Hotkey long press/double tap detection

Recommended Posts

guner7

Hi everyone,

I would like to share a simple snippet where I use for my hotkey script.

I was searching for a solution whereby pressing a same key, I could have different outcome according to the way the key is being pressed.

1) Double tap/press fast (like double click the mouse) - outcome A

2) Long press or HOLD for awhile (2-4 sec) - outcome B

#Include <Timers.au3>

Global $interval_timer, $counter
HotKeySet("{F10}", "_terminate")



While 1
    Sleep(10)
WEnd



Func _terminate() 
    Local $itv_timer
    $itv_timer = _Timer_Diff($interval_timer)
    $interval_timer = _Timer_Init()
    ;ConsoleWrite($itv_timer & @CRLF) ;to review the timer difference so I can decide the range to capture double tap sequence
    If $itv_timer > 100 And $itv_timer < 250 Then
        $counter = 0
        $interval_timer = _Timer_Init()
        MsgBox("","","double tap detected")
    Elseif $counter >= 25 Then      
        $counter = 0
        $interval_timer = _Timer_Init()
        MsgBox("","","long press detected")
    ElseIf $itv_timer < 50 Then 
        $counter = $counter + 1
        ConsoleWrite($counter & @CRLF)
    Else
        $counter = 0
    EndIf
EndFunc

The trick here is to collect and use the frequency of the hotkey is called, and the time difference between each time the hotkey is being called.

My coding style is not efficient and can be such a mess most of the time, any suggestion or better coding are welcome.

I hope you find this one helpful.:)

Have you seen _Timer_GetIdleTime( )??

MM also I think you can set the sleep in your loop way higher since hotkey is an event..

I like doing away with the extra dependency on timer.au3 better

HotKeySet("{F10}", "_terminate")

While 1
    Sleep(100000)
WEnd

Func _terminate()
    Local Static $itv_timer = 0
    Local Static $counter = 0
    Local $itv_diff = TimerInit() - $itv_timer
    ;ConsoleWrite($itv_diff & @CRLF) ;to review the timer difference so I can decide the range to capture double tap sequence

    If $counter >= 25 Then
        $counter = 0
        MsgBox("", "", "long press detected")
    ElseIf $itv_diff < 1000000 Then
        $counter += 1
        ConsoleWrite($counter & @CRLF)
    ElseIf $itv_diff < 5000000 Then
        $counter = 0
        MsgBox("", "", "double tap detected")
    Else
        $counter = 0
    EndIf
    $itv_timer = TimerInit()
EndFunc

Hi Bilgus,

I never aware of _Timer_GetIdleTime() before this..

Suppose they can be replace with TimerInit() and TimerDiff() without timer.au3.

However your code give me an error as following:

(8) : ==> No variable given for "Dim", "Local", "Global", "Struct" or "Const" statement.:
Local Static $itv_timer = 0
Local ^ ERROR

Any fix?

try this at the top of script 

#Region ;**** Directives created by AutoIt3Wrapper_GUI ****
#AutoIt3Wrapper_Au3Check_Parameters=-q -d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6 -w 7
#EndRegion ;**** Directives created by AutoIt3Wrapper_GUI ****

 

I repasted the code but It runs fine on my PC

maybe try changing names or barring that remove the static keyword and paste the variable at the top of script as Global

      Hi Guis,
       
      I need to create keyboard shortcut to navigate the tabs and activate them, but I could not use the code below:

