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});
