Do not try to be too smart which compilations need config.h, as most of
them will simply because of the config.h has information about system
capabilities.
* a reasonable initial placement is important for later movements to
different heads and correct head detection (required by apps file)
* it did not work well in case when (0,0) was not near any head
* if you have e.g a 1920x1200 monitor and a small 800x600 monitor to the
right of the bigger one and a small window at the right side of the
big monitor (but still the whole window area at the big monitor) then
the original head detection would claim the window is on the small
monitor because (800/2+windowWidth/2 < 1920/2+windowWidth/2) is true
for small windows; but that is obviously wrong, the window is entirely
on the big monitor
* these incorrect head detections did lead to incorrect window
placements as they were required in the apps file
Commit 79fe2fca1d checks for pending
motion events and drops out of the FluxboxWindow::motionNotifyEvent() function
early if so. When the user does not use the opaque window movement method an
outline will be drawn to the screen. That outline was not cleaned correctly
with commit 79..
It's hard to hit right moment to update the clock correctly: Either we are a
bit too early and the 'old time' is the same as the 'new time' and the clock
looks 'a bit off' or we are too late and the clock is 'a bit off'. This is
especially the case for format strings which do not show the second and thus
are updated only at the full minute (see bug #1082): if fluxbox does not
update the clock 'now' it would do it one minute later and thus the clock
might show the wrong time for roughly 1 minute.
Instead of coming up with something immensely clever we just trigger the
ClockTool every second. If no update of the shown time is needed fluxbox won't
do anything.
Some minor code reordering as byproduct.
By removing FbTk/LogicCommands.o from LDADD in src/Makefile.am (commit
06655f6) I prevented the linker to pick up FbTk/LogicCommands.o and thus
rendered all logic-commands useless.
Using a small helper object to pull in the dependency fixes this problem
without relying on manually tweaking the build system.
First draft of feature request of #3602124: Having 2 buttons in the titlebar
which allow quick positioning of a Window into the left or right half of the
current monitor.
For odd 'widths' and 'heigths' the texture would not be filled completely:
Given a 'width' of 5 we would render only 4 instances of x (-2, 1, 0, 1)
instead of the needed 5. This results in a texture which looks a bit cut off
to the bottom right side.
std::set<Key, Comp> stores Key only if Comp(Key) yields a unique result (My
mistake: I was under the impression Comp is only used for the ordering). This
prevents FbTk::Timers with equal end-times from actually being started.
Escpecially in situation with multiple ClockTools this lead to stopped timers
(see bug #3600694).
Kudos to Adam Majer for enlightening discussions.
ClientPatterns might be tricky to get right. Instead of fiddling around in
either the keys-file or the apps-file and restarting fluxbox to see if the
changes had any effect / matched the right windows, 'ClientPatternTest' and
the fluxbox-remote should make this easier:
$> fluxbox-remote "clientpatterntest (title=.*vim*)"
This causes fluxbox to store the list of matched windows in the
_FLUXBOX_ACTION_RESULT property onto the rootwindow. This property might
then be read by:
$> xprop -root _FLUXBOX_ACTION_RESULT
or
$> fluxbox-remote result
The format of the list is:
win_id \t title_of_window \n
win_id is '-1' when fluxbox wasn't able to parse the given ClientPattern.
win_id is '0' when there are no windows matching the given ClientPattern.
Users expect time switches to happen upon system clock times. Calculating the
timeout for the next refresh of the shown time via the monotonic clock is
wrong: The monotonic clock yields values based upon some arbitrary point in
time which might be off a little bit to the system clock, a 'full' minute of
the monotonic clock might be in the midst of a system clock minute.
The old code did not brighten up "pure" colors like "red", "green" and "blue"
at all. The new code use a different precomputed LUT which is based upon
simplified vector math, see the comments in FbTk/ColorLUT.cc
* Calling Timer::setTimeout() from within Timer::start() might lead to ugly
behavior (as experienced in bugs #3590078, #3600143, etc; see commit
4d307dcd10, fixes the problem partially).
* Stop a timer first, then call the handler (via Timer::fireTimeout()). A
given handler might call Timer::start() again, which (re)adds the Timer
to the control list .. the following Timer::stop() would remove it again.
* Use 'm_start' as indicator if timer is running.
* Move the (now quite short) code of ::addTimer / ::removeTimer
into the Timer::start() and Timer::stop() functions.
Testing bits-per-pixel in the inner loop is suboptimal, especially since
that value does not change. A little helper macro helps to keep the code
readable, also improves the situation for StaticGray and PseudoColor.
