Control.MousePosition 屬性

定義

命名空間:

System.Windows.Forms

組件:

System.Windows.Forms.dll

取得滑鼠游標在螢幕座標中的位置。

public:
 static property System::Drawing::Point MousePosition { System::Drawing::Point get(); };

public static System.Drawing.Point MousePosition { get; }

member this.MousePosition : System.Drawing.Point

Public Shared ReadOnly Property MousePosition As Point

屬性值

Point

Point，包含與螢幕左上角相對的滑鼠游標座標。

範例

下列程式碼範例會在使用者按下 ALT+E，而滑鼠游標位於樹狀節點上方時，將標籤放入 TreeNode 可編輯的狀態。 使用者完成編輯標籤之後，必須先再次按下 ALT+E 按鍵組合，才能再次編輯標籤。 此範例需要您在 上 Form 擁有 TreeView 。 樹狀檢視在其集合中 Nodes 也應該至少有一個 TreeNode 。

private:
   void treeView1_KeyDown( Object^ /*sender*/, KeyEventArgs^ e )
   {
      /* If the 'Alt' and 'E' keys are pressed,
         * allow the user to edit the TreeNode label. */
      if ( e->Alt && e->KeyCode == Keys::E )
      {
         treeView1->LabelEdit = true;
         
         // If there is a TreeNode under the mouse cursor, begin editing.
         TreeNode^ editNode = treeView1->GetNodeAt( treeView1->PointToClient( Control::MousePosition ) );
         if ( editNode != nullptr )
         {
            editNode->BeginEdit();
         }
      }
   }

   void treeView1_AfterLabelEdit( Object^ /*sender*/, NodeLabelEditEventArgs^ /*e*/ )
   {
      // Disable the ability to edit the TreeNode labels.
      treeView1->LabelEdit = false;
   }

private void treeView1_KeyDown(object sender, KeyEventArgs e)
{
   /* If the 'Alt' and 'E' keys are pressed,
      * allow the user to edit the TreeNode label. */
   if(e.Alt && e.KeyCode == Keys.E)
         
   {
      treeView1.LabelEdit = true;
      // If there is a TreeNode under the mouse cursor, begin editing. 
      TreeNode editNode = treeView1.GetNodeAt(
         treeView1.PointToClient(System.Windows.Forms.Control.MousePosition));
      if(editNode != null)
      { 
         editNode.BeginEdit();
      }
   }
}

private void treeView1_AfterLabelEdit(object sender, NodeLabelEditEventArgs e)
{
   // Disable the ability to edit the TreeNode labels.
   treeView1.LabelEdit = false;
}

Private Sub treeView1_KeyDown(sender As Object, _
  e As KeyEventArgs) Handles treeView1.KeyDown
   ' If the 'Alt' and 'E' keys are pressed,
   ' allow the user to edit the TreeNode label. 
   If e.Alt And e.KeyCode = Keys.E Then
      treeView1.LabelEdit = True
      ' If there is a TreeNode under the mouse cursor, begin editing. 
      Dim editNode As TreeNode = treeView1.GetNodeAt( _
        treeView1.PointToClient(System.Windows.Forms.Control.MousePosition))
      If (editNode IsNot Nothing) Then
         editNode.BeginEdit()
      End If
   End If
End Sub

Private Sub treeView1_AfterLabelEdit(sender As Object, _
  e As NodeLabelEditEventArgs) Handles treeView1.AfterLabelEdit
   ' Disable the ability to edit the TreeNode labels.
   treeView1.LabelEdit = False
End Sub

備註

屬性 MousePosition 會傳回 ， Point 表示參考屬性時滑鼠游標位置。 座標會指出畫面上的位置，而不是相對於控制項，而且不論游標是否位於控制項上，都會傳回。 畫面左上角的座標為 0，0。

屬性 MousePosition 與 Cursor.Position 屬性相同。
