Choosing a key/value widget

  • key_value(): a few known values shown in full, such as a summary panel. Not focusable, does not scroll; values are not wrapped.

  • property_grid(): an inspector for many or arbitrary named values. Focusable and scrollable, wraps long values, formats vectors and lists compactly and accepts a format function.

  • record_view(): property_grid() for exactly one record, such as the selected row of a data_table(); accepts a one-row data frame.
