Custom Query

When there is a horizontal scrollbar in ListView, if this scrollbar is dragged to the right, then _GUICtrlListView_ClickItem() will often click outside the ListView area and not on the ListView Item. This wrong behavior will very often have the GUI lose focus. Reproducer :

#include <GuiListView.au3>
#include <GuiConstantsEx.au3>

$hGUI = GUICreate("Test", 500, 400)

$idListView = GUICtrlCreateListView("Col0|Col1|Col2|Col3|Col4|Col5|Col6|Col7|Col8|Col9", 10, 10, 480, 300)
For $i = 0 To 9
    _GUICtrlListView_SetColumnWidth($idListView, $i, 200)
Next
$idItem = GUICtrlCreateListViewItem("0|1|2|3|4|5|6|7|8|9", $idListview)

$idButton = GUICtrlCreateButton("Click me", 200, 340, 85, 25)

GUISetState()

While 1
	Switch GUIGetMsg()
		Case $GUI_EVENT_CLOSE
			ExitLoop

		Case $idButton ; click when scrollbar is on left (ok), then click with scrollbar on right => GUI goes to background :(
			_GUICtrlListView_ClickItem($idListView, 0)
	EndSwitch
WEnd

GUIDelete($hGui)

Does not happen with autoit-v3.3.15.0-beta-setup.exe, first occurred with autoit-v3.3.15.1-beta-setup.exe ​https://www.autoitscript.com/forum/topic/202668-autoit-v33151-beta

Checked release notes and guess it might be related to this fix:

• Fixed: Workarounds added to alleviate slow downs on Windows 10 1809 and later (OS bug/design change).

To test comment / un-comment the GUI_BKCOLOR_TRANSPARENT line and run with prod version and current Beta. With current Beta the updated data overwrites the label with erasing to old data first.

#include <GUIConstantsEx.au3>
Opt("GUIOnEventMode", 1)

GUICreate("Test", 550, 40)
GUISetOnEvent($GUI_EVENT_CLOSE, "_Exit")

$c_Label = GUICtrlCreateLabel(TimerInit, 10, 10, 430, 20)
GUICtrlSetBkColor(-1, $GUI_BKCOLOR_TRANSPARENT) ; comment / un-comment this line

GUICtrlCreateButton('Exit', 495, 10, 50)
GUICtrlSetOnEvent(-1, "_Exit")

GUISetState()

While 1
        GUICtrlSetData($c_Label, TimerInit())
WEnd

Func _Exit()
        Exit
EndFunc   ;==>_Exit

It should be reverted back to the actual 3.3.14.5 version :

Global Const $tagEDITSTREAM = "align 4;dword_ptr dwCookie;dword dwError;ptr pfnCallback"
