GadgetToolTip usable with multiple lines ?

Posted: Tue Oct 18, 2011 2:36 pm

Is it possible to have GadgetToolTip to print several lines ?

Code: Select all

  GadgetToolTip(x,"Why are multiple"+#CR$+"lines NOT possible???")
For me, carriage return is considered as a blank square when tooltip appears.

Is there a way to bypass this problem ?

Here's an old code (2004) written by Sparks and Andre.It is rewritten (1) for version 4.51 of Pure basic.

You can easily cause the tooltip to wordwrap by sending the #TTM_SETMAXTIPWIDTH message. However, in order to do that you need to get the handle of the tooltip Purebasic created for you:

Code: Select all

Procedure TT_CBTHookProc(nCode, wParam, lParam) 
  Shared _Hook, TT_HWND
  Select nCode 
    Case #HCBT_CREATEWND 
      *pcbt.CBT_CREATEWND = lParam 
      *pcs.CREATESTRUCT = *pcbt\lpcs 
      Select PeekS(*pcs\lpszClass)
        Case "tooltips_class32"
          TT_HWND = wParam
      EndSelect
  EndSelect
  ProcedureReturn CallNextHookEx_(_Hook, nCode, wParam, lParam) 
EndProcedure

Procedure GadgetToolTipEx(gadget_number, tooltip_text$)
  Shared _Hook, TT_HWND
  _Hook = SetWindowsHookEx_(#WH_CBT, @TT_CBTHookProc(), #Null, GetCurrentThreadId_()) 
  GadgetToolTip(gadget_number, tooltip_text$)
  UnhookWindowsHookEx_(_Hook)
  ProcedureReturn TT_HWND
EndProcedure

OpenWindow(0,0,0,320,240,"")
StringGadget(1,20,40,200,20,"stuff")
ttid = GadgetToolTipEx(1, "This is a tooltip        with multiple lines  ")
SendMessage_(ttid, #TTM_SETMAXTIPWIDTH, 0, 100)
Repeat:Until WaitWindowEvent()=#PB_Event_CloseWindow

Thanks netmaestro, that's perfect. :)

Also possible :

Code: Select all

Structure PB_Globals
  CurrentWindow.i
  FirstOptionGadget.i
  DefaultFont.i
  *PanelStack
  PanelStackIndex.l
  PanelStackSize.l
  ToolTipWindow.i
EndStructure

Import ""
  PB_Object_GetThreadMemory(*Mem)
  PB_Gadget_Globals
EndImport

Procedure ToolTipID() 
  Protected *PB_Globals.PB_Globals 
  *PB_Globals = PB_Object_GetThreadMemory(PB_Gadget_Globals) 
  ProcedureReturn *PB_Globals\ToolTipWindow 
EndProcedure

OpenWindow(0,0,0,320,240,"")
StringGadget(1,20,40,200,20,"stuff")
GadgetToolTip(1, "This is a tooltip        with multiple lines  ")
ttid = ToolTipID()
SendMessage_(ttid, #TTM_SETMAXTIPWIDTH, 0, 100)
Repeat:Until WaitWindowEvent()=#PB_Event_CloseWindow

Code: Select all

GadgetToolTip(x,"Why are multiple"+#CR$+"lines NOT possible???")
Works for me! (on Mac) Maybe you need a line feed?

Code: Select all

GadgetToolTip(gethefid(MFile,47),"Month spent/"+Chr(13)+"Posted balance/"+Chr(13)+"Total balance")

Doesn't work for me under XP : chr(13) is considered as a blank square in the tooltip.
netmaesto and gnozal's snippets solve my problems. :)

I was suggesting using (for the linefeed)

Code: Select all

#CRLF$
but maybe it just doesn't work on your version.

Under Windows I think a CHR(10) is used for linefeeds, but I could be wrong :-)

Absolutely, but same result. :(
Both solutions (netmaestro and gnozal) are very interesting.

For a Windows solution using #CR$ as a ToolTip linefeed take a look into
a previous code example from me that utilizes netmaestro's ToolTipID()
