Is it possible to have <CR> in a text with Gadgettooltip ?

[skywalk]

Can anyone figure out why this code resets the Windows 10 desktop?
This works in Windows 7 and Windows 10 BEFORE the Creator Update this week.

Code: Select all

; ToolTipID() code from netmaestro
; http://www.purebasic.fr/english/viewtopic.php?t=36765&start=0
Procedure EnumProc(hwnd, lparam)
  Shared ctrl
  cn$ = Space(100)
  GetClassName_(hwnd, @cn$, 99)
  If UCase(cn$) = "TOOLTIPS_CLASS32"
    With ti.TOOLINFO
      \cbSize = SizeOf(TOOLINFO)
      \hwnd = GetParent_(ctrl)
      \uid = ctrl
    EndWith
    If SendMessage_(hwnd, #TTM_GETTOOLINFO, 0, @ti)
      PokeI(lparam, hwnd)
      ProcedureReturn 0
    Else
      ProcedureReturn 1
    EndIf
  Else
    ProcedureReturn 1
  EndIf
EndProcedure
ProcedureDLL.i ToolTipID(gadget)
  Shared ctrl
  ctrl = gadget
  EnumWindows_(@EnumProc(),@TTID)
  ProcedureReturn TTID
EndProcedure
OpenWindow(0, 180, 400, 270, 100, "GadgetTooltip")
ButtonGadget(0, 10, 30, 250, 30, "Button with Tooltip")
GadgetToolTip(0, "Multiline Tooltip" + #CRLF$ + "with [CR][LF].")
;////////
; This sendmessage() resets the Windows 10 desktop screen for several seconds.
; But the code still creates a multiline tooltip.
SendMessage_(ToolTipID(GadgetID(0)), #TTM_SETMAXTIPWIDTH, 0, 100)
;////////
Repeat
Until WaitWindowEvent() = #PB_Event_CloseWindow

EnumWindows_(), why so complicated?

[skywalk]

Maybe could be simpler, but your comment does not explain the Windows 10 Desktop reset with:
SendMessage_(ToolTipID(GadgetID(0)), #TTM_SETMAXTIPWIDTH, 0, 500)?
The reset is when modifying a PB created ToolTip.
I do not have a problem with my own ToolTip windows.

ToolTip(Tooln)=CreateWindowEx_(0,"ToolTips_Class32",#Empty$,#WS_POPUP | #TTS_NOPREFIX,0,0,0,0,WindowID,0,GetModuleHandle_(#Null),0)
I may have to go this way to keep the multi-line functionality in Windows 10.

Unless PB extends support for Multi-line Tooltips?

Hi
No problem PB 5.44 x86 Windows 10 x64
But like FB said why this too much hassle
Glad to see you back FB

Code: Select all

If OpenWindow(0, 0, 0, 220, 220, "CanvasGadget", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
    CanvasGadget(0, 10, 10, 200, 90)
    GadgetToolTip(0, "Tooltip for Button 0"+#CRLF$+"         It is OK"+#CRLF$+"     Just for now")
    CanvasGadget(1, 10, 110, 200, 100)
    GadgetToolTip(1, "Tooltip for Button 1"+#CRLF$+"         It is OK"+#CRLF$+"     Just for now")
    ttip = FindWindow_("tooltips_class32",0)
    SetWindowTheme_(ttip, @null.w, @null.w) 
    SendMessage_(ttip,#TTM_SETTIPTEXTCOLOR,#Red,0)
    SendMessage_(ttip,#TTM_SETTIPBKCOLOR,$CBFEFD,0)
    SendMessage_(ttip,#TTM_SETMAXTIPWIDTH,0,150)
    r.RECT : r\left = 4: r\right = 4: r\top = 4: r\bottom = 4
    SendMessage_(ttip,#TTM_SETMARGIN,0,r)
    SetWindowLongPtr_(ttip,#GWL_STYLE,GetWindowLongPtr_(ttip, #GWL_STYLE)|#TTS_BALLOON)
    
    Repeat
      Event = WaitWindowEvent()
          
      If Event = #PB_Event_Gadget And EventGadget() = 0 
        If EventType() = #PB_EventType_LeftButtonDown Or (EventType() = #PB_EventType_MouseMove And GetGadgetAttribute(0, #PB_Canvas_Buttons) & #PB_Canvas_LeftButton)
          If StartDrawing(CanvasOutput(0))
            x = GetGadgetAttribute(0, #PB_Canvas_MouseX)
            y = GetGadgetAttribute(0, #PB_Canvas_MouseY)
            Circle(x, y, 10, RGB(Random(255), Random(255), Random(255)))
            StopDrawing()
          EndIf
        EndIf
      EndIf    
      
    Until Event = #PB_Event_CloseWindow
  EndIf

Hi RASHAD,
Your example does not work when compiled x64 on Windows 10.
No color or multi-line tooltip. Just standard tooltip.
But, your code does not reset the Windows 10 Desktop.

