Атрибуты

Примеры

В следующем примере кода создаются три элемента управления Button в форме и задаются их размер и расположение с использованием различных свойств, связанных с размером и расположением.The following code example creates three Button controls on a form and sets their size and location by using the various size-related and location-related properties. В этом примере требуется наличие Form с шириной и высотой не менее 300 пикселей.This example requires that you have a Form that has a width and height of at least 300 pixels.

// 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;

Комментарии

Границы элемента управления включают неклиентские элементы, такие как полосы прокрутки, границы, строки заголовка и меню.The bounds of the control include the nonclient elements such as scroll bars, borders, title bars, and menus. Для установки свойства Bounds вызывается метод SetBoundsCore.The SetBoundsCore method is called to set the Bounds property. Свойство Bounds не всегда изменяется с помощью метода set, поэтому следует переопределить метод SetBoundsCore, чтобы обеспечить выполнение кода, если задано свойство Bounds.The Bounds property is not always changed through its set method so you should override the SetBoundsCore method to ensure that your code is executed when the Bounds property is set.
