Capturing Mouse click on a Figure
显示 更早的评论
Hi to All,
I am building a simple code that should detect the left mouse button when it is clicked on a figure. When the click is captured, a variable (e.g: y) should change its value from 0 to 1.
Th is is my code, in which I check on WindowButtonDown to invoke sendout function. sendout function shall set UserData to 1, in which I pass it to y. I run the code and I got ans = []!
Does anyone have an idea about mouse clicking in Matlab?!
Many thanks. Mahmood %% The code function y=main2
f=figure;
set(f,'WindowButtonDown',{@sendout});
function sendout(varargin)
set(f,'UserData',1);
end
y =get(f,'UserData');
end

k=waitforbuttonpress; % detect mouse click
if k==0 % on detect make y=1
