Turning HitTest off for imrect

I have been trying to turn the HitTest property off for an imrect object, such that I can click on objects behind it. However, a simple "set(imrectHan,'HitTest','off');" does not do the trick. Does anyone know how to solve this?

The imrect is built from low-level lines and patches so turn the imrect's Children's 'HitTest' off.

h = imrect
set(get(h,'Children'),'HitTest','off')

That's good to know Sean thanks!

Thank you, that worked very well!

What if you inverse the order of Children in your axes? Basically you would send the rectangle at the "back" of the current axis so you could play around with other elements. When you're done you can switch back. It might not be perfect but I think it would work; from the Matlab doc imrect does not have a HitTest property so maybe that's why using it does not work.

Example code to flip the order of the axes children:

set(gca,'children',flipud(get(gca,'children')))

Thanks to Matt Fig who provided the idea here

I tried with a simple code and 2 rectangles and it worked well.

Thanks for the suggestion, but that didn't work for me. What happened instead is that I couldn't see the rectangle at all, but the rectangle I couldn't see still received the click inside of its area.

Oh I see sorry.

Very happy to have the help! Any suggestions are mana when stuck

Yep! I learned something with Sean's answer ; I did not know the trick to get the Children of imrect that's nice.

NOTE: I created an image in a UIAxes using imagesc:

            app.My_image_handle = imagesc(app.UWBAxes, app.UWBdata);

In that case I do NOT set the HitTest property of children of the image handle. Rather I set it directly on the image handle:

            set(app.My_image_handle,'HitTest','off')
