I noticed that design and layout of a figure can be compromised when the figure's size or dimension is changed.

In most cases, use of 'Units' = 'normalized' can work, but not always.

For example, UI control buttons and sliders can be squashed by 'Units' = 'normalized'. To keep the size of uicontrol objects practical, you would have to change the 'Units' to 'px' and fix the size of buttons and sliders and then set them back to 'normalized'.

I wonder if this is possible with a callback function for figure object. Can a figure object detect its own change in size and invoke a callback function?

The 'SizeChangedFcn' property of the figure can be used for this.

Superb! It worked magically. I spent a good time searching this for figure property documentation but could not find it. Thanks a lot for the prompt answer!
