Member variable DataRef():changed Foundation
Indicates whether data has been changed.
The instance variable :changed contains the value .F. (false) by default. As soon as the edit buffer of an Xbase Part is changed by any input, :changed is set to .T. (true). This can be used to determine whether the edit buffer of an XBP has been changed. The instance variable :changed is automatically reset to .F. (false) when the method :setData() is executed.
