Retrieving TreeView Items. Example

Applies to TestComplete 15.0, last modified on October 22, 2021

The following code demonstrates how you can work with TTreeView items (from the Borland VCL) from a TestComplete script using the methods and properties of the Win32TreeView object. This example assumes that the application displays a form with a TTreeView control on it. First, SaveItems retrieves all tree view items and saves them as text under the specified filename. Then, SaveItems compares this file with another one (the name is hard coded) and reports whether the tree view contents have changed directly to the test log.

To start testing, run the Main routine in TestComplete.

JavaScript

function Main()
{
  var p, w;

  p = Sys.Process("Project1");
  w = p.Window("TForm1", "Form1");
  SaveItems(w.Window("TTreeView", "TreeView1"), "C:\\Work\\Test1.txt");
}

function SaveItems(TV,FileName)
{
  Log.Message("TreeView Items:");
  aqFile.WriteToTextFile(FileName, "TreeView Items:" + "\r\n", aqFile.ctANSI, true);
  SaveChildItems(TV.wItems, 0, FileName);

  // Compares the generated file with the stored file
  if (! Files.Compare(FileName, "PreviousItems.txt"))
    Log.Error("TreeView has changed")
  else
    Log.Message("OK");
}

function SaveChildItems(ItemColl, Depth, FileName)
{
  var s, indent;

  for (let i=0; i<ItemColl.Count; i++)
  {
    // Forms an indent to denote subitems
    indent = "";
    for (let j=0; j<Depth; j++)
      indent += " ";
    // Obtains item caption
    s = indent + ItemColl.Item(i).Text;
    Log.Message(s);
    // Writes item caption to file
    aqFile.WriteToTextFile(FileName, s + "\r\n", aqFile.ctANSI);
    // Verifies whether the item has subitems and recursively calls the procedure on success
    if (!strictEqual(ItemColl.Item(i).Items, null))
      SaveChildItems(ItemColl.Item(i).Items, Depth+1, FileName)
  }
}

JScript

function Main()
{
  var p, w;

  p = Sys.Process("Project1");
  w = p.Window("TForm1", "Form1");
  SaveItems(w.Window("TTreeView", "TreeView1"), "C:\\Work\\Test1.txt");
}

function SaveItems(TV,FileName)
{
  Log.Message("TreeView Items:");
  aqFile.WriteToTextFile(FileName, "TreeView Items:" + "\r\n", aqFile.ctANSI, true);
  SaveChildItems(TV.wItems, 0, FileName);

  // Compares the generated file with the stored file
  if (! Files.Compare(FileName, "PreviousItems.txt"))
    Log.Error("TreeView has changed")
  else
    Log.Message("OK");
}

function SaveChildItems(ItemColl, Depth, FileName)
{
  var i, j, s, indent;

  for (i=0; i<ItemColl.Count; i++)
  {
    // Forms an indent to denote subitems
    indent = "";
    for (j=0; j<Depth; j++)
      indent += " ";
    // Obtains item caption
    s = indent + ItemColl.Item(i).Text;
    Log.Message(s);
    // Writes item caption to file
    aqFile.WriteToTextFile(FileName, s + "\r\n", aqFile.ctANSI);
    // Verifies whether the item has subitems and recursively calls the procedure on success
    if (ItemColl.Item(i).Items != null)
      SaveChildItems(ItemColl.Item(i).Items, Depth+1, FileName)
