      On Mac the flags are a (undocumented in SU) bit-map. Experimentally, 10 (2 decimal) is left button, 1000 (8 decimal) is right button. It's never been clear to me what they meant you do to with a bit-map that isn't documented!

        Actually, I need the value of flags, for the onMouseMove method when the Left button is down.

        Apparently nothing that has a bit value of 1.

          Fredo, the flags were in there, the flag is 258...

          
onMouseMove; flags = 256
onMouseMove; flags = 256
onMouseMove; flags = 256
onMouseMove; flags = 256
onMouseMove; flags = 256
onMouseMove; flags = 256
onMouseMove; flags = 258  #left down starts here
onMouseMove; flags = 258  #left down
onMouseMove; flags = 258  #left down
onMouseMove; flags = 258  #left down
onMouseMove; flags = 258  #left down
onMouseMove; flags = 258  #left down
onMouseMove; flags = 258  #left down
onMouseMove; flags = 258  #left down
onMouseMove; flags = 258  #left down
onMouseMove; flags = 256  #left down released here
onMouseMove; flags = 256
onMouseMove; flags = 256
onMouseMove; flags = 256
onMouseMove; flags = 256
onMouseMove; flags = 256

            Thanks very much

            On Windows, the bitmask logic for onMouseMove is:

            • Left button down -> 1 (i.e. flags & 1 == 1)
            • Shift down -> 4
            • Ctrl down -> 8
            • Alt down -> 32
              This logic also applies to onLButtonDown (alwasy contains 1) and onLButtonUp

            On Mac, the bitmask logic seems different. The flags always include 256, and the button and modifiers are adding to that:

            • Left button down -> 2 (i.e. flags & 2 == 2)
            • Shift down -> ?
            • Ctrl down -> ?
            • Alt down -> ?

            John: would be kind to check what are the value of flags for the 3 modifiers. Also, check the flags on the methods onLButtonDown and onLButtonUp to see if they respect the logic too.

            Thanks

            Fred

              hi Fredo it's not so straight forward...
              there are two ways to get RButtonDown on a mac and I think they have different flags...
              but every mouse in the house has one fault or another...
              this one has a broken RButton...

              I'll update when I fix or buy a new mouse...

                Here's my output from a modified version of the event reporter John was using. It covers all the combinations of mouse moves with one or both buttons pressed as well as any of the four modifier keys. I added printout of the hex and decimal values of the flags because I find that easier to understand than trying to subtract the decimal values all the time.

                  Thanks. Very helpful.

                  Then it means that a portable flag decoding for onMouseMove could be

                  
#Flags for onMouseMove
if (RUBY_PLATFORM =~ /darwin/i)	
   def buttonLDown?(flags) ; flags & 2 == 2 ; end
   def shiftDown?(flags) ; flags & VK_SHIFT == VK_SHIFT ; end
   def ctrlDown?(flags) ; flags & VK_CONTROL == VK_CONTROL ; end
   def altDown?(flags) ; flags & VK_ALT == VK_ALT ; end
else
   def buttonLDown?(flags) ; flags & 1 == 1 ; end
   def shiftDown?(flags) ; flags & 4 == 4 ; end
   def ctrlDown?(flags) ; flags & 8 == 8 ; end
   def altDown?(flags) ; flags & 32 == 32 ; end
end

                    fredo,

                    you probably don't want to use VK_CONTROL on a mac...

                    256 = onMouseMove
                    258 = onMouseMove with LButtonDown

                    131072 ( VK_SHIFT )
                    131330 = onMouseMove with LButtonDown and ( VK_SHIFT )

                    524288 ( VK_ALT )
                    524578 = onMouseMove with LButtonDown and ( VK_ALT )

                    1048576 ( VK_COMMAND )
                    1048842 = onMouseMove with onLButtonDown and ( VK_COMMAND )

                    Usage example from Move Tool:
                    Shift = Lock move to the current inference direction ( VK_SHIFT )
                    Option = Toggles copy of selection ( VK_ALT )
                    Command =Toggles autofold of selection ( VK_COMMAND )

                    Control behaves differently depending on the order it is chosen...
                    262144 ( VK_CONTROL )
                    262403 = onMouseMove with LButtonDown THEN ( VK_CONTROL )
                    OR
                    262409 = onMouseMove with ( VK_CONTROL ) THEN LButtonDown

                    ( VK_CONTROL ) THEN LButtonDown will show a context menu...
                    LButtonDown THEN ( VK_CONTROL ) will NOT...

                      Thanks again.

                      Then, with some luck, the following portable code should make it on PC and Mac

                      
def buttonLDown?(flags) ; flags & MK_LBUTTON == MK_LBUTTON ; end
def shiftDown?(flags) ; flags & CONSTRAIN_MODIFIER_MASK == CONSTRAIN_MODIFIER_MASK ; end   #shift
def ctrlDown?(flags) ; flags & COPY_MODIFIER_MASK == COPY_MODIFIER_MASK ; end              #Ctrl (PC) or Command (Mac)
def altDown?(flags) ; flags & ALT_MODIFIER_MASK == ALT_MODIFIER_MASK ; end                 #Alt (PC) or Ctrl(Mac)

                      Fredo

                          Thanks in advance. I thought initially that the question was resolved somewhere in the forum, but could not find it (and it is anyway not described in the SU API doc).
