InputPanel.EnabledChanged 事件

在啟用或停用螢幕小鍵盤 (SIP) 時發生。

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

語法

'宣告
Public Event EnabledChanged As EventHandler
'用途
Dim instance As InputPanel
Dim handler As EventHandler

AddHandler instance.EnabledChanged, handler

public event EventHandler EnabledChanged

public:
 event EventHandler^ EnabledChanged {
    void add (EventHandler^ value);
    void remove (EventHandler^ value);
}

JScript 不支援事件。

備註

每當以程式設計方式或由使用者啟用或停用 SIP 時，即會發生 EnabledChanged 事件。發生這個事件時，您可以判斷 SIP 是啟用還是停用，並適當重新調整控制項的位置或大小。

您可以變更 Enabled 屬性，引發這個事件。

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。這個範例是 InputPanel 元件完整範例的一部分。

Private Sub InputPanel1_EnabledChanged(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles InputPanel1.EnabledChanged
 If InputPanel1.Enabled = False Then

  ' The SIP is disabled, so set the height of the tab control
  ' to its original height with a variable (TabOriginalHeight),
  ' which is determined during initialization of the form.
  VisibleRect = InputPanel1.VisibleDesktop
  TabControl1.Height = TabOriginalHeight
 Else
  ' The SIP is enabled, so the height of the tab control
  ' is set to the height of the visible desktop area.
  VisibleRect = InputPanel1.VisibleDesktop
  TabControl1.Height = VisibleRect.Height
 End If

 ' The Bounds property always returns a width of 240 and a height of 80
 ' pixels for Pocket PCs, regardless of whether or not the SIP is enabled.
 BoundsRect = InputPanel1.Bounds

 ' Show the VisibleDesktop and Bounds values
 ' on the second tab for demonstration purposes.
       VisibleInfo.Text = String.Format("VisibleDesktop: X = {0}, " _
       & "Y = {1}, Width = {2}, Height = {3}", _
       VisibleRect.X, VisibleRect.Y, _
       VisibleRect.Width, VisibleRect.Height)
       BoundsInfo.Text = String.Format("Bounds: X = {0}, Y = {1}," _
          & "Width = {2}, Height = {3}", BoundsRect.X, BoundsRect.Y, _
          BoundsRect.Width, BoundsRect.Height)
End Sub

private void inputPanel1_EnabledChanged(object sender, EventArgs e)
{
    if (inputPanel1.Enabled == false)
    {
        // The SIP is disabled, so set the height of the tab control
        // to its original height with a variable (TabOriginalHeight),
        // which is determined during initialization of the form.
        VisibleRect = inputPanel1.VisibleDesktop;
        tabControl1.Height = TabOriginalHeight;
    }
    else
    {
        // The SIP is enabled, so the height of the tab control
        // is set to the height of the visible desktop area.
        VisibleRect = inputPanel1.VisibleDesktop;
        tabControl1.Height = VisibleRect.Height;
    }

    // The Bounds property always returns a width of 240 and a height of 80
    // pixels for Pocket PCs, regardless of whether or not the SIP is enabled.
    BoundsRect = inputPanel1.Bounds;

    // Show the VisibleDestkop and Bounds values
    // on the second tab for demonstration purposes.
    VisibleInfo.Text = String.Format("VisibleDesktop: X = {0}, " +
        "Y = {1}, Width = {2}, Height = {3}", VisibleRect.X,
        VisibleRect.Y, VisibleRect.Width, VisibleRect.Height);
    BoundsInfo.Text = String.Format("Bounds: X = {0}, Y = {1}, " +
        "Width = {2}, Height = {3}", BoundsRect.X, BoundsRect.Y,
        BoundsRect.Width, BoundsRect.Height);
}
