Update: I solved this for now by adding a line to the "update" function that sets the Parent of the panel to be the Parent figure rather than the object itself. namely:
however I am worried that this might cause bugs in the future
original question:
I am trying to create a custom UI component. so far I simply tried to integrate a panel with a UIImage.
however, my custom component stubbornly refuses to appear on the screen. in other cases it appears on the screen but the title of the panel is not there.
I am attaching my code, as well as my resulting figures. in my main script I also run the exact same commands directly and the figure indeed appears.
Thanks in advance

" set(obj.Panel,'Parent',obj.Parent)

You're absolutely right. This is not a good idea.
Your problem is that the panel's default units are "normalized" so setting anything outside the bounds of 0 and 1 results in something way off-screen (of the componentcontainer object). In your panel constructor call, set the units to pixels before setting the position property.
Better yet, I strongly encourage the use of uigridlayout. Every componentcontainer I build starts with a grid. Using grids makes nearly every conversation about size and position irrelevant. It also cures practically every situation such as this one - "what's wrong with my component positioning?".

thank you for your answer Greg. while you are here, I wonder if I could piggyback the question with another one.
is there a way to set a "mouse released" function in my custom component? there used to be one in the old buttons for the guide, but there isn't one in the new uibuttons
