TCustomMaskEdit.HandleKeyPress procedure
Handle all keys from KeyPress and Utf8KeyPress.
Declaration
procedure HandleKeyPress(var Key: TUTF8Char)Arguments
Key | Character value for the key examined in the method. |
Description
HandleKeyPress is a method used to handle keys forwarded from the
KeyPress and
UTF8KeyPress methods. No actions are
performed in the method if the control is
ReadOnly, or
IsMasked returns
False.
HandleKeyPress set the cursor position to the start of the current selection in the control. If the cursor is on a mask literal, it is advanced to the next writable position.
When Key is a Period ('.') or a Comma (',')
character, the cursor is advanced to the next Period or Comma character in
the mask. For other character values, the InsertChar method is called.
The value in Key is set to an empty string ('') when it is handled in the method.
