Path Requester a simple way to control X Y?

[IdeasVacuum]

Is there a simple way to set the Path Requester's Window X and Y? It's quite a tall Window with long paths, so on a wide HD screen the bottom of the Window is off-screen. It's Y position is about 1/3 from the top of my screens. I know I could DIY the whole thing but if there is a lazy way.....

One way -> viewtopic.php?p=590402#p590402

You'll need to tweak it to support X and Y (and maybe W and H) parameters.

This code works with PathRequesters and MessageRequesters. Looking for the requester window by classname avoids problems with different system languages.

Here is one of the ways not to use any thread.
Using global variables instead of using the file map object will make it simpler.

Code: Select all

With few lines you can do everything with any Requester

Code: Select all

Global Hook,px,py,pw,ph

Procedure HookCB ( uMsg , wParam , lParam)   
   Select uMsg
     Case #HCBT_ACTIVATE
        SetDlgItemText_ (wParam, 1, "Option #1")
        SetDlgItemText_ (wParam, 2, "Option #2")
        SetDlgItemText_ (wParam, 14150, "Option #3")
        MoveWindow_(wParam,px,py,pw,ph,1)
        UnhookWindowsHookEx_(Hook) 
   EndSelect
   
   ProcedureReturn #False
EndProcedure

Hook = SetWindowsHookEx_ ( #WH_CBT, @ HookCB () , 0, GetCurrentThreadId_ ())

InitialPath$ = "C:\"
px = 100 :py = 100
pw = 400 :ph = 450
Path.s = PathRequester("Please choose your path", InitialPath$)
Debug Path

Thanks BarryG, Axolotl, breeze4me and Rashad.

I'm sure I'm not the only one that will find these solution very useful. I'm using Rashad's code as it is very concise.

Sure you're not the only one.
I have it for Open(Save)FileRequester but not for the path requester. So thanks

Code: Select all

If OpenWindow(1,40,40,0,0,"",#PB_Window_BorderLess)
  OpenFileRequester("Choose a file","","All files (*.*)|*.*",0)
  CloseWindow(1)
EndIf

Looking for the requester window by classname avoids problems with different system languages.

Yes but unfortunately it is not enough here on my windows 10 x64.
With FindWindow_("#32770", 0), it finds another window, hidden and with the same class

Code: Select all

Procedure EnumWindows(hwnd, lParam)
  Protected isOwned, winExStyle, title.s{1024}, class.s{64}
  
  isOwned = GetWindow_(hwnd, #GW_OWNER) 
  If isOwned = #Null
    winExStyle = GetWindowLong_(hwnd, #GWL_EXSTYLE)
    If (Not (winExStyle & #WS_EX_TOOLWINDOW)) Or (winExStyle & #WS_EX_APPWINDOW)
      If GetClassName_(hwnd, @class, 63)
        If class = "#32770"
          ;If IsWindowVisible_(hWnd) = lParam
            GetWindowText_(hwnd,@title,1024)
            Debug "WindowTitle: " + title + " - Class: " + class + " - Visible: " + IsWindowVisible_(hWnd)
          ;EndIf
        EndIf
      EndIf
     EndIf
  EndIf
  ProcedureReturn #True
EndProcedure

EnumWindows_(@EnumWindows(), #True)

==>
WindowTitle: The Event Manager Dashboard - Class: #32770 - Visible: 0
WindowTitle: Rechercher un dossier - Class: #32770 - Visible: 1

How to do it in this case with the 2 callbacks for EnumWindows and the thread ?

Or, else, how to find the Dll and the string identifier for "Browse for Folder", "Rechercher un dossier"

Code: Select all

Procedure.s LoadDllString(sDll.s, id)
  Protected hInstance, sReturn.s{261}, sExpand.s{261}
  ExpandEnvironmentStrings_(@sDll, @sExpand, 255)
  hInstance = LoadLibraryEx_(@sExpand, 0, #LOAD_LIBRARY_AS_DATAFILE)
  If hInstance
    LoadString_(hInstance, id, @sReturn, 256)
    FreeLibrary_(hInstance)
    ProcedureReturn sReturn
  EndIf
  ProcedureReturn ""
EndProcedure

Thanks @ChrisR for pointing that out ...

Sorry for sharing untested code.
I mainly use StringGadgets with this extension...

Code: Select all

 ; --- gathered together from different source files ---
CoInitialize_(#Null) ; for autocomplete in stringgadgets  
SHAutoComplete_(GadgetID(#GADGET_Main_StrDestDir), $50000021) ; #SHACF_AUTOAPPEND_FORCE_ON | #SHACF_AUTOSUGGEST_FORCE_ON | #SHACF_FILESYSTEM | #SHACF_FILESYS_DIRS 
CoUninitialize_()  ; autocomplete 

I found another solution.
