Scrollbars Made Easy - New version 27 Jan 22

[Norm73]

Hello Melba23,

thank you for your reply. Please don’t worry about the timing — your health comes first. I really appreciate that you are even considering looking into the issue.

I wish you all the best for your treatment and a smooth recovery.

Hello Melba23,

just a quick update: I was able to solve the issue myself, thanks to the hint in this post:
https://www.autoitscript.com/forum/topic/198673-_guiscrollbars-question/#findComment-1425538
The solution works well, although it requires a small additional helper function in the base script.
I tried integrating it directly into your UDF, but I couldn’t get it to work there.
If you ever find a way to incorporate this cleanly into the UDF, I’d really appreciate it — it would
certainly help others who might run into the same problem.

Norm73,

Love it - managed to solve the problem without having to do anything! I will certainly look into incorporating the solution into the UDF in the future.

Norm73,

Please try this Beta version: 

I am fairly confident that it will work, but please do try to break it!

GUIScrollbars_Ex_Mod_Max.au3

I tested the file, and it actually works flawlessly. It can definitely be used as it is.
However, when comparing both approaches, I noticed that the variant with the helper function in the base script feels more refined overall.
In that version, both the window content and the ScrollBox positions remain stable even when the window is resized.
Additionally, you don’t need to scroll back to the desired position after changing the window size.
One thing I noticed in the beta version is that the known effect reappears when the window is resized by dragging its edges with the mouse instead of using the [–] [ ] [x] buttons to maximize or minimize it.

Norm73,

Thanks for the testing - glad it seems to have partially resolved the [rob;lems you were having

Try adding the _GUIScrollbars_ReSizer function to your script after generating the scrollbars - that is designed to get the scrollbars correctly adjusted when using resizable GUIs. However, you may still find that the scrollbars return to the top left position as it was too complicated (at least for this coder) to get them to be in exactly the same place for every possible case.

Yes, I added the _GUIScrollbars_ReSizer function as you suggested, and now everything works exactly as it should.
Thank you very much for your help!

Hello @Melba23 I just tried to use your example.

just modified a little:

expandcollapse popup

#include <GUIConstantsEx.au3>
#include <GuiListView.au3>

#include "GUIScrollbars_Ex.au3"

$hGUI = GUICreate("Test", 500, 500)
GUISetBkColor(0xFFCCCC)

$cButton_1 = GUICtrlCreateButton("Recreate LV", 10, 450, 80, 30)

GUISetState()

$hAperture = GUICreate("", 400, 400, 50, 10, $WS_POPUP, $WS_EX_MDICHILD, $hGUI)
GUISetBkColor(0xCCFFCC)

$cLV = _CreateLV(10, 10)

_GUIScrollbars_Generate($hAperture, 920, 0, 0, 0, False, 0, True)

GUISetState()

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $cButton_1
            ; Get current horizontal scroll position
            $iPos = _GUIScrollBars_GetScrollPos($hAperture, $SB_HORZ)
            ; Move to full left scroll
            _GUIScrollBars_SetScrollInfoPos($hAperture, $SB_HORZ, 0)
            Sleep(1000) ; These Sleep lines are just to slow the process for visualisation, they are not otherwise required
            ; Delete ListView
            GUICtrlDelete($cLV)
            Sleep(1000)
            ; Recreate ListView
            _CreateLV(50, 50)
            Sleep(1000)
            ; Scroll back to previous position
            _GUIScrollBars_SetScrollInfoPos($hAperture, $SB_HORZ, $iPos)
    EndSwitch

WEnd


Func _CreateLV($iX, $iY)

    $cListView = GUICtrlCreateListView("", $iX, $iY, 900, 300)
    GUICtrlSetBkColor($cListView, 0xCCCCFF)
    For $i = 0 To 8
        _GUICtrlListView_AddColumn($cListView, "Column " & $i, 100)
    Next

    Return $cListView

EndFunc   ;==>_CreateLV

I have 2 questions.

Is there a way to use Horizontal scroll a the top of the $hAperture gui.

and

Is there a way to set different color fo the scroll bar ?
maybe with WM_CTLCOLORSCROLLBAR ?

For example, I was thinking about creating an additional window with zero height or a height suitable for displaying a ScrollBar.
This additional window could be displayed above the ListView window, or generally above the ListView, so the ListView could remain in the main GUI.

Then somehow combine the scrolling of this additional window (maybe in WM_NOTIFY) with the moving of the invisible scrollbar for the Listview.

mLipok,

No idea about either of your questions - both of which, IMO, fall outside the scope of this UDF.
