Cursor.Inverted 屬性

取得值，這個值表示游標是否為畫筆的反轉端。

命名空間：  Microsoft.Ink
組件：  Microsoft.Ink (在 Microsoft.Ink.dll 中)

語法

'宣告
Public ReadOnly Property Inverted As Boolean
'用途
Dim instance As Cursor
Dim value As Boolean

value = instance.Inverted

public bool Inverted { get; }

public:
property bool Inverted {
    bool get ();
}

/** @property */
public boolean get_Inverted()

public function get Inverted () : boolean

屬性值

型別：System.Boolean
如果游標是畫筆的反轉端，則為 true，如果游標不是畫筆的反轉端，或者畫筆不支援與畫筆之反轉端相關聯的游標，則為 false。

備註

反轉游標通常與擦去動作相關聯，因此已知畫筆可能有一端用來繪製筆墨，另一端用來擦去筆劃。不過，系統辨識畫筆反轉端的行為不限於擦去。您可以將任何可接受的游標行為與 Inverted 屬性產生關聯。

如需擦去筆墨的詳細資訊，請參閱Erasing Ink with the Pen。

注意事項：
您是否要使用 Inverted 屬性完全視應用程式需要而定。應用程式不需要檢查反轉游標，而且「筆墨收集器」會將預設繪圖屬性套用至反轉游標，就像處理非反轉游標時一樣。

注意事項：
如果在特定訊息處理常式內呼叫的話，可能會重新輸入這個函式，造成非預期的結果。處理下列訊息時，請小心避免使用可重新進入的呼叫：WM_ACTIVATE、WM_ACTIVATEAPP、WM_NCACTIVATE、WM_PAINT、WM_SYSCOMMAND (如果 wParam 設定為 SC_HOTKEY 或 SC_TASKLIST) 和 WM_SYSKEYDOWN (處理 ALT+TAB 或 ALT+ESC 組合鍵時)。不過在單一執行緒 Apartment Model (STA) 應用程式中會發生問題。

範例

這個 C# 範例會傳回一份報告，內容是關於做為參數傳入之 InkCollector 物件遭遇的所有游標屬性。

using Microsoft.Ink;

public string CursorReport(InkCollector theInkCollector)
{
    string theReport = "The InkCollector has encountered the following cursors so far:" + Environment.NewLine;
    // Get the Cursors collection from the InkCollector
    Microsoft.Ink.Cursors theCursors = theInkCollector.Cursors;
    // Prevent changes to the collection while we iterate over it.
    lock( theCursors.SyncRoot )
    {
        theReport += "Count of cursors: " + theCursors.Count + Environment.NewLine + Environment.NewLine ;
        foreach (Microsoft.Ink.Cursor cursor in theCursors)
