I have taken luis' code, modified it slightly and added the necessary API functions for Linux and MacOS (both Carbon and Cocoa framework). Now this code example can be run in Windows, Linux and MacOS X . MacOS users with PB 5 using the default subsystem (Cocoa) should notice that wilbert's CocoaMessage userlib must have been installed before they can execute this code!

Code: Select all

EnableExplicit

CompilerIf #PB_Compiler_OS = #PB_OS_MacOS
  CompilerIf #PB_Compiler_Version < 500 Or (#PB_Compiler_Version >= 500 And Subsystem("Carbon"))
    ImportC ""
      GetControlProperty(ControlRef.L, PropertyCreator.L, PropertyTag.L, BufferSize.L, *ActualSize, *PropertyBuffer)
      TXNSetSelection(TXNObject.L, StartOffset.L, EndOffset.L)
      TXNShowSelection(TXNObject.L, ShowEnd.L)
    EndImport
  CompilerEndIf
CompilerEndIf

Procedure SelectEditorLine(EditorID.I, LineNumber.I)
  CompilerSelect #PB_Compiler_OS
    CompilerCase #PB_OS_Linux
      Protected EndOfLine.GtkTextIter
      Protected StartOfLine.GtkTextIter
      Protected *TextBuffer.GtkTextBuffer
      
      *TextBuffer = gtk_text_view_get_buffer_(GadgetID(EditorID))
      gtk_text_buffer_get_iter_at_line_(*TextBuffer, @StartOfLine, LineNumber)
      gtk_text_view_scroll_to_iter_(GadgetID(EditorID), StartOfLine, 0.0, #False, 0.0, 0.0)
      EndOfLine = StartOfLine
      gtk_text_iter_forward_to_line_end_(EndOfLine)
      gtk_text_buffer_select_range_(*TextBuffer, StartOfLine, EndOfLine)
    CompilerCase #PB_OS_MacOS
      CompilerIf #PB_Compiler_Version < 470 Or (#PB_Compiler_Version >= 500 And Subsystem("Carbon"))

        If GetControlProperty(GadgetID(EditorID), $50555245, $54584F42, 4, 0, @TXNObject) = 0
          StartOfLine = FindString(GetGadgetText(EditorID), GetGadgetItemText(EditorID, LineNumber)) - 1
          EndOfLine = StartOfLine + Len(GetGadgetItemText(EditorID, LineNumber))
          TXNSetSelection(TXNObject, StartOfLine, EndOfLine)
          TXNShowSelection(TXNObject, #True)

      CompilerElse
        Protected Range.NSRange
        
        Range\location = FindString(GetGadgetText(EditorID), GetGadgetItemText(EditorID, LineNumber)) - 1
        Range\length = Len(GetGadgetItemText(EditorID, LineNumber))
        CocoaMessage(0, GadgetID(EditorID), "setSelectedRange:@", @Range)
        CocoaMessage(0, GadgetID(EditorID), "scrollRangeToVisible:@", @Range)
      CompilerEndIf
    CompilerCase #PB_OS_Windows
      Protected Selection.CHARRANGE
      Protected StartOfLine.I
      
      StartOfLine = SendMessage_(GadgetID(EditorID), #EM_LINEINDEX, LineNumber, 0)
      Selection.CHARRANGE\cpMin = StartOfLine
      Selection.CHARRANGE\cpMax = StartOfLine + Len(GetGadgetItemText(EditorID, LineNumber)) + 1
      SendMessage_(GadgetID(EditorID), #EM_EXSETSEL, 0, @Selection)
  CompilerEndSelect
EndProcedure

Define i.I

OpenWindow(0, 270, 100, 200, 154, "Select line by line", #PB_Window_SystemMenu)
EditorGadget(0, 5, 5, 190, 144)

For i = 1 To 15
  AddGadgetItem(0, - 1, "Line number " + Trim(Str(i)))
Next

For i = 0 To CountGadgetItems(0) - 1
  SelectEditorLine(0, i)
  Delay(400)

