This control already present on Windows.
You need to use CreateWindow API with the class name of "SysTreeView32".

I have a rather terse example in my controls usage examples. I realize the syntax is fairly advanced - using the features of fasm2; but I am happy to help with any understanding.

Edit: Just realized you are working in 32-bit -- perhaps it is not a good example, for you.

this kind of treeview should be in fasmw.
really.
and interactive because fasm is very fast and real. just a single band (with scrollbar) pointing to where the current file is and i will be very very happy.

but of course, it should be platform independent. like, wind, linux... hem, not fasml? ok, then, fasmw shoul dbe ported to debian, and so on...

and be sure, '4' will never happen in this suite, never!

The tree in FASM IDE would be great!
I am coding the x64 FASM IDE now for x64 development.
I wanted the tree, but then I need to update a tree when I type code into editor.
Say, I am creating a structure in code --- the tree would need a constant update, like inserting/removing data members, functions, etc.
Keeping files in a tree is nice, but you can just list files easily in a dialog.
Or, maybe update the tree by some "Refresh" button.
Or with a timer.
A lot of code for just fancy Visual Studio effect.
I have "Go To Definition" feature and I can search for occurences of an item in all files or in an active file.
However, seeing code at a glance would be nice.
Like, click on a file in tree and select "Expand All" --- showing all procedures, structures, labels in the file.

Then it would be necessary to make an automatic substitution. {Ctrl+Space -> Popup}

Yes i think it would be nice.

Personally, I can't work without such a feature (tree), and at the same time with several open windows and split editor view. That's why I've been using Notepad++ consistently for many years for my simple programming needs in ASM/C/BASIC.

Sorry for being off topic, zvn.

Glad to serve you)

When I tried to add a tree-view control to the form, I found that in the "comctl32.inc" file, in the "Common control window classes" section, some class names differ from those used in the Microsoft manuals, for example, the tree-view element is called "TREEVIEW_CLASS", while in the manuals it is "WC_TREEVIEW".
Who is important, what is the reason for changing the class names?

Help me understand why adding an element to the tree-view in the code below does not work. I am sure that the error is in filling the TV_ITEM structure, since the elements are added, but for some reason they are empty.

Code:

format    PE GUI
include   'win32w.inc'
entry     beg

section '.code' code executable
beg:

        invoke GetModuleHandle, 0
        invoke DialogBoxParam, eax, 0, HWND_DESKTOP, DialogProc, 0
        invoke ExitProcess, 0

proc    DialogProc hwnddlg, msg, wParam, lParam
xor     eax, eax
cmp     [msg], WM_CLOSE
je      FreeDialog
cmp     [msg], WM_COMMAND
jne     ExitProc
mov eax, BN_CLICKED
shl eax, 16
add eax, 10
cmp eax, [wParam]

        mov     [tvi.mask], TVIF_TEXT
        mov     [tvi.hItem], 0
        mov     [tvi.state], 0
        mov     [tvi.stateMask], 0
        mov     [tvi.pszText], _testTree
        mov     [tvi.cchTextMax], 6
        mov     [tvi.iImage], 0
        mov     [tvi.iSelectedImage], 0
        mov     [tvi.cChildren], 0
        mov     [tvi.lParam], 0

        mov     [tvins.hParent], TVI_ROOT
        mov     [tvins.hInsertAfter], TVI_FIRST
        mov     [tvins.item], dword tvi

        invoke  SendDlgItemMessage, [hwnddlg], 1, TVM_INSERTITEM, 0, tvins
        ret
FreeDialog:
invoke  EndDialog, [hwnddlg], 0

