Drag & Drop in macOS support [to copy URL]

Goetz · June 23, 2026, 4:55pm

Expected behavior

When dragging an URL from Firefox/macOS or Safari/macOS to the edit field of a chat in DC, the mouse cursor changes to indicate a Drop target. Dropping the URL here inserts it into the editfield.
Optional: remove tracking information
My dad expects this, as iMessage and Mail behave the described way.

Actual behavior

Dropping the URL doesn’t do anything. No (web URL) text is inserted.

Probably can be handled in this function. We only handle files currently:

github.com/deltachat/deltachat-desktop

packages/target-browser/runtime-browser/runtime.ts

          document.body.addEventListener('drop', async e => {
            this.log.debug('drop event', { target: e.target }, this.onDrop)
            if (!this.onDrop) {
              this.log.warn('file dropped, but no drop handler set')
              return
            }
            const dropTarget = this.onDrop.elementRef.current
            if (!dropTarget) {
              this.log.warn('file dropped, but drop target is unset')
              return
            }
            if (!e.dataTransfer) {
              this.log.debug('dropped, but no data transfer')
              return
            }
            if (!(e.target && dropTarget.contains(e.target as HTMLElement))) {
              this.log.debug(
                'file dropped, but it was dropped outside of the drop target element'
              )
              return

FYI this is not specific to macOS.

For comparison, Element also only handles files apparently (see code).
