Carefully review and enhance the code below to perform the bidirectional binding between the TComponent property changes and its corresponding TQryRecInfo descendant property.
I need this code to operate to perform bidirectional update, following some rules:
if the TQryRecInfo descendant property is mapped to a TEdit, then this property maps to the TEdit.Text
if the TQryRecInfo descendant property is mapped to a TLabel, then this property maps to the TLabel.Caption
if the TQryRecInfo descendant property is mapped to a TDatePicker, then this property maps to the TDatePicker.Date
and so on...
When the TQryRecInfo descendant property is not a string, but it should map to a string TComponent property, then use GetFormattedText to convert to its string representation
For binding, use the interposer_class unit methods/ideas when possible
