Adding labels to shape groups

[Abe Whaanga]

does anyone know how I might add labels to shape groups via a python script?  I have a script that creates a bunch of default shape groups, but I want the labels for everything in these shape groups to match the group name.

Hello Abe,

Do you mean to add the label to every shape in the group that corresponds to the group name?

Hi Alexey,

Yes every shape in the group that gets drawn needs to have a label that is the same as the group name.  My script below creates the default shape groups.


   current_document = Metashape.app.document
   current_chunk = current_document.chunk
   
   default_shp_groups = {'QV Maj':[255,0,0], 'QV Min':[255,0,0], 'FAULT':[38,0,255],'AN':[0,170,0], 'CHL':[0,0,0], 'BM':[0,0,0], 'CL':[0,170,255], 'COR':[0,85,0], 'INE':[255,85,0], 'BND':[0,0,0], 'BX':[0,0,0], 'MAS':[0,0,0], 'OX':[255,85,0], 'pd':[0,0,0], 'stk':[255,0,0] }

   #loop new groups to add
   for new_shp_group_key in default_shp_groups:
   
      #set test if group to be added already exists to False
      new_shp_group_key_exists = False
   
      #loop existing groups
      for existing_shp_group in current_chunk.shapes.groups:
      
         #test if new group to be added already exists      
         if new_shp_group_key == existing_shp_group.label:
            new_shp_group_key_exists = True
   
      if new_shp_group_key_exists == False:   
         new_group = current_chunk.shapes.addGroup()
         new_group.label = new_shp_group_key
         new_group.color = (default_shp_groups[new_shp_group_key][0], default_shp_groups[new_shp_group_key][1], default_shp_groups[new_shp_group_key][2])

Hello Abe,

You can assign the shape labels after their are drawn according to the layer labels in the following way:

Code: [Select]

for shape in chunk.shapes:
    if not shape.label:
         shape.label = shape.group.label

Thanks Alexey works great
