下面的代码示例在窗Button体上创建三个控件,并使用与位置相关的各种属性和位置相关的属性设置其大小和位置。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. 此示例要求具有一个Form宽度和高度至少为300像素的。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()

   // the Size and Location properties.

   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;

注解

控件的边界包括非工作区元素,例如滚动条、边框、标题栏和菜单。The bounds of the control include the nonclient elements such as scroll bars, borders, title bars, and menus. 调用方法来Bounds设置属性。 SetBoundsCoreThe SetBoundsCore method is called to set the Bounds property. 属性并非始终通过其set方法进行更改SetBoundsCore ,因此您应该重写方法,以Bounds确保在设置属性时执行您的代码。 BoundsThe 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.
