martin Posted February 23, 2008 Share Posted February 23, 2008 If I set a label to have a cursor using GuiCtrlSetCursor then the first time a subclassed context menu appears its background is black. If you right click a second time to get the context menu redrawn then the background is changed to normal. Here is an example which is a copy of a post by Siao with 2 lines added. If you comment out the GuiSetCursor for the label then the problem goes. This problem was in a completely different script, and the context menu wasn't for an input, but this is about the simplest example I can make to show what I'm talking about. expandcollapse popup;post by Siao 11 Jan 2008 ;GuiRegisterMsg lets you work with messages of the main window. ;To work with messages of controls (such as in your case WM_PASTE to edit control), you need to subclass that control. #include <GUIConstants.au3> #Include <GuiEdit.au3> #include <windowsconstants.au3> $hGui = GUICreate("Type or paste some stuff",400,200,-1,-1,$WS_THICKFRAME,-1) $cInput = GUICtrlCreateInput("",20,20,360,20) $cInput2 = GUICtrlCreateInput("",20,50,360,20) #Region added lines to show problem with context menu $lab1 = GUICtrlCreateLabel("abcd",1,1,30,18) ;this Next line causes the problem With the context nenu background GUICtrlSetCursor (-1, 9); other values give same problem #EndRegion added lines to show problem $wProcNew = DllCallbackRegister("_MyWindowProc", "ptr", "hwnd;uint;long;ptr") $wProcOld = _WinSubclass(GUICtrlGetHandle($cInput), DllCallbackGetPtr($wProcNew)) _WinSubclass(GUICtrlGetHandle($cInput2), DllCallbackGetPtr($wProcNew)) ;_WinSubclass(GUICtrlGetHandle($cInput3), DllCallbackGetPtr($wProcNew)) and so on $DummyMenu = GUICtrlCreateDummy() $ContextMenu = GUICtrlCreateContextMenu($DummyMenu) $CommonMenuItem = GUICtrlCreateMenuItem("Common", $ContextMenu) $FileMenuItem = GUICtrlCreateMenuItem("File", $ContextMenu) GUICtrlCreateMenuItem("", $ContextMenu) $ExitMenuItem = GUICtrlCreateMenuItem("Exit", $ContextMenu) GUISetState(@SW_SHOW) While 1 Switch GUIGetMsg() Case $GUI_EVENT_CLOSE ExitLoop EndSwitch WEnd Func do_clever_stuff_with_clipboard($hWnd) $sData = ClipGet() If @error Then Return 0;clip data is not text or clip empty ;do whatever $sData = StringUpper($sData) ;set text GUICtrlSetData(_WinAPI_GetDlgCtrlID($hWnd), $sData);or _GUICtrlEdit_SetText($hWnd, $sData) Return 1 EndFunc ; Show a menu in a given GUI window which belongs to a given GUI ctrl Func ShowMenu($hWnd, $nContextID) Local $hMenu = GUICtrlGetHandle($nContextID) $arPos = MouseGetPos() Local $x = $arPos[0] Local $y = $arPos[1] DllCall("user32.dll", "int", "TrackPopupMenuEx", "hwnd", $hMenu, "int", 0, "int", $x, "int", $y, "hwnd", $hWnd, "ptr", 0) EndFunc Func _MyWindowProc($hWnd, $uiMsg, $wParam, $lParam) Switch $uiMsg Case $WM_PASTE Return do_clever_stuff_with_clipboard($hWnd) EndSwitch If $uiMsg = $WM_CONTEXTMENU And $hWnd = GUICtrlGetHandle($cInput)Then ;ConsoleWrite("cm" & @LF) ShowMenu($hGui, $ContextMenu) Return 0 EndIf ;pass the unhandled messages to default WindowProc Return _CallWindowProc($wProcOld, $hWnd, $uiMsg, $wParam, $lParam) EndFunc Func _CallWindowProc($lpPrevWndFunc, $hWnd, $Msg, $wParam, $lParam) Local $aRet = DllCall('user32.dll', 'int', 'CallWindowProc', 'ptr', $lpPrevWndFunc, 'hwnd', $hWnd, 'uint', $Msg, 'wparam', $wParam, 'lparam', $lParam) Return $aRet[0] EndFunc ;-- Wrapper for SetWindowLong API Func _WinSubclass($hWnd, $lpNewWindowProc) ;#define GWL_WNDPROC (-4) Local $aTmp, $sFunc = "SetWindowLongW" ;If @Unicode Then $sFunc &= "W" $aTmp = DllCall("user32.dll", "ptr", $sFunc, "hwnd", $hWnd, "int", -4, "ptr", $lpNewWindowProc) If @error Then Return SetError(1, 0, 0) If $aTmp[0] = 0 Then Return SetError(1, 0, 0) Return $aTmp[0] EndFunc ;==>_WinSubclass Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.

