示例

下面的代码示例使用派生类 Panel。 该示例将按钮停靠在面板控件中，并循环访问 ScrollableControl.DockPaddingEdges 属性，在单击按钮时单独设置每个属性。 此代码要求 Panel 控件和 Button 已在窗体上实例化，并且名为 的 myCounter 类级成员变量已声明为 32 位带符号整数。 应在按钮的 事件上 Click 调用此代码。

void SetDockPadding()
{
   // Dock the button in the panel.
   button1->Dock = System::Windows::Forms::DockStyle::Fill;

   // Reset the counter if it is greater than 5.
   if ( myCounter > 5 )
   {
      myCounter = 0;
   }


   /* Set the appropriate DockPadding and display
          which one was set on the button face. */
   switch ( myCounter )

注解

类 ScrollableControl.DockPaddingEdges 在停靠控件的给定边缘或所有边缘上创建边距。 可以通过设置以下属性为每个单独的边缘设置此边距的宽度：Bottom、、Top、LeftRight。 或者，可以通过设置 All 属性同时将所有边缘设置为相同的宽度。 如果控件的大小对于其容器来说太大，则将调整控件的大小以适应容器中，减去指定的边距宽度。

属性

All	获取或设置停靠控件的所有边缘的边距宽度。
Bottom	获取或设置停靠控件的下边缘的边距宽度。
Left	获取或设置停靠控件的左边缘的边距宽度。
Right	获取或设置停靠控件的右边缘的边距宽度。
Top	获取或设置停靠控件的顶边缘的边距宽度。

方法

Equals(Object)	此 API 支持产品基础结构，不能在代码中直接使用。 确定指定的对象是否等于当前 ScrollableControl.DockPaddingEdges 对象。
GetHashCode()	用作特定类型的哈希函数。
GetType()	获取当前实例的 Type。 (继承自 Object)
MemberwiseClone()	创建当前 Object 的浅表副本。 (继承自 Object)
ToString()	返回空字符串。

显式接口实现

ICloneable.Clone()

创建作为当前实例副本的新对象。
