Remove .pointerInteropFilter - #183
Conversation
Allows user to drag to scroll on top of chart (cherry picked from commit 5bb92e6) Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Wpm5WJmH8cgLjNAF82tqXP
📝 WalkthroughWalkthroughThe change removes the obsolete cross-platform pointer interop abstraction and its platform implementations. ChangesPointer interop cleanup
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The change removes the public pointerInteropFilter API and may still consume drags begun outside chart bars, causing downstream compilation failures or blocked parent scrolling.

- Around line 207-209: Update the pointer handling around detectDragGestures in
RowChart so drags beginning outside chart bars do not consume pointer changes
and remain available to a vertically scrollable parent. Consume movement only
after lastOrNull identifies a bar, while preserving existing drag selection
behavior for bar hits.

🌐 Web query:
site:developer.android.com/reference/kotlin/androidx/compose/foundation/gestures/detectDragGestures "consume"
💡 Result:
detectDragGestures automatically consumes position changes after touch slop is crossed, so you generally should not call change.consume() inside onDrag. It also cancels if another gesture consumes the pointer input. (developer.android.com)
Modifier.pointerInput(Unit) {
detectDragGestures { change, dragAmount ->
// change.positionChange() is already consumed by the detector
offset += dragAmount
}
}If you need manual control over consumption, use lower-level APIs such as awaitTouchSlopOrCancellation or drag.
Citations:
Preserve parent scrolling for drags outside bars.
When popupProperties.enabled is true, the full-size Canvas installs detectDragGestures. The detector consumes position changes after touch slop even when lastOrNull finds no bar. A drag that starts on empty chart space can therefore prevent a vertical scrollable parent from scrolling. Use a custom pointer loop that consumes changes only after a bar hit test succeeds, or disable drag selection when parent scrolling must win.

The
.pointerInteropFilterbreaks scrolling on the row charts and seems like it's an artifact of some discarded work. Removing it fixes the scrolling.A few things:
I got tripped up by the wildcard expansion, so I added a .editorconfig to keep this consistent.
The formatting in
RowChartwas funky, so this change is actually much smaller than it looks like.This is technically ABI/API breaking if someone used the
.pointerInteropFilterin their own code. I'm not sure why they would've, but if you're worried about that, I can make it a noop and deprecated instead of removing it.
