TCustomEdit.TextChanged procedure
Applies case conversion (if needed), and updates the editing cursor selection text.
Declaration
procedure TextChanged; overrideDescription
TextChanged is a an overridden method used to perform actions
needed when the
CM_TEXTCHANGED message is handled for the control. No
actions are performed in the method when a previous call to TextChanged has
not been completed.
TextChanged uses the value in CharCase to determine if case
conversion is applied to the value in Text. When CharCase contains
ecUpperCase or ecLowerCase, the corresponding UTF-8
conversion routine is called. When Text is modified in the method, the values
in CaretPos, SelStart, and SelLength are
re-applied to the control. At run-time, the value in Modified is
set to True when Text has been changed in the method.
