following these two discussions:

https://www.mathworks.com/matlabcentral/answers/712488-drag-and-drop-in-matlab-app-designer-2020b?s_tid=srchtitle

https://www.mathworks.com/matlabcentral/answers/739297-adding-a-title-to-uiimage?s_tid=srchtitle

I decided to try and create my own graphic component. I essentially want it to be a draggable picture with a title.

I tried to follow the instructions here

https://www.mathworks.com/help/matlab/ref/matlab.ui.componentcontainer.componentcontainer-class.html

but encountered some problems.

my first problem is it needs to have something equivalent to a "buttonupfunction" and a "buttondownfunction", and I am not sure how to do this. I am pretty sure it can be done because uiknobs have similar properties.

google has failed me. will be thankful for any assistance

Are you talking of a figure or uifigure? Instead of a dragable image it is much easier to use a dragable axes, which displays an image.

"but encountered some problems" - then please post the code and explain the problems.

thank you for your answer Jan. I am talking about a UIfigure, trying to work with matlab's app designer. for a figure some dragabble solutions already exist. Is it possible to create a dragable axes in a uifigure? how? regarding my problems, I posted another problem here
