Hi,
I would like to pass an array of handles to uipushtool 'ClickedCallback'.
when I tried doing that I received the following error message:
??? Undefined function or variable 'handel'.
??? Error while evaluating uipushtool ClickedCallback
This is the code I wrote:
function [ ] = Creat_menu( fig ,im)
%Creat_menu adds push buttons to the import picture.
%The push buttons that are added reprisents the sport type.
%h = figure('ToolBar','none');
% Create the toolbar
th = uitoolbar(fig);
% Add a push tool to the toolbar
tennis = imread('tennis logo 16x16.jpg');%Read the image.
basketball = imread('basketball logo 16x16.jpg');%Read the image.
volleyball = imread('volleyball logo 16x16.jpg');%Read the image.
handel(1) = uicontrol('style','checkbox','units','pixels',...
'position',[0,0,80,15],'string','Color_Filter');
handel(2) = uicontrol('style','checkbox','units','pixels',...
'position',[0,20,100,15],'string','Variance_Filter');
handel(3) = uicontrol('style','checkbox','units','pixels',...
'position',[0,40,100,15],'string','User Algoritem');
handel(4) = uicontrol('style','checkbox','units','pixels',...
'position',[0,60,100,15],'string','Matlab Algoritem');
tennis_pth = uipushtool(th,'CData',tennis,...
'TooltipString','tennis',...
'HandleVisibility','off',...
'ClickedCallback','SearchForBall(im,handel,''Tennis'')'...
);
basketball_pth = uipushtool(th,'CData',basketball,...
'TooltipString','basketball',...
'HandleVisibility','off',...
'ClickedCallback','SearchForBall(im,handel,''Basketball'')'...
);
volleyball_pth = uipushtool(th,'CData',volleyball,...
'TooltipString','volleyball',...
'HandleVisibility','off',...
'ClickedCallback','SearchForBall(im,handel,''Volleyball'')'...
);
end
Thanks,
Michael

You are defining handel within Creat_menu. The handel that appears when you create those callbacks is in string form. Strings for callbacks are evaluated in the context of the base workspace... and in that workspace, handel does not exist.
Define your callbacks as anonymous functions instead, such as
'ClickedCallback', @(im) SearchForBall(im, handel, 'Tennis')

Do not quote the anonymous function. Not your
@(im)'SearchForBall(im,handel,''Basketball'')'
but just
@(im)SearchForBall(im,handel,'Basketball')
