Detect if a button is clicked (non-Autoit GUI)

[MDCT]

Hello again, guys. As usual I'm stuck and in need of enlightenment.

This time, I need to detect if a user clicked a button from a specific non-Autoit GUI (a open/save dialog) and what button was clicked (save or cancel). Since it's non-AutoIt GUI, the GUIGetMsg() is not usable, right?

I tried to search and read somewhere about this:

Opt("WinTitleMatchMode", 4)
if ControlClick("[ClASS:#32770]", "", "[CLASS:Button; INSTANCE:2]") = 1 then ConsoleWrite("Button clicked." & @LF)

But the "if ControlClick" script always clicks the button, not detecting if the button is pressed or not.

Now, the only thing I can think off is to register mouse hook. Should I use DllCallbackRegister("_LLMouseProc", "long", "int;wparam;lparam") that will detect each mouse click and active window.... or is there better, more efficient method to achieve this?

Any help would be appreciated.

Thank you.

#include <GUIButton.au3> and use _GUICtrlButton_GetState() to get the state of the button using it's handle. If I'm not wrong, 610 is when the button is clicked.

Edit: 620...

You can use _IsPresssed(), but I think Hook would be preferable.

@Authenticity:

Yes, thank you, Authenticity. I think your idea (_GUICtrlButton_GetState) uses less CPU than using script that monitor mouse and window each time. I could get it to work. Strangely, it returns 108 as the state when a button is clicked... but, as long as it works, I'm happy.

@Yashied:

I would use _GUICtrlButton_GetState() instead the mousehook or if_pressed. With _GUICtrlButton_GetState(), I only monitoring a button, instead monitoring mouse and the active window. So, _GUICtrlButton_GetState() should use less CPU.

Both of you thank you for trying to help.

Take care.

Using _GUICtrlButton_GetState() you will most likely skip the event. You have to catch the release of a button rather than pressing it.

Look at WinControlSetEvent UDF.

In this case you can do something like this:

#include <WinControlSetEvent.au3>

HotKeySet("^q", "_Quit")

_WinControlSetEvent("[CLASS:#32770]", "Button2", "", "", "Clicked_Proc", "Button clicked.")

While 1
    Sleep(10)
WEnd

;Warning: blocking of this function by window messages with commands such as "Msgbox()" can lead to unexpected behavior,
;the return to the system should be as fast as possible !!!
Func Clicked_Proc($sParams, $hWnd, $nCtrlID)
    ConsoleWrite("Passed params: " & $sParams & @CRLF)
EndFunc

Func _Quit()
    Exit
EndFunc

Thanks for the info MrCreatoR. I tried _WinControlSetEvent but for some reason my double click is effected. I had to close the script to undo. I have added the _OnAutoItExit() inside the script, but it still won't unhook the mouse. I could prevent this by using second script, but I think it would take extra CPU usage.

So, I use _GUICtrlButton_GetState. This will only work on the confirmation dialog when we are going to save file that the name already exists.

#include <WinAPI.au3>
#include <GUIButton.au3>
#include <ButtonConstants.au3>

While 1
    Sleep(10)
    if _WinAPI_GetClassName(WinGetHandle("[ACTIVE]")) = "#32770" and StringInStr(WinGetText(WinGetHandle("[ACTIVE]")), "already exist") <> 0 then 
        Sleep(10)   
        local $hwndActive2 = WinGetHandle("[ACTIVE]"); Get active window
        ConsoleWrite("Dialog confirmation to replace file exists" & @CRLF)
        Sleep(1500)
        $buttonNo = ControlGetHandle("[ClASS:#32770]", "", "[CLASS:Button; INSTANCE:2]")
        
        while WinExists($hwndActive2)
            ConsoleWrite("No Button state is: " & _GUICtrlButton_GetState($buttonNo) & @CRLF)
            Sleep(40)
            If _GUICtrlButton_GetState($buttonNo) = 108 or _GUICtrlButton_GetState($buttonNo) = 620 Then     
                $save=0
                sleep(200)
            else
                $save=1 
            EndIf
            Sleep(10)
        WEnd
    
        ConsoleWrite("Save value is: " & $save & @CRLF)
    EndIf
    Sleep(10)
WEnd

I cannot just use If _GUICtrlButton_GetState($buttonNo) = 108 or 620 (note: on Scite the button state value is 108 if pressed, unlike notepad) to detect what the user selects. So, I use sleep(200) to wait for the dialog and check if the dialog exists or not. If after 200ms the button value is 108 or 620, the dialog doesn't exist... the script set the save value to 0, which means the user selects "No". It doesn't look smart, but it works for now.

Don't forget, to check the script you need to save a file that already exists, so the confirmation dialog appears.
