设置工具栏出问题?

X1=imread('打开.bmp');
X2=imread('保存.bmp');
X3=imread('打印.bmp');
X4=imread('放大.bmp');
X5=imread('undo.bmp');
X6=imread('redo.bmp');
% 建立工具栏
uipushtool('Separator','on','TooltipString','打开','ClickedCallback',...
@open_Callback,'CData',X1);
uipushtool('Separator','on','TooltipString','保存','ClickedCallback',...
@save_Callback,'CData',X2);
uipushtool('Separator','on','TooltipString','打印','ClickedCallback',...
'printdlg','CData',X3);
uipushtool('Separator','on','TooltipString','放大','ClickedCallback',...
@image_zoom_Callback,'CData',X4);
uipushtool('Separator','on','TooltipString','撤消','ClickedCallback',...
@remove_Callback,'CData',X5);
uipushtool('Separator','on','TooltipString','恢复','ClickedCallback',...
@resume_Callback,'CData',X6);

创建工具栏成功,但是只有open能正常使用,其它的都提示

?? Input argument "handles" is undefined.

??? Error while evaluating uipushtool ClickedCallback.

这是为什么,请指教,open_Callback里也用到handles!

open_Callback回调函数里应该是没有用到handles变量,只是函数定义里有handles输入参数吧,
如果不是的话最好多贴点代码上来


OldHandle = findobj( \'Name\', \'悲伤\' ) ;if ~isempty(OldHandle),delete(OldHandle) ;end for Time = \'现在\':\'每一天\':\'永远\',set( gco, \'心情\', \'快乐\');end % 这段代码为你天天快乐而存在

function varargout = Myprogram1(varargin)
% MYPROGRAM1 M-file for Myprogram1.fig
% MYPROGRAM1, by itself, creates a new MYPROGRAM1 or raises the existing
% singleton*.
%
% H = MYPROGRAM1 returns the handle to a new MYPROGRAM1 or the handle to
% the existing singleton*.
%
% MYPROGRAM1('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in MYPROGRAM1.M with the given input arguments.
%
% MYPROGRAM1('Property','Value',...) creates a new MYPROGRAM1 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before Myprogram1_OpeningFunction gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to Myprogram1_OpeningFcn via varargin.

% instance to run (singleton)".

handles你根本没传,当然会出错,open回调函数里没出错是因为它里面没用到handles里的值,只有给handles里的域赋值,所以不会出问题,比如
function save_Callback(hObject, eventdata, handles)你想正常使用,需要再回调函数的第一行加上这样一句
handles = guidata(hObject);就可以了


OldHandle = findobj( \'Name\', \'悲伤\' ) ;if ~isempty(OldHandle),delete(OldHandle) ;end for Time = \'现在\':\'每一天\':\'永远\',set( gco, \'心情\', \'快乐\');end % 这段代码为你天天快乐而存在

终于好了,我最近折腾来折腾去,还是一塌糊涂啊。实在太感谢了!
