matlab axes(handles.axes1)

handle 可以用作动词或者名词。动词：1.用手感觉或运行 2.管理，处理或负责(情形或问题)例：1. Large objects can be hard to handle. 2. He can handle this situation.名词：物品的把手例：The handle of the pan was hot.

control:控制，主动地。handle：处理，被动地，接受收到再去处理。

不能单独用的，应该是用在一个短语里

是句柄类型吧？

进处口贸易有限公司

shots投射，投篮。dunks灌篮，扣篮。biocks盖帽。steals抢断。handles控球。rebounds篮板球。

句柄

SHOTS 投篮。DUNKS 灌篮。BLOCKS 盖帽 STEALS 抢断。HANDLES 控球。REBOUNDS 篮板。

上述代码中，以Private形式声明了标识名为“Picturebox1_Double”的Picturebox1、Picturebox2、Picturebox3、Picturebox4的鼠标双击事件。（也就是说，双击任何一个Picturebox都会引发这个“Picturebox1_Double”的事件）Private Sub 是声明事件开始的标记[更改事件的可见性，告诉编译器其他窗体能不能调用此事件，如果可以，那么这个Private Sub应改为Public Sub]，此事件的标识名紧跟其后，方法函数被包括在圆括号里，Handle才是指示控件的事件比如，我要声明Button1的点击事件：Private Sub AAAAAAA(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click那么，这个是Button1的Click事件，其标识名为“AAAAAAA”

handles 是Figure中所有组件句柄的结构体,比如handles.edit就是GUI界面中的Edit控件句柄

varargout 实际返回的参量，变长度输入宗量 ，object目标，对象的意思， hObject 是指向同步对象句柄的指针， handles是操纵掌控的意思，eventdata意思是事件数据 事件资料。传回伺服器或资资料库事件的相关资讯。

varargout 实际返回的参量，变长度输入宗量 ，object目标，对象的意思， hObject 是指向同步对象句柄的指针， handles是操纵掌控的意思，eventdata意思是事件数据 事件资料。传回伺服器或资资料库事件的相关资讯。

就是说括号里那个函数未定义，或者说变量不存在。我觉得是不是函数调用的问题，你看看有没有handles那个函数，或者那个函数不在目录下。试试看

你要定义handles，不然MATLAB不认识这个东西A要从handles对象的a_edit里提取字符串

对于批量的对象就用循环好了，一个一个复制粘贴并不是很好的解决方案。首先写好事件处理函数。Private Sub TextBoxChanged(sender As Object, e As EventArgs)"一些代码End Sub下面是主函数Dim tests() As TextBox "数组或集合字段名称用复数Dim num As Integer = 80 "控件总个数ReDim tests(num)For i = 0 To tests.Count - 1Dim item As New TextBoxtest(i) = itemAddHandler item.TextChanged, AddressOf TextBoxChanged "绑定对象事件到处理函数Next手机写的可能难免有错，理解就行

这个执行顺序由.net内部处理和维护现在我测试了下，如果动态添加delegate的话，那么事件调用就会按照添加的先后顺序来执行不过在过程里直接用"handles 某个事件"来指定的话，顺序就不一定了，比如我测试你的代码就是3，1，2的循序，和处理过程的名字应该没什么关系不过事件的处理过程会按照在invocation list里的循序来执行给你一段代码 Function GetHandlers(ByVal instance As Object, ByVal e As String) As String Dim pi As PropertyInfo = GetType(Button).GetProperty("Events", BindingFlags.Instance Or BindingFlags.NonPublic) Dim ehl As EventHandlerList = CType(pi.GetValue(instance, Nothing), EventHandlerList) Dim fi As FieldInfo = GetType(Control).GetField("Event" & e, BindingFlags.Static Or BindingFlags.NonPublic) Dim d As [Delegate] = ehl(fi.GetValue(Nothing)) Dim handlerStr As String = Nothing If (d <> Nothing) Then For Each i As [Delegate] In d.GetInvocationList() handlerStr = handlerStr & i.Method.Name & vbCrLf Next Else handlerStr = "无" End If Return handlerStr End Function调用gethandlers函数可以得到某个控件的某个事件注册的所有handler，这个顺序就是真正的调用顺序了但我觉得还是应该不要太过依赖这部分内容，不管是用handles还是addhandler，现在是这样，以后的版本说不定就变成其他了，因为ms并没有对他们有过任何的明文说明

两个语法其实指的是同一个意思V = get(H,"PropertyName") returns the value of the specified property for the graphics object with handle H.H是图形句柄，即为某个窗口对象分配的数字，而利用这个数字可以控制窗口内对象的属性，如果还有疑问，请Hi我啊

handles.inputtype=2;光看这条看出来什么含义，这是自己定义的一个结构变量，应该在其他地方还用到这个结构体中的成员函数，这里用了handles.XXX来传递数据，相当于全局变量，然后用到guidata来更新数据。你看看其他的地方用到handles.inputtype

