How to work with the current point feature in app designer?

15 views (last 30 days)
Hello,
The below code is working in Matlab but I am unable to execute this same thing in Matlab app designer.
fig = figure('Interruptible', 'off');
ax1 = subplot(1,2,1);
ax2 = subplot(1,2,2);
fig.WindowButtonMotionFcn = @(~,~) [];
t = timer('Period', 0.1, 'ExecutionMode', 'fixedRate', 'TimerFcn', {@mouseMotionCB, ax1, ax2});
start(t)
ginput(1)
stop(t);
delete(t);
function mouseMotionCB(fig, event, ax1, ax2)
currentPoint1 = ax1.CurrentPoint(1,1:3);
x1 = currentPoint1(1);
y1 = currentPoint1(2);
if (ax1.XLim(1)<x1)&&(x1<ax1.XLim(2)) && (ax1.YLim(1)<y1)&&(y1<ax1.YLim(2))
fprintf('This is axes 1, Current Point is %f %f %f\n', currentPoint1);
end
currentPoint2 = ax2.CurrentPoint(1,1:3);
x2 = currentPoint2(1);
y2 = currentPoint2(2);
if (ax2.XLim(1)<x2)&&(x2<ax2.XLim(2)) && (ax2.YLim(1)<y2)&&(y2<ax2.YLim(2))
fprintf('This is axes 2, Current Point is %f %f %f\n', currentPoint2);
end
end
I have created an 'app1.mlapp', but this code is not executing in app designer .Can anyone help me with this?

Please see the app attached with the script for the callback function. Let me know if this addresses your problem.
Note, I also attached an app for the pop up window if you were interested in using this instead.

I changed
brush(app.UIAxes,"on")
to
brush(app.UIAxes,'on')
and it worked for me in R2021b (see attached).
Is there a reason crossair.mlapp doesn't work for you?
