Exemplos

O exemplo de código a seguir cria pontos e tamanhos usando vários operadores sobrecarregados definidos para esses tipos.The following code example creates points and sizes using several of the overloaded operators defined for these types. Ele também demonstra como usar a SystemPens classe.It also demonstrates how to use the SystemPens class.

Este exemplo foi projetado para ser usado com Windows Forms.This example is designed to be used with Windows Forms. Crie um formulário que contenha um Button nome subtractButton .Create a form that contains a Button named subtractButton. Cole o código no formulário e chame o CreatePointsAndSizes método do método de manipulação de Paint eventos do formulário, passando e como PaintEventArgs .Paste the code into the form and call the CreatePointsAndSizes method from the form's Paint event-handling method, passing e as PaintEventArgs.

void CreatePointsAndSizes( PaintEventArgs^ e )
{
   // Create the starting point.
   Point startPoint = Point(subtractButton->Size);
   
   // Use the addition operator to get the end point.
   Point endPoint = startPoint + System::Drawing::Size( 140, 150 );
   
   // Draw a line between the points.
   e->Graphics->DrawLine( SystemPens::Highlight, startPoint, endPoint );
   
   // Convert the starting point to a size and compare it to the
   // subtractButton size.  
   System::Drawing::Size buttonSize = (System::Drawing::Size)startPoint;
   if ( buttonSize == subtractButton->Size )
   {
      e->Graphics->DrawString( "The sizes are equal.", gcnew System::Drawing::Font( this->Font,FontStyle::Italic ), Brushes::Indigo, 10.0F, 65.0F );
