Hi Pietro,
I understand that you are facing trouble keeping the figure in the centre of your app when resizing it.
You can achieve the following using the steps below:
- Define a “UIFigureSizeChanged” callback function in the following manner:
% Size changed function: UIFigure
function UIFigureSizeChanged(app, event)
if app.UIFigure.WindowState == "maximized"
app.Panel.Position = [0 0 app.UIFigure.Position(3) app.UIFigure.Position(4)];
position = get(groot, 'Screensize');
app.Image.Position = [(position(3) - app.Image.Position(3)) / 2, (position(4) - app.Image.Position(4)) / 2, app.Image.Position(3), app.Image.Position(4)];
elseif app.UIFigure.WindowState == "normal"
app.Panel.Position = [0 0 app.UIFigure.Position(3) app.UIFigure.Position(4)];
app.Image.Position = [(app.Panel.Position(3) - app.Image.Position(3)) / 2, (app.Panel.Position(4) - app.Image.Position(4)) / 2, app.Image.Position(3), app.Image.Position(4)];
end
end
- In the code above, I have used a panel and placed an image in the centre of the panel. In both the “maximized” and “normal” state of the app, the panel position and size are updated to fit the entire UI Figure area.
- When the UI Figure will be in the “maximized” state, the size of the desktop screen is stored in the “position” variable and using this, the image placed in the panel is pushed to the centre of the screen with the dimensions intact.
- When the UI Figure is in the “normal” state, the image will be pushed to the centre of the panel using the position of the panel keeping the dimension intact.
- One thing to keep in mind here is that the “UIFigureSizeChanged” callback function only works when the “AutoResizeChildren” property is not selected, so make sure to uncheck the box.
I hope this helps!

Nivedita.
