Changing is a method used to perform actions needed when property values in the component are being updated. It mimics the Changing behavior implemented in TStringList, where methods call Changing prior to updates to the Strings or Objects properties.
In TTextStrings, the method signals the OnChanging event handler (when assigned) if there are no updates already in progress.
See Changed for the actions performed after property values have been updated.
