version 1.0 ?
- From: Julian Adams <julian adams gmx net>
- To: wm-spec-list gnome org, Havoc Pennington <hp redhat com>
- Subject: version 1.0 ?
- Date: Wed, 22 Nov 2000 22:07:56 +0000
-----BEGIN PGP SIGNED MESSAGE-----
hi all -
I've commited a new version of the spec to CVS :)
Havoc could you regenerate the html and ps version on the website, please.
This version contains:
David's comments (thanks David!)
Sasha revisions to the window gravity stuff (unless somebody finds that it's
incorrect)
UTF-8 = RFC 2279 reference
X style copyright - copied from ICCCM
Revision -> 1.0 !
I hope this can be accepted as 1.0 as I think we're reached agreement on the
core, and I don't think delay will help us any. If not I can drop the version
back to pre-whatever. Otherwise it's smiles all round.
I haven't added any form of stays on top as:
a) there is no agreement (I hope we can agree on that, at least)
b) the spec doesn't deal with layering in any way. This is all bound up with
issues like staysOnTop, and is contentious to say the least.
diff is at the end of the email.
break out the fizzy pop ?
later -

< <title>Window Movement</title>
< <para>
< Window manager implementors should refer to the ICCCM for definitive
< specifications of how to handle MapRequest and ConfigureRequest events.
< However, since these aspects of the ICCCM are easily misread, this

< <listitem><para>
< Window managers MUST honour the win_gravity field of WM_NORMAL_HINTS
< for both MapRequest _and_ ConfigureRequest events [1]
< </para></listitem>
< <listitem><para>
< Applications are free to change their win_gravity setting at any time
< </para>
< <para>
< If application changes its gravity then Window manager should adjust the
< reference point, so that client window will not move as the result.
< For example if client's gravity was NorthWestGravity and reference point
< was
< at the top-left corner of the frame window, then after change of gravity to
< the SouthEast reference point should be adjusted to point to the
< lower-right
< corner of the frame.
< </para></listitem>
< <listitem><para>
< When generating synthetic ConfigureNotify events, the position given
< MUST be the top-left corner of the client window in relation to the
< origin of the root window (i.e., ignoring win_gravity) [2]
< </para></listitem>
< <listitem><para>
< XMoveWindow( w, x, y) behaviour depends on the window gravity:
< </para>
< <para>
< StaticGravity:

< </para></listitem>
< <listitem><para>
< Implementation Note for Application developers:
< </para>
< <para>
< When client window is resized - its reference point does not move.
< So for example if window has SouthEastGravity and it is resized -
< the bottom-right corner of its frame will not move but instead
< top-left corner will be adjusted by the difference in size.
< </para></listitem>
< <listitem><para>
< Implementation Note for WM developers :
< </para>
< <para>
< when calculating reference point at the time of initial placement -
< initial window's width should be taken into consideration, as if it
< was the frame for this window.
