The figure number is the integer number that acts as a handle for the figure. gcf() But Steve's solution of using guidata(src) is much better. > Also, if I pass down the figure number, then define handles in the > callback, does that mean that I don't have to pass handles to the > function? i.e.: > set(handles.currimage,'ButtonDownFcn',@(src,eventdata)axes1_ButtonDownFcn(src,eventdata)); Why bother? Why not just use set(handles.currimage, 'ButtonDownFcn', {@axes1_ButtonDownFcn}) Your anonymous function already assumes that it will be passed two parameters, and those are the same two parameters that need to be passed to axes1_ButtonDownFcn and the same order, so using the anonymous function just adds overhead and complexity and opportunity for mistakes.

I'm now getting exactly what I was looking for. Every time I click, the set of coordinates is appended to handles.coords. Now I can move on to other issues. Big thanks to Steve, us, and especially Walter for the help. |
