在uicontrols之間傳遞值

Question

我只是MATLAB GUI的初學者，只想知道執行此操作的簡單方法。

我有四個小部件：2個列表uicontrol ，1個按鈕uicontrol以及1個靜態文本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

您能幫我設置文本字符串嗎？

Answer 1

這樣的事情應該做：

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
