Does Anyone know how to check to see if the middle mousewheel is being spun?

Here's the code I'm trying but it doesn't work.

  
if (GetInputEvent(BFM_INPUT_KEYBOARD, state))  
  {  
      LONG key = state.GetLong(BFM_INPUT_QUALIFIER);  
      if((key & QCTRL)){  
  
          if (msg.GetLong(BFM_INPUT_CHANNEL) == BFM_INPUT_FINGERWHEEL)  
          {  
              GePrint("The Wheel is spinning");  
          }  
      }  
  }  

It works if I use BFM_INPUT_MOUSELEFT  but doesn't work with BFM_INPUT_FINGERWHEEL or  BFM_INPUT_MOUSEWHEEL   Any thoughts?

thanks,

Shawn

BFM_INPUT_MOUSEWHEEL should work. Try to comment out the BFM_INPUT_KEYBOARD scope and see if that changes anything. Or try BFM_INPUT_MOUSE.

Well I simplified it down to this..

  
if (msg.GetLong(BFM_INPUT_CHANNEL)==BFM_INPUT_MOUSEMIDDLE)  
              {  
                  GePrint("The Wheel is Spinning");  
              }  

But still nothing..  If I use BFM_INPUT_MOUSEMIDDLE it doesn't work,  But if I use BFM_INPUT_MOUSELEFT it does work.  Is this a bug?  or is there a limitation I am not aware of?

This also works but not when I use BFM_INPUT_MOUSEMIDDLE

So you want to check if the Mousewheel is being turned?
What I miss in your code is the actual check for mousewheel activity
Try BFM_INPUT_MOUSEWHEEL.

Hey sorry Jack.   I did use BFM_INPUT_MOUSEWHEEL too..  And nothing hapens.  The inly thing that's works is if I use BFM_INPUT_MOUSELEFT.  Not sure what's going on..   Lol

Still, you should concentrate your efforts on making BFM_INPUT_MOUSEWHEEL work, because MOUSEMIDDLE won't get you anywhere if you want to query the wheel.

Also, I think StartDrag() etc won't help here, as a mousewheel movement is not a drag AFAIK. Try GetInputState().

Maybe send some more code, as we don't even know what type of plugin you're writing.

Hey Jack,

Here's the whole MouseInput() function.

  
ool ZoomToCursor::MouseInput(BaseDocument *doc, BaseContainer &data, BaseDraw *bd, EditorWindow *win, const BaseContainer &msg)  
{  
  BaseContainer state;  
  Real mx = msg.GetReal(BFM_INPUT_X);  
  Real my = msg.GetReal(BFM_INPUT_Y);  
  
  LONG button;  
    
  switch (msg.GetLong(BFM_INPUT_CHANNEL))  
  {  
      case BFM_INPUT_MOUSELEFT : button=KEY_MLEFT; break;  
      case BFM_INPUT_MOUSERIGHT: button=KEY_MRIGHT; break;  
      default: return TRUE;  
  }  
  
  if(GetInputState(BFM_INPUT_MOUSE, BFM_INPUT_MOUSEWHEEL, data)){  
        
      BaseContainer bc = BaseContainer();  
      win->BfGetInputEvent(BFM_INPUT_MOUSE,&bc);  
      if (msg.GetLong(BFM_INPUT_CHANNEL)==BFM_INPUT_MOUSEWHEEL)  
      {  
          GePrint("The Wheel is Spinning");  
      }  
  }  
  
  return TRUE;  
}  
  

This is a tool plugin that I want to identify if the mousewheel is turning.  If it is, I want some code to be initiated.  This is really the only thing I have with this particular plugin at the moment because it all hinges on reading if the mouse wheel is turning.   I just added the :

if(GetInputState(BFM_INPUT_MOUSE, BFM_INPUT_MOUSEWHEEL, data)){

and it still doesn't print the text to the console.   Did I use the wrong device and channel constants for GetInputState() ?

I am also wondering if I am using the wrong basecontainer for storing the data.

Do you know how GetInputState() determines if the input device is active?  That might offer some more insight as to why this isn't working.

Howdy,

Is it possible that the mouse wheel action is intercepted somewhere else when the mouse is in the viewport to control zooming the view and can't be access for anything else? I think that's the case with the right mouse button, too isn't it, to bring up a menu?

Adios,

hmm, you did try

if ( bc.GetLong(BFM_INPUT_CHANNEL)==BFM_INPUT_MOUSEWHEEL)

instead of msg.GetLong... right?

Yeah,  still nothing.  I'm wondering if Cactus Dan is right about this one.

The left mouse button must be clicked when using the wheel, just as it is necessary in the c4d live selection tool. The wheel alone will of course not work! I thought that was clear in the first place. So yes, that might be the issue then?

Samir's code is how to do it. It's not possible to react on scroll wheel actions alone. You need to to hold left click.

I was wondering how well this mouse wheel thing works for you guys. Because it's very Erratic on my system: Vista x64.

The Liquid Tool example in the SDK has this same mouse wheel code in it to display the radius setting when the middle mouse wheel is spun. Plus I also added the line GePrint("Scrolling"); to it just as a test.

Although it works. It's very hit and miss.
Sometimes the wheel spins several times before C4D catches it and then prints the results to the console. And other times It catches it almost immediately when the wheel is spun.
So I was wondering if this is a known limitation. Or a problem with my system?

I will take a look at the Liquid Tool example when I get home and see if I can get it to work right.  I suppose that if that's the only way to get it to work then it will have to do.

Okay so I am trying to accomplish this again but with the right mouse button.  I was never able to get it to work fluidly with the middle mouse button either.  The problem is that when you hold down the left mouse button and then either roll the mouse wheel or click the right mouse button, depending on the code implementation, it responds very sporadically,  In the code posted below, I try to hold the left mouse button and then click the right mouse button and I need to click many different times and move the mouse around a lot in order to get it to run once..   Does anyone see any reason why this would be happening?  Am I leaving out some sort up update that causes this to function properly?

Here's the code I have:

  
  
  Real dx, dy;  
  BaseContainer device;  
  
  win->MouseDragStart(button,mx,my,MOUSEDRAGFLAGS_DONTHIDEMOUSE|MOUSEDRAGFLAGS_NOMOVE);  
  while (win->MouseDrag(&dx,&dy,&device)==MOUSEDRAGRESULT_CONTINUE)  
  {  
      if(dx == 0 && dy == 0) continue;  
        
      BaseContainer bc = BaseContainer();  
      win->BfGetInputEvent(BFM_INPUT_MOUSE, &bc);  
      if (bc.GetLong(BFM_INPUT_CHANNEL) == BFM_INPUT_MOUSERIGHT)  
      {  
          GePrint("RIGHT BUTTON PRESSED");  
      }  
  }  
  
  if (win->MouseDragEnd()==MOUSEDRAGRESULT_ESCAPE)  
  {  
  }   
  

Thanks in advance.
