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

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
(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 e.g. a non-standard clipboard-swap operation. However I'll
revisit "the proper way" when some of the dust has settled, one
particular thing that I'll want to check is what happens when one runs
with e.g. a Sun keyboard which has explicit cut/copy keys.
