How AutoIt get a handle's control?

Recommended Posts

Luigi

Greetings, someone wold explain to me, how works or show me a algorithm about this concept?

You move your mouse in any direction and sometime it is over a control!

How this function, like GuiGetCursorInfo or another similar function works to get a handles control?

I thinking the AutoIt get the value from any WM_MESSAGE...

But, this is not the answer that I want...

Realy, I want undestand this... If is possible show any kind alghorithm, this is great!

Regards, Detefon.

If you don't want the way AutoIt does it, what exactly DO you want then? You are, after all, posting on the AutoIt forums looking for help.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.

@BrewManNH, thanks for your reply, what I would say is that I would like to further investigate this issue. 

I have idea / an impression that the answer is WMI, but I am not content with just that ... I want to go beyond just take the result of a ready function, I want to understand something more. 
Sorry for my English, I know it is bad, but even so, I do not give up. Sometime the google translator not say everthing.
 
My first ideia about how one would handle is captured by calculating their position relative to the mouse, something like if x's mouse >= x's control and x's mouse <= (x's control + width) and the same think to y axis, so you have a handle control! 
The idea, at first moment, it seems correctly, but, with many controls? I think not...
The next idea was: WMI! 
So I'm curious ... how does this happen?  :thumbsup:
 
@junkew, thank you, I read it.  :thumbsup:  :thumbsup:

Window­From­Point function uses WM_NC­HIT­TEST as a direction for you to google on.

and in AutoIT you could register those messages to be catched (read help on GUIRegisterMSG)

GUIRegisterMsg($WM_NCHITTEST, 
"WM_NCHITTEST")
 
Func WM_NCHITTEST($hWnd, $iMsg, $iwParam, 
$ilParam)    If ($hWnd = $hForm) And ($iMsg = $WM_NCHITTEST) Then 
Return $HTCAPTIONEndFunc   ;==>WM_NCHITTEST

I certainly doubt if you really want to understand but concepts like this can be studied in WINE (unless you have access to microsoft sources)
