Getting Header Items' Images in Desktop Windows Applications

Applies to TestComplete 15.47, last modified on January 20, 2023

While testing header controls, you can use specific properties and methods of the corresponding program object to perform certain actions and obtain data stored in controls. You can call these methods and properties from your keyword tests, as well as from scripts. This topic describes how to work with the needed properties and methods from your scripts. However, when testing a control from your keyword test, you can use the same methods and properties calling them from keyword test operations. For more information, see Keyword Tests Basic Operations.

When working with header controls, you may need to obtain images that are displayed within header items. You can use a set of specific properties and methods of the Win32Header object for this purpose. Each header item can display either a string or a bitmap. You can obtain an item's bitmap via the wBitmap property. Header items can also display an additional image, which is taken from the image list along with the string or bitmap. You can obtain the additional image of a header item using the wImage property.

Both properties return the Picture object that corresponds to the specified images. If the specified item does not have an image, wBitmap (or wImage) returns an empty object (null in JavaScript, JScript, C#Script and C++Script, None in Python, Nothing in VBScript, nil in DelphiScript).

TestComplete provides a set of specific methods that allow you to process images. For example, you can use the Log.Picture method to post images to the test log, save them to a file using the Picture.SaveToFile method, determine the size of an image via the Picture.Size property, and so on. See the Picture object description to get information on the available actions. The following sample code obtains the images that are associated with header items and posts them to the test log.

When working with header items, you may need to check whether the specified item has an image or a bitmap. You can perform this check as it is described in the example above, but there is one more approach that is based on using the Win32HeaderItemFormat object. You can obtain this object via the wFormat property of the Win32Header object. Win32HeaderItemFormat provides the following properties to work with header items’ images:

  • HasImage - Returns True if the specified item has an additional image.
  • IsBitmap - Returns True if the specified item displays a bitmap.
  • IsBitmapOnRight - Returns True if the bitmap is displayed to the right of the header item's text.

The following sample code demonstrates how you can use the above-mentioned properties of the Win32HeaderItemFormat object. It checks whether the second item has images and posts informative messages to the test log:

  w = p.Window("CabinetWClass", "SYSTEM (C:)", 1).Window("SHELLDLL_DefView", "", 1).Window("DUIViewWndClassName", "", 1).Window("DirectUIHWND", "", 1).Window("CtrlNotifySink", "", 1).Window("SysListView32", "FolderView", 1);
  w.Keys("[Apps]");
  w.PopupMenu.Click("View|Details");
  Header = w.Window("SysHeader32", "", 1);
  
  // Check whether the second item has assigned images
  ItemFormat = Header.wFormat(1);
  if (ItemFormat.HasImage == false)
      Log.Message("There is no additional image")
    else Log.Message("The " + Header.wItem(1) + "item has an image")
  if (ItemFormat.IsBitmap == true)
  {
    if (ItemFormat.IsBitmapOnRight == true)
        Log.Message("The bitmap is to the right of the text")
     else 
        Log.Message("The bitmap is to the left of the text")
  }
    else Log.Message("There is no bitmap")
}
