detect mouse touch-click on Browser

[frank10]

I tried both _ispressed and the MouseOnEvent UDF: both work on desktop or other windows clicks such as Scite or Thunderbird, but they fail with Browsers such as Edge or Chrome.

For example, this with _Ispressed:

#include "misc.au3"

While 1
    If  _IsPressed(01) Then _OnSingleClick()
WEnd

Func _OnSingleClick()
    Do
        sleep(1)
    Until not _IsPressed(01)

    ConsoleWrite("pressed" & @CRLF)
EndFunc

when you (EDIT touch-)click on Chrome, nothing happens.

How to solve?

This works for me.

#include <Misc.au3>

$hDLL = DllOpen("user32.dll")

While 1
    If  _IsPressed("01", $hDLL) Then _OnSingleClick()
    Sleep(1)
WEnd
DLLClose($hDLL)

Func _OnSingleClick()
    Do
        sleep(1)
    Until not _IsPressed("01", $hDLL)

    ConsoleWrite("pressed" & @CRLF)
EndFunc

Edit: I forgot to close $hDLL.

Thank you CYCho, but it doesn't work well.

EDIT

If I touch-click on Chrome it does nothing. And also, if I single touch-click on Scite it does nothing, instead it works in Scite only if I double touch-click.

Before, with my code above, on Scite it gets also the single touch-click on Scite...

EDIT2:

it is the Sleep(1) on While cycle: you must delete this if you want to get a single touch-click on Scite!

 

BTW

I'm using a Surface Pro 7 (w10 64bit)

I'm using Windows 10 64bit desktop and it works fine. Maybe touch-click on Surface Pro has different key value. Please check if _IsPressed("01", $hDLL) returns True when you touch-click on Surface Pro.

Yes, it returns "True" also on Touch.

[CYCho]

I tested with my laptop and it works as expected. I'm sorry I can't help you with Surface Pro.

Edit: My laptop is not a touch screen. I tested the code on touch pad.

I tested also on a Lenovo Yoga 720 with touchscreen: It's the same.

You may want to consider this approach, as it is more robust and in line with Microsoft Windows:

Ok Nine,

so if I do:

$hGUI = WinGetHandle("Chrome")

    DllCall("User32.dll", "BOOL", "RegisterTouchWindow", "HWND", $hGUI, "ULONG", 2)

;~     GUIRegisterMsg($WM_TOUCH, "WM_TOUCH")

How do I register the msg to the Chrome Window, instead of the classic GUIRegisterMsg for the GUI window?

[Nine]

Have you tested the return value ?  Is it working or not ? I don't know if you can register a window that you do not own. You will have to experiment with it.

I can't test it, I don't have a touch screen monitor here.

[frank10]

With the GUI Handle, the dllCall returns this array:

[0] = 1

[1]= 0x001102DC

[2]= 2

Trying to connect to Scite Handle Window, the dllCall returns this array:

[0] = 0

[1]= 0x000F02DC

[2]= 2

and @error = 0 on both call.

 

So, yes DLLcall seems to be working having the array as a result, but the function  RegisterTouchWindow returns 0 with  a non-GUI win.

In fact: " The function fails with ERROR_ACCESS_DENIED if the calling thread does not own the specified window. "

 

So, if I can't associate to a window, how can I detect touch-clicks on browsers?
