Issue with Separators in "ShowPopupDialog"[SOLVED]

Hello fellow programmers,

I want to add a number of separators for a popup menu that I'm implementing in order to group the menu into different sections.
The first separator shows up fine, but the next one is omitted. Not sure if this is just a limit of the PopupDialog or if I'm doing something wrong.

Example code as follows:

import c4d
  
def main() :
    bc = c4d.BaseContainer()
    bc.SetString(c4d.FIRST_POPUP_ID+5, "Popup Menu 1...")
    bc.SetString(c4d.FIRST_POPUP_ID+1, "Popup Menu 2...")
    bc.SetString(c4d.FIRST_POPUP_ID+2, "Popup Menu 3...")
    bc.SetString(0, "") 
    bc.SetString(c4d.FIRST_POPUP_ID+3, "Popup Menu 4...")
    bc.SetString(0, "") 
    bc.SetString(c4d.FIRST_POPUP_ID+4, "Popup Menu 5...")
    bc.SetString(c4d.FIRST_POPUP_ID, "Popup Menu 6...")
    
    result = c4d.gui.ShowPopupDialog(cd=None, bc=bc, x = c4d.MOUSEPOS, y = c4d.MOUSEPOS, flags = c4d.POPUP_CENTERHORIZ) - c4d.FIRST_POPUP_ID
    
  
if __name__=='__main__':
    main()

Like I said, the separator after "Popup Menu 3..." shows up but the next one doesn't.
Hopefully someone can clarify the situation.

Thanks

Hello,

you are calling SetString(0, "") twice. This will do the same thing twice: storing an empty string at ID 0. So the second time when you call SetString(0, "") you are just overwriting the existing entry, you are not adding anything.

You can add an element to a BaseContainer using InsData () which will add an element independent of the given ID. It is probably recommended to use InsData () with such BaseContainers.

  
bc = c4d.BaseContainer()  
bc.InsData(c4d.FIRST_POPUP_ID+1, "Popup Menu 1...")  
bc.InsData(0, "")   
bc.InsData(c4d.FIRST_POPUP_ID+2, "Popup Menu 2...")  
bc.InsData(0, "")   
bc.InsData(c4d.FIRST_POPUP_ID+3, "Popup Menu 3...")  

best wishes,
Sebastian

Hi Sebastian, thank you for the help! This works perfectly, even though I have to admit that I still don't fully understand how BaseContainers function.
If BaseContainer takes the data sequentially, shouldn't the second separator (overwriting the first one) be the one that shows up? What is InsData doing differently, so that the IDs don't get overwritten?

Guess I have to look more into the technicalities of that class.

Hello,

SetString() and InsData() are two different functions that do two different things. SetString() would overwrite an element with the given ID. InsData() adds another element with the given ID:

  
bc = c4d.BaseContainer()  
  
bc.SetString(0, "Some String A")  
bc.SetString(0, "Some String A")  
  
print("Print Elements:")  
  
for element in bc:  
  print(element)  
  
bc.FlushAll()  
  
bc.InsData(0, "Some String B")  
bc.InsData(0, "Some String B")  
  
print("Print Elements:")  
  
for element in bc:  
  print(element)

Hi Sebastian,
thank you for clearing that up. Initially i thought BaseContainers worked like a dictionary, with the indices being the keys. Apparently it is more like a list, with the get/set methods using it as a quasi dictionary.
What I noticed though, is that the get/set methods only take the first occurrence of any index into account.

import c4d
  
bc = c4d.BaseContainer()
  
bc.InsData(0, "Some String")
bc.InsData(0, "Some String")
bc.SetString(0, "Some New String")
  
print("Print Elements:")
  
for element in bc:
    print(element)
    
print bc.GetString(0) 

In any case, my initial question was fully answered and i feel a little smarter now. :slightly_smiling_face:
Thanks for your help.

Best
