Return-Values of WindowMouseX() and WindowMouseY()

[Axolotl]

Some observations on the return values of the two functions:
If the mouse pointer is outside the window, -1 is displayed for both values under Win11.
Under Linux there are values <> -1. Looks like wrong behavior to me.... or maybe a bug?
Small test code:

Code: Select all

Macro RStr(Value, Length) 
  RSet(Str(Value), Length) 
EndMacro 

  If OpenWindow(0, 0, 0, 320, 120, "Example...", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
    StickyWindow(0, 1) 

   TextGadget(1, 10, 10, 300, 20, "")
   TextGadget(2, 10, 40, 300, 20, "")

   AddWindowTimer(0, 1, 100) 
   Repeat
     Event = WaitWindowEvent()
     Select Event
       Case #PB_Event_DeactivateWindow  : Debug "bye " 
        Break 

       Case #PB_Event_Timer 
        mx = DesktopMouseX() 
        my = DesktopMouseY() 
        SetGadgetText(1, "Desktop Mouse Pos: " + RStr(mx, 4) + ", " + RStr(my, 4)) 

        mx = WindowMouseX(0) 
        my = WindowMouseY(0) 
        SetGadgetText(2, "Window Mouse Pos: " + RStr(mx, 4) + ", " + RStr(my, 4)) 
       
     EndSelect
   Until Event = #PB_Event_CloseWindow
 EndIf

Different OS behaviour.

Nice to see, but a bug Fred must say.

Of course Fred decides on errors or features.

If you say different OS behavior...
Isn't it the purpose of the PB functions to make it the same as much as it can?
Should I share my observations regarding different behavior or is that to boring at all?

I learnt today that I have to check on both X and Y if I want to be sure the mouse is moving outside the window.
