XOBSERVE with xdisplay and xguid not updating

[m-kim]

Hello all,

I'm trying to use a slider so I can skim through some images I have. However, it appears that if I use

xcpp::display(img,id, active);

in XOBSERVE the display is not updated. I'm happy to dump my unit test here, but I put it in github, as well as on mybinder.

Expected outcome: Move the slider, and xcpp::display will display an image. Move the slider past 50, and a different image will replace the previous image in the same position as before.
Actual outcome: The image never changes.

What am I doing wrong here?

Cheers,
Mark

Hi @m-kim ,

I also tried to get the live access of slider using XOBSERVE.
xw::slider<double> slider;
slider.display()
XOBSERVE(slider, value, [](const auto& s) { std::cout << "Observer: New Slider value: " << s.value << std::endl; });

The above sample code from xwidget docs is not showing any output. Not sure the way which I am using it is right or not.
Please help if you have found any solutions or alternatives.

Thanks,
