The drop location should be tracked in terms of the index of existing items. Useful for dropping on items in tables, lists, and trees.

The drop location should be tracked in terms of the position where new data should be inserted. For components that manage a list of items (list and tree for example), the drop location should indicate the index where new data should be inserted. For text components the location should represent a position between characters. For components that manage tabular data (table for example), the drop location should indicate where to insert new rows, columns, or both, to accommodate the dropped data.

The drop location should be tracked in terms of the row index where new rows should be inserted to accommodate the dropped data. This is useful for components that manage tabular data.

The drop location should be tracked in terms of the column index where new columns should be inserted to accommodate the dropped data. This is useful for components that manage tabular data.
