I'm in the middle of adding a shared clipboard to a text editor

listen/notify and hopefully also the Firebird equivalent both of
which I want for something else.
What I've got works fine if I use a menu entry to do copy or cut,
but is there a simple way to hook SynEdit's reaction to ^C and ^X so
that I can transfer stuff to the backend automatically?
OnProcessCommand
this is during keyboard processing too.
SynEdit will have translated it int ecCopy
(if not that then OnProcessUserCommand commands are splitted into
build in and user. ecCopy ecCut ecPaste should be build in)
The above only works if lynedit handles the keyboard.
If you call SynEdit.CopyToClipboard (TAction might do that?) then the
above does not trigger
use
property OnCutCopy: TSynCopyPasteEvent read FOnCutCopy write
FOnCutCopy;
property OnPaste: TSynCopyPasteEvent read FOnPaste write FOnPaste;
Thanks Martin, noted. As an interim measure I ended up detecting ^C
etc. in the key-up event, which /might/ be safer since I'm already
filtering keys to implement an APL-style keyboard and /might/ be the
only way to handle
IIRC SynEdit handles ctrl-c in keydown
You can prevent SynEdit from handling the keystroke, by removing it from
SynEdit,KeyStrokes (or similar)
