全文转载自【无名小卒1990】的博客【matlab GUI之常用对话框（三）】

常用的对话框（三）

1.普通对话框  dialog

h=dialog(‘PropertyName’,’PropertyValue’……)

[cpp] view plain copy

print ?

1. %普通对话框  
2. h=dialog(’name’,‘关于…’,‘position’,[200 200 200 70]);  
3.   
4. uicontrol(’parent’,h,‘style’,‘text’,‘string’,‘你好！’,‘position’,[50 40 120 20],‘fontsize’,12);  
5. uicontrol(’parent’,h,‘style’,‘pushbutton’,‘position’,…  
6.    [80 10 50 20],’string’,‘确定’,‘callback’,‘delete(gcbf)’);  

2.错误对话框 errordlg

调用格式：

h = errordlg
h = errordlg(errorstring)
h = errordlg(errorstring,dlgname)
h = errordlg(errorstring,dlgname,createmode)

errordlg函数–>2 axes对象和1 pushbutton对象–>axes子对象有image对象和text对象

[cpp] view plain copy

print ?

1. %错误对话框  
2. h=errordlg(’警告’,‘错误’);  
3. ha=get(h,’children’);  
4.   
5. hu=findall(allchild(h),’style’,‘pushbutton’);  
6. set(hu,’string’,‘确定’);  
7. ht=findall(ha,’type’,‘text’);  
8. set(ht,’fontsize’,20,‘fontname’,‘隶书’);  

3.警告对话框  warndlg

h = warndlg
h = warndlg(warningstring)
h = warndlg(warningstring,dlgname)
h = warndlg(warningstring,dlgname,createmode)

[cpp] view plain copy

print ?

1. %警告对话框  
2. h=warndlg(’内存不足’,‘警告’,‘modal’);  

4.帮助对话框 warndlg

helpdlg
helpdlg(‘helpstring’)
helpdlg(‘helpstring’,’dlgname’)
h = helpdlg(…)

[cpp] view plain copy

print ?

1. %帮助对话框  
2. helpdlg(’双击对象进入编辑状态’,‘提示’);  

5.信息对话框 msgbox

h = msgbox(Message)
h = msgbox(Message,Title)
h = msgbox(Message,Title,Icon)
h = msgbox(Message,Title,’custom’,IconData,IconCMap)
h = msgbox(…,CreateMode) 

Icon中有‘error’、‘warn’、‘help’、‘custom’

CreateMode中有 modal   non-modal（Default） replace

[cpp] view plain copy

print ?

1. %信息对话框  
2. msgbox(’中日钓鱼岛之争愈演愈烈！’,‘每日新闻’,‘warn’);  

6.提问对话框 questdlg

button = questdlg(‘qstring’)
button = questdlg(‘qstring’,’title’)
button = questdlg(‘qstring’,’title’,default)
button = questdlg(‘qstring’,’title’,’str1’,’str2’,default) %两个按钮
button = questdlg(‘qstring’,’title’,’str1’,’str2’,’str3’,default) %三个按钮
button = questdlg(‘qstring’,’title’, …, options)

[cpp] view plain copy

print ?

1. %提问对话框  
2. questdlg(’今天你学习了吗？’,‘问题提示’,‘Yes’,‘No’,‘Yes’);
