In bug 1162050, we'd like to remove support for the old non-standard drag events, which were left in for a period of compatibility.
yes please. Anything we can do to simplify dnd code is good. -Olli
The 'draggesture' event should be replaced with the 'dragstart' event (such as ondragstart) The 'dragdrop' event should be replaced with the 'drop' event. If you use these events, they are fired in the same manner as the standard events, so it should be a simple matter of searching and replacing the event names. The non-standard dragexit event will remain as is, as it has no exact standard equivalent. Firefox does not use these events in its code. I filed bug 1171979 for fixing this in Thunderbird and bug 1171980 for fixing this in Seamonkey. If you use these events anywhere or you are the author of an add-on that uses these events, you will need to update your code as described above. The standard drag and drop API is described at: https://html.spec.whatwg.org/multipage/interaction.html#dnd https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Drag_and_drop In addition, we would like to remove the long-deprecated nsDragAndDrop.js script located in toolkit/content in favour of the standard drag and drop API, described at the links above. To ease the transition, if necessary, you may wish to include this script ( https://dxr.mozilla.org/mozilla-central/source/toolkit/content/nsDragAndDrop.js ) directly in your project. Please respond if there are any concerns.
