Hello, i have issues with my code If not WinSetTrans (line 44.45 - Both, red and yellow), Then not Show Childs (--- if Func _BK run on line 6, then does no matter if WinSetTrans, Childs not show !! if WinSetTrans (line 44.45 - Both, red and yellow) , Then Show Childs, why NEED WinSetTrans?? (--- if Func _BK run on line 6, then does no matter if WinSetTrans, Childs not show !! if WinSetTrans Child1(RED) ONLY, then Show Child1(RED) (--- if Func _BK run on line 6, then does no matter if WinSetTrans, Child not show !! if WinSetTrans (line 44 Child2(Yellow) ONLY), then Show Child1(RED) & Child2(Yellow), Why show Both ???? (--- if Func _BK run on line 6, then does no matter if WinSetTrans, Childs not show !! With $WS_POPUP (and $WS_EX_MDICHILD ) i have not above problems, but i need use $WS_CHILD Problems with $WS_POPUP : if change windows resolution (and restore next time), then childs change position on main form : i Need WinSetTrans on all GUIS when fade,with popup i need winsettrans all guis one by one : on minimize,restore Main GUI ,childs not following windows minimize/restore effect First i Create Child1, Second Child2, Why Child1 is above child2 ?

I'm trying to implement a scrolling list of controls. I have it sort of working using the GUIScrollBars_Ex UDF by @Melba23 found here. I also want to be able to tab through the controls, which I have accomplished by adding $WS_EX_CONTROLPARENT to the child GUI. The problem is that with that style applied, the scrollbar doesn't act like a scrollbar, instead it acts as a title bar to the child GUI letting you drag the it around (and you can even "maximize" it by double clicking). Any ideas? #include <GUIConstants.au3> #include "GUIScrollbars_Ex.au3" $iButtonCount = 30 $hParent = GUICreate('Example', 300, 230) $hChild = GUICreate('', 300, 200, 0, 0, BitOR($WS_CHILD, $WS_TABSTOP), $WS_EX_CONTROLPARENT, $hParent) For $i = 0 To $iButtonCount GUICtrlCreateButton('Button in list', 0, $i*30, 300, 30) Next GUISwitch($hParent) GUICtrlCreateButton('More Buttons', 0, 200, 150, 30) GUICtrlCreateButton('More Buttons', 150, 200, 150, 30) GUISetState(@SW_SHOW, $hParent) GUISetState(@SW_SHOW, $hChild) _GUIScrollbars_Generate($hChild, 100, $iButtonCount * 30+20) While GUIGetMsg() <> $GUI_EVENT_CLOSE WEnd

I don't often have occasion to use Child GUIs. I find the multitude of options confusing. The example below I made for my own purposes, to have a visual guide to what the various Style and Extended Style options lead to. Comments are much appreciated. This can be extended with many more examples and comments and why certain Styles are to preferred or avoided. Where certain types of Child GUIs are most suitable etc. The code is very basic. It is intended to show GUI Styles, not much else. ;~ ******************************************************************** ;~ Author: Skysnake ;~ ;~ Title: Demo various Child Gui options ;~ Updated: 2019.01.03 ;~ ;~ Function: A demo script, demonstrates various style & Extended ;~ style options for Child GUIs ;~ Comments, ideas and suggestions very welcome :) ;~ ;~ ******************************************************************** #include <WindowsConstants.au3> #include <GUIConstantsEx.au3> #include <ColorConstants.au3> #include <Constants.au3> #include <WinAPI.au3> #include <ButtonConstants.au3> #include <MsgBoxConstants.au3> ShowChildGuis() Func ShowChildGuis() Local $guiParent = GUICreate("The Parent GUI", 1200, 700, 0, 0) ;WHLT $idFilemenu = GUICtrlCreateMenu(" &Menu") $ButtonCancel = GUICtrlCreateButton("&Close", 0, 0, 80, 25) GUICtrlSetTip($ButtonCancel, "Click to close all") $ButtonShowChildGui = GUICtrlCreateButton("&Show", 0, 25, 80, 25) GUICtrlSetTip($ButtonShowChildGui, "Click to show a child GUI") ;~ #comments-start --- Toggle this and same code below to show context menu for parent or child Local $idContextmenu = GUICtrlCreateContextMenu() Local $idNewsubmenu = GUICtrlCreateMenu("This is a Context Menu", $idContextmenu) Local $idNewsubmenuText = GUICtrlCreateMenuItem("text", $idNewsubmenu) Local $idContextButton = GUICtrlCreateButton("Context", 0, 50, 80, 25) GUICtrlSetTip($idContextButton, "Right Click to see Context Menu") Local $idButtoncontext = GUICtrlCreateContextMenu($idContextButton) Local $idMenuAbout = GUICtrlCreateMenuItem("This is a Context Menu", $idButtoncontext) Local $idMenuOpen = GUICtrlCreateMenuItem("Open", $idContextmenu) Local $idMenuSave = GUICtrlCreateMenuItem("Save", $idContextmenu) GUICtrlCreateMenuItem("", $idContextmenu) ; separator Local $idMenuInfo = GUICtrlCreateMenuItem("Info", $idContextmenu) ;~ #comments-end --- Toggle this and same code below to show context menu for parent or child Local $DefaultChildGui = GUICreate("Default child gui", 300, 100, 300, 300, Default, Default, $guiParent) ;;;WHLT GUICtrlCreateLabel("Default attributes" & @CRLF & "Cannot move; cannot resize", 0, 0, 500, 200) GUICtrlSetBkColor(-1, $COLOR_aqua) $iStyle = _WinAPI_GetWindowLong(GUICtrlGetHandle($DefaultChildGui), $GWL_STYLE) $iExStyle = _WinAPI_GetWindowLong(GUICtrlGetHandle($DefaultChildGui), $GWL_EXSTYLE) GUISetStyle(BitOR($iStyle, $WS_VISIBLE), $iExStyle, $DefaultChildGui) Local $gChildGuiwithMenu = GUICreate("A child gui with menu", 300, 100, 50, 100, $WS_VISIBLE, BitOR($WS_EX_WINDOWEDGE, $WS_EX_MDICHILD, $WS_THICKFRAME), $guiParent) ;;;WHLT GUICtrlCreateLabel("Menu" & @CRLF & "Can move; cannot resize", 0, 0, 500, 200) GUICtrlSetBkColor(-1, $COLOR_skyblue) $idFilemenu = GUICtrlCreateMenu(" &File ") Local $idFileMenuItem = GUICtrlCreateMenuItem("An item for the File menu ", $idFilemenu) GUICtrlCreateMenuItem("", $idFilemenu) ; create a separator line ; use same dimensions for GUI and its Label Local $iSizeWide = 300, $iSizeHi = 100 GUICreate("A child gui", $iSizeWide, $iSizeHi, 100, 200, $WS_VISIBLE, BitOR($WS_EX_WINDOWEDGE, $WS_EX_TOPMOST, $WS_EX_MDICHILD, $WS_THICKFRAME), $guiParent) ;;;WHLT GUICtrlCreateLabel("Can move; cannot resize" & @CRLF & "Always on top", 0, 0, $iSizeWide, $iSizeHi) GUICtrlSetBkColor(-1, $COLOR_red) GUICreate("Child Gui Resizable", 300, 100, 200, 50, BitOR($WS_POPUP, $WS_SIZEBOX, $WS_CLIPCHILDREN, $WS_VISIBLE), $WS_EX_MDICHILD, $guiParent) ;;;WHLT GUICtrlCreateLabel("Popup Cannot move; can resize" & @CRLF & "Background", 0, 0, 500, 200) ; $WS_CHILD, GUICtrlSetBkColor(-1, $COLOR_blue) ; toggle the line below :) ;$idBackgroundmenu = GUICtrlCreateMenu(" &Menu ") ; give it a menu GUICreate("Child GUI, caption, resize", 300, 100, 300, 100, BitOR($WS_VISIBLE, $WS_POPUP, $WS_CAPTION), BitOR($WS_EX_TOOLWINDOW, $WS_EX_MDICHILD, $WS_EX_ACCEPTFILES), $guiParent) GUICtrlCreateLabel("Popup With Caption: Can move; cannot resize", 0, 0, 500, 200) GUICtrlSetBkColor(-1, $COLOR_yellow) GUICreate("Child GUI, abc", 300, 100, 400, 150, BitOR($WS_POPUP, $WS_VISIBLE, 0), $WS_EX_MDICHILD, $guiParent) GUICtrlCreateLabel("Popup Cannot move; cannot resize", 0, 0, 500, 200) GUICtrlSetBkColor(-1, $COLOR_green) ; Child GUI below has a control ............................. .............................................
