範例

以下程式碼範例使用導出類別 Panel。 範例中將一個按鈕停靠在面板控制中，並依序切換 ScrollableControl.DockPaddingEdges 屬性，並在點擊按鈕後分別設定每個屬性。 這個例子需要你在表單上建立一個控制項和 a Button 的實例Panel，並且宣告了一個類別myCounter層級的成員變數，命名為一個 32 位元有符號整數。 你應該在 Click 按鈕事件時呼叫這個代碼。

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 )
   {
      case 0:
         panel1->DockPadding->All = 0;
         button1->Text = "Start";
         break;

      case 1:
         panel1->DockPadding->Top = 10;
