Title: CreateWindowW types
Post by: Andy on August 23, 2018, 05:44:28 am
Sorry, another one for you all.

I know I can use:

CreateWindowW

To create a static, button, edit control, but can I use it to create:

a combo box. and a listview?

If so, how do I populate them with data?

ADDSTRING surely won't work?

Sorry was just wondering.

Thanks,
Andy.

You will have to use winapi for this. I can make an example of a combo. The listview is rather more complicated, do you need the icon view with text and image or the detail view with several columns?

Fasecero,

Thanks for looking at this, I would just need the list view with several columns.

Any example you can provide would be great.

Thanks,
Andy.

Ok, here we go. I'm going to put everything together, maybe it's a bit too much at first but I think it's better that way. First an example of a combo

Code Select

$INCLUDE "windowssdk.inc"
$INCLUDE "Commctrl.inc"

CONST COMBO_1 = 1
INT subclassID = 12345
INT hwnd_combo = 0
WINDOW w1
OPENWINDOW w1,0,0,600,400,@MINBOX|@MAXBOX|@SIZE,NULL,"Simple Window",&w1_handler

' main loop
WAITUNTIL w1 = 0
END

' window procedure
SUB w1_handler
SELECT @MESSAGE
CASE @IDCREATE
CENTERWINDOW w1
OnInit()

CASE @IDCLOSEWINDOW
CLOSEWINDOW w1
OnFinish()
ENDSELECT
ENDSUB

SUB subclassProc(hWnd:INT,uMsg:INT,wParam:INT,lParam:INT,uIdSubclass:UINT_PTR,dwRefData:DWORD_PTR),INT
SELECT uMsg
CASE WM_COMMAND
SELECT LOWORD(wParam)
CASE COMBO_1
SELECT HIWORD(wParam)
CASE CBN_SELCHANGE ' the user has selected another index
OnIndexChange(lParam)
ENDSELECT
ENDSELECT

DEFAULT
RETURN DefSubclassProc(hWnd, uMsg, wParam, lParam)
ENDSELECT

RETURN 0
ENDSUB

SUB OnIndexChange(int handle) ' aux func
INT index = SendMessageW(handle, CB_GETCURSEL, 0, 0)
SETCAPTION w1, "Selected position: " + STR$(index + 1)
ENDSUB

SUB OnInit()
' subclass the window
SetWindowSubclass(w1.hwnd, &subclassProc, subclassID, 0)

' init common controls
_InitCommonControls()

' create the combo
INT dwStyles = CBS_DROPDOWNLIST | WS_CHILD | WS_OVERLAPPED | WS_VISIBLE
hwnd_combo = CreateCombo(w1.hwnd, 10, 10, 200, 100, COMBO_1, dwStyles)

' add some items
ComboAddString(hwnd_combo, L"First")
ComboAddString(hwnd_combo, L"Second")
ComboAddString(hwnd_combo, L"Third")

' select the second item
ComboSelectItem(hwnd_combo, 1) ' zero based index

' the first time you have to manually update the position yourself
OnIndexChange(hwnd_combo)
ENDSUB

SUB OnFinish()
RemoveWindowSubclass(w1.hwnd, &subclassProc, subclassID)
ENDSUB

And here's a minimal unicode listview, if there is anything you don't understand just ask.

Code Select

END

' window procedure

CASE @IDCREATE
CENTERWINDOW w1

ENDSELECT
ENDSUB

Thanks Fasecero,

You've put a lot into this post for me - appreciated!

Having a look at it now.

Thanks,
Andy.
