browser(_:writeRowsWith:inColumn:to:)

Determines whether a drag operation can proceed. This method is required for a browser to be a drag source.

Declaration

@MainActor optional func browser(_ browser: NSBrowser, writeRowsWith rowIndexes: IndexSet, inColumn column: Int, to pasteboard: NSPasteboard) -> Bool

Parameters

  • browser:

    The browser.

  • rowIndexes:

    The indexes of the rows the user is dragging.

  • column:

    The index of the column containing the dragged rows.

  • pasteboard:

    The pasteboard containing the content from the dragged rows.

Return Value

true to allow the dragging operation to proceed (see discussion for further details); false to disallow it.

Discussion

This method is called after a drag operation has been allowed to start (browser(_:canDragRowsWith:inColumn:with:) returns true), but before it actually begins.
