Ejemplos

En el ejemplo de código siguiente se muestra cómo usar el Font constructor y las Sizepropiedades , SizeInPointsy Unit . Este ejemplo está diseñado para usarse con un formulario Windows Forms que contiene un ComboBox nombre ComboBox1 que se rellena con las cadenas "Bigger" y "Smaller" y con un Label denominado Label1. Pegue el código siguiente en el formulario y asocie el ComboBox1_SelectedIndexChanged método con el SelectedIndexChanged evento del ComboBox control.

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;
            Label1->Font = gcnew System::Drawing::Font(Label1->Font->Name, 
                currentSize, Label1->Font->Style);

        }
    }

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;

    // Switch on the selected item. 
    switch(selectedString)
    {

            // 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.
        case "bigger":
            currentSize = Label1.Font.Size;
            currentSize += 2.0F;
            Label1.Font = new Font(Label1.Font.Name, currentSize, 
                Label1.Font.Style, Label1.Font.Unit);

            // If Smaller is selected, get the current size, in points,

Comentarios

Para obtener más información sobre cómo construir fuentes, vea Cómo: Construir familias de fuentes y fuentes. Windows Forms las aplicaciones admiten fuentes TrueType y tienen compatibilidad limitada con fuentes OpenType. Si intenta usar una fuente que no es compatible o la fuente no está instalada en el equipo que ejecuta la aplicación, se sustituirá la fuente Microsoft Sans Serif.
