on osx : the value change only when the mouse is released : not good
on windows : the value change when the trackbbar position change
Code: Select all
Enumeration
#Window_0
EndEnumeration
Enumeration
#text_0
#tb_0
EndEnumeration
Procedure InitWindow_0()
OpenWindow(#Window_0, 0, 0, 290, 130, "", #PB_Window_SystemMenu)
TextGadget(#text_0,10,10,50,20,"0",#PB_Text_Border|#PB_Text_Center)
TrackBarGadget(#tb_0,10,70,150,25,0,100)
EndProcedure
initwindow_0()
Repeat
Select WaitWindowEvent()
Case #PB_Event_Gadget
Select EventGadget()
Case #tb_0
SetGadgetText(#text_0,Str(GetGadgetState(#tb_0)))
EndSelect
Case #PB_Event_CloseWindow
CloseWindow(#window_0)
Break
EndSelect
ForEver
End

It's not specific to PB 5.00
It does the same on PB 4.61 and 4.60 (and probably versions below ; I don't have them anymore)
But... should it be considered as a bug ?

It's a missing feature I'd say, like live scrollbars on all OSes.

Unfortunately it doesn't work live on OS X, but we can't do anything about it.

I assume it's the same problem you mentioned before about the PureBasic event queue being locked until you release the button ?
OS X itself calls the target/action also while the trackbar gadget is used.

Yes, it's the same issue.

Oh well, looks like Apple are well on the way to self-destruct again, so it won't be a problem in the future

It's not an OS X issue, it's a PureBasic issue.
Of course scrollbars and sliders are working realtime in the OS itself.

...it won't matter whose issue it is if the platform isn't there anymore - but I jest.

Well, this response is way late but it's supported now in PB 5.21 with BindEvent. I modified the above example as follows and have only tested it in OSX Mavericks.
Code: Select all
Enumeration
#Window_0
EndEnumeration
Enumeration
#text_0
#tb_0
EndEnumeration
Procedure GadgetHandler()
SetGadgetText(#text_0,Str(GetGadgetState(#tb_0)))
EndProcedure
Procedure InitWindow_0()
OpenWindow(#Window_0, 0, 0, 290, 130, "", #PB_Window_SystemMenu)
TextGadget(#text_0,10,10,50,20,"0",#PB_Text_Border|#PB_Text_Center)
TrackBarGadget(#tb_0,10,70,150,25,0,100)
BindEvent(#PB_Event_Gadget, @GadgetHandler())
EndProcedure
initwindow_0()
Repeat
Select WaitWindowEvent()
Case #PB_Event_CloseWindow
CloseWindow(#window_0)
Break
EndSelect
ForEver
End
