Description
Objects can have one or more children. For instance, processes are children of the Sys object, windows are children of processes, and so on. The ChildCount property of an object returns the number of its direct children. Use this property to iterate through the list of child objects.
Declaration
TestObj.ChildCount
Read-Only Property | Integer |
TestObj | A variable, parameter or expression that specifies a reference to one of the objects listed in the Applies To section |
Applies To
All processes, windows, controls and onscreen objects.
View Mode
To view this property in the Object Browser panel and in other panels and dialogs, activate the Advanced view mode.
Property Value
The number of child objects of the current object.
Remarks
The child objects list can change dynamically. In this case, you can use the Refresh
method of the tested object to update the actual list of its child objects.
Example
The following example demonstrates how to iterate through all child objects of an object. It iterates through the current active window's children in a loop and posts their names to the test log.
JavaScript, JScript
function GetWindowNames()
{
var w, i, wndChild;
w = Sys.Desktop.ActiveWindow();
Log.Message(w.Name, w.FullName);
// Add a for loop that iterates through child objects
for (i=0; i < w.ChildCount; i++)
{
wndChild = w.Child(i);
// Post the current child name to the test log
Log.Message(wndChild.Name, "", 0);
}
}
Python
def GetWindowNames():
w = Sys.Desktop.ActiveWindow()
Log.Message(w.Name, w.FullName)
# Add a for loop that iterates through child objects
for i in range ( 0 , w.ChildCount):
wndChild = w.Child(i)
# Post the current child name to the test log
Log.Message(wndChild.Name, "", 0)
VBScript
Sub GetWindowNames
Set w = Sys.Desktop.ActiveWindow
' Add a for loop that iterates through child objects
For i = 0 To w.ChildCount - 1
Set wndChild = w.Child(i)
' Post the current child name to the test log
Log.Message wndChild.Name
Next
End Sub
DelphiScript
procedure GetWindowNames;
var
i : integer;
w, wndChild : OleVariant;
begin
w := Sys.Desktop.ActiveWindow;
Log.Message(w.Name, w.FullName);
// Add a for loop that iterates through child objects
for i := 0 to (w.ChildCount - 1) do
begin
wndChild := w.Child(i);
// Post the current child name to the test log
Log.Message(wndChild.Name, '', 0);
end;
end;
C++Script, C#Script
function GetWindowNames()
{
var w, i, wndChild;
w = Sys["Desktop"]["ActiveWindow"]();
Log["Message"](w["Name"], w["FullName"]);
// Add a for loop that iterates through child objects
for (i=0; i < w["ChildCount"]; i++)
{
wndChild = w["Child"](i);
// Post the current child name to the test log
Log["Message"](wndChild["Name"], "", 0);
}
}
