Unable to perform assignment because dot indexing is not supported for variables of this type.

Hello everyone,

Ik downloaded a script form Wang Gang called; move a 3D object with mouse in a traditional 4-view window. The code doesn't work. This script was last updated in 2010 than. Since then the mathlab software got upedates. I think this is te reason why the code doesn't work anymore. I think the problem is in the strucutre, but it seems I can't figure it out.

The error is:

Unable to perform assignment because dot indexing is not supported for
variables of this type.

Error in TDFig>startmovit (line 188)
gui.currenthandle = src;
Error while evaluating Patch ButtonDownFcn.

line 187 and futher looks like this:

% Set callbacks 
gui.currenthandle = src;
thisfig = gcbf();
set(thisfig,'WindowButtonMotionFcn',@movit);
set(thisfig,'WindowButtonUpFcn',@stopmovit);
gui.startpoint = get(gca,'CurrentPoint'); 

They use ButtonDownFcn in the following context:

function move3dObject(h)   
gui = get(gcf,'UserData');
set(h,'ButtonDownFcn',@startmovit);
set(gcf,'UserData',gui);

does somebody know how to fix this error?
