I want to find the position of mouse in anywhere of screen in GUI.
C = get(0,'PointerLocation'); I knew that this code can find any position on screen and then I use it with GUI but it didn't work.
this following is my code.
function mouse()
f=figure; set (f, 'WindowButtonDownFcn', @mouseMove); % by click
function mouseMove (hObject,~)
C = get(0,'PointerLocation'); title(['(X,Y) = (', num2str(C(1,1)), ', ',num2str(C(1,2)), ')']);

Firstly You need to add end statements to each function. See the following documentation on local functions.
function [out1] = name(in1)
% some code
in2 = in1;
[out2] = subFunction(in2);
out1 = out2;
end
function [out2] = subFunction(in2)
% some other code
end
Next you are setting the property to the handle of the figure - this means your callback to mouseMove will only execute whilst your cursor is over the figure. To do what you are asking you would need to set the function for the root object.
However i'm not sure if this is possible based on the documentation - Root Object Properties.
