在uicontrols之间传递值

Question

我只是MATLAB GUI的初学者，只想知道简单的方法。

我有四个小部件：2个列表uicontrol，1个按钮uicontrol和1个静态文本uicontrol。

 function pushbutton1_Callback(hObject, eventdata, handles)
 x =get(handles.popupmenu1, 'Value')  % getting the value from the popupmenu
 % doing something with it
 y=get(handles.popupmenu2, 'Value')  %  getting the value and processing it 
 % doing something with it

 total=x+y
 set(handles.text1, 'String', num2str(total))  % set to total...but
 % I really want it to be a string with a total.  like 'Your total is %s', total

你能帮我设置文字字符串吗？

Answer 1

应该这样做：

str = sprintf('your total is %s', num2str(total)); % assuming total is a number, not a string
set(handles.statictext1, 'String', str); % replace handles.statictext1 by whatever the handle your static text box is
