I believe the Qt port already implements this, and that their implementation can be shared with the GTK port. 1580547 1 clopez 2019-10-16 09:41:15 -0700 The spec: https://html.spec.whatwg.org/multipage/dnd.html#the-datatransferitems-interface The Qt implementation was done in r85648 Currently the feature is not longer enabled by a compilation guard. But it has a run-time guard. This run-time is enabled by default on WTR but its disabled for GTK or WPE ports currently otherwise. For Mac is enabled by default. The name of the run-time guard is DataTransferItemsEnabled 1580549 2 clopez 2019-10-16 09:43:26 -0700 The spec: https://html.spec.whatwg.org/multipage/dnd.html#the-datatransferitems-interface The Qt implementation was done in r85648 The feature is not longer enabled by a compilation guard. But it has a run-time guard. This run-time is enabled by default on WTR but its disabled for GTK or WPE ports otherwise (like when using the browser). For Mac is enabled by default. The name of the run-time guard is DataTransferItemsEnabled A layout test to test the feature: editing/pasteboard/data-transfer-items.html 1580596 3 clopez 2019-10-16 11:30:08 -0700 Even when the layout test editing/pasteboard/data-transfer-items.html is not fully passing, the feature seems to mostly work if enabled. Here is a manual test for it: https://mdn.github.io/dom-examples/drag-and-drop/copy-move-DataTransferItemList.html 1580600 4 clopez 2019-10-16 11:36:01 -0700 Here is another test https://mdn.github.io/dom-examples/drag-and-drop/copy-move-DataTransfer.html that passes (this was passing even before enabling the above run-time setting, because that run-time setting now only controls the access to the interface DataTransferItem, but "DataTransfer" is unconditionally enabled) 1580909 5 clopez 2019-10-17 01:17:18 -0700 On r251228 I enabled the runtime setting by default. After that the manual tests above from mdn.github pass on GTK. This bug remains open however, as likely there is something extra to fix or implement regarding this standard because the layout test editing/pasteboard/data-transfer-items.html keeps failing.