这是以前的一个帖子。http://www.ilovematlab.cn/thread-47-1-1.html可以稍微看看。

我运行了你给的代码，是运行成功的。这段代码应该没有问题的。

这个问题我刚遇到了，一搜索发现你也在问，我说一下我怎么解决的这个应该是你引用了不存在的对象，后来我发现我的button1的nane属性是被我改过了，所以运行的时候自然找不到对象了，其实VS会用下划线的方式提醒你错误地点，由于在错误语句需要拉动滑条才能看到，我没注意，你检查一下，看看它提示你哪里出错了（有蓝色的下划线）

你的代码前面应该有clear

静态文本框？是text吧

If sender.checked = True Then Select Case sender.name Case "Rad加" Lbl运算符.Text = "+" Case "Rad减" Lbl运算符.Text = "-" Case "Rad乘" Lbl运算符.Text = "X" Case "Rad除" Lbl运算符.Text = "÷" End Select txt结果.Focus()end if

找本matlab的书，GUI的，一般都会介绍。照上面写，肯定没问题。

代码框架是自动生成的吧，你确定没有不小心改错了？请把报错信息、以及根据报错信息找到出错的那个回调函数代码贴出来，以便进一步分析。

hObject是当前控件的句柄，handles包含了整个程序所有的句柄。在当前控件的callback里可以用hObject，也可用handles.***；在别的控件的callback里可以用handles.***来调用别的控件的句柄

就是说括号里那个函数未定义，或者说变量不存在。我觉得是不是函数调用的问题，你看看有没有handles那个函数，或者那个函数不在目录下。试试看

f=imadjust(handles,img,[],[],p1)这句话里的 handles,img中间应该是点而不是逗号望采纳

get里面应该是handles.edit1，是点不是逗号。

关于gui中的 hobject eventdata handles都是滚刀和事件数据处理的意思

image是图片的意思，带有“_image”的一般都是图片文件。你所问的handles.figure_image应该是“管理图标”的意思。希望有所帮助。

可以使用这个代码：[filename pathname]=uiputfile({"*.jpg","jpg file(*.jpg)");str = [pathname filename];strBefore = str(1:end-4);strEx = str(end-3 : end);figure("visible", "off");strcmp(strEx, ".jpg")fullName = [strBefore,".jpg"];h=get(handles.axes1,"children");figure("visible","off");axes;copyobj(h,gca)print(gcf,"-dmeta",fullName)

把函数中修改过的东西进行更新保存

这个是方便在调用GUI程序的时候返回一个值，默认是返回当前GUI的句柄，也就是hObject

看你的代码，你是动态绑定按钮事件？如果是的话，请这样更改——Public Class Form1 Dim WithEvents btnSubmit As Button "动态Button Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load End Sub Public Sub New() InitializeComponent() End Sub Private Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click End SubEnd Class

你用imshow显示图像的时候可以h = imshow（。。。）,把h保存在handles里handles.h = h;guidata(hObject,handles);要用的时候h = handles.h;图像数据为img = h.CData;img处理后，只要用set(handles.h,"CData",img)；重新显示即可。

的HookProc根据鼠标坐标的记录这样的结构，一个消息的形式返回到主程序。的困难的？ pMouse：TPoint; 开始 ... pMouse：= MouseHook.pt; SendMessage函数（Application.MainForm.Handle的WM_XXXX整数（_AT_ pMouse的），0）; ... 然后在你的主程序收到该消息。 。 。

你究竟使用handles.Mode还是handles.optMode来表示状态？case 情况里面的代码，只有plot所用的符号不同所以没有必要重复那么多代码吧其他代码都可以写在swith case语句之外只用在不同case值中写相应的plot语句就可以了

你在第一个函数读入I1后，应该把I1保存在handles里，如handles.I1 = I1;并且保存一下guidata(hObject,handles);第二个函数要用handles.I1代替I1.你好像准备用全局变量，虽然可以，但不推荐。如果必须用，那么应该在要用该数据的函数里声明。所以在两个函数里都需要先gloabal I1;

因为a，b不是全局变量,所以把以下两句从edit控件的响应中剪切a=num2double(get(handles.edit1,"string"));b=num2double(get(handles.edit2,"string"));粘贴到pushbutton的响应里即function pushbutton1_Callback(hObject, eventdata, handles)a=num2double(get(handles.edit1,"string"));b=num2double(get(handles.edit2,"string"));plot(a,b,"r*")
