in some cases, it's possible for a client which expects to render on
the next frame to actually render on the frame after. in these cases,
the compositor must not clear the pixmap image until after the render
has occurred in order to avoid inaccuracies. for this reason, the best
place to flag a client for post-render work is at the time of the client's
render
ref T2762
ref D3120
if this isn't explicitly blocked by config options then allowing resizes
on the unmaximized axes is necessary in order to avoid accidentally
queuing a full unmaximize
this is unmaintained and out of date. the protocol versions are old,
and it's extremely unlikely that any client will work and be in a
usable state given the development progress since E19 was originally
released.
use E20+ for wayland support.
fix T2746
according to ICCCM 4.1.4:
Only the client can effect a transition into or out of the Withdrawn state
withdrawn windows cannot be shown under any circumstances. the best that can
be done is to try mapping the window and hope it decides to appear.
to prevent any inadvertent showing of the window before it leaves the
withdrawn state, we play games with the E_Client->ignored flag in order
to skip client evals until we get notified that maybe we want to stop
skipping those evals
ref T2745
also includes 0e3cc2f533
gtk apps set an atom which provides information about the area
where non-window content (eg. shadows) may be drawn; this area
must not be used in placement calculations.
the easiest method for implementing this functionality was to add
a case to the compositor geometry interceptors which effectively
flip the client struct geometry values such that the E_Client->client
is outside of the more commonly used E_Client->x/y/w/h
fix T2744
this is not actually supported yet, so behavior of windows using this
feature will be more wayland-like, eg. geometry determined by area
of window+shadow
fix T2744
add deskmirror refs to avoid segv on shutdown/restart due to mb->m
becoming a pointer to freed (now garbage) memory, so trace every
ref/unref and count them to get it right. crash gone!
resolves issue where setting a specific kbd would fail to make settings permanent
as well as not propagating the kbd change to the rest of enlightenment
fix T1810
somehow it was possible for client sizes to overflow the zone geometry here
which would end up breaking maximization limits and result in clients
not respecting various geometry boundaries
this should fix open file handles on unmount by flushing caches first.
not great, but works. long-term have evas not keep file handles open
for 0 refcount cached items.
focusing a client will automatically uniconify and desk flip, so
setting focus on a hidden client should be avoided during eval since
these focus-sets are not "user triggered"
this fixes issues where clients could randomly grab focus from other
desks and also restores expected behavior when restarting e on an
empty vdesk
when using "system" backlight mode, ensure that events are processed
as they occur so that the available backlight level is in sync with
the actual backlight level
fix T2255
due to the presence of color classes on internal windows, e must
ensure that users who set translucent colors for window base objects
get transparency as expected on those parts of the window. it's impossible
to determine in advance whether alpha is needed, so it's best to just
set alpha in all cases
fix T2050
ilist widget adds items in a deferred queue, resulting in attempts to
immediately toggle the disabled state having no effect. now there is
a flag so that items added after the disabled flag have been set will
have the correct state
fix T2730
in the case where a window is fullscreen without having the 'fullscreen'
flag set, the previously-used layer must be reapplied upon nocomp end
in order to avoid breaking the compositor
as a result of earlier changes which prevented recursive desk flips,
e_desk_show() now rejects some desk show calls which are invalid such as
a show where the "current" desk does not have the visible flag set. this
behavior is overridden in the case of startup, which is functionally the
same effect as changing the desk count
fix T2717
if windows set to "Always on Top" exist while the option to allow
windows over fullscreen windows is enabled, enabling nocomp will
result in the above windows being stuck over the nocomp window
instead, force the nocomp window to be the top-most window in all cases,
and then put it back if another object appears on the screen over it
fix T2703
when a client is set to "Always on Top", it will be on the same layer
as override clients. this can cause strange stacking and mouse eventing
in cases where these windows occupy the same space and the normal client
is stacked over the override
this prevents an infinite focus loop where focus will be constantly
reapplied between multiple windows if the activated window is not the
refocus window
it seems that since the first version of the enlightenment compositor
in e17, damage events in x11 have never been used correctly. using
the event struct members will only give the bounding box/area instead
of the damaged regions; the real regions must be explicitly fetched
from the server
this removes the need for a lot of hacks which were added over the years
to make override windows render correctly, and also probably reduces
rendering overhead slightly
if another callback triggered the creation of a deskmirror visual while
the dirty callback was in place, a second mirror object would be created
leading to an orphaned mirror object which retained references to the dm
client and eventually resulting in a crash
the currently visible desk for a zone is stored on the zone struct, so
iterating here is unnecessary. furthermore, at the time when a desk is hidden,
a client may begin receiving mouse events which could trigger a focus-set and
lead to another desk flip. at this time and only this time, the "current" desk
will be marked as not visible, and so this sort of desk show must be rejected
fix T2676
in the case that the canvas window has just had focus set on it, apply this focus
and ensure that no client retains focus
this resolves a race condition where focusing the compositor canvas <-> client
extremely quickly would result in a client trying to steal focus when it was
not actually focused
a notable (but trivial) side effect is that now when flipping desks at high speed while using
mouse-based focus policies, the user is almost guaranteed to end on a desk which
has open windows on it
in the case of recursive desk flips, toggling a desk's visibility may
erroneously send queued evas events to the client's frame object, leading
to a focus-set (mouse-based focus models) which triggers a desk flip
inside the original desk flip. this "inner" desk flip is spurious and
should be ignored
it seems that the reported damage events upon resizing an override window
are not accurate, and so we must force a full damage here while avoiding a
render queue in order to ensure that the full contents of the override will
be rendered in the next frame
fix T2045
this seems to fix an extremely rare issue related to both deskmirror artifacts
and crashes in deskmirror during restart; I was only able to reproduce the crash
twice in the span of over an hour of testing and it seemed to disappear after
this change
deferred focus should no longer be valid if a client has been hidden
before the focus-set could be triggered
fixes super fun infinite loop with desk flips
it seems that some changes now make the shel menu post callback be
called for older menus not part of the shelf and thus shelf menu
stored != menu the cb is for - thus resulting in deletion of the wrong
menu
this has been in e for ages - someone not noticed, but this fixes
visual artifacts of left over menus on the top-left. this extra ref
really makes no sense. it's not like this ref is then accomoanied by a
matching unref somewhere else (after much debugging).
@fix
in the case that a client is going to be shown on the next loop iteration,
focus setting must still occur and be deferred
this fixes the case of a window appearing on a desk while the user is switching
desks away from it even though this window is attempting to focus itself
