Multiple lines Tooltiptext?

[Eddy Van Esch]

Hi all,
Maybe a simple question: How can I create a tooltiptext that consists of multiple
lines? I tried in the example below with a simple $CR (carriage return) but this does
not work. $CRLF also does not work..
Kind regards
Eddy

   #COMPILE EXE
   OPTION EXPLICIT
   #INCLUDE "win32api.inc"
   #INCLUDE "CommCtrl.Inc"

  GLOBAL ti AS TOOLINFO
  GLOBAL hDlg AS LONG
  GLOBAL hWnd_ToolTip AS LONG

  DECLARE SUB SetToolTipText(BYVAL id AS LONG, ttxt AS ASCIIZ * 50)
   FUNCTION PBMAIN
     DIM  i AS LONG
     InitCommonControls
     hWnd_ToolTip = CreateWindowEx( 0, "tooltips_class32", "", %TTS_ALWAYSTIP, 0, 0, 0, 0, 0, _
         BYVAL 0&, GetModuleHandle(BYVAL 0&), BYVAL 0&)

     DIALOG NEW 0, "Tooltip example",,, 400, 40, %WS_CAPTION OR %WS_SYSMENU TO hDlg
     CONTROL ADD BUTTON, hDlg, 101, "PROGRAM", 5,  5, 25, 25
     SetToolTipText 101, "This is a tooltip" & $CR & "Hoped this would be on another line.."
     CONTROL ADD BUTTON, hDlg, 102, "TOOLBAR", 45,  5, 350, 25
     SetToolTipText 102, "Another tooltip !"

     DIALOG SHOW MODAL hDlg
END FUNCTION

SUB SetToolTipText(BYVAL id AS LONG, ttxt AS ASCIIZ * 50)
     ti.cbSize   = LEN(ti)
     ti.uFlags   = %TTF_SUBCLASS OR %TTF_IDISHWND
        ti.hWnd     = hDlg
        ti.uId      = GetDlgItem(hDlg, id)
        ti.lpszText = VARPTR(ttxt)
        SendMessage hWnd_ToolTip, %TTM_ADDTOOL, 0, BYVAL VARPTR(ti)
END SUB

I found this on the net. Haven't tested it yet...
' Send a message to the tool tip window telling it to set 'the maximum tip
' width, to allow line breaking.
RetVal = SendMessage(hwndTT, TTM_SETMAXTIPWIDTH, 0, 80)

Yes, if you place the following line (into the code at the top of this thread) right after the CreateWindowEx() call, it works fine under Win2K. I've not tested onother platforms.

     DIALOG SEND hWnd_ToolTip, %TTM_SETMAXTIPWIDTH, 0, 200

The last parameter is the width in Pixels, and it respects CHR$(13) for line breaks.

See http://msdn.microsoft.com/library/de...axtipwidth.asp
