can we pass a variable with GUICtrlSetOnEvent?

[guwguw]

Is it possible to pass a variable with GUICtrlSetOnEvent?

I tried some "tricky" syntax, like

GUICtrlSetOnEvent(-1, "Slider1Change(" & $variable & ")")

but only got syntax error messages.

My intention: From a list of connections (which can be anywhere from 10 to 80), I try to give each a volume slider. I'm reading the list in a loop, creating the needed GUI code for each slider. In case some slider setting changed, I would like to pass that setting to some function, which saves the changed setting.

Here is a simplified, symbolic part of the code, reading related data from a database (but could be an INI file as well)

expandcollapse popup

Opt("GUIOnEventMode", 1)

$portList = GUICtrlCreateListView("    Port Name       |Prty|Owner|Balance|TrafficRate|", 160, 80, 699, 249, 0x0); BitOR($LVS_REPORT, $LVS_SINGLESEL, $LVS_SHOWSELALWAYS, $LVS_EX_FULLROWSELECT, $WS_HSCROLL, $WS_VSCROLL))

$list_of_ports = "All Ports|" 
$droplist_of_ports = "All Ports|" 

With $data
    $acounter = 0
    $row_val = 99
    While Not .EOF
        $acounter += 1
        $row_val += 14
        $list_of_ports = $list_of_ports & .Fields ("portname"  ).value & "|" 
        $droplist_of_ports = $droplist_of_ports & .Fields ("portname"  ).value & "|" 
; ... other assignments (left out for simplification)
        
;   MsgBox(0, 'ports now deals with', .Fields ("portname").value & "|  balance " & StringFormat ( "%5.2f", .Fields ("balance").value) &  @CRLF)
                       $thisone = .Fields ("portname"  ).value & "|" & .Fields ("priority"  ).value & "|" & StringFormat("%5.2f", .Fields ("balance"  ).value) & "|" & StringFormat("   %.2f", .Fields ("owner"  ).value) & "|" & StringFormat("     %.2f", .Fields ("trafficrate"  ).value))
        $CheckboxClickVar = "CheckboxClick" & $acounter
        $Checkbox1 = GUICtrlCreateCheckbox($CheckATbox, 124, 103 + ($acounter - 1) * 14, 16, 16); was $acounter - 1
        GUICtrlSetOnEvent(-1, "CheckboxClick")
        GUICtrlSetTip(-1, "Check to activate this port ID= " & .Fields ("acct_id"  ).value)
        $portlist_0 = GUICtrlCreateListViewItem($thisone, $portList)
; GUICtrlSetBkColor(-1,0x00ff00); Green

;---------->>>; this is the crucial part:
        $VolumeSlider1 = GUICtrlCreateSlider(860, $row_val, 129, 16, $GUI_SS_DEFAULT_SLIDER)
        GUICtrlSetOnEvent(-1, "portVolSlider1Change")
;---------->>>  ; end of crucial part
        GUICtrlSetLimit(-1, 100, 0)     
        GUICtrlSetData(-1, .Fields ("volume_level" ).value)
        GUICtrlSetTip(-1, "Set desired volume level for port " & .Fields ("portname" ).value & " (updates db directly)")

        .MoveNext
    WEnd
EndWith

Func portVolSlider1Change()
    $newVolume = GUICtrlRead($VolumeSlider1)
    MsgBox(0, "Volume Setting Changed to " & $newVolume & " in " & $acounter, "ID=" & @GUI_CtrlId & " WinHandle=" & @GUI_WinHandle & " CtrlHandle=" & @GUI_CtrlHandle, 2)

          ; here starts some updating procedure into database or INI file
; $ariskvar = _Query ($SQLconnect, "UPDATE `all_ports` SET volume_level = "& $newVolume &" WHERE 'acct_id' = " & $acct_id & ";")
          ;... 
EndFunc ;==>portVolSlider1Change

My question: Is there a way to inform Func portVolSlider1Change() of the affected portname or ID?

I know in a direct call, I could call the function with the variable, like in

portVolSlider1Change($identificationVariable)

... I hope it's not too confusing

@GUI_CtrlId, @GUI_CtrlHandle, @GUI_WinHandle

@GUI_CtrlId, @GUI_CtrlHandle, @GUI_WinHandle

If you speak english: Could you post some example showing how the GUICtrl stuff you are suggesting will pass a variable?

Handles and ID of the GUICtrl are known, but how would you pass the variable ($acct_id in this case) to the function portVolSlider1Change() ?

It's not so much that you pass the variable to the function, rather,

you check these macros once in the function, to find out which control was activated..

for $i = $first_control to $last_control
  if $i = @GUI_CtrlId then
    ; do stuff here
  endif
next

Thanks for your participation!

I think you might've given me an idea: since the amount of ports is not fixed, but dynamically changes, I would have to register the @GUI_CtrlId at setup time (when running the loop) and linking the proper $acct_id or $port_id to this @GUI_CtrlId - clumsy, but it'll work. I love working with arrays anyway, lol.

... unless we get another hint for passing the variable directly?

I'll run some tests and tell you (in case someone else has a similar need) how it worked.

To be honest, I didn't look at your code; I usually don't bother unless it's a complete listing and I can just chuck it into my test script; I simply noticed that you were having trouble understanding how to utilize AutoIt macros.

You probably want to check the AutoIt manual for GUICtrlRead() or ControlGetText();. used in conjunction with the macro, there's no need to build arrays, or set values, it's all automatic.

Remember, control ID's are just numbers; if the macro returns "23", then you can do stuff to/reteive stuff from that control, because you know its ID. Getting its text, "port ID", or whatever, should be trivial.

Here is the solution: At creation time

$VolumeSlider1 = GUICtrlCreateSlider(860, $row_val, 129, 16, $GUI_SS_DEFAULT_SLIDER)
        GUICtrlSetOnEvent(-1, "portVolSlider1Change")

the variable $VolumeSlider1 contains the ID, which then can be logged together with all the other program variables related to that port/account.
