OCRTable Object

Applies to TestComplete 15.42, last modified on August 01, 2022

Description

In TestComplete tests, you can use optical character recognition (OCR) to access tables rendered by a tested application, by their text contents. To do this, you can use any of the following:

The SearchArea can be an image or an onscreen object containing the area where the target table is located.

Both methods return the OCRTable object. Use the object and its properties to get the table data and to simulate user actions over the table. For information on the object’s properties, see the Members section below.

Example

JavaScript, JScript

function Main()
{
  // Navigate to the tested web page
  var url = "https://www.w3schools.com/html/tryit.asp?filename=tryhtml_table_border";
  Browsers.Item("chrome").Run(url);

  // Get the page area containing the table
  var page = Sys.Browser("chrome").Page("*");
  var gridArea = page.FindChild("idStr", "iframeresult", 10);

  if (gridArea != null)
  {
    // Specify whether the table has a header
    var hasHeader = true;
    // Specify the preferable search area
    var searchPref = spNone;
    // Recognize the table content
    var table = OCR.Recognize(gridArea).DetectTable(searchPref, hasHeader);

    // Call the routine that posts table data to the test log
    PrintTable(table);

  }
  else
    Log.Warning("Cannot obtain the search area.");
}

function PrintTable(aTable)
{
  if (aTable != null)
  {
    Log.AppendFolder("Table contents:");
    for (var i = 0; i < aTable.RowCount; i++)
    {
      for (var j = 0; j < aTable.ColumnCount; j++)
      {
        Log.Message(aTable.Cell(i, j).Text);
      }

  }
