* src/*.[ch]: Stick an emacs comment directive at the beginning of
all the code files so that people using emacs will be more likely
to get coding style correct in their patches. We still need a
similar vi directive. #358866
2006-03-16 Elijah Newren <newren gmail com>
Add debugging information for edge resistance
* src/edge-resistance.c (cache_edges): print out the edges that
are being cached if in verbose mode,
(meta_window_edge_resistance_for_move,
meta_window_edge_resistance_for_resize): if edge resistance kicked
in then print out a message about it
* src/util.c:
* src/util.h:
Add META_DEBUG_EDGE_RESISTANCE to MetaDebugTopic enum list

Merge of all the changes on the constraints_experiments branch.
This is just a summary, to get the full ChangeLog of those
changes (approx. 2000 lines):
cvs -q -z3 update -Pd -r constraints_experiments
cvs -q -z3 diff -pu -r CONSTRAINTS_EXPERIMENTS_BRANCHPOINT ChangeLog
Bugs fixed:
unfiled - constraints.c is overly complicated[1]
unfiled - constraints.c is not robust when all constraints
cannot simultaneously be met (constraints need to be
prioritized)
unfiled - keep-titlebar-onscreen constraint is decoration
unaware (since get_outermost_onscreen_positions()
forgets to include decorations)
unfiled - keyboard snap-moving and snap-resizing snap to hidden
edges
109553 - gravity w/ simultaneous move & resize doesn't work
113601 - maximize vertical and horizontal should toggle and be
constrained
122196 - windows show up under vertical panels
122670 - jerky/random resizing of window via keyboard[2]
124582 - keyboard and mouse snap-resizing and snap-moving
erroneously moves the window multidimensionally
136307 - don't allow apps to resize themselves off the screen
(*cough* filechooser *cough*)
142016, 143784 - windows should not span multiple xineramas
unless placed there by the user
143145 - clamp new windows to screensize and force them
onscreen, if they'll fit
144126 - Handle pathological strut lists sanely[3]
149867 - fixed aspect ratio windows are difficult to resize[4]
152898 - make screen edges consistent; allow easy slamming of
windows into the left, right, and bottom edges of the
screen too.
154706 - bouncing weirdness at screen edge with keyboard moving
or resizing
156699 - avoid struts when placing windows, if possible (nasty
a11y blocker)
302456 - dragging offscreen too restrictive
304857 - wireframe moving off the top of the screen is misleading
308521 - make uni-directional resizing easier with
alt-middle-drag and prevent the occasional super
annoying resize-the-wrong-side(s) behavior
312007 - snap-resize moves windows with a minimum size
constraint
312104 - resizing the top of a window can cause the bottom to
grow
319351 - don't instantly snap on mouse-move-snapping, remove
braindeadedness of having order of releasing shift and
releasing button press matter so much
[1] fixed in my opinion, anyway.
[2] Actually, it's not totally fixed--it's just annoying
instead of almost completely unusable. Matthias had a
suggestion that may fix the remainder of the problems (see
http://tinyurl.com/bwzuu).
[3] This bug was originally about not-quite-so-pathological
cases but was left open for the worse cases. The code from
the branch handles the remainder of the cases mentioned in
this bug.
[4] Actually, although it's far better there's still some minor
issues left: a slight drift that's only noticeable after
lots of resizing, and potential problems with partially
onscreen constraints due to not clearing any
fixed_directions flags (aspect ratio windows get resized in
both directions and thus aren't fixed in one of them)
New feature:
81704 - edge resistance for user move and resize operations;
in particular 3 different kinds of resistance are
implemented:
Pixel-Distance: window movement is resisted when it
aligns with an edge unless the movement is greater than
a threshold number of pixels
Timeout: window movement past an edge is prevented until
a certain amount of time has elapsed during the
operation since the first request to move it past that
edge
Keyboard-Buildup: when moving or resizing with the
keyboard, once a window is aligned with a certain edge
it cannot move past until the correct direction has
been pressed enough times (e.g. 2 or 3 times)
Major changes:
- constraints.c has been rewritten; very few lines of code from
the old version remain. There is a comment near the top of
the function explaining the basics of how the new framework
works. A more detailed explanation can be found in
doc/how-constraints-works.txt
- edge-resistance.[ch] are new files implementing edge-resistance.
- boxes.[ch] are new files containing low-level error-prone
functions used heavily in constraints.c and edge-resistance.c,
among various places throughout the code. testboxes.c
contains a thorough testsuite for the boxes.[ch] functions
compiled into a program, testboxes.
- meta_window_move_resize_internal() *must* be told the gravity
of the associated operation (if it's just a move operation,
the gravity will be ignored, but for resize and move+resize
the correct value is needed)
- the craziness of different values that
meta_window_move_resize_internal() accepts has been documented
in a large comment at the beginning of the function. It may
be possible to clean this up some, but until then things will
remain as they were before--caller beware.
- screen and xinerama usable areas (i.e. places not covered by
e.g. panels) are cached in the workspace now, as are the
screen and xinerama edges. These get updated with the
workarea in src/workspace.c:ensure_work_areas_validated()

Truncate ridiculously long titles to avoid crashing or letting the
pager crash. Based on patch from Ray, incorporating suggestions
from Havoc and some extensions of my own. Fixes#315070.
* src/display.c (set_utf8_string_hint, meta_display_open):
* src/xprops.[ch] (meta_prop_set_utf8_string_hint):
Move set_utf8_string_hint() to props.[ch], namespace it
("meta_prop_"), and make it public

* src/util.[ch] (meta_g_utf8_strndup):
Move utf8_strndup() to util.[ch], namespace it ("meta_g_"), and

length is greater than 512, truncate it and set
_NET_WM_VISIBLE_NAME or _NET_WM_VISIBLE_ICON_NAME accordingly
2003-12-25 Havoc Pennington <hp@redhat.com>
* src/compositor.c (meta_compositor_process_event): change to
track all children of the root window, not only mapped children;
this keeps us from losing track of the stacking order

extension, instead of just using it all over the place.
* src/prefs.c (update_application_based): don't let people turn on
application_based, as it just causes funky bugs. We can reenable
the pref when/if it ever does something useful.

Optimizations for managing new windows (do not all take effect if

Throughout: move to new error trap setup to save on XSync calls,
new setup is:

sync even if an outer trap still exists

* src/metacity.schemas: add schemas for all the keybindings.
* src/window.c (meta_window_activate): if in "show desktop" mode
when a window is activated, leave show desktop mode. So e.g.
when you click on a task in the task list, show desktop mode
will be turned off.

that doesn't quite work yet (needs support for getting
workspace layout from the pager)
* src/prefs.c: keybindings stuff

of to ~/metacity.log.
2002-03-02 Havoc Pennington <hp@pobox.com>
* src/display.c: Add hacking to fix the problem that we made our
XGrabPointer() during Alt+Tab actually succeed, so on popping down
Alt+Tab we got an EnterNotify from the ungrab, which resulted in
focusing the window under the mouse. i.e. Alt+Tab didn't work with
sloppy focus.
2002-02-07 Havoc Pennington <hp@pobox.com>

switching to a new workspace

didn't free tab list

or unmanage a focused window
* src/stack.c (meta_stack_get_default_focus_window): function used
in meta_screen_focus_top_window
2001-09-10 Havoc Pennington <hp@pobox.com>
* src/window.c: Don't separate user_has_moved/user_has_resized,
fixes bug in east-resizing Emacs, among other things

nothing to do
