Zastanawiam się jak mogę napisać Edytor html Visiting. Wyobrażam sobie to tak. W RichEdit mogę formatować tekst w sposób wizualny (potraktować go bodem, pochylić, zmienić kolor, czy zmienić czcionke itp. Ale nie mam pojęcia jak tak sformatowany tekst zamienić na html. Proszę o jakąs podpowiedź
hmm, czytasz znak po znaku, sprawdzasz gdzie sie zmieniaja style i jak, dajesz to do html :). RE nie ma wiele mozliwosci, wiec duzo roboty chyba nie bedzie.

hmm, czytasz znak po znaku, sprawdzasz gdzie sie zmieniaja style i jak, dajesz to do html :). RE nie ma wiele mozliwosci, wiec duzo roboty chyba nie bedzie.
Zastanawiam się jak mogę napisać Edytor html Visiting. Wyobrażam sobie to tak. W RichEdit mogę formatować tekst w sposób wizualny (potraktować go bodem, pochylić, zmienić kolor, czy zmienić czcionke itp. Ale nie mam pojęcia jak tak sformatowany tekst zamienić na html. Proszę o jakąs podpowiedź
