   1 Woop, a HACKING document for openbox at last!

   3 dirs:
   4         kernel - core of the WM
   5         render - librender, rendering routines for the WM and for apps
   6         cwmcc  - client-wm-client communication. netwm/icccm helper routines
   7                  for the WM and apps
   8         obcf   - openbox config format, generic parser for config files
   9         plugins - various plugins

  11 Beware the Client.transient_for. It can be set to a !NULL value of TRAN_GROUP,
  12 which is not a valid pointer. You must ALWAYS check for TRAN_GROUP before
  13 following transient_for. When TRAN_GROUP is found, Client.group will always
  14 be !NULL. Some smart action should be taken using all members of the group in
  15 this case.
  16     Smart action idea:
  17         Skip over members of the group that are also transients of the group
  18         (have Client.transient_for set to TRAN_GROUP). These windows are not
  19         ancestors and using them will also end up causing infinite loops!

  21 When using coordinates/sizes of windows, make sure you use the right area. The
  22 Client.area rect is the reference point and size of the *CLIENT* window. This
  23 value is not what you see in any shape or form, and gravity is applied to it to
  24 translate it into what you see. The Client.frame.area is the actual position
  25 and size of the entire frame. This is usually the value you want to use, unless
  26 you are in client.c (probably) and adjusting/using the position or size from
  27 the client's perspective.

  29 Indentation
  30 -----------
  31 For openbox, we aim to have consistent coding style. Some, but surely
  32 not all, guidelines:
  33  * use 4 space indents
  34  * tabs should not appear in source files
  35  * functions should have the opening and closing braces on their own
  36    lines
  37  * most other constructs should have braces on the same line as the
  38    statement
  39  * when in doubt look at the rest of the source
  40  * vim users can use "set expandtab tabstop=4 shiftwidth=4
  41    softtabstop=4" for some of this
