Detect and act upon mouse clicks?


Recommended Posts

Hello everyone!

My apologies if this is already covered in the API or in the forums, but I've been searching around for a couple of hours now without much success.

I want my application to act upon mouse clicks in certain windows. Ideally, I imagine something event-driven. I don't want to check if the mouse button is clicked in a loop since theoretically I could miss it if it's brief enough.

So in short: whenever the user clicks the mouse, I want to perform certain operations in my application. Furthermore, I want to know what window that has been clicked on.

Thanks in advance!

well, I can't give all the answers as I really haven't done a lot with mouse clicks, but this should get you started at least.

look at the WinAPI udfs in the help file, you can use some functions, such as _WinAPI_GetMousePos (),_WinAPI_GetWindowRect(), and _WinAPI_PtInRect() to help with getting the window that the mouse is in when clicked,

Maybe use _IsPressed() to detect clicks, not really sure on this one.

Hi guys

That mousehook is pretty slick but it runs the CPU at 15-20% whenever the mouse is moving. Still might be a good approach in some cases.

The register message only works when you click on the GUI window, not elsewhere, still might work.

The GUIGetCursorInfo($hov) is the solution I have used. With a 100 ms loop it gets most mouseclicks and runs the cpu at 0%. Change it to 50 ms and it gets every click but runs at 3-4% CPU.

Thank you for your replies!

I do need an effective (3-4% CPU load is close to the acceptable limit, might even be a little bit too high) solution that registers 100% of all clicks and works with non-AutoIt GUI's (which I assume GUIGetCursorInfo($hov) doesn't.)

Further suggestions are very welcome.

After I have checked the API I realized that GUIGetCursorInfo can't register the extra buttons or scroll events, all of which are necessary in order for my application to work. I'm sorry that I forgot to mention that.

Guess I need a more effective alternative of the low level mouse hook, then?

this is quick and dirty, and still has a high cpu percentage (15% avg), but with some refining you might be able to make it work better. It might not be exactly what you want either, but it works more or less.

#include <WinAPI.au3>
#include <Misc.au3>

$dll = DllOpen("user32.dll")

While 1
    $mouseclick1 = _IsPressed("01", $dll) ;left
    $mouseclick2 = _IsPressed("02", $dll) ;right
    $mouseclick3 = _IsPressed("04", $dll) ;middle
    $mouseclick4 = _IsPressed("05", $dll) ;x1
    $mouseclick5 = _IsPressed("06", $dll) ;x2
    If $mouseclick1 = TRUE OR $mouseclick2 = TRUE OR $mouseclick3 = TRUE OR $mouseclick4 = TRUE OR $mouseclick5 = TRUE Then
        Test()
    EndIf
    Sleep(10)
WEnd

DllClose($dll)

Func Test()
    $windows = _WinAPI_EnumWindowsTop ()
    $tPoint = _WinAPI_GetMousePos ()
    For $i = 1 To $windows[0][0]
        $tRect = _WinAPI_GetWindowRect ($windows[$i][0])
        If _WinAPI_PtInRect ($tRect, $tPoint) = True Then
            MsgBox(64, "", "Mouse Button was clicked in " & $windows[$i][0])
        EndIf
    Next
EndFunc

Okay. Played with the mouse hooking method a bit more and tweaked a script from this post written by authenticity

http://www.autoitscript.com/forum/index.ph...=GUIRegisterMsg

I think this is another viable solution for you.

The message boxes were messing me up so I wrote a hard exit (processclose)..... Press escape to get out.

#include <WinAPI.au3>

Dim Const $WM_NCXBUTTONDOWN  = 0x00AB
Dim Const $WM_NCXBUTTONUP      = 0x00AC
Dim Const $WM_NCXBUTTONDBLCLK   = 0x00AD
Dim Const $WM_MOUSEWHEEL        = 0x020A
Dim Const $WM_XBUTTONDOWN     = 0x020B
Dim Const $WM_XBUTTONUP   = 0x020C
Dim Const $WM_XBUTTONDBLCLK  = 0x020D
Dim Const $WM_MOUSELAST   = 0x020A
Dim Const $WM_LBUTTONDOWN = 0x0201
Dim Const $WM_RBUTTONDOWN = 0x0204
Dim Const $WM_MBUTTONDOWN = 0x0207 
 

Dim Const $tagMSLLHOOKSTRUCT = $tagPOINT&';dword mouseData;dword flags;dword time;ulong_ptr dwExtraInfo'

HotKeySet('{ESC}', '_EXIT')

$hFunc = DllCallbackRegister("Mouse_LL", "long", "int;wparam;lparam")
$pFunc = DllCallbackGetPtr($hFunc)
$hHook = _WinAPI_SetWindowsHookEx($WH_MOUSE_LL, $pFunc, _WinAPI_GetModuleHandle(0))

While 1
    sleep(100)
WEnd

Func _EXIT()
     _WinAPI_UnhookWindowsHookEx($hHook)
    DllCallbackFree($hFunc)
    ProcessClose("AutoIt3.exe")
EndFunc


Func Mouse_LL($iCode, $iwParam, $ilParam)
    Local $tMSLLHOOKSTRUCT = DllStructCreate($tagMSLLHOOKSTRUCT, $ilParam)
    
    If $iCode < 0 Then
        Return _WinAPI_CallNextHookEx($hHook, $iCode, $iwParam, $ilParam)
    EndIf
    
    If $iwParam = $WM_MOUSEWHEEL Then
        MsgBox(0,"","mousewheel")
    ElseIf $iwParam = $WM_LBUTTONDOWN Then
            MsgBox(0,"","left button")
        ElseIf $iwParam = $WM_RBUTTONDOWN Then
            MsgBox(0,"","Right button")
    EndIf
   
        
    Return _WinAPI_CallNextHookEx($hHook, $iCode, $iwParam, $ilParam)
EndFunc  ;==>_KeyProc

Hi

I might be missing some thing but here is a simple solution. The above quick and dirty solution finds all windows that

cover the mouse cursor. But if you only want the active window on top , just use the below code.

#include <WinAPI.au3>
#include <Misc.au3>


$dll = DllOpen("user32.dll")
HotKeySet("{ESC}", "Quit")
While 1
$mouseclick1 = _IsPressed("01", $dll) ;left
$mouseclick2 = _IsPressed("02", $dll) ;right
$mouseclick3 = _IsPressed("04", $dll) ;middle
$mouseclick4 = _IsPressed("05", $dll) ;x1
$mouseclick5 = _IsPressed("06", $dll) ;x2
If $mouseclick1 = TRUE OR $mouseclick2 = TRUE OR $mouseclick3 = TRUE OR $mouseclick4 = TRUE OR $mouseclick5 = TRUE Then
Test()
EndIf
Sleep(100)
WEnd

DllClose($dll)

Func Test()
$whnd = WinGetHandle("")
$sTitle = WinGetTitle($whnd)
$msg = "Mouse Button was clicked in " & $whnd & " active window title " & $sTitle
ConsoleWrite($msg & @CRLF)

;MsgBox(64, "", "Mouse Button was clicked in " & $whnd & " active window title " & $sTitle)
EndFunc



Func Quit()


Exit
EndFunc
