.
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.