  Repeat
    Select WindowEvent()
      Case 0
        Break
      Case #PB_Event_CloseWindow
        End
    EndSelect
  ForEver 
Next i

Repeat
Until WaitWindowEvent() = #PB_Event_CloseWindow

Update 1: Support for Mac OS X running with PB 5 and default subsystem Cocoa has been added.
Update 2: In the Linux part the code line

Code: Select all

gtk_text_view_scroll_to_iter_(GadgetID(EditorID), StartOfLine, 0.0, #False, 0.0, 0.0)

has been added to scroll a selected line which is currently hidden into the visible area. Furthermore for the sake of clarity I renamed the procedure from SetEditorState() to SelectEditorLine().
Update 3: The Mac part has been extended to also run with PB 4 or PB 5 with subsystem Carbon.

@Shardik
Even if i don't have linux, thanks for your code

@Ulix
Yes top cool the LUIS code

My dream ... that one day, reading the bible bill as it

@MachineCode
Simply because at this moment i'm alone ...

So, after the miracle, i'm so surprising to find myself the solution....

bad solution....but solution when even ..
The slightest thing was to thank me

But reassure you, every day, I insult me more often, than i congratulate myself

Haha, Kwaï, you're such a crazy guy!
I like you.

Thanks a lot

And me....and I love the people who like me

I sign you into my dance card ... I still have empty seats for the next dance

Thank you!

Travaillel perfectly!

For all the world!

I want to share this reflection! (If you feel that this reflection is relevant, I authorize you to copy this post and create a new topic with.

)

This is my reflection:

(The previous code) is the kind of feature that is lacking in native PureBasic!
Since it is possible with the API (Windows, Linux, MacOS), why Fred does not incorporate in PB?
(A meet him ... if he wants, no obligation!. It is a matter of rétorique!)

And waiting why not have a resource file ("xxxx.res") which would have added these commands for all OS?

Imagine commands like:

GetGadgetTextSelect (GadgetID, Start, End)
SetGadgetTextSelect (GadgetID, Start, End)
....

(A you list the commands you want, provided they can be made using API and all OS)

This resource file could be maintained by the community PureBasic, and would make available, functions that we lack (until Fred develops and integrates to PB).

And we would not have to reinvent the wheel.
We would not lose many hours of research.
We would not have to redo or test codes without end.
We would have these commands to work better!

If some do not know what code, the idea is there, and the whole community would benefit!

What do you think?

@ Shardik
Merci !

Travaillel parfaitement !

Pour tout les monde !

Je désire partager cette réflexion ! (Si vous jugez que cette réflexion est pertinente, je vous autorise à copier ce post et à en créer un nouveau topic avec.

)

Voilà ma reflexion :

(Le code prècedent) est le genre de fonction qui manque dans PureBasic en natif !
Puisque c'est possible avec les API (windows, linux, MacOS), pourquoi Fred ne les intègre pas dans PB ?
(A lui de répondre... si il le veut, pas obligé !. C'est une question de rétorique !)

Et attendant pourquoi ne pas avoir un fichier ressource ("xxxx.res") supplémentaire qui disposerait de ces commandes pour tous les OS ?

Imaginons des commandes comme :

GetGadgetTextSelect(GadgetID, Start, End)
SetGadgetTextSelect(GadgetID, Start, End)
....

(A vous de lister les commandes que vous désirez, pourvu qu'elles puissent être réalisées avec des API et sur tous les OS)

Ce fichier ressource pourrait être maintenu par la communauté PureBasic, et mettrait à disposition, des fonctions qui nous manquent (en attendant que Fred les développe et les intégre à PB).

Nous n'aurions ainsi pas a ré-inventer la roue.
Nous n'aurions pas à perdre de longues heures en recherche.
Nous n'aurions pas à faire ou refaire des codes de test à n'en plus finir.
Nous aurions ces commandes pour mieux travailler !

Si certains ne savent pas quoi coder, l'idée est là , et toute la communauté en profiterait!

Qu'en pensez-vous ?

A+
Ulix

Ps : @KCC

Yet an API that could be part of the additional controls (see my previous post)
