[Dev-C++] Edit_SetTabStops

[Lorenzo <co...@in...>]

I have problem with the message EM_SETTABSTOPS: if i set the tab character
size on message WM_CREATE all works, but if i try to set it in other place
in program it doesn't works.

Example:
OnCreate(HWND hwnd, CREATESTRUCT *lpCreateStruct)
{
    hwndEdit = CreateWindowEx(WS_EX_CLIENTEDGE, "EDIT", 0,
                            WS_CHILD | WS_VISIBLE | ES_AUTOHSCROLL |
ES_AUTOVSCROLL | ES_MULTILINE | ES_WANTRETURN,
                            rect.left, rect.top,
                            (rect.right - rect.left), (rect.bottom -
rect.top),
                            hwnd,
(HMENU)IDE_MAINEDIT,lpCreateStruct->hInstance, 0);

    FORWARD_WM_SETFONT(hwndEdit, (HFONT)GetStockObject(OEM_FIXED_FONT),
0,SendMessage);
    Edit_SetTabStops(hwndEdit, 1, &wTabSpacing);
}

This code works, but if i try to call Edit_SetTabStops in other functions
independently from wTabSpacing value the tab characters become huge, even if
i call SendMessage instead of Edit_SetTabStops macro: result doesn't change.
I have tried also to destroy the edit control and recreate it and  send
message EM_SETTABSTOPS, but it doesn't works.

Please help me.

I miss a declaration of wTabSpacing. Have you check if the problem
comes from this one?

Could you post the code of the function Edit_SetTabStops()?

Hope this helps.

WORD wTabSpacing;
Every value I give to wTabSpacing, the size of the tab becomes huge.

Edit_SetTabStops() is macro define in windowsx.h

In the API documentation it is a DWORD.

I don't really see the problem in the code apart of that one above. I
can only see a problem if you use a value larger than 1 as the second
parameter in the macro Edit_SetTabStops() because then you should use
an array of DWORDs.

I assume that you know this:
The EM_SETTABSTOPS message does not automatically redraw the edit
control window. If the application is changing the tab stops for text
already in the edit control, it should call the InvalidateRect function
to redraw the edit control window.

Hope this helps
