Hello
Recently i asked how can i localize PB apps.
There are some languages in the world the the writing position is not from Left-to-right like english and many other, there are some Right-to-left languages like my own, Hebrew and other like Arabic.

I found the solution which basicly makes a window OR a gadget localized.
What does it mean? it means:
- if a window is being modfied to be RTL language that all gadgets on the windows are being mirrored (not so important..)
- if a gadget is being modified to be RTL language then if it is a ListIconGadget the columns are being viewed in the oppsite way,
Its means that if you add the gadget "1" + chr(10) + "2" + chr(10)+"3"
you wont see 1 | 2 | 3
you will see 3 | 2 | 1

So far so good. You can see i posted in tricks and tips here
http://www.purebasic.fr/english/viewtopic.php?t=21840

But i have now a diffrent problem
It seems that the RTLGadget procedure i have in tricks and tips
Is might not be correct cause it works well on ListIconGadget , ListViewGadget but doesnt create a reguler border like a normal gadget creation, so i had to force a draw of a border like this:

Code: Select all

Procedure RTLgadget(GadgetNum.l,Switch.l,Border.l) 
  If Switch = 1 
    If Border = 1
      SetWindowLong_(GadgetID(GadgetNum),#GWL_EXSTYLE,#WS_EX_LAYOUTRTL | 0 | #WS_EX_CLIENTEDGE) 
    Else
      SetWindowLong_(GadgetID(GadgetNum),#GWL_EXSTYLE,#WS_EX_LAYOUTRTL | 0 ) 
    EndIf 
    SetWindowLong_(SendMessage_(GadgetID(GadgetNum),#LVM_GETHEADER,0, 0) ,#GWL_EXSTYLE,#WS_EX_LAYOUTRTL | 0)
  ElseIf Switch = 0 
    SetWindowLong_(GadgetID(GadgetNum),#GWL_EXSTYLE,#WS_EX_CLIENTEDGE) 
    SetWindowLong_(GadgetID(GadgetNum),#GWL_EXSTYLE,0) 
  EndIf 
EndProcedure

Now it is "OK" since there is a border but all other gadget like
StringGadget,EditorGadget are making a weird behavior!

thats why i said in the title Non-English, because the procedure automakes the gadget in the local language and when i write in my language (using Alt+shift to change cursor language) i get a weird space with the cursor and with Editorgadget i get nothing!

2nd Solution.

If you non-english users try to open any text box notepad.exe for example, and press the Right CTRL+ Right Shift
You will see that the gadget/notepad is auto being Right-To-Left (scrollbar changes it position to the leftside of the app/gadget)
the aligning is being changed.
So i tried this method to use SendKeys functions i found in the forums.
It seems it does work BUT ONLY to the last gadget?!?

Here is an Example which you can test the RTLGadget Procedure
And the SendKeys

Sorry PB 3.94 Code , i am doing a huge project with PB 3.94
So i delayed the move on PB4 later.

Code: Select all

Enumeration 
  #Window_Main 
  #Gadget_Editor 
  #Gadget_Editor1 
  #Gadget_Editor2 
  
EndEnumeration 
#WS_EX_LAYOUTRTL = 4194304
#LVM_GETHEADER = #LVM_FIRST + 31


Procedure SendKey(GadgetToShift.l)
  ActivateGadget(GadgetToShift) ; put focus on gadget
  ; Set Right Ctrl+Right Shift
  keybd_event_(#VK_RCONTROL,0,0 , 0); 
  keybd_event_(#VK_RSHIFT,0,0 , 0); 
  keybd_event_(#VK_RSHIFT,0, #KEYEVENTF_KEYUP,0); 
  keybd_event_(#VK_RCONTROL,0,#KEYEVENTF_KEYUP,0);
  Delay(10) 
  ;Set Alt+Shift
  keybd_event_(#VK_MENU,0,0 , 0);
  keybd_event_(#VK_SHIFT,0,0 , 0); 
  keybd_event_(#VK_SHIFT,0, #KEYEVENTF_KEYUP,0);
  keybd_event_(#VK_MENU,0,#KEYEVENTF_KEYUP,0); 
  
EndProcedure 

If OpenWindow(#Window_Main, 0, 0, 800, 800, #PB_Window_SystemMenu | #PB_Window_MinimizeGadget | #PB_Window_MaximizeGadget | #PB_Window_SizeGadget | #PB_Window_TitleBar | #PB_Window_ScreenCentered, "RTL test") 
  If CreateGadgetList(WindowID(#Window_Main)) 
    
    ;EditorGadget(#Gadget_Editor, 10, 10, 620, 460) 
    
    StringGadget(#Gadget_Editor, 10, 10, 620, 200,"",#PB_String_MultiLine|#WS_VSCROLL) 
    StringGadget(#Gadget_Editor1, 10, 210, 620, 200,"",#PB_String_MultiLine|#WS_VSCROLL) 
    StringGadget(#Gadget_Editor2, 10, 420, 620, 200,"",#PB_String_MultiLine|#WS_VSCROLL) 
  EndIf 
  
  ;RTLgadget(#Gadget_Editor,1,0) ; enable this with EditorGadget enabled to see how bad it looks
  
  ; sending the keys to make it local
  SendKey(#Gadget_Editor) 
  SendKey(#Gadget_Editor1)
  SendKey(#Gadget_Editor2)
  
  Quit = #False 
  Repeat 
    Select WaitWindowEvent() 
      Case #PB_Event_CloseWindow 
        Quit = #True 
    EndSelect 
  Until Quit 
EndIf 
End

in this code the sendkeys procedure i made takes effect only on the last gadget being changed all other return to default ?!?!

I am sorry for my bad english i cant explain myself good
but if you know windows API and see i might didnt put the correct values OR if you found a way to make this code works.

PLEASE HELP.

I apperciate your replies very much.

thank you.

Don´t set an extended window style without preserving the existing one. I don´t know if that really is the problem, but you can try.

Code: Select all

Procedure RTLgadget(GadgetNum.l, Switch.l) 
  If Switch = 1
    SetWindowLong_(GadgetID(GadgetNum), #GWL_EXSTYLE, GetWindowLong_(GadgetID(GadgetNum), #GWL_EXSTYLE) | #WS_EX_LAYOUTRTL) 
    SetWindowLong_(SendMessage_(GadgetID(GadgetNum), #LVM_GETHEADER, 0, 0), #GWL_EXSTYLE, GetWindowLong_(GadgetID(GadgetNum), #GWL_EXSTYLE) | #WS_EX_LAYOUTRTL)
  ElseIf Switch = 0 
    SetWindowLong_(GadgetID(GadgetNum), #GWL_EXSTYLE, GetWindowLong(GadgetID(GadgetNum), #GWL_EXSTYLE) & <binary> #WS_EX_LAYOUTRTL) 
  EndIf 
EndProcedure

Change <binary> into a tilde. (I'm at a mac with a weird keyboard and can't find it.)

And what did you expect to happen here? First you set the extended window style to someting, then you set it to 0. You could have dropped the first line and got the exact same functionality.
SetWindowLong_(GadgetID(GadgetNum),#GWL_EXSTYLE,#WS_EX_CLIENTEDGE)
SetWindowLong_(GadgetID(GadgetNum),#GWL_EXSTYLE,0)

Thanks
Thats why i said API cause i know i might have put the wrong values,
This solves me only the problem of the border that couldnt be shown before and i had to add the #WS_EX_CLIENTEDGE const.

But thats the only thing it solved.