With commit 541c8c4 we switched from an (manually) ordered list to a
std::set<> to handle the active timers. The code which checks for overdue
timers now traverses and modifies the std::set<> in place. This might
lead to an infinite loop. Examples of such bad behavior are "flickering of
the tooltip" (bug #3590078) or crashes (bug #3600143) or just insanely high
cpu load when autoraising windows or submenus.
We now make a copy of the std::set<> traverse this instead of the original.
In certain situations a speedy mouse might generate more move-events
than fluxbox can handle: The event queue will fill up faster than the
repositioning of the window is finished. The user will experience a
window which lags behind the mouse cursor, aka the window-dance.
We now check the next event in the queue and postpone the move a little
bit so the queue does not fill up that fast.
The changes made in b178bed60b used the wrong
variable to set the default state of '--enable-randr' in configure.in, that is fixed now. I
also removed '--enable-randr12': If support for the Xrandr-extension is
available at compile time we set HAVE_RANDR; if there is also support for
Xrandr-1.2 (or higher), we also set HAVE_RANDR1_2 automatically.
Other changes:
* cleaned out public interface of 'class Fluxbox'
* added 'RANDR' to output of 'fluxbox -info'
'filename' might contain a '~' which has to be expanded to work for
regular system calls. We expanded 'filename' already but then did not use
it. Fixes bug #3576586.
* reduced duplicated auto-code
* renamed '--enable-newwmspec' to '--enable-ewmh'
* don't compile 'Slit'-code when '--disable-slit'
* use AS_IF() in configure.in
* use AS_HELP_STRING() instead of obsolete AC_HELP_STRING in configure.in
* removed redundant calls to 'imlib2-config' to fill in $IMLIB2_CFLAGS
and $IMLIB2_LIBS, AC_PATH_GENERIC() does that out of the box already
* much more readable and easier to read code
* smaller code
* reduced binary size due to removed big lookup-table for square root
* simple 'optimizations (lookup tables, packing of data), nothing too fancy
Adding the following lines to the keys file restore the old behaviour to
use Mouse2 on tabs to start tabbing, and keep OnTitlebar Mouse2 to lower
the window.
OnTab Mouse2 :StartTabbing
OnTab Move1 :StartMoving
Note: Internal tabs are triggering both OnTab and OnTitlebar events.
The old formula for vertical align text inside FbTk::TextButton ('height/2 +
font_ascent/2 - 1') produced not always good looking results, escpecially
when different fonts are involved (eg, ClockTool and WorkspaceName have
different fonts and font-sizes).
'(height - font_ascent) / 2 - 1' produces better results.
Additional changes:
* added ASCII-Art to document the involved entities when calculating the
baseline
* rewritten tests/testFont.cc to accept multiples texts and multiple
fonts
* removed some internal parts of FbTk::Font from the public interface
Setting a new timeout on a running FbTk::Timer must remove it from the timerlist,
otherwise the list is not ordered correctly anymore. So, we stop the running
FbTk::Timer, set the new timeout and restart it.
gettimeofday() is subject to be changed on daylight-saving or to ntp-related
(think leap-seconds). even worse, it is subject to be changed BACK in time. this
is hard to fix correctly (see commit 45726d3016 and bug #3560509). it is
irrelevant for timers to know the nano-seconds since the epoch anyways.
When a screen has more heads and some part of the screen is not on any
head and some window is placed into this invisible area then the window
is invisible which sucks. This patch repositions such windows so that
they are visible.
Example:
* head 1 is at (0,120) (size 640x480)
* head 2 is at (480,0) (size 800x600)
* whole screen virtual size is 1440x600
* that means rectangle from (0,0) to (640,120) is not visible on any head
and any windows placed there would not be visible; for example wireshark
likes to place dialog boxes at (0,0)
Found with cppcheck:
"Prefix ++/-- operators should be preferred for non-primitive
types. Pre-increment/decrement can be more efficient than
post-increment/decrement. Post-increment/decrement usually
involves keeping a copy of the previous value around and adds
a little extra code."
Applications like urxvt look for the _MOTIF_WM_INFO atom in order
to know if the window manager implements mwm hints. If this atom
is not found, then urxvt sets override_redirect when started with
the borderless option and falls out of the control of Fluxbox.
if pos is not npos, it will always be less than filename.size().
However, the access later is only safe if there is a character
after pos, which would require pos + 1 to be less than filename.size.
