Update Status bar from inside a script

You need to make your computer stop processing the script per iteration for a short period of time to see the value change take place using sleep().

import c4d, time  
def main() :

It is still not working
Could it be that it is because I also have a dialog?
However, the main loop is after the Command method of the dialog closes the dialog (and, yet, the closing only really happens after the main loop finishes, don't really understand why).
This is, in a nutshell, my main loop:

  
lim=len(all_files)   
count=100.0/lim   
  
for c,i in enumerate(all_files) :   
               
    # perform some stuff with the filename, inside the all_files list   
    # copy and erase some files, based on the processed filename   
  
    # only update the status every 100 items   
    if c % 100 == 0:   
        c4d.StatusSetBar(int(c*count))   
        c4d.StatusSetText("%s / %s" % (c,lim))   
        time.sleep(.1)   
                 
c4d.StatusClear()

I have already tried:

  
c4d.EventAdd(c4d.EVENT_FORCEREDRAW)

and

  
c4d.SendCoreMessage(c4d.COREMSG_CINEMA,c4d.BaseContainer(c4d.COREMSG_CINEMA_FORCE_AM_UPDATE))

All of it with a time.sleep(.25) in front... and nothing!!
I still get no refresh in the status bar.
I really would like to get some feedback to the user in the status bar, as the process can take a few seconds to finish.

I don't know about anyone else. But I'm not totally clear on what you're doing.
It sounds like you're having threading issues. But it's not clear to me.
Is there any way you can post a simple working example?
Something that runs, has a GeDialog in it, and your progress bar code in it.

FYI:
I've noticed that the support guys don't usually answer questions on the weekends anymore like they used to.
They seem to be sticking to regular business hours now. Which is understandable.
So if you ask a question on Friday. It can take up to 3 days to get a reply from them.

I'm writing a script. It is not a full plugin. So, I just have a GeDialog to define the parameters but my code, the one that should update the progress bar, is outside of the code of the dialog.
So, in my main I have this:

  
dlg=my_dialog()   
dlg.Open(c4d.DLG_TYPE_MODAL, defaultw=300, defaulth=50)   
the_path=dlg.the_path   
the_name=dlg.the_name   
       
if not dlg.ok: return

I have some variables inside the dialog class (the_path, the_name and ok).
If ok is True, the user pressed the OK button.
If ok is False, the user pressed the Cancel button.
This is all set in the Command method.
So, the code that follows the last line of code above is the one, inside the main that should update the progress bar.
A strange thing that occurs is that my Command method includes this:

  
def Command(self,id, msg) :   
  
    if id==B_CANCEL:   
        self.ok=False   
        self.Close()   
        return True   
  
    if id==B_OK:               
        self.ok=True   
        self.Close()   
        return True

...and the dialog closes if I press the Cancel button.
But if I press the OK button, the dialog only closes after my whole main loop finishes. And that is already outside the dialog code.
Very weird.

I'm afraid I'm still not clear on the problem.
Here is an example that implements the progressbar in two different places.
One is in the GeDialog's Command() method. The other one is executed in the main() method.
They are both working as expected for me.

import c4d, time  
from c4d import gui  
  
class MyDialog(gui.GeDialog) :  
  
  BUTTON_ID = 1001  
    
  def CreateLayout(self) :  
      self.AddButton(self.BUTTON_ID, c4d.BFH_SCALE|c4d.BFV_SCALE, 100, 25, "Close Dialog")   
      return True  
  
  def InitValues(self) :          
      return True  
  
  def Command(self, id, msg) :  
        
      if id == self.BUTTON_ID:  
            
          #If you use this code  
          #The progressbar will update. Then the dialog will close when it's finished  
            
          """for i in xrange(0, 101) :  
  
              #Convert the value to a string. And add the percent symbol to it  
              value = str(i)  
              value += "%"                    
              c4d.StatusSetText( value )  
        
              time.sleep(.10)"""    
                
          c4d.StatusClear()            
            
          #Closes the dialog after the above code runs  
          self.Close()  
            
      return True  
  
if __name__=='__main__':  
  dlg = MyDialog()  
  dlg.Open(dlgtype=c4d.DLG_TYPE_MODAL, defaultw=200, defaulth=200)  
    
  #If you use code  
  #The dialog will close first. Then the progressbar will update  
  """for i in xrange(0, 101) :  
      #Convert the value to a string. And add the percent symbol to it  
      value = str(i)  
      value += "%"  
      c4d.StatusSetText( value )          
      time.sleep(.10)  
        
  c4d.StatusClear()"""

The only thing I can think of is to maybe try not using True after each button code. Just call True once at the end of the Command() method. But I doubt that would make a difference.
Sorry. I'm not being much help.

It's works fine for me on a PC. You're using a mac right?
In the past I've had several mac users tell me that my dialog.Close() code did not work for them.
I don't own one so I can't test it. But based on my experiences, macs definitely have problem with the dialog.Close() function.

Thank you, Scott.
So, it is a Mac issue
Well, my code works, except for that problem.
I will try to find a workaround for it.
Damn!!! It should work fine on both platforms.

Hello,

the following script works for me on both win and mac (R17 SP2) :

  
class TestDialog(gui.GeDialog) :  
   
  def CreateLayout(self) :  
  
      self.SetTitle("test")  
        
      self.AddButton(1000, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, 0, 0, "Action")  
      self.AddButton(2000, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, 0, 0, "Close")  
  
      return True  
  
  def Command(self, id, msg) :  
  
      if id == 1000:  
          for i in xrange(100) :  
              time.sleep(.1)  
              print(i)  
              c4d.StatusSetBar(float(i))  
                
          c4d.StatusSetBar(float(-1))  
  
      if id == 2000:  
          self.Close()  
            
      return c4d.gui.GeDialog.Command(self, id, msg)   
  
def main() :  
  dialog = TestDialog()  
    
  dialog.Open(c4d.DLG_TYPE_MODAL_RESIZEABLE, 132456, -1 ,-1 ,400 ,400)  
  
if __name__=='__main__':  
  main()

I think there are some differences on both Mac and Windows in regards to GUI handling so I cannot guarantee that this works in any situation.

Best wishes,
Sebastian

Hello again, Sebastian.
I tried it and no Status Bar appears
And the Console output is only shown in the end of the cycle.
So, no updates during the cycle.
