Subject: Big changes to placement across multiple monitors.
X-Git-Tag: release-3.5.0~41
X-Git-Url: http://git.openbox.org/?p=dana%2Fopenbox.git;a=commitdiff_plain;h=95535e86237e6c89935eb7563f37f13474c466f2

Big changes to placement across multiple monitors.

Add a Primary option for which monitor to place new windows on.  Make "Active" the default instead of "Any", which is just totally crazy.

When a window is being placed in the FOREGROUND, use a monitor chosen in
  the following order:
  1. same monitor as parent
  2. primary monitor if placement=PRIMARY
     active monitor if placement=ACTIVE
     pointer monitor if placement=MOUSE
  3. primary monitor
  4. other monitors where the window has group members on the same desktop
  5. other monitors where the window has group members on other desktops
  6. other monitors

When a window is being placed in the BACKGROUND, use a monitor chosen in the
  following order:
  1. same monitor as parent
  2. other monitors where the window has group members on the same desktop
   2a. primary monitor in this set
   2b. other monitors in this set
  3. other monitors where the window has group members on other desktops
   3a. primary monitor in this set
   3b. other monitors in this set
  4. other monitors
   4a. primary monitor in this set
   4b. other monitors in this set

Decide to focus the new window before placing it, so we know if it will be
  placed in the foreground or background.

Always choose a single monitor, then place on it, rather than possibly moving
  to a "backup" monitor.  Unpredictable monitor placement is horrible.
