Im folgenden Codebeispiel werden drei Button Steuerelemente in einem Formular erstellt und deren Größe und Position mithilfe der verschiedenen Eigenschaften mit Größe und Position festgelegt. In diesem Beispiel ist erforderlich, dass Sie über Form eine Breite und Höhe von mindestens 300 Pixeln verfügen.

// Create three buttons and place them on a form using
// several size and location related properties.
void AddOKCancelButtons()
{
   
   // Set the button size and location using
   // the Size and Location properties.
   Button^ buttonOK = gcnew Button;
   buttonOK->Location = Point(136,248);
   buttonOK->Size = System::Drawing::Size( 75, 25 );
   
   // Set the Text property and make the
   // button the form's default button.
   buttonOK->Text = "&OK";
   this->AcceptButton = buttonOK;
   
   // Set the button size and location using the Top,
   // Left, Width, and Height properties.
   Button^ buttonCancel = gcnew Button;
   buttonCancel->Top = buttonOK->Top;
   buttonCancel->Left = buttonOK->Right + 5;
   buttonCancel->Width = buttonOK->Width;
   buttonCancel->Height = buttonOK->Height;

   buttonHelp->Bounds = Rectangle(10,10,75,25);
   
   // Set the Text property of the button.
   buttonHelp->Text = "&Help";
   
   // Add the buttons to the form.

Hinweise

Änderungen, die an den Werten der Height Eigenschaft vorgenommen wurden, Top führen dazu, dass der Bottom Eigenschaftswert des Steuerelements geändert wird.

Hinweis

Die Mindesthöhe für das abgeleitete Steuerelement Splitter ist ein Pixel. Die Standardhöhe für das Splitter Steuerelement ist drei Pixel. Wenn Sie die Höhe des Splitter Steuerelements auf einen Wert kleiner als ein Wert festlegen, wird der Eigenschaftswert auf die Standardhöhe zurückgesetzt.