      Hello everyone,
      I am trying to setup a GUI accelerator to close the utility as soon as esc is pressed.  It works fine with hotkey but I want to make sure that the utility only exits if its window was active when esc was pressed. My utility has 2 buttons, Backup and Restore.
      The exit function checks if the button clicked was Backup or Restore and then displays an error message accordingly.
      If pressed backup, $button = 1
      if pressed restore, $button = 2
      the value of $button is set inside backup() or restore() functions
      Opt("GUIOnEventMode", 1) Opt("GUICoordMode", 1) $Form1 = GUICreate("Form1", 419, 124, 238, 194, $WS_DLGFRAME) $B_backup = GUICtrlCreateButton("Backup", 48, 40, 145, 41) $B_restore = GUICtrlCreateButton("Restore", 224, 40, 145, 41) ;================ > HotKeySet('{ESC}', "terminate") GUICtrlSetOnEvent($B_backup, "Backup") GUICtrlSetOnEvent($B_restore, "Restore") GUISetState(@SW_SHOW) Dim $accelKey[1][2] = [["{ESC}", terminate()]] GUISetAccelerators($accelKey) While 1     Switch GUIGetMsg()         Case $GUI_EVENT_CLOSE             Exit     EndSwitch WEnd  
      Exit function:
      func terminate() Do     $msg = GUIGetMsg() Until $msg <> 0 While 1         If $button = 1 Then             ProcessClose("robocopy.exe")             MsgBox(16, "Abort!", "Backup Aborted!")             exit         ElseIf $button = 2 Then             ProcessClose("robocopy.exe")             MsgBox(16, "Abort!", "Restore Aborted!")             exit         Else             While 1                 For $i = 3 To 1 Step -1                     SplashTextOn("Closing Utility...", $i, 130, 54, -1, -1, 0, "Calibri", "", 900)                     Sleep(1000)                 Next                 ExitLoop             WEnd             SplashOff()             Exit Endif WEnd What am I doing wrong here? The utility closes as soon as it launches with Splash text.

      Hi All,
      Could someone please PLEASE tell me what I'm doing wrong here?
      I feel like I'm close to figuring this out, I think I've identified what is causing the issue.
      Whenever I try to use the hotkey CTRL+SHIFT+T (or any other letter other than T for that matter) to paste the text to notepad, my CTRL and SHIFT keys are held down *IF* I release them *WHILE* the raw text is being written.
      It seems to be that if I release the CTRL+SHIFT keys:
      Before the Send Raw text starts to write to the screen: the CTRL and SHIFT keys ARE NOT held down, this is good During the Send Raw text being written to the screen: the CTRL and SHIFT keys ARE held down perpetually until I physically press them on the keyboard, this is bad After the Send Raw text has written all text to the screen: the CTRL and SHIFT keys ARE NOT held down, this is good This is also the case if I were to use the Windows Key as the hot key instead of the CTRL+SHIFT, I would need to tap the WIN key physically on my keyboard if I released it while the raw tet was being sent to the screen (eg, WIN+T).
      This issue also happens no matter which program I try to write the text to.
      Here's some example code:
      (I've put a bunch of "a's" in there to give enough time to test releasing the CTRL+SHIFT before/during/after the writing of them)
      HotKeySet("^+t", "WriteTxt") Func WriteTxt() WinWaitActive("Untitled - Notepad") $var = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" send($var, 1) EndFunc While 1 Sleep(500) WEnd Thanks guys!

      So currently I have some code waiting for a status to change(there is different indicators to check if this status has changed) 
      Func oneRow($count) $globaltimer = _Timer_SetTimer($gui, 60000*10, "reset") $errTimer = TimerInit() While (1)         If PixelGetColor(1117, 326) = 0xC6C6C6 Then ExitLoop (1)         Sleep(500)         MouseClick("right")         Sleep(600)         If PixelGetColor(1117, 326) = 0xC6C6C6 Then ExitLoop (1)         If TimerDiff($errTimer) > 5000 Then             If PixelGetColor(1100, 310) = 0x707070 Or PixelGetColor(901, 305) = 0xE0E0E0 Or PixelGetColor(1043, 383) = 0xC6C6C6 Then                 Sleep(100)                 Send("{esc}")                 Sleep(1000)             EndIf         EndIf     WEnd .... EndFunc   ;==>oneRow The two timers is for error checking. This works just fine the problem comes when I go into the while 1 loop, my hotkeys at the top of the program seems to stop working, for an example 
      HotKeySet("{f1}", "stop") Func stop() Exit EndFunc ;==>stop Does not work at all after the while loop. The globaltimer is never called even though i tried setting the delay all the way down to 3 seconds. So I thought that maybe one of the function I use is blocking so the timer would never be called/the hotkey wouldn't work? if i make an delay just before the while loop the hotkey works just fine. Oh and the errTimer is supossed to not reset after 5 seconds but should keep making the check it does if five seconds have passed
