How do I get a cursor location in a pcshow figure?

Here is what I'm trying to do:

pcshow(PC);
set(gcf, 'WindowButtonDownFcn', {@getclicklocation, PC});

However, I end up with the error "Warning: Setting the "WindowButtonDownFcn" property is not permitted while this mode is active."

Does the pcshow function not allow for interaction?

The reason for this warning is that, by default, the pcshow plot turns the 'Rotate3D' setting on (so that you can view the point cloud easily). You can turn this setting off, and you will no longer receive that warning. Your new code could look like this:

pcshow(PC);
rotate3d off;
set(gcf, 'WindowButtonDownFcn', {@getclicklocation, PC});

Fantastic! Thank you!

Do you know how to apply this to a gui? I have tried:

% Attempt1
rotate3d off;
% Attempt2
rotate3d(gcf, 'off');
% Attempt3
rotate3d(handles.figure1, 'off');
% Attempt4
rotate3d(handles.axis1, 'off');

ah that was my mistake when writing it out I was testing without the space before the (
