Apps you create in App Designer are resizable by default. The components reposition
and resize automatically as the user changes the size of the window at run-time. The
AutoResizeChildren property controls this automatic resize
behavior. By default, App Designer enables this property for the UI figure and all its
child containers such as panels and tabs. To set the
AutoResizeChildren property of a child container to a different
value, set the value for the child container after setting the value for the parent.
AutoResizeChildren property is enabled for a container,
MATLAB® manages the size and position of only the immediate children in the
container. Components in nested containers are managed by the
AutoResizeChildren property of their immediate parent. To
ensure that the alignment of components relative to one another (like a grouping of
buttons) is preserved when your app is resized, parent the grouping of components to a
panel, instead of directly to the figure.
When graphics objects, like axes or charts, use normalized position units and are
the child of a resizeable container, certain properties of the graphics object are
affected after the parent container is resized. For example, if axes or charts use a
'normalized' for the
and are parented to a container with the
property set to
The value of the
OuterPosition property for the
axes or chart changes when the app is resized.
The axes or chart does not shrink smaller than a minimum size when the app is resized.
If you want to avoid either of these behaviors, set the
AutoResizeChildren property of the container to
If you want more flexibility over how your app automatically resizes, use grid
layout managers or the auto-reflow options in App Designer instead of the
AutoResizeChildren property. For more information about
these options, see:
If the resize behaviors supported by
layout managers, or auto-reflow options are not the behaviors you want, then you can
create custom resize behaviors by writing a
callback function for the container. For more information, see the SizeChangedFcn property.
