Regexp for excluding line containing string from rest of the regexp

I have bunch of strings like:

object field: TMemo
  Left = 6
  Top = 23
  Width = 390
  Height = 156
  Anchors = [akLeft, akTop, akRight, akBottom]
  ScrollBars = ssVertical
  TabOrder = 1
  OnChange = fieldChange
  OnKeyUp = fieldKeyUp
  AddMenu = True
  RightClickMoveCaret = True
  RightEdge = 0
end

Or 

object btn: TButton
  Left = 5
  Top = 3
  Width = 89
  Height = 21
  Caption = 'Button'
  TabOrder = 0
  TabStop = False
  OnClick = btnClick
end

I want to select all text except name of object (in this case field and btn) and every line that starts with [space][space]On.

I can select everything without name of field using regexp like this: 

(object)|(: .*)|(end)|(  .*)

But I'm not able deselect lines starting with "On". Can you help me join my regexp with this regexp excluding this lines I want from selection?:

(^(?:(?!  On).)*$)

You could use a negative lookahead (?! On)( .*) for the last alternation to check what is on the right is not 2 spaces followed by On:

(object)|(: .*)|(end)|(?!  On)(  .*)

Regex demo

Since your matches are at the start and the end of the stirng, a more precise match might be using anchors ^ and $:

^(object)|(: .*)$|^(end)$|^(?!  On)(  .*)

Regex demo

Note that you can also get the matches without using capturing groups:

^object|: .*$|^end$|^(?!  On)  .*

Try this regex (maybe)

^(?!On.*$).*
