屬性值

型別：Microsoft.Ink.Cursors
可用於筆墨區域的 Cursors 集合。

備註

每個游標對應於畫筆或其他筆墨輸入裝置的筆尖。

在這個集合中的游標都是 InkPicture 控制項的區域游標。

InkPicture 控制項所遇到的任何新游標都會加入至傳回的 Cursors 集合，然而不一定會按照 InkPicture 控制項遇到這些游標的順序傳回它們。

當您在 InkPicture 控制項上啟用滑鼠做為輸入裝置時 (即 SetAllTabletsMode 方法的 useMouseForInput 參數為 true 時)，滑鼠會在 InkPicture 遇到任何其他游標 (如畫筆) 之後被加入至 Cursors 集合。這是因為畫筆也可以做為滑鼠使用。

注意事項：
在任何其他游標之後的滑鼠游標會收到 CursorInRange 事件，例如，當畫筆繪製筆劃 (會引發 Stroke 事件) 時。

在下列情況下，會清除 Cursors 集合 (計數設定為 0，不包含任何物件)：

手寫板模式已變更 (例如，從 SetSingleTabletIntegratedMode 變更為 SetAllTabletsMode)。
呼叫 SetSingleTabletIntegratedMode 方法。
