Exemplos

O exemplo de código a seguir demonstra como manipular NodeMouseDoubleClick o evento e como usar o TreeNodeMouseClickEventArgs.The following code example demonstrates how to handle the NodeMouseDoubleClick event and how to use the TreeNodeMouseClickEventArgs. Para executar este exemplo, Cole o código em um formulário do Windows que contenha treeView1um TreeView nome.To run this example, paste the code into a Windows Form that contains a TreeView named treeView1. Preencha treeView1 com os nomes dos arquivos localizados c:\ no diretório do sistema em que o exemplo está sendo executado e associe o NodeMouseDoubleClick evento de treeView1 com o treeView1_NodeMouseDoubleClick método neste exemplo.Populate treeView1 with the names of files located in the c:\ directory of the system the sample is running on, and associate the NodeMouseDoubleClick event of treeView1 with the treeView1_NodeMouseDoubleClick method in this example.

    // If a node is double-clicked, open the file indicated by the TreeNode.

    void InitialTreeView_NodeMouseDoubleClick(Object^ sender,
        TreeNodeMouseClickEventArgs^ e)