[RASHAD]

Hi skywalk
My version works fine with PB x64
But I just noticed that you are running the enumerate from within the SendMessage
So try the next

Code: Select all

GadgetToolTip(0, "Multiline Tooltip" + #CRLF$ + "with [CR][LF].")
ttid = ToolTipID(GadgetID(0))
;////////
; This sendmessage() resets the Windows 10 desktop screen for several seconds.
; But the code still creates a multiline tooltip.
SendMessage_(ttid, #TTM_SETMAXTIPWIDTH, 0, 100)
;////////

[skywalk]

Yeah, that has no effect on the latest Windows 10(Creator Update).
I tried PB v56 x86 & x64.
The same code works fine on Windows 7.

Does anyone know how to use Spy++ to capture a tooltip window?
The tooltip window pops up but Spy++ does not display a change.

[skywalk]

Thanks RASHAD for asking to break out the ToolTipID().
Digging more, ToolTipID() was resetting the Windows 10 Desktop.

Code: Select all

SendMessage_(hwnd, #TTM_GETTOOLINFO, 0, @ti);<-- THIS LINE RESETS WINDOWS 10 DESKTOP!?
; NOT This...
SendMessage_(ttid, #TTM_SETMAXTIPWIDTH, 0, 150)

So, I tried TS_Soft's approach using PB's internal gadget properties and no RESETS!
Whew!

Code: Select all

Again, why EnumWindows_()?

Code: Select all

OpenWindow(0,0,0,300,200,"Tooltips Demo",#WS_SYSMENU | #WS_CAPTION | 1)
ButtonGadget(0,5,5,105,25,"New Document")

hwndToolTip = CreateWindowEx_(0,"tooltips_class32",0,0 | #TTS_CLOSE,0,0,0,0,0,0,0,0)
SendMessage_(hwndToolTip,#TTM_SETMAXTIPWIDTH,0,300)
SendMessage_(hwndToolTip,#TTM_SETTITLE,1,"Caption")

Procedure AddToolTip(hwnd,Gadget,Text.s)
	Protected tti.TOOLINFO
	
	tti\cbSize = SizeOf(TOOLINFO)
	tti\uFlags = #TTF_SUBCLASS
	tti\hwnd = GadgetID(Gadget)
	tti\rect\right = GadgetWidth(Gadget)
	tti\rect\bottom = GadgetHeight(Gadget)
	tti\lpszText = @Text
	
	ProcedureReturn SendMessage_(hwnd,#TTM_ADDTOOL,0,tti)
EndProcedure

AddToolTip(hwndToolTip,0,"New Document" + #CRLF$ + "Multiline")

While WaitWindowEvent() ! #PB_Event_CloseWindow : Wend

Jeez, I thought I posted in English?
There is NO reset problem creating your own tooltip window.
Reset occurs only on Windows 10(Creator Update) when you query PB's internal tooltip window with:
SendMessage_(hwnd, #TTM_GETTOOLINFO, 0, @ti);<-- THIS LINE RESETS WINDOWS 10 DESKTOP!?
Why the fascination with EnumWindows_()

[Fluid Byte]

Jeez, I thought I posted in English?

Sure, unfortunately I didn't see the part where you said EnumWindows_() is a requirement.

There is NO reset problem creating your own tooltip window.

Then create your own tooltip, problem solved.

Reset occurs only on Windows 10(Creator Update) when you query PB's internal tooltip window with:
SendMessage_(hwnd, #TTM_GETTOOLINFO, 0, @ti);<-- THIS LINE RESETS WINDOWS 10 DESKTOP!?

The recent Windows creator update broke a lot of things and there is nothing you can do about that expect to wait for MS to release a patch. Also you are modifying PB gadgets with external API and wounder why something broke, that's adorable.

Why the fascination with EnumWindows_()

You still failed to explain why it is necessary. Use the code I provided and the problem is gone. I don't understand why you make it complicated without a reason.

[skywalk]

My gui's are created from single line macros that drive all settings and enumerations for pb's gadgets,shortcuts,menus,toolbars,etc.
The multiline tooltip works with the flow I showed. Adding my own tooltip windows would work also, but more code to write/debug in my gui generator. Each gadget handle is assumed to be the sole target of any action.

[Fluid Byte]

So is this problem solved?

[skywalk]

Yes, you showed there is no error creating our own tooltip window and I showed the workaround if you use PB's internal Tooltip window. It is up to the user to choose their preferred method. Better still if PB eventually supports multiline tooltips.
