[lazarus] Sniffing Synedit Tokens

2006-03-11 Thread L505 
Hi when a Var parameter is to be passed, holding a TPersistent object like below
(tmpattr)...

  syn1.GetHighlighterAttriAtRowCol(syn1.CaretXY, tmpstring, tmpattr);

..is it wrong to create tmpattr first? Is it just a reference to an existing
TSynHighlighterAttributes

When I create and free a storage 'tmpattr' I get access violation and this is
why I'm wondering.

Actually, the parameter coud/should be 'out' (but I guess FPC doesn't
even implement the COM-ish things ;-)
It has nothing to do with 'var' and 'TPersistent', the problem is the
object returned in 'tmpattr' the actual object owned by the
highlighter, so if you free it this will generate an AV the next time
the highlighter is used (e.g. the editor is painted).

'out' is implemented and used.
