TWinControl.OnKeyPress

Handler for a character entered by the user.

Declaration

Source position: controls.pp line 2066

public property TWinControl.OnKeyPress: TKeyPressEvent
  read FOnKeyPress
  write FOnKeyPress;

Description

This handler only receives characters, not control or other special keycodes. Control keys should be handled by an OnKeyDown handler instead.

The handler can convert the character into a different one.

Remark: We recommend you to use OnUTF8KeyPress to prevent data loss. Characters are converted from UTF8 to the system encoding in OnKeyPressEvent, with possible loss of characters outside the Ansi codepage.
