Exempel

Följande kodexempel visar hur du använder Font konstruktorn och Sizeegenskaperna , SizeInPointsoch Unit . Det här exemplet är utformat för att användas med ett Windows formulär som innehåller en ComboBox med namnet ComboBox1 som fylls med strängarna "Större" och "Mindre" och en Label med namnet Label1. Klistra in följande kod i formuläret och associera ComboBox1_SelectedIndexChanged metoden med SelectedIndexChanged kontrollens ComboBox händelse.

private:
    void ComboBox1_SelectedIndexChanged(System::Object^ sender,
        System::EventArgs^ e)
    {

        // Cast the sender object back to a ComboBox.
        ComboBox^ ComboBox1 = (ComboBox^) sender;

        // Retrieve the selected item.
        String^ selectedString = (String^) ComboBox1->SelectedItem;

        // Convert it to lowercase.
        selectedString = selectedString->ToLower();

        // Declare the current size.
        float currentSize;

        // If Bigger is selected, get the current size from the 
        // Size property and increase it. Reset the font to the
        //  new size, using the current unit.
        if (selectedString == "bigger")
        {
            currentSize = Label1->Font->Size;
            currentSize += 2.0F;
            Label1->Font =gcnew System::Drawing::Font(Label1->Font->Name, 
                currentSize, Label1->Font->Style, Label1->Font->Unit);

        }
        // If Smaller is selected, get the current size, in
        // points, and decrease it by 2.  Reset the font with
        // the new size in points.
        if (selectedString == "smaller")
        {
            currentSize = Label1->Font->Size;
            currentSize -= 2.0F;

                currentSize, Label1->Font->Style);

        }

Mer information om hur du skapar teckensnitt finns i Så här skapar du teckensnittsfamiljer och teckensnitt. Windows Forms program stöder TrueType-teckensnitt och har begränsat stöd för OpenType-teckensnitt. Om du försöker använda ett teckensnitt som inte stöds eller om teckensnittet inte är installerat på datorn som kör programmet ersätts teckensnittet Microsoft Sans Serif.
