Problem in CurrentFigure or in gcf
显示 更早的评论
Hi,
this is my code after pressing pushbutton:
h=findobj(0,'Type','figure','Tag','figure1');
UserData=get(h,'UserData');
h=figure;
set(gcf, 'units','normalized','outerposition',[0 0 1 1],'name','a','numbertitle','off'); % Maximize figure.
g=plot(t,x);
UserData.d=7;
set(h,'UserData',UserData);
guidata(hObject, handles);
Why I do not have UserData.d=7 in others pushbuttons? Thank you

Use getappdata() and setappdata() as shown in the FAQ: http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.28s.29.3F

Because UserData is not defined for other callback functions. That is why you cannot access UserData with other pushbuttons. You can define it global and that will allow this being accessed by other callbacks.