GaryFrost Posted February 23, 2008 Share Posted February 23, 2008 Looks good, but why re-write wrappers for SetWindowLong and TrackPopUPMenu? CallWindowProc looks like a good candidate to add to _WinAPI_xxxxx. expandcollapse popup;post by Siao 11 Jan 2008 ;GuiRegisterMsg lets you work with messages of the main window. ;To work with messages of controls (such as in your case WM_PASTE to edit control), you need to subclass that control. #include <GUIConstantsEx.au3> #Include <GuiEdit.au3> #include <windowsconstants.au3> #include <Constants.au3> #include <GuiMenu.au3> #include <WinAPI.au3> $hGui = GUICreate("Type or paste some stuff",400,200,-1,-1,$WS_THICKFRAME,-1) $cInput = GUICtrlCreateInput("",20,20,360,20) $cInput2 = GUICtrlCreateInput("",20,50,360,20) #Region added lines to show problem with context menu $lab1 = GUICtrlCreateLabel("abcd",1,1,30,18) ;this Next line causes the problem With the context nenu background GUICtrlSetCursor (-1, 9); other values give same problem #EndRegion added lines to show problem $wProcNew = DllCallbackRegister("_MyWindowProc", "ptr", "hwnd;uint;long;ptr") $wProcOld = _WinAPI_SetWindowLong(GUICtrlGetHandle($cInput), $GWL_WNDPROC, DllCallbackGetPtr($wProcNew)) _WinAPI_SetWindowLong(GUICtrlGetHandle($cInput2), $GWL_WNDPROC, DllCallbackGetPtr($wProcNew)) ;_WinAPI_SetWindowLong(GUICtrlGetHandle($cInput3), $GWL_WNDPROC, DllCallbackGetPtr($wProcNew)) and so on $DummyMenu = GUICtrlCreateDummy() $ContextMenu = GUICtrlCreateContextMenu($DummyMenu) $CommonMenuItem = GUICtrlCreateMenuItem("Common", $ContextMenu) $FileMenuItem = GUICtrlCreateMenuItem("File", $ContextMenu) GUICtrlCreateMenuItem("", $ContextMenu) $ExitMenuItem = GUICtrlCreateMenuItem("Exit", $ContextMenu) GUISetState(@SW_SHOW) While 1 Switch GUIGetMsg() Case $GUI_EVENT_CLOSE ExitLoop EndSwitch WEnd Func do_clever_stuff_with_clipboard($hWnd) $sData = ClipGet() If @error Then Return 0;clip data is not text or clip empty ;do whatever $sData = StringUpper($sData) ;set text GUICtrlSetData(_WinAPI_GetDlgCtrlID($hWnd), $sData);or _GUICtrlEdit_SetText($hWnd, $sData) Return 1 EndFunc ; Show a menu in a given GUI window which belongs to a given GUI ctrl Func ShowMenu($hWnd, $nContextID) Local $iSelected = _GUICtrlMenu_TrackPopupMenu(GUICtrlGetHandle($nContextID), $hWnd, -1, -1, -1, -1, 2) Switch $iSelected Case $CommonMenuItem ConsoleWrite("Common" & @LF) Case $FileMenuItem ConsoleWrite("File" & @LF) Case $ExitMenuItem ConsoleWrite("Exit" & @LF) EndSwitch EndFunc Func _MyWindowProc($hWnd, $uiMsg, $wParam, $lParam) Switch $uiMsg Case $WM_PASTE Return do_clever_stuff_with_clipboard($hWnd) Case $WM_CONTEXTMENU If $hWnd = GUICtrlGetHandle($cInput) Then ShowMenu($hGui, $ContextMenu) Return 0 EndIf Case $WM_SETCURSOR GUICtrlSetCursor(_WinAPI_GetDlgCtrlID($hWnd), 5);;set Ibeam cursor Return 1;;and don't let default windowproc mess things up EndSwitch ;pass the unhandled messages to default WindowProc Return _CallWindowProc($wProcOld, $hWnd, $uiMsg, $wParam, $lParam) EndFunc Func _CallWindowProc($lpPrevWndFunc, $hWnd, $Msg, $wParam, $lParam) Local $aRet = DllCall('user32.dll', 'int', 'CallWindowProc', 'ptr', $lpPrevWndFunc, 'hwnd', $hWnd, 'uint', $Msg, 'wparam', $wParam, 'lparam', $lParam) Return $aRet[0] EndFunc SciTE for AutoItDirections for Submitting Standard UDFs Don't argue with an idiot; people watching may not be able to tell the difference.
