Hi,guys.

I'm learning to create a simple dialog with python,but it is not working,I don't know how to solve the issue.could you help me? Any help would be greatly appreciated!

Here is the code below:

  
import c4d  
import os  
from c4d import gui  
  
  
id_1=1001  
  
class Layout(gui.GeDialog,) :  
  def CreateLayout(self) :  
        
      self.SetTitle("HDRI Created")  
      self.AddButton(id_1,c4d.BFH_CENTER,100,name='Hdri')  
        
      return True  
    
  def InitValues(self) :  
        
      self.SetBool(id_1,False)  
        
      return True  
    
  def Command(self,id,msg) :  
        
      if (id == id_1) :  
            
          sky = c4d.BaseObject(c4d.Osky)  
          sky.SetName("Relfect sky")  
            
          mat = c4d.BaseMaterial(c4d.Mmaterial)  
          mat.SetName("Reflection")  
          doc.InsertMaterial(mat)  
            
          tag = sky.MakeTag(c4d.Ttexture)  
          tag[c4d.TEXTURETAG_MATERIAL] = mat  
            
          doc.InsertObject(sky)  
            
          c4d.EventAdd()  
            
      return True  
            
            
def main() :  
  test = Layout()  
  test.Open(c4d.DLG_TYPE_MODAL_RESIZEABLE)  
  
if __name__=='__main__':  
  main()

Hi,

I'm sorry, but to everyone's advantage on this forum, can you please describe your problem and the expected results of posted code? This would help us immensely in order to focus on solving problems rather than looking for them.

Also I moved the thread into the Python sub-forum.

Hi,

just Andreas, please, that's enough.
The thing is you are using a modal dialog, which means, that C4D is basically sitting still in the background, while your dialog is open. That's also the reason the EventAdd() does not do, what you probably expect.
So, if you want to use a modal dialog, all scene changes will only be visible after the dialog gets closed. And that's also the point in code, where you should call EventAdd() in order to inform C4D about the changes and make them show up in for example Object Manager immediately.

Hi,Andreas.

Thank you for your reply.I'm very sorry, my English is poor. So far I didn't  understand the difference between two types of the dialogs,one is a modal dialog anther is a async dialog.would you mind explain this? Thank you !

Hi,

a modal or synchronous dialog blocks the execution of Cinema 4D in the background. As long as such a dialog is open, the user won't be able to interact with the rest of Cinema. Like for example, when you open the "Manage User Data..." dialog on any object in Attribute Manager. That's a modal diallog, C4D is blocked until the dialog gets closed.

The opposite is an asynchronous or non-modal dialog. Like for example the Object Manager, the Attribute Manager or the Preferences (the most dialogs in C4D are non-modal). While Preferences are open you can continue working with C4D and the dialog can stay open and be docked anywhere into the layout. Of course a non-modal dialog is slightly more complex, as you may need to care for the user changing things outside of your dialog (like adding/editing objects, switching to another scene...).
