iptremovecallback

Delete function handle from callback list

Syntax

iptremovecallback(obj,callback,ID)

Description

iptremovecallback(obj,callback,ID)deletes the callback with identifierIDfrom the list of callbacks for graphics objectobj.

Examples

Add and Remove Callbacks from Figure

Add three callbacks to a figure and try them interactively. Whenever MATLAB^®detects mouse motion over the figure, functionsf1,f2, andf3are called in that order.

h = figure; f1 = @(varargin) disp('Callback 1'); f2 = @(varargin) disp('Callback 2'); f3 = @(varargin) disp('Callback 3'); id1 = iptaddcallback(h,'WindowButtonMotionFcn', f1); id2 = iptaddcallback(h,'WindowButtonMotionFcn', f2); id3 = iptaddcallback(h,'WindowButtonMotionFcn', f3);

Remove the callbackf2. Move the mouse over the figure again. Whenever MATLAB detects mouse motion over the figure, only functionsf1andf3are called.

iptremovecallback(h,'WindowButtonMotionFcn',id2);
