Find classes

[hiepkhachsg]

Hi all, i want to find a top level of displaying control class at a point in the window, how can i do it? Any body can give me some advices or suggestions. Thanks in advance.

@hiepkhachsg you need to be a bit more specific in your request. If you want to find control and class names you would use the Window Info Tool located in the same directory where you installed AutoIt. How about a detailed example of the window, and what information you're trying to get - help us help you

I mean that a function (not W.I.T.) to find a class at a point in the window. I can find what classes have area containing that point but, when it have many layer classes (more than 2 classes) at that point, i don't know what class is the top level layer of displaying (it mean this class will take effect when you click or press a key).

?

#include <WinAPI.au3>

HotKeySet("{ESC}", "_exit") 
Global $g_tStruct = DllStructCreate($tagPOINT) 

While 1
    DllStructSetData($g_tStruct, "x", MouseGetPos(0))
    DllStructSetData($g_tStruct, "y", MouseGetPos(1))
    ToolTip(_WinAPI_GetClassName(_WinAPI_WindowFromPoint($g_tStruct)))
    Sleep(100)
WEnd

Func _exit()
    Exit
EndFunc

Thank mikell. I known that, but it use for a window (or point) is displayed on screen. I want to find in window which is hidden behind the others. I stuck when there are many class layers at a point, how to know what class is on top?

See faq 31 refernces to iuiautomation where you can see in example 1 some ui treewalkers.

Thank junkew, i've seen your example but it do not solve my problem, you may misunderstand my matter. For example, at a point in the window (of a program) i found 3 classes, with 3 classes containing that point i want to know what a class is on top of displaying !?

Treewalker normally can handle that if you check the boundaries of each traversed window in the three. Simplespy will learn you the windowfrompoint function to give you the class on top. Studying sources from WINE for windowfrompoint will teach you how travrrsing tree work.
