I have a dialog built through resedit, and everything is going well. The buttons are working fine, but there's a slider to allow custom control. The problem is when I move the slider it's always constantly updating(through what I assume is CoreMessage() c4d.EVMSG_CHANGE. This is problematic because it makes an insane amount of undo steps. So I'm curious if there is a way to get the value from the slider when the mouse is released and not while dragging?

Can you possibly post an example?

I'm curious about where (which method) you are reading the data from the slider. And how you are using UNDO's.
Maybe that will help us figure out what you're looking for.

Sorry it took me so long to respond. I'm using Undo's in the normal way. Basically in my Command() function I am doing:

if id==10013:
self.Tweening(self.GetReal(10013))

inside of my Command() function, that's all. Obviously 10013 is the ID of the slider itself. It seems to store each value as I drag it. I want it to not run until I let go of my click instead of as im dragging the slider.

This is a coffe snippet that should do what you want.
Just use GetInputSate() in Python.

if(msg->GetData(BFM_ACTION_INDRAG) == FALSE && msg->GetData(BFM_ACTION_VALCHG) == FALSE)

Thanks Nux,

But is there something I must do first to set the msg basecontainer? I tried InputState() but I am not sure which should be the the askdevice and which should be the askchannel.

Here's an example:

   if id == 1002:  # The slider's ID  
  getvalue = self.GetReal(1002)           # Gets the value of the slider    
  bc = c4d.BaseContainer()                # Create a container to hold the slider's state  
  state = self.GetInputState(1002, 0, bc) # Gets the state of the slider  
  if state == False:                      # If the slider has stopped being dragged   
   bc.SetReal(0,getvalue)            # Set the value of the container's first element to the slider's value  
   print bc[0]                            # Print the value of the container's first element;  
                                          # In other words....The slider's current position       
  
c4d.EventAdd()

This will get the slider's value. And store it in the new container.
But only after the slider has stopped moving.

This does not however, seem to have any impact on using undo's as far as I can see.
So if you figure out how to use undo's on the sliders themselves. Please post it here.
Because it's something I'd like to know how to do myself. And I can't find any examples of how to do it anywhere.

Hey Scott,

Thanks for the code, but unfortunately it does not work. I will try to present the problem a little bit clearer to hopefully show the problem but I can't post much of the code(in addition to not being able to show the code, there's also just a ton of code too :) )

If you use that Code, even if I just click on my slider and not drag, I get at least 2 prints to the console. If I click and drag, I get much much more. See this image here: http://dl.dropbox.com/u/5823011/ConsoleOutput.jpg

That was me just draging the slider a little bit.

The reason why this is bad is because I have a function that does some stuff with keys. That function on it's own is working great, it works with the buttons, etc. But because when I adjust the slider it's executing so many times, the function gets called so many times(it makes far too many keys.)

I basically just need to get the value from when I let go, and no matter what I do, I get something like that console pic. :/.

I really appreciate the efforts you guys are putting in though. Thanks for the help so far.

Sebastian pointed me to looking at the Command's bc(ie msg) but I apparently was not passing a BC in my Command() function(was doing msg=None). So I changed that.

Then he suggested I do:

if id==10013:
if bc.GetBool(c4d.BFM_ACTION_INDRAG) is False:
doFunction()

Easy Peasy. I feel stupid now.

The code you posted does the same thing.
The slider's changes get cached. Then it returns them all, once the function is called:

def Command(self, id, msg) :  
   
if id == 1002:  # The slider's ID  
  bc = c4d.BaseContainer()     
  if bc.GetBool(c4d.BFM_ACTION_INDRAG) is False:     
   print self.GetReal(1002)   
  
return True

What do you mean you changed msg from msg=none?
What did you change it to?

I was originally using:

def Command(self, id, msg=None) :

I eventually changed it so it wasn't None(I have no clue why I even made it None), and then what I wrote appeared to work. I dunno.

if id==10013:
   if bc.GetBool(c4d.BFM_ACTION_INDRAG) is False:
   print "YEEEEEEEEHAW!!!!"

It still gets all the values like my image shows, but that extra if allows me to only execute it at the end.

The code doesn't make sense. You create a new BaseContainer and try to get a value. This vill obviously return 'None' since the container didn't ever recieve a value for c4d.BFM_ACTION_INDRAG.

Change bc to msg.

Ahh yes i see the confusion now my bad.

It is as nux said you need to run that check from the basecontainer passed in the command function. Usually that is msg. For some reason i changed it to be bc so it was Command(self, id, bc). That is the bc i refer to in my code but normally that would be msg.
