons in App Designer

Hi there! I noticed a very annoying thing

I am doing a calculator with abillity to enter operations and digits

When I click on any object (e.x. push button,text area), its borders get blue and then I am not able to use my keyboard. I need to click on free space in order to fix it.

Here is the example.

How can I deal with it?

The issue you are experiencing is common in GUI applications, where the focus is shifted to a specific UI element after interaction, preventing keyboard input from being directed elsewhere. Here are two ways to address this issue:

1. Focus Management: Set Focus Back to Main Window: After a button click or any UI interaction, programmatically set the focus back to the main window or a specific element that should capture keyboard input.

% Assuming 'mainFigure' is your main GUI figure handle
uicontrol(mainFigure);

2. Event Listeners: Add event listeners to detect when a UI element is clicked and automatically redirect focus back to the desired element.

% Callback function for a button
function buttonCallback(~, ~)
    % Your button logic here
    uicontrol(mainFigure); % Redirect focus
end

I hope this helps!
