I have a counter that increment each time i click on a pushbutton and the value is stored in a guidata which works it gives me the wanted value. (The function that increments is in the same file as the gui)
But i want to get the value form the guidata in another file as a condifition for a if but i always return me this error :
Undefined variable "handles" or class "handles.X".
Error in kgexec4n (line 67)
if get(guidata(hf,handles.X),'Value')==1
Error while evaluating uicontrol Callback
and here is the gui code with the function and the pushbutton
function h0=kgui4n
%KGUI4N construction de la boite de dialogue pour KGEXEC4N

blanc=[1 1 1];
gris=blanc*0.75;
%figure
h0=figure(...
'Units','characters',...
'DefaultUicontrolUnits','characters',...
'Color',gris,...
'DefaultUicontrolBackgroundColor',gris,...
'HandleVisibility','callback',...
'IntegerHandle','off',...
'MenuBar','none',...

'NumberTitle','off',...
'Position',[100 30 110 25],...
'Resize','on',...
'Tag','NormeDlg',...
'WindowStyle','modal',...
'ToolBar','none');
%% Pushbutton
handles.X = 0;
handles.button = uicontrol(h0,...
'Callback',@buttonCB,...
'Position',[10 0.5 9 2],...
'String','count',...
'Tag','count');
guidata(h0, handles);
%%%%%%%%%%%%%
function buttonCB(ButtonH, EventData)
handles = guidata(ButtonH);
handles.X = handles.X + 1;
if handles.X > 3
handles.X = 0
end
guidata(ButtonH, handles)
I would like to know how i could get the value of handles.X which is stored in the guidata and use it in another file ?

handles_hf = guidata(hf);
if handles_hf.X.Value == 1

You need some way of getting the handle of the figure created by kgui4n . For example you might do
hf = findobj(groot, 'type', 'figure', 'tag', 'NormeDlg');
handles_hf = guidata(hf);
if handles_hf.X == 1
etc
end
