描述

Hi, I am using ui-grid (v4.0.2 - 2016-12-30) with a linux touchscreen device, running chrome. My setup includes the following:

enableColumnMenus: false, enableFiltering: false, enableExpandableRowHeader: false, expandableRowTemplate: 'orderActions.html', expandableRowHeight: 35, enableRowSelection : true, selectionRowHeaderWidth: 0, enableFullRowSelection: true, multiSelect: false,

also, I expand a row upon selection. Everything works fine on a normal with mouse, but when I use the touchscreen to scroll, sometimes (especially on momentum scrolling action) rows are being selected when I only intend to scroll (drag).

研究方向
Investigate the touch event handling in the ui grid, specifically how scroll gestures are distinguished from selection gestures. Look at the row selection logic in the source code (e.g., GridRow.js or SelectionService). Consider reproducing the issue with a touchscreen device to understand the event flow. Check if there are existing fixes or related PRs.
