Examples

The following code example demonstrates using the MinSize, MaxSize, ShowEffects and FontMustExist members and handling the Apply event. To run this example paste the following code in a form containing a FontDialog named FontDialog1 and a Button named Button1.

void Button1_Click( System::Object^ sender, System::EventArgs^ e )
{
   // Set FontMustExist to true, which causes message box error
   // if the user enters a font that does not exist. 
   FontDialog1->FontMustExist = true;
   
   // Associate the method handling the Apply event with the event.
   FontDialog1->Apply += gcnew System::EventHandler( this, &Form1::FontDialog1_Apply );
   
   // Set a minimum and maximum size to be
   // shown in the FontDialog.
   FontDialog1->MaxSize = 32;
   FontDialog1->MinSize = 18;
   
   // Show the Apply button in the dialog.
   FontDialog1->ShowApply = true;
   
   // Do not show effects such as Underline
   // and Bold.
   FontDialog1->ShowEffects = false;
   
   // Save the existing font.
   System::Drawing::Font^ oldFont = this->Font;
   
   //Show the dialog, and get the result
   System::Windows::Forms::DialogResult result = FontDialog1->ShowDialog();
   
   // If the OK button in the Font dialog box is clicked, 
   // set all the controls' fonts to the chosen font by calling
   // the FontDialog1_Apply method.
   if ( result == ::DialogResult::OK )
   {
      FontDialog1_Apply( this->Button1, gcnew System::EventArgs );
   }
   // If Cancel is clicked, set the font back to
   // the original font.
   else
   
   // If Cancel is clicked, set the font back to
   // the original font.
   if ( result == ::DialogResult::Cancel )
   {
      this->Font = oldFont;
      System::Collections::IEnumerator^ myEnum = this->Controls->GetEnumerator();
      while ( myEnum->MoveNext() )
      {

         containedControl->Font = oldFont;
      }
