Keyboard interaction using GUI and callback error

2 views (last 30 days)
Hallo! I've a GUI that upload images, make operation on that and than I show the result on a separate figure. Once the figure is showed I want to select some highlited objects using push buttons. This is the code of a button.
function specie1_Callback(hObject, eventdata, handles)
global stats L B path data count resolution Nimg;
figure(1);
[data count c] = riconosci(stats,L,B,resolution,1,data,count,Nimg);
set (handles.sp1number, 'String', c );
set (handles.total, 'String', num2str(size(data,1)-1));
When i use these buttons all works great but to perform the selection faster I'd like to select buttons with keyboard input and I try this code
function figure1_WindowKeyPressFcn(hObject, eventdata, handles)
switch eventdata.Key
case '1'
specie1_Callback
case '2'
specie2_Callback
case '3'
specie3_Callback
end
But when I push the kay 1 for example( that activate the callback of button specie1) and than make the selection I have this error.
??? Input argument "handles" is undefined.

set (handles.sp1number, 'String', c );

I don't understand where is the error. Thanks a lot in advance.

have you tried this:
function figure1_WindowKeyPressFcn(hObject, eventdata, handles)
switch eventdata.Key
case '1'
specie1_Callback(hObject, eventdata, handles)
case '2'
specie2_Callback(hObject, eventdata, handles)
case '3'
specie3_Callback(hObject, eventdata, handles)
end
it seems that you are not calling the function with the proper amount of inputs.

I think you deleted your earlier question in which I had asked you to explain whether your GUI was different than your figure(1). Or perhaps it was closed and I cannot see it now. Either way, please show
fig1 = figure(1);
get(fig1, 'WindowKeyPressFcn')
Is it the same as
@(hObject,eventdata)interfaccia('specie1_KeyPressFcn',hObject,eventdata,guidata(hObject))
?
What is the figure number associated with your GUI? Are you specifically opening figure(1) as a new figure? GUIDE does not normally manage multiple figures.
