Is there any way to change mouse cursor on hover to object (to axes for example) in GUI? If I want to change cursor on hover to figure, i should write: set(gcf,'Pointer','hand'); But axes or button don't have such parameter.

Previously grateful for attention.

See

iptSetPointerBehavior(obj,pointerBehavior)

along with

iptPointerManager(hFigure,'enable')

which can be used to automatically change the pointer symbol when it hovers over certain objects within the GUI. In regular figures, the pointer manager is supported with figure | axes | uipanel | image objects. As of r2020a, the pointer manager can also be used with uifigures but it seems that only uifigure and uiaxes are supported plus any object plotted within the axes.

Work at the figure level, and have the figure mouse movement callback figure out what is "under" the cursor and change the cursor appropriately. (I would suggest that the callback should not just look at the "top" graphics object, and should instead look at the top "hittable" graphics object.)
