Exemples
L’exemple de code suivant montre comment utiliser le Font constructeur et les propriétés, Sizeet SizeInPoints les Unitpropriétés. Cet exemple est conçu pour être utilisé avec un formulaire Windows qui contient un ComboBox nommé ComboBox1 rempli avec les chaînes « Bigger » et « Smaller ». Collez le code suivant dans le formulaire et associez la ComboBox1_SelectedIndexChanged méthode à l’événement SelectedIndexChanged du ComboBox contrôle.
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);
}
}

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":

// and decrease it by 1. Reset the font with the new size
// in points.
