我想用Bushbutton(Bushbutton)制作一个主GUI。 当按pb1 =>用按钮(Upb1),编辑(Uet1)和文本(Ust1)打开图形(图)。 我想:当按Upb1时,Ust1显示Uet1的数量(同样,当改变Uet1并按Upb1,Ust1改变时)。
我编写此代码但不起作用(var1
未定义)。我该怎么办?
function Bushbutton_Callback(hObject, eventdata, handles) % main
Fig=figure('MenuBar','none');
Ust1= uicontrol(Fig,...
'Position',[50 60 80 20 ],...
'Style','text')
Uet1= uicontrol(Fig,...
'Position',[50 90 80 20 ],...
'Style','edit',...
'string',10,...
'callback',@printNum)
Upb1= uicontrol(Fig,...
'Position',[50 30 80 20 ],...
'Style','pushbutton',...
'callback',@printNum)
function printNum(hObject, eventdata,handles)
var1=get(Uet1,'string')
set(Ust,'string',var1)
答案 0 :(得分:1)
您需要更改第二个函数的范围,以便它可以访问变量Uet1和Ust1。这意味着,你需要在Bushbutton_Callback的范围内实现它(可能想称之为Pushbutton_Callback ......)
function Bushbutton_Callback(hObject, eventdata, handles)
Fig=figure('MenuBar','none');
Ust1= uicontrol(Fig,...
'Position',[50 60 80 20 ],...
'Style','text')
Uet1= uicontrol(Fig,...
'Position',[50 90 80 20 ],...
'Style','edit',...
'string',10,...
'callback',@printNum)
Upb1= uicontrol(Fig,...
'Position',[50 30 80 20 ],...
'Style','pushbutton',...
'callback',@printNum)
function printNum(hObject, eventdata,handles)
var1=get(Uet1,'string')
set(Ust1,'string',var1)
end
end
