InputPanel.VisibleDesktop 屬性
取得 Rectangle 物件，這個物件表示螢幕輸入面板 (SIP) 未遮蔽的區域。
命名空間： Microsoft.WindowsCE.Forms
組件： Microsoft.WindowsCE.Forms (在 Microsoft.WindowsCE.Forms.dll 中)
語法
'宣告
Public ReadOnly Property VisibleDesktop As Rectangle
'用途
Dim instance As InputPanel
Dim value As Rectangle
value = instance.VisibleDesktop
public Rectangle VisibleDesktop { get; }
public:
property Rectangle VisibleDesktop {
Rectangle get ();
}
public function get VisibleDesktop () : Rectangle
屬性值
表示螢幕輸入面板 (SIP) 未佔用區域的物件。
備註
VisibleDesktop 屬性可提供 Rectangle，其中包含 SIP 未佔用的表單區域大小。啟用 SIP 時，可以重新調整要顯示於這個區域中的控制項之位置或大小。如果您是針對 Pocket PC 以外的 Windows Embedded CE 架構裝置來進行開發，則 VisibleDesktop 屬性會傳回 SIP 未佔用的最大矩形表單區域。如果 SIP 在表單的外面，則 VisibleDesktop 會傳回表單的工作區大小。
範例
下列範例會在 SIP 為啟用時使用 EnabledChanged 事件，以降低索引標籤控制項的高度。停用 SIP 時，它會將索引標籤控制項恢復為原始的高度。範例中會在啟用及停用 SIP 時檢查 VisibleDesktop 屬性，以便調整索引標籤控制項的高度來容納 SIP。這個範例是 InputPanel 元件完整範例的一部分。
