For figures created via the uifigure() function and for containers within a uifigure, the property AutoResizeChildren will be 'on' by default. This means that AutoResizeChildren will try to resize the content when the uifigure is resized, without the need to write a SizeChangedFcn callback or to use uigridlayout.
An important note about AutoResizeChildren: it will resize components even if the components are in normalized units, and treat them as if they were in pixels units.
In this case, AutoResizeChildren on the panel that contains the uitabgroup is not working well because the panel is positioned by a uigridlayout, but the content is absolutely positioned. It is not recommended to mix absolute positioning and use of uigridlayout.
Here is my recommendation:
- If you would like to leverage normalized units, turn off AutoResizeChildren on all containers within the uifigure using the following right after the uifigure call:
set(IdD.Container, 'DefaultUipanelAutoresizechildren', 'off');
set(IdD.Container, 'DefaultUitabAutoresizechildren', 'off');
- Alternatively, use uigridlayout throughout the app. In other words, insert a uigridlayout between containers and their content, e.g. between the uipanel and the uitabgroup, and between the uitab and the axes.
