例

次のコード例では、サイズNodeFontを指定したサイズに変更し、ツリー ノードの親TreeViewコントロールを調整ItemHeightします。 この例では、 Form オブジェクトの TreeView コレクション TreeNode を含むコントロールを含むコントロールと、フォント サイズを含むコントロール ComboBox が必要です。

private:
   void Button1_Click( Object^ /*sender*/, EventArgs^ /*e*/ )
   {
      myTreeView->ItemHeight = 5;
      myTreeView->SelectedNode->NodeFont = gcnew System::Drawing::Font( "Arial",5 );
      
      // Get the font size from combobox.
      String^ selectedString = myComboBox->SelectedItem->ToString();
      int myNodeFontSize = Int32::Parse( selectedString );
      
      // Set the font of root node.
      myTreeView->SelectedNode->NodeFont = gcnew System::Drawing::Font( "Arial",(float)myNodeFontSize );
      for ( int i = 0; i < myTreeView->Nodes[ 0 ]->Nodes->Count; i++ )
      {
         
         // Set the font of child nodes.
         myTreeView->Nodes[ 0 ]->Nodes[ i ]->NodeFont = gcnew System::Drawing::Font( "Arial",(float)myNodeFontSize );

      }
      
      // Get the bounds of the tree node.
      Rectangle myRectangle = myTreeView->SelectedNode->Bounds;
      int myNodeHeight = myRectangle.Height;
      if ( myNodeHeight < myNodeFontSize )
      {
         myNodeHeight = myNodeFontSize;
      }

      myTreeView->ItemHeight = myNodeHeight + 4;
   }

private void Button1_Click(object sender,EventArgs e)
{
   myTreeView.ItemHeight = 5;
   myTreeView.SelectedNode.NodeFont = new Font("Arial",5);

   // Get the font size from combobox.
   string selectedString = myComboBox.SelectedItem.ToString();
   int myNodeFontSize = Int32.Parse(selectedString);

   // Set the font of root node.
   myTreeView.SelectedNode.NodeFont = new Font("Arial",myNodeFontSize);
   for(int i = 0; i < myTreeView.Nodes[0].Nodes.Count; i++)
   {
      // Set the font of child nodes.
      myTreeView.Nodes[0].Nodes[i].NodeFont =
        new Font("Arial",myNodeFontSize);
   }

   // Get the bounds of the tree node.
   Rectangle myRectangle = myTreeView.SelectedNode.Bounds;
   int myNodeHeight = myRectangle.Height;
   if(myNodeHeight < myNodeFontSize)
   {
      myNodeHeight = myNodeFontSize;
   }
   myTreeView.ItemHeight = myNodeHeight + 4;
}

Private Sub Button1_Click(sender As Object, e As EventArgs)
   myTreeView.ItemHeight = 5
   myTreeView.SelectedNode.NodeFont = New Font("Arial", 5)

   ' Get the font size from combobox.
   Dim selectedString As String = myComboBox.SelectedItem.ToString()
   Dim myNodeFontSize As Integer = Int32.Parse(selectedString)

   ' Set the font of root node.
   myTreeView.SelectedNode.NodeFont = New Font("Arial", myNodeFontSize)
   Dim i As Integer
   For  i = 0 To (myTreeView.Nodes(0).Nodes.Count) - 1
      ' Set the font of child nodes.
      myTreeView.Nodes(0).Nodes(i).NodeFont = New Font("Arial", _
        myNodeFontSize)
   Next i

   ' Get the bounds of the tree node.
   Dim myRectangle As Rectangle = myTreeView.SelectedNode.Bounds
   Dim myNodeHeight As Integer = myRectangle.Height
   If myNodeHeight < myNodeFontSize Then
      myNodeHeight = myNodeFontSize
   End If
   myTreeView.ItemHeight = myNodeHeight + 4
End Sub
