範例

下列程式碼範例會將 新增 Button 至表單，並設定其一些通用屬性。 此範例會將按鈕錨定在表單的右下角，讓它在表單調整大小時保持其相對位置。 接下來，它會設定 BackgroundImage 按鈕的大小，並將按鈕大小調整為與 Image 相同的大小。 然後範例會將 TabStop 設定為 true ，並設定 TabIndex 屬性。 最後，它會新增事件處理常式來處理 Click 按鈕的事件。 此範例需要您有 ImageList 名為 imageList1 的 。

   // Add a button to a form and set some of its common properties.
private:
   void AddMyButton()
   {
      // Create a button and add it to the form.
      Button^ button1 = gcnew Button;

      // Anchor the button to the bottom right corner of the form
      button1->Anchor = static_cast<AnchorStyles>(AnchorStyles::Bottom | AnchorStyles::Right);

      // Assign a background image.
      button1->BackgroundImage = imageList1->Images[ 0 ];

      // Specify the layout style of the background image. Tile is the default.

      // Make the button the same size as the image.
      button1->Size = button1->BackgroundImage->Size;

      // Set the button's TabIndex and TabStop properties.
      button1->TabIndex = 1;
      button1->TabStop = true;

      // Add a delegate to handle the Click event.

備註

索引標籤索引可以包含任何大於或等於零的有效整數，在製表順序中稍早的數位。 如果相同父控制項上的多個控制項具有相同的索引標籤索引，控制項的 Z 順序會決定要迴圈執行控制項的順序。

若要讓控制項包含在定位順序中，其 TabStop 屬性必須設定為 true 。
