Some IDCMP questions...

Hi,

To finish off the title:
...and an IDCMP port rattling like a machine gun.

When a window (MY window, that is) is active, the IDCMP port gets innundated with mousemove messages, although I modified the IDCMP 'filter' to NOT pass these messages:

  1.      if (IIntuition->GetWindowAttr((__GE)->ge_Window[ACTIVEWOID], WA_IDCMP, (APTR)&IDCMP, 4) != 0)
  2.       {
  3.        (__GE)->ge_DefaultIDCMP = IDCMP;
  4.        _PrintFlags(IDCMP);
  5.        IDCMP = (__GE)->ge_ActiveIDCMP;
  6.  
  7.        if (IIntuition->SetWindowAttr((__GE)->ge_Window[ACTIVEWOID], WA_IDCMP, (APTR)&IDCMP, 4) != 0)
  8.         {
  9. # ifdef DEBUG
  10.          uint32 IDCMP_Modified = 0;
  11.  
  12.          if (IIntuition->GetWindowAttr((__GE)->ge_Window[ACTIVEWOID], WA_IDCMP, (APTR)&IDCMP_Modified, 4) != 0)
  13.           {
  14.            _PrintFlags(IDCMP_Modified);
  15.           }
  16.          _ElseError("Get Window Attribute(s) DEBUG");
  17.  
  18. # endif
  19.  
  20.         }
  21.        _ElseError("Set Window Attribute(s)");
  22.  
  23.       }
  24.      _ElseError("Get Attributes");

In this part both _PrintFlags() and _ElseError() are functionlike macros.

The output from _PrintFlags() is this:

  1. FLAGS: *               IDCMP [ 0000 1110  1100 1100  0010 0110  0101 1100 ]
  2. FLAGS: *      IDCMP_Modified [ 0101 0011  0010 1011  0000 1010  0001 1000 ]
  3. FLAGS: *               IDCMP [ 0000 0000  0000 0000  0100 0000  0110 0010 ]

The 1st line is the IDCMP-flags as default by opening a Window.
The 2nd line is the applied IDCMP-flags after modification (a far cry from...).
The 3rd line is the set of IDCMP-flags I had in mind.

All according to this scheme:

The WMHI-Class messages I get are (from the console partly):

  1. FLOW : ----- Handle_AllSignals entered
  2. FLOW : ------ Handle_WMHISignal entered
  3. DEBUG: Message gotten [ 000F0000 ] -- Class [ 15 ] - [ Mousemove ] rejected *
  4. FLOW : ------ Handle_WMHISignal vacated
  5. FLOW : ------ Handle_WMHISignal entered
  6. DEBUG: Message gotten [ 000F0000 ] -- Class [ 15 ] - [ Mousemove ] rejected *
  7. FLOW : ------ Handle_WMHISignal vacated
  8. FLOW : ------ Handle_WMHISignal entered
  9. DEBUG: Message gotten [ 000F0000 ] -- Class [ 15 ] - [ Mousemove ] rejected *
  10. FLOW : ------ Handle_WMHISignal vacated
  11. FLOW : ------ Handle_WMHISignal entered
  12. DEBUG: Message gotten [ 000F0000 ] -- Class [ 15 ] - [ Mousemove ] rejected *
  13. FLOW : ------ Handle_WMHISignal vacated
  14. FLOW : ------ Handle_WMHISignal entered
  15. DEBUG: Message gotten [ 000F0000 ] -- Class [ 15 ] - [ Mousemove ] rejected *
  16. FLOW : ------ Handle_WMHISignal vacated
  17. FLOW : ------ Handle_WMHISignal entered
  18. DEBUG: Message gotten [ 000F0000 ] -- Class [ 15 ] - [ Mousemove ] rejected *
  19. FLOW : ------ Handle_WMHISignal vacated
  20. FLOW : ------ Handle_WMHISignal entered
  21. DEBUG: Message gotten [ 000F0000 ] -- Class [ 15 ] - [ Mousemove ] rejected *
  22. FLOW : ------ Handle_WMHISignal vacated
  23. FLOW : ------ Handle_WMHISignal entered
  24. DEBUG: Message gotten [ 000F0000 ] -- Class [ 15 ] - [ Mousemove ] rejected *
  25. FLOW : ------ Handle_WMHISignal vacated
  26. FLOW : ------ Handle_WMHISignal entered
  27. DEBUG: Message gotten [ 000F0000 ] -- Class [ 15 ] - [ Mousemove ] rejected *
  28. FLOW : ------ Handle_WMHISignal vacated

and finally:

  1. FLOW : ------ Handle_WMHISignal entered
  2. DEBUG: Message gotten [ 00010000 ] -- Class [  1 ] - [ Close window ] accepted
  3. FLOW : ------- WMHI_CloseWindow entered
  4. FLOW : ------- WMHI_CloseWindow vacated
  5. FLOW : ------ Handle_WMHISignal vacated
  6. FLOW : ----- Handle_AllSignals vacated

and are generated by this function:

  1. BOOL Handle_WMHISignal(struct ExecParam *xn)
  2. {
  3. INFO_ENTER
  4.  BOOL Success = FALSE;
  5.  
  6.  uint32 MsgClass;
  7.  
  8.  while (((__GE)->ge_WMHI_Message = IIntuition->IDoMethod((__GE)->ge_WinObj[ACTIVEWOID], WM_HANDLEINPUT, 0)) != WMHI_LASTMSG)
  9.   {
  10. #ifdef DEBUG
  11.    IDOS->Printf("DEBUG: Message gotten [ %08lx ] -- Class [ %2lu ]", (__GE)->ge_WMHI_Message, ((__GE)->ge_WMHI_Message & WMHI_CLASSMASK) >> 16);
  12. #endif
  13.  
  14.    if (
  15.        ((MsgClass = ((((__GE)->ge_WMHI_Message & WMHI_CLASSMASK) >> 16) - 1)) < 20) &&
  16.        ((__GE)->ge_WMHIFilter & (1L<<MsgClass)) &&
  17.        ((__GE)->ge_WMHI_ClassJumpTable[MsgClass] != NULL)
  18.       )
  19.     {
  20. #ifdef DEBUG
  21.      IDOS->Printf(" - [ %-15s ] accepted\n", WMHI_Class[MsgClass]);
  22. #endif
  23.  
  24.      Success = (__GE)->ge_WMHI_ClassJumpTable[MsgClass](xn);
  25.     }
  26. #ifdef DEBUG
  27.    else
  28.     {
  29.      IDOS->Printf(" - [ %-15s ] rejected *\n", WMHI_Class[MsgClass]);
  30.     }
  31. #endif
  32.   }
  33.  
  34. INFO_VACATE
  35.  return Success;
  36. }

a function in which I incorporated this line:

  1.        ((__GE)->ge_WMHIFilter & (1L<<MsgClass)) &&

to filter out these unsollicited messages.

Why do I get all these messages?
Why is the applied IDCMP 'filter' so entirely different from BOTH the first automatically generated one AND the one I had in mind?

Re: Some IDCMP questions...

Modified this line

  1.        if (IIntuition->SetWindowAttr((__GE)->ge_Window[ACTIVEWOID], WA_IDCMP, (APTR)&IDCMP, 4) != 0)

to

  1.        if (IIntuition->SetWindowAttr((__GE)->ge_Window[ACTIVEWOID], WA_IDCMP, (APTR)IDCMP, 4) != 0)

and that worked miracles...
