Examples

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);
