iptremovecallback

Delete function handle from callback list

Syntax

iptremovecallback(obj,callback,ID)

Description

iptremovecallback(obj,callback,ID) deletes the callback with identifier ID from the list of callbacks for graphics object obj.

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, functions f1, f2, and f3 are 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 callback f2. Move the mouse over the figure again. Whenever MATLAB detects mouse motion over the figure, only functions f1 and f3 are called.

iptremovecallback(h,'WindowButtonMotionFcn',id2);

Input Arguments

obj — Graphics object

figure | axes | uipanel | image

Graphics object, specified as a handle to a figure, axes, uipanel, or image graphics objects.

callback — Callback property

character vector

Callback property of the graphics object obj, specified as a character vector. For a list of callbacks for graphics objects, see Figure Properties, Axes Properties, Panel Properties, and Image Properties.

Data Types: char

ID — Callback identifier

positive integer

Callback identifier for function fun, specified as a positive integer. This identifier is returned by iptaddcallback when you add a function to the callback list.
