TabControlArray.DrawItem 事件

定義

如果 TabControl 屬性設定為 DrawMode,在 OwnerDrawFixed 需要繪製它的每一個索引標籤時發生。Occurs when the TabControl needs to paint each of its tabs if the DrawMode property is set to OwnerDrawFixed.

public:
 event System::Windows::Forms::DrawItemEventHandler ^ DrawItem;
public event System.Windows.Forms.DrawItemEventHandler DrawItem;
member this.DrawItem : System.Windows.Forms.DrawItemEventHandler 
Public Event DrawItem As DrawItemEventHandler 

備註

當您將 [DrawMode] 屬性設定為 [OwnerDrawFixed] 時,TabControl 會在需要繪製其其中一個索引標籤時引發 DrawItem 事件。When you set the DrawMode property to OwnerDrawFixed, the TabControl raises the DrawItem event whenever it needs to paint one of its tabs. 若要自訂索引標籤的外觀,請在 DrawItem 事件的處理常式中提供您自己的繪製程式碼。To customize the appearance of the tabs, provide your own painting code in a handler for the DrawItem event.

TabControl 不支援具有擁有者繪製的變數索引標籤大小。The TabControl does not support variable tab sizes with owner drawing.
