Problems with Edit Slider

Hi,

When I assign a value in InitValues(self) for an EditSlider, I can't use the slider anymore (it stays at the same value). So when I try to get the value it doesn't work, because the slider can't be edited.

I've followed the Python SDK instructions, but I'm not getting any further.
Are there special things I have to do to make it work?

Greetings,

Casimir

And when I don't assign a value in the SetReal, I can use the slider and get information out of it.

Not relates to your problem, but you will have problems if you store L_Foot globally. Better store it somewhere else than the global scope (eg from where you call AddLeftFoot(), and return L_Foot in this function)

Ditto what Nik said.
It's ok to use globals in C4D plugins. But try not to get carried away with them.
Put those kinds of values into your methods parameters whenever possible. It will be less confusing later on.

The reason you're having trouble with your slider is because the main GeDialog needs an instance of the subdialog in it so it can talk to the sub dialog properly.

Here's an example how to set up the dialogs:

import c4d  
import os  
import sys  
from c4d import gui, plugins, bitmaps, documents, utils  
  
PLUGIN_ID = 1000003 # Test ID  
  
GroupFoot = 2000  
FOOT_X_TEXT = 1000  
FOOT_X_SLIDER = 1001  
  
###### The sub dialog ######  
class InitializeSubDialog(gui.GeDialog) :       #<--You don't need to use "subdialog" ...It can just be another GeDialog  
  
  def CreateLayout(self) :  
      self.SetTitle("Character Values")  
        
      #Group Foot  
      self.GroupBegin(GroupFoot, c4d.BFH_SCALEFIT, 2, 0, "Foot")  
      self.GroupBorderSpace(5, 5, 5, 5)  
      self.GroupBorder(c4d.BORDER_GROUP_IN)  
      self.AddStaticText(FOOT_X_TEXT, c4d.BFH_LEFT, 0, 0, "Foot_X", 0)  
      self.AddEditSlider(FOOT_X_SLIDER, c4d.BFH_SCALEFIT, 500, 0)  
      self.GroupEnd()  
       
      return True  
   
  
  def InitValues(self) :  
  
      self.SetReal(id = FOOT_X_SLIDER, value = 5.0, min = 5.0, max = 20.0, step = 1.0, format = c4d.FORMAT_METER)  
      return True  
  
  def Command(self, id, msg) :  
      if (id == FOOT_X_SLIDER) :  
          print self.GetReal(FOOT_X_SLIDER)   #Print the value of the slider  
       
      return True  
  
  
###### The main dialog ######  
class InitializeDialog(gui.GeDialog) :  
  
  subdlg = InitializeSubDialog()       #The sub dialog's local class member instance <--- Very important!!!!!  
  
  def CreateLayout(self) :  
      self.SetTitle("Character Creator")  
  
      self.AddStaticText(0, c4d.BFH_CENTER, 0, 0, "GENDER", 0)

      return True  
  
  
  def Command(self, id, msg) :  
       
      if (id == 10002) :           #Button Create Character  
          GENDER = self.GetLong(10001)  
          print GENDER  
          doc = c4d.documents.GetActiveDocument()          
          self.subdlg.Open(dlgtype = c4d.DLG_TYPE_ASYNC, defaultw = 500, defaulth = 600)

Thanks for saying where to store my variables, still having a bit trouble with python variables, im more used with C++. And how do you mean, not relates to your problem?
I really have no clue how to get that slider good.

You have to pass a float to GeDialog.SetReal() as the value parameter. None won't work.
I think that is breaking the slider. You also did not implement RestoreLayout() despite the
fact that you did instantiate a non modal dialog which will generally end in a mess.

You should also always implement object.__int__() for each class. also use constantly self.
Both things are not mandatory but are considered as good style for a reason.
