Parameters

Voorbeelden

Het volgende voorbeeld is ontworpen voor gebruik met Windows Forms en vereist PaintEventArgse, een parameter van de Paint gebeurtenis-handler. De code voert de volgende acties uit:

• Hiermee stelt u de tabstops van de StringFormat.

• Hiermee tekent u de tekenreeks en de rechthoek voor de indeling. De tekenreeks bevat tabbladen. De tabinstellingen van de StringFormat opgeven de verschuivingen van de tekst op tabbladen.

• Hiermee haalt u de tabstops op en worden de waarden gebruikt of geïnspecteerd.

Opmerkingen

Elke tabstop-verschuiving in de tabStops matrix, behalve de eerste, is ten opzichte van de vorige. De eerste tabstop-verschuiving is ten opzichte van de initiële offsetpositie die is opgegeven door firstTabOffset. Als de eerste verschuivingspositie bijvoorbeeld 8 is en de eerste tabstop-verschuiving 50 is, bevindt de eerste tabstop zich op positie 58. Als de eerste verschuivingspositie nul is, is de eerste tabstop-verschuiving ten opzichte van positie 0, de oorsprong van de tekenreeks.
