combinedClickable

and

mouseClickable

are mutually exclusive, but have non-overlapping functionality. Is there a built-in way to handle both double-clicks and right-clicks on an item?

One thing to remember - right click is not the same as show-context-menu. On macOS for example, context menu should also be shown on Ctrl+left click. There's also the difference between when the context menu should be shown (mouse press or mouse release) on Windows vs macOS

Good points! I hadn't thought about macOS because my support for it will be dubious (due to doing a lot of file io and not having a mac to test with).

I created a function like this, that can do whatever you like.

Modifier
    .pointerInput(Unit) {
        forEachGesture {
            awaitPointerEventScope {
                awaitFirstDown()
                do {
                    val event = awaitPointerEvent()
                    // detect mouse buttons and keyboard modifiers here:
                    // event.buttons.xxxx
                    // event.keyboard.Modifiers.xxxx
                    // event.***  :-D
                } while (event.changes.any { it.pressed })
            }
        }
    }

Thanks, I'll copy/paste from

PointerInputScope.detectTapGestures

to add double-click detection and hopefully this will be added to the easy-to-use APIs in the future.
