child objects

hi all ,i would like to know more about child objects,am new for the QTP where it can be used.

Any of the object controls like a button, checkbox, radiobutton, combobox, frame etc of the application that can be referred only from its parent object are called child objects.

Eg.
A button may have been placed directly on a window. So, the window will be a parent object and the button will be a child object.

Eg.
A group of radiobuttons may have been placed under a frame and that frame is placed on a window. So, the window will be a parent object of the frame and the frame will be the parent object of the radiobuttons. Radiobuttons will be the child objects.

ChildObjects are used in real-time projects where we need to filter specific objects using descriptive programming, since there is a collection and we want to fetch the objects at runtime & get the value pertaining to business requirement.

e.g check that a webtable cell has value 3.

Set OD = Description.Create()
oD("micclass").value = "WebElement"
oD("html id").value = "oClai"

Set ODObject = Browser(b).Page(p).childObjects(OD)

While OD.getroproperty("innertext") <> "4"
if OD.getroproperty("innertext") = "3" then
''Logic on the elment
end loop
end if
