Update image in axes (GUI) after imfreehand

Hi,
I have an open imfreehand pushbutton that shows the current image in an axes (within a GUI)
As I add some graphics using the imfreehand, how can I update the image in the axes after closing the imfreehand (after hitting the X, it does not have exit in the File menu)?
Code:
function freeHandButton_Callback(hObject, eventdata, handles)
% hObject handle to freeHandButton (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
I = getappdata(handles.imageAxes , 'yourVariable');
figure, imshow(I);
Thanks

I'm not sure what you mean by update. You can call drawnow if you want, or call plot() to plot the coordinates that you drew over the image.

If it blew them away, you will probably have to redraw them. Or maybe there's some way to protect them with the hittest property - I don't know. Maybe call tech support and ask.
