UPDATE: Scrollbar working as intended now! New buttons added. New code (uploaded + new zip file) ready for you to test. Optimizations and details like handling double clicking on controls are comming soon.

Noted, good advice! Now I understand why you needed WS_CLIPSIBLINGS

Yeah, and moving the cursor down or up so that the edit updates also changes the tumb position @Nine detected when the tumb was pressed in the main loop by ctrl id, and so did you, but that means an extra block of code, using _ispressed, and an extra fuction to update some variables, so i skipped that part ( not sure if that's a good approach but it's working 😛 ) Gonna put this and some other fixes in the MiniMark code soon. you helped me a lot, thanks for that!

@pixelsearch Found some time to make a simple example to wrap my head around the example you gave me I managed to boil it down to the code below for testing. Gonna skip resizing the tumb and double clicks for this test, do you see any flaws in the test scrollbar I made? The thing I did diffirently is how to handle the WM_COMMAND message to prevent it setting the tumb location twice while dragging the tumb: if $Scrolling then Return $GUI_RUNDEFMSG #include <GUIConstantsEx.au3> #include <GuiRichEdit.au3> #include <Misc.au3> #include <SendMessage.au3> #include <StaticConstants.au3> #include <WindowsConstants.au3> Local $s For $i = 1 To 100 $s &= 'Line ' & $i & @crlf Next AutoItSetOption('MouseCoordMode', 2) ; 2 = relative coords to the client area of the active window $Form = GUICreate('Form', 294, 432, 2034, 330) $Text = GUICtrlCreateLabel(0, 0, 0, 200, 17) $Edit = _GUICtrlRichEdit_Create($Form, $s, 120, 70, 100, 270, BitOR($es_multiline, $es_autovscroll, $es_nohidesel), 0) _GUICtrlRichEdit_SetScrollPos($Edit, 0, 0) $Bar = GUICtrlCreateLabel('', 70, 70, 40, 270, $SS_BLACKRECT) $Tumb = GUICtrlCreateLabel('', 70, 70, 40, 80, $SS_GRAYRECT) GUISetState(@SW_SHOW) ;----------------------------------------------- $BarX = 70 $BarY = 70 $BarWidth = 40 $BarHeight = 270 $TumbX = 70 $TumbY = 70 $TumbHeight = 80 $TumbMax = $BarY + $BarHeight - $TumbHeight $TumbPercent = 0 $EditHeight = 270 $LineFirst = 0 $LineLast = 0 $LineCount = 0 $LineVisible = 0 $LineTop = 0 $EditPercent = 0 $MouseY = 0 $Scrolling = False ;----------------------------------------------- func MouseOnTumb() local $MouseXY = MouseGetPos() Return $MouseXY[0] >= $BarX and $MouseXY[0] <= $BarX + $BarWidth and $MouseXY[1] >= $BarY and $MouseXY[1] <= $BarY + $BarHeight EndFunc GUIRegisterMsg($WM_COMMAND, WM_COMMAND) Func WM_COMMAND($hWnd, $iMsg, $wParam, $lParam) if $Scrolling then Return $GUI_RUNDEFMSG If $lParam = $Edit Then If BitShift($wParam, 16) = $EN_UPDATE Then UpdateTumbPosition() EndIf Return $GUI_RUNDEFMSG EndFunc Func UpdateTumbPosition() $LineFirst = _GUICtrlRichEdit_GetNumberOfFirstVisibleLine($Edit) $LineLast = _GUICtrlRichEdit_GetLineNumberFromCharPos($Edit, _GUICtrlRichEdit_GetCharPosFromXY($Edit, 1, $EditHeight)) $LineCount = _GUICtrlRichEdit_GetLineCount($Edit) $LinesVisible = $LineLast - $LineFirst + 1 ; count last visible line too (+1) $MaxScroll = $LineCount - $LinesVisible If $MaxScroll <= 0 Then $EditPercent = 0 Else $EditPercent = ($LineFirst - 1) / $MaxScroll EndIf GUICtrlSetData($text, $EditPercent) $TumbY = $BarY + $EditPercent * ($BarHeight - $TumbHeight) GUICtrlSetPos($Tumb, $TumbX, $TumbY) EndFunc Func UpdateEditPosition() $MouseY = MouseGetPos(1) $TumbY = $MouseY - $TumbHeight / 2 If $TumbY < $BarY Then $TumbY = $BarY If $TumbY > $TumbMax Then $TumbY = $TumbMax GUICtrlSetPos($Tumb, $TumbX, $TumbY) $TumbPercent = ($TumbY - $BarY) / ($TumbMax - $BarY) GUICtrlSetData($Text, $TumbPercent) $LineFirst = _GUICtrlRichEdit_GetNumberOfFirstVisibleLine($Edit) $LineLast = _GUICtrlRichEdit_GetLineNumberFromCharPos($Edit, _GUICtrlRichEdit_GetCharPosFromXY($Edit, 1, $EditHeight)) $LineCount = _GUICtrlRichEdit_GetLineCount($Edit) $LinesVisible = $LineLast - $LineFirst $LineTop = $TumbPercent * ($LineCount - $LinesVisible) + 1 _GUICtrlRichEdit_ScrollLines($Edit, $LineTop - $LineFirst) EndFunc ;----------------------------------------------- While 1 Switch GUIGetMsg() Case $GUI_EVENT_CLOSE _GUICtrlRichEdit_Destroy($Edit) GUIDelete($Form) Exit Case $gui_event_primarydown if MouseOnTumb() then $Scrolling = True Case $gui_event_mousemove if $Scrolling then UpdateEditPosition() Case $gui_event_primaryup $Scrolling = False EndSwitch WEnd

