I'm having a problem with handles inside my WindowButtonDownFcn function. I have no idea why it won't work. I've been trying to set global variables and handles in my WindowButtonDownFcn, but nothing works.

I'm new to this website, I hope this helps.

Thanks!


% --------------------------------------------------------------------
function Start_Selection_Callback(hObject, eventdata, handles)
% hObject handle to Start_Selection (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
set(gcf,'Pointer','fullcrosshair');
set(gcf,'WindowButtonDownFcn',@button_down1);

function button_down1(hObject, eventdata, handles)
[pointspicked] = select3d
% select3d returns coordinates
set(handles.C1,'String',num2str(pointspicked(1)));
assignin('base','pointspicked',pointspicked);
