Is your feature request related to a problem?

I display images in a canvas object. I want to be able to capture mouse clicks on the image. That is possible for widgets, but not a canvas. The overlay container seems to provide the exact functionality I need: it's a tappable widget containing a CanvasObject. The overlay (I gather) can be transparent, so the image can be seen, but as the overlay is a widget, it can be tappable. That is likely to provide the functionality I'm looking for.

Is it possible to construct a solution with the existing API?

I've looked but found only the NewOverlayContainer(), but it's an 'internal' function.

Describe the solution you'd like to see.

Can I take some of 'internal' code and put it in my program? I assume there's danger here and the 'internal' status is a "dragons lurk here' sign.

If you want a tappable image, it is a lot better to just make a widget out of it and make that widget extend the fyne.Tappable interface. See https://pkg.go.dev/fyne.io/x/fyne@v0.0.0-20231231230942-0b5901d0781a/wrapper#MakeTappable for example (looking at the code might also be useful).

See also https://github.com/dweymouth/supersonic/blob/785e651dd64b5edc690fcae3b4f24168ccc1cff3/ui/widgets/tappablewrappers.go#L53 for a TappableImage implementation as a custom widget. In contrast to the MakeTappable implementation, this tappable image can easily be further extended to add additional functionality (hoverable, etc)

The MakeTappable func sounds like the answer, but what package is it in? wrapper.MakeTappable() fails. What would work?

You need to add the fyne-x repo to your go.mod. fyne-x is the repo for community extensions to the toolkit

Please be more complete. Exactly what entry do I make in go.mod?

Just import fyne.io/x/fyne/wrapper using go get
