Lightweight primitive enabling drag-based selection with visual rectangle, consuming drag gestures to prevent parent scroll conflicts, optional hit-testing, and fully customizable selection styling.
A lightweight Jetpack Compose utility that enables drag-based selection by drawing a selection rectangle and consuming drag gestures to prevent parent scroll or drag conflicts.
Designed as a low-level primitive, this library helps you build selection-based UX such as editors, canvases, dashboards, and boards — without enforcing any opinionated UI or behavior.

# Quick Start
DragHighlightBox(
enabled = true,
onSelectionEnd = { rect ->
// Handle selection rectangle
}
) {
// Your composable content
}
You can customize how the selection rectangle looks using DragFeedbackStyle:
DragHighlightBox(
style = DragFeedbackStyle(
fillColor = Color(0x3388BFFF),
strokeColor = Color(0xFF66AFFF),
strokeWidthPx = 2f
),
onSelectionEnd = { rect -> }
) {
CanvasContent()
}
To prevent selection from starting when the user drags an item (instead of empty space), use canStartSelection:
DragHighlightBox(
canStartSelection = { downOffset ->
items.none { it.bounds.contains(downOffset) }
},
onSelectionEnd = { rect -> }
) {
CanvasContent()
}
A desktop demo application is included in the repository to showcase integration patterns and usage. The demo is not part of the published library.
