Gradually hide GUI on the left of the screen

This is a code I wrote to gradually show/hide a GUI on the left of the screen:

#include <GUIConstantsEx.au3>

#include <WindowsConstants.au3>

    ;WinSetOnTop($hGUI, "", 1)

    GUISetState(@SW_SHOW, $hGUI)

    While 1
        If $iToMove = 1 Then
            __GUIGraduallyHide($hGUI)

Click ON/OFF button to enable/disable the feature. When enabled, the GUI gradually moves away on the left when mouse is not hover it and appears again on mouse hover.

I wrote an improved version of the code, that now correctly works on all screen sides (auto-detecting the nearest side and the taskbar position):

Hey,

Thanks for sharing but missing file WinAPIsysinfoConstants.au3 :(

Update to the latest version of AutoIt.


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.

I updated the code in the second post... after several tests and improvements:

- it correctly manages taskbar on any side

- it works with both window on top or not

- it may works much better also with multiple monitors
