Beispiele

Im folgenden Beispiel wird die Verwendung der Elemente SetDesktopLocation und Load der ActivateElemente veranschaulicht. Zum Ausführen des Beispiels fügen Sie den folgenden Code in ein Formular Form1 ein, das eine Schaltfläche mit dem Namen Button1 und zwei Label aufgerufenen Label1Label2Steuerelementen enthält.

static int x = 200;
static int y = 200;
void Button1_Click( System::Object^ sender, System::EventArgs^ e )
{
   
   // Create a new Form1 and set its Visible property to true.
   Form1^ form2 = gcnew Form1;
   form2->Visible = true;
   
   // Set the new form's desktop location so it  
   // appears below and to the right of the current form.
   form2->SetDesktopLocation( x, y );
   x += 30;
   y += 30;
   
   // Keep the current form active by calling the Activate
   // method.
   this->Activate();
   this->Button1->Enabled = false;
}


// Updates the label text to reflect the current values of x 
// and y, which was were incremented in the Button1 control's 
// click event.
void Form1_Activated( Object^ sender, System::EventArgs^ e )
{
   Label1->Text = String::Format( "x: {0} y: {1}", x, y );
   Label2->Text = String::Format( "Number of forms currently open: {0}", count );
}

static int count = 0;
void Form1_Closed( Object^ sender, System::EventArgs^ e )
{
   count -= 1;
}

void Form1_Load( Object^ sender, System::EventArgs^ e )
{
   count += 1;
}

    // Set the new form's desktop location so it  
    // appears below and to the right of the current form.
    form2.SetDesktopLocation(x, y);
    x += 30;
    y += 30;

    // Keep the current form active by calling the Activate
    // method.
    this.Activate();

Hinweise

Desktopkoordinaten basieren auf dem Arbeitsbereich des Bildschirms, der die Taskleiste ausschließt. Mit dieser Methode können Sie Ihr Formular auf dem Desktop positionieren. Da Desktopkoordinaten auf dem Arbeitsbereich des Formulars basieren, können Sie diese Methode verwenden, um sicherzustellen, dass Das Formular vollständig auf dem Desktop sichtbar ist. Diese Methode soll hauptsächlich für Formulare auf oberster Ebene verwendet werden; verwenden Sie die LayoutMdi Methode, um untergeordnete MDI-Formulare (Multiple-Document Interface) zu positionieren.