ExitProc:
xor     eax, eax
ret
endp

section '.data' data readable writeable
tvi             TV_ITEM
tvins           TV_INSERTSTRUCT
_testTree       du      'abc',0

section 'import' import readable

  library kernel,         'kernel32.dll',\
          user,           'user32.dll'

  import kernel,\
      GetModuleHandle,    'GetModuleHandleW',\
      ExitProcess,        'ExitProcess'


  import user,\
      DialogBoxParam,     'DialogBoxParamW',\
      EndDialog,          'EndDialog',\
      SetDlgItemText,     'SetDlgItemTextW',\
      SendDlgItemMessage, 'SendDlgItemMessageW',\
      MessageBox,         'MessageBoxW',\
      LoadMenu,           'LoadMenuW',\
      SetMenu,            'SetMenu',\
      GetDlgItem,       'GetDlgItem'

section '.rsrc' resource readable

directory       RT_DIALOG, dialogs

resource        dialogs, 0, LANG_NEUTRAL, MainWindow

dialog          MainWindow, 'MainDLG', 700, 300, 100, 100, WS_VISIBLE+WS_CAPTION+WS_SYSMENU
dialogitem      WC_TREEVIEW, '', 1, 10, 10, 50, 50, WS_VISIBLE+WS_BORDER
dialogitem      'button', 'add', 2, 10, 70, 20, 20, WS_VISIBLE
enddialog

Oh yeah, if you run this code, don't forget to change the class name in the resources: WC_TREEVIEW to TREEVIEW_CLASS!

The name of the constant is not important within the source code. You can freely rename her whatever you want. But the value of the constant cannot be changed. Otherwise, you will not be understood.

You can set cchTextMax to 0, the parameter will be ignored. For Unicode characters you must use TVM_INSERTITEMW instead of TVM_INSERTITEM

fasmw 1.73 error: undefined WC_TREEVIEW
dialogitem WC_TREEVIEW, '', 1, 10, 10, 50, 50, WS_VISIBLE+WS_BORDER

What is value for WC_TREEVIEW ?

I found: WC_TREEVIEW equ "SysTreeView32"
nice variant:

Code:

WC_TREEVIEW equ "SysTreeView32" 
dialogitem WC_TREEVIEW,'',1,10,10,50,50, WS_VISIBLE+WS_BORDER+TVS_LINESATROOT+TVS_HASLINES

To get rid of the error, you must either change TREEVIEW_CLASS to WC_TREEVIEW in the "comctl32.inc" file, or use TREEVIEW_CLASS in the resources, or a pointer to the string "SysTreeView32"

I try get text from treeview But not get any text.
tv TV_ITEM
mov [tv.pszText],mybuffer
mov [tv.cchTextMax],20

And do SendMessage

I done this !

Code:

tvi             TV_ITEM
mov [tvi.mask],TVIF_TEXT
mov [tvi.cchTextMax], 50 ;maximum name size bytes
mov [tvi.pszText],textBuffer


invoke GetDlgItem,[hwnddlg],1

push eax
invoke SendMessage,eax,TVM_GETNEXTITEM,TVGN_FIRSTVISIBLE, 0
mov [tvi.hItem],eax
pop eax
invoke SendMessage,eax,TVM_GETITEMA, 0, tvi

invoke MessageBox,0,textBuffer,0,0

We need do loop(for all names) and do TVM_GETNEXTITEM & TVGN_NEXTVISIBLE to jump next name.
Then we get all names from treeView

Hello friends!
I am writing a MW_NOTIFY message handler for the TVN_SELCHANGED notification of the Tree-view control in the dialog window procedure.
I encountered a problem getting the value of the hdr.code parameter of the NM_TREEVIEW structure.
The description states that the TVN_SELCHANGED notification passes the address of the NM_TREEVIEW structure in the lParam parameter, which includes the MHDR structure.
In fact, the lParam parameter contains the stack address, which in turn points to another address, using which with an offset of 8 (equal to the value of NM_TREEVIEW.hdr.code) I get an access violation error.
How can I access a member of the structure whose address is passed in the lParam parameter?
Maybe someone has encountered this problem?
Maybe there is some solution?
