[python] SetFont not working

iluxa7k

Hello
C4D version: 20.059
OS: Windows 10

I select motext and try to change font(fontdata) for text by script

import c4d
from c4d import plugins
def main() :
  bc = c4d.BaseContainer()
  bc.SetString(500, 'Arial')
  bc.SetString(501, '11')
  bc.SetInt32(502, 400)
  bc.SetInt32(503, 0)
  bc.SetString(509, 'Arial')
  bc.SetString(508, 'ArialMT')
  # select mograph text
  op[c4d.PRIM_TEXT_FONT].SetFont(bc)
  op.Message(c4d.MSG_CHANGE)
  c4d.EventAdd()
if __name__=='__main__':
  main()

can not get it work

Found such solution:

import c4d

def main():

    bc = c4d.BaseContainer()
    ids = c4d.PRIM_TEXT_FONT
    #ids = c4d.DescID(c4d.DescLevel(2117,1009372,5178))
    op.SetParameter(ids, bc, c4d.DESCFLAGS_SET_0)
    bc.SetString(500, 'Arial')
    bc.SetString(501, '11')
    bc.SetInt32(502, 400)
    bc.SetInt32(503, 0)
    bc.SetString(509, 'Arial')
    bc.SetString(508, 'ArialMT')
    new_fd = c4d.FontData()
    new_fd.SetFont(bc)
    op.SetParameter(ids, new_fd, c4d.DESCFLAGS_SET_0)    
    c4d.SendCoreMessage(c4d.COREMSG_CINEMA, c4d.BaseContainer(c4d.COREMSG_CINEMA_FORCE_AM_UPDATE))
    c4d.gui.GeUpdateUI()
    c4d.EventAdd()

# Execute main()
if __name__=='__main__':
    main()

The issue you figured out is pretty common in python. So actually when you do op[c4d.PRIM_TEXT_FONT] (aka GetParameter) you retrieve a copy of this CustomDataType. That means if you want to modify something it will not be reflected in the UI.

Finally, you don't need all the update code only a c4d.EventAdd is enough.

import c4d

def main():
    # Retrieves a copy of the actual FontData
    fontData = op[c4d.PRIM_TEXT_FONT]
    
    # Defines parameters for this FontData
    bc = c4d.BaseContainer()
    bc.SetString(500, 'Arial')
    bc.SetString(501, '11')
    bc.SetInt32(502, 400)
    bc.SetInt32(503, 0)
    bc.SetString(509, 'Arial')
    bc.SetString(508, 'ArialMT')
    fontData.SetFont(bc)
    
    # Push back this FontData into the object
    op[c4d.PRIM_TEXT_FONT] = fontData
    
    # Pushes an update event to Cinema 4D
    c4d.EventAdd()

# Execute main()
if __name__=='__main__':
    main()

Cheers,
Maxime.

Hello Maxime
Thank you.
I tried such form and can not get it work. I think i'm "messing"(replace FontData to BaseContainer) data for GUI, so it does not work for me.

In which version are you? The code I posted is working nicely in R20.059.