Little update: Work in progress

Pixelsearch, I will have a look at it soon, looks promising thanks for this!

yep.. but I don't understand the code of Nine very well, and I only want to implement the scrollbar part (and like to know what i'm doing instead of accidentally creating memory leaks), feel free to help if you wanna add such scrollbar and/or understand Nine's code From what I understand from it, it uses a lot of DllCallbackRegisters, DllCallbackGetPtrs, and api calls like "_WinAPI_SetWindowSubclass", a bit of Chinese to me

New BETA version 4 uploaded as ZIP-file! see shortcuts section in code for the new ones installer and stable release coming soon!

Update, you can now save some settings to an ini file search function done code is better organized UPLOAD HAPPENING SOON Screenshot: Issues: New bug detected for saving and loading zoom settings for the edit control:

Update, The code is getting a huge update, that's why it takes a little longer for me to post the new version. I also found a solution for the scrollbar that finds the balance between simplicty and performance, it now updates how it should and works a little diffirently. Implementing your own scrollbar is not the most easy task I learned, but a lot of people have showed me inspiring code and examples. Updates coming soon: • better search gui in same style and functions • better gui design with stylized popup messages • no 100 images anymore, but just a few with the text on them being generated on the fly • final touches on the graphics • save as function added I also wanna thank Nine for giving me some new insight in the more low level functions of autoit, and everyone in this topic for all the idea's and effort: Please have a look at Nine's UDF, it's very cool! Also the windows "dark mode" one Regards!

Understood thanks anyways! So far I had this unfinished draft: Global $hScrollProc Func CreateCustomScrollbar() $hScrollProc = DllCallbackRegister(ScrollBarProc, 'lresult', 'hwnd;uint;wparam;lparam;uint_ptr;dword_ptr') _WinAPI_SetWindowSubclass(GUICtrlGetHandle($minimark_thumblabel), DllCallbackGetPtr($hScrollProc), 0, 0) EndFunc Func ScrollBarProc($hWnd, $iMsg, $wParam, $lParam, $iID, $iData) If $iMsg <> $WM_LBUTTONDOWN Then Return _WinAPI_DefSubclassProc($hWnd, $iMsg, $wParam, $lParam) Local $iYStart = MouseGetPos(1) Local $aEditPos = ControlGetPos("[ACTIVE]", "", $minimark_edit) Local $iScrollRange = _GUICtrlEdit_GetLineCount($minimark_edit) While _IsPressed("01") Local $iYCurrent = MouseGetPos(1) If $iYStart <> $iYCurrent Then Local $iNewPos = ($iYCurrent - $aEditPos[1]) * 100 / $iScrollRange _GUICtrlEdit_Scroll($minimark_edit, $iNewPos) EndIf WEnd Return _WinAPI_DefSubclassProc($hWnd, $iMsg, $wParam, $lParam) EndFunc But I have a lot to learn when it comes to the low level magic in your code, your UDF is fasinating

Hi Nine, Would it be to much to ask to show us a trimmed down version / function just to make a label behave like a thumb, like in this example? I tried to do it myself, but i'm afraid i'm messing up inportant calls and create memory leaks ... What I understand about your code is that it makes use of _WinAPI_SetWindowSubclass to hook the RichEdit control to handle custom scrollbar behavior? $hProc is a callback function (RichEditProc), which processes scroll messages right? Local $hProc = DllCallbackRegister(__RGUI_ScrollBarProc, 'lresult', 'hwnd;uint;wparam;lparam;uint_ptr;dword_ptr') _WinAPI_SetWindowSubclass(GUICtrlGetHandle($idScroll), DllCallbackGetPtr($hProc), $idScroll, $idCtrl) Local $aScroll = [$fCall, $hProc, $iTop + 5, $iSize - 54] $mScroll[$idScroll] = $aScroll Return $idScroll This is like chinese to me. Noob asking for help here, I know (no pressure tho).

Dude...! This would be perfect! Tomorrow i'm gonna have a look at your udf, thanks for posting!

ok, thanks for letting me know

This is the best solution so far, i'll think i'm gonna stick with this one I'll have to extract out of the udf only what is needed, but the original udf gets credits (if that's an ok way to burrow code on this forum)
