TDBMemo.KeyPress Method
|
RAD Studio VCL Reference
|
|
|
KeyPress overrides the inherited method to handle any keystrokes that alter the state of the edit control.
procedure KeyPress(var Key: Char); override;
virtual __fastcall KeyPress(Char Key);
KeyPress first calls the inherited method, which calls the OnKeyPress event handler. Next, KeyPress checks the value of the key, and throws it away if it is not a valid character for the field type, or if there is no link to a database field. Valid characters cause KeyPress to attempt to put the dataset into edit mode.
If the field for the memo control is a text BLOB, pressing the Pause key causes KeyPress to call the LoadMemo method. Pressing the Escape key causes KeyPress to throw away unposted edits.
