Beispiele

Im folgenden Beispiel wird veranschaulicht, wie die SetDesktopLocationMember und ActivateLoad verwendet werden. Fügen Sie zum Ausführen des Beispiels den folgenden Code in ein Formular einForm1, das eine Schaltfläche mit dem Namen Button1 und zwei Label Steuerelemente mit dem Namen und Label2enthältLabel1.

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;
}

static int x = 200;
static int y = 200;

private void Button1_Click(System.Object sender, 
    System.EventArgs e)

    // Create a new Form1 and set its Visible property to true.
    Form1 form2 = new 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.

    Label2.Text = "Number of forms currently open: "+count;
}

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 Ihr Formular auf dem Desktop vollständig sichtbar ist. Diese Methode soll in erster Linie für Formulare auf oberster Ebene verwendet werden. Verwenden Sie die LayoutMdi -Methode, um untergeordnete MDI-Formulare (Multiple Document Interface) zu positionieren.
