Danke für die Tipps! Sehr hilfreich.

@Joris04 sagte in Probleme mit der stoi Funktion.: Hallo ich habe einen Vektor zz mit strings gefüllt. Daraus will ich einen Buchstaben haben, den in einen String umwandeln um dann die stoi Funktion zu benutzen. Sag' lieber mal was Du machen erreichen willst und lasse das wie weg.

Ich habe mit einem Wacom Bamboo Fun Pen & Touch Small (3. Generation) auf Linux mit Inkscape gearbeitet. Hat funktioniert. Ich habe es schon länger nicht mehr benutzt und weiss daher nicht sicher, ob es noch unterstützt wird. Dieses Gerät wird sicher auch nicht mehr produziert. Für solche Tablets gilt: grösser ist besser.
