Using an unspecified prototype function for a callback is calling
for problem. Added an explicit prototype for the 2 callback
functions in WDefaultEntry, and fixed the functions used to match
it. The new code should be a lot safer.

wMaximizeWindow() was previously rewritten and simplified.
Unfortunately the rewrite introduced a regression with windows which
were horizontally maximized or Maximusized, whereby they would be too
small after the maximization.
The bug is easy to see by opening a standard 80x24 terminal and hitting
the maximize horizontally shortcut. The terminal shrinks to 21 lines.
Pressing the shortcut key again correctly restores it to 80x24.
The fix is to refrain from shrinking the final window height, which is
done to account for its frame border and titlebar, for the affected
maximization styles.
Explicitly match a Return keypress in the switchpanel, so that the
currently selected window is focused without the keypress event being
handled elsewhere.
Pressing Return to commit the window selection is intuitive but other
shortcuts may bind Return. Any keypress not explicitly handled in the
switchpanel code will be passed through to other shortcut processing.
If, for example, alt+return were mapped to Select Window and the
switchpanel is open, pressing return while holding alt would both commit
the window change AND select the window, which is not intuitive.
If the new preference SwitchPanelOnlyOpen is set to YES, pressing
alt-tab or similar shortcut will only open the panel without
automatically switching to the next window. Shortcuts will continue to
function normally once the panel is open.
Users can enable the new preference if they find themselves regularly
opening the switchpanel just to visualise which windows are open, or to
initiate same-class cycling.
The default value of the new preference is NO. Behaviour is unchanged
unless the preference is explicitly enabled with the following command:
$ wdwrite WindowMaker SwitchPanelOnlyOpen YES
Keep an array of flags to remember if icons are supposed to be selected
and/or dimmed, and don't redraw any which are already in the correct
state.
Originally I didn't think the benefit of doing this was worth the effort
but future commits will call changeImage() more often so cutting down on
unnecessary redraws suddenly became more useful.
The Workspaces entry in the main menu allows to rename workspaces by
clicking on the workspace name while pressing the Ctrl key.
However since commit 63219247c6 ("Added shortcut to switch to last used workspace")
there is one more entry before the workspace name list, and that leads to
picking a wrong name to rename -- clicking on the first workspace asks to
rename the second workspace and so forth. Trying to rename the last workspace
leads to a segfault.
This happens because there is an explicit offset in the current code (- 2)
to account for the "non-workspace" entries in the menu. If one adds one
more entry that offset should be changed too (this is a prime example
of fragile code leading to bugs).
The file funcs.h is removed. A new file osdep.h is created to hold
the definition for all osdep_*c files.
The files .c has been adjusted to include the right header files,
removing funcs.h, including osdep.h.

If one or more icons were dimmed in the switchpanel because the user
used GroupNext/PrevKey, then an icon was selected with the mouse or the
Home or End keys, dimmed icons remained dim. That could be unintuitive
if the selected window was of a different class.
Instead we now always redraw all icons when highlighting a different
icon.
When cycling through windows in the switchpanel using the GroupNextKey
or GroupPrevKey shortcuts, dim the icons of windows which are of a
different WM_CLASS.
A while loop in StartWindozeCycle() was checking the value of the panel
pointer and setting a flag to break out of the loop if it were NULL.
The current iteration of the loop was allowed to continue, however, with
the result that the null pointer could be passed to one of the
switchpanel functions and cause a segfault.
To reproduce, close all windows except one. Open the inspector and set
the window's "Do not show in the switch panel" flag. Then close the
inspector and press alt-tab to open the switchpanel. As there is only
one window and it is not allowed to appear in the switchpanel, a null
panel pointer is returned, then later passed to wSwitchPanelSelectNext()
causing wmaker to crash.
The fix is to break out of the loop immediately instead of setting the
done flag.
new window positions top left, top right, bottom left and bottom right
these new maximized positions are combinations of left, right, top and
bottom maximized positions
if a window was at x=0 or y=0, the original condition return
false and the window is not moved to original position,
but if width or height from old_geometry is set then wmaker
already saved old_geometry, and we can trust x=0 or y=0 is
original position.
- remove extern declaration in source file, use header instead
- add inclusion of header defining the functions of the file to
get the compiler to cross-check them
- marked static the functions that should not be visible ouside
their file
This is the correct way to tell that a function takes no
arguments, because an empty parameter list tells the compiler
that it is not yet defined, and is tolerated only for
compatibility with very old C compilers for whom prototypes
were not yet a defined language element.
The functions are now grouped by source file (groups in alphabetic
order) with the traditional separation mark. This makes the file
easier to work with.
The equality comparison (a == b) is known to be a dangerous trap
when floating-point arithmetics are involved. In the current case
the offending operation can be done with integers directly.
Some header were creating variable, this is a bad practice which
is likely to not behave as expected. This creates one distinct
variable in each object file that used the header, and:
- on well behaved compiler, this ends up in a link error (see
commit 39fdb451ba for an example)
- on bad behaving compiler, this can be linked as multiple local
variable, thus having strange effects when running program
- on insouciant compiler (who said gcc?) the variables are
silently merged, hiding portability issues
Autoconf provides the necessary stuff to detect if inline keyword
is supported, and to detect special syntaxes, so let's use this
and remove the multiple local definitions, this makes code simpler.
When using the formula [sizeof(array) / sizeof( x )] to get the number
of element in a static array, it is better to use array[0] for 'x'
instead of the base type of array:
- in case the base type would change someday;
- if the compiler were deciding to insert padding somewhere
Considering the number of headers we have, it is a good idea to
avoid possible problems. For details, you may read:
http://en.wikipedia.org/wiki/Include_guard
All headers should be ok now.
The automake documentation states that using substitution inside the
list of SOURCES will not work and calls for not doing it. The use
of 'EXTRA_xxx' made things look like they worked but is probably not
enough for corner cases.
This patches switches to the conditional method which will be safe.
This patch includes info about XRandR extension in the info panel
dialog. If wmaker was compiled with xrandr support, then the dialog
show the XRandR info. The info includes if the X-Server supports or not
XRandR (wmaker could be compiled with XRandR support, but the X Server
may not include XRandR extension).
The string was separated in two by Christophe Curis to allow translation,
as suggested by Alexey I. Froloff.
The history is actually loaded from a file into a property list that
is then converted to an array. The intermediate property list was
not freed, which led to memory leak.
It looks like it was a tentative of optimisation to avoid duplicating
an already allocated string and re-use the pointer instead, but this
means it is not possible to free the original container as it would
free the string too.
There is a better way to do this, but it requires an API change on the
WUtil library so it is left for a future improvment.
The previous code limited the number of entries that were read into
the history array, but the user is expecting a maximum on the
number of entries displayed. This can make a little difference in
two cases:
- if there are duplicate entries (dups are checked for and removed)
- if some entries are not strings (unlikely, but not impossible)
The new code just stops adding history entries when the user
specified count is reached.
When menus are read in the PropList format, they are loaded into a
temporary PropList object, which is parsed into the internal menu
structure, and the PropList object is no more used. There were two
cases where this temp object was not freed.
If the switchpanel was opened with either FocusNextKey or FocusPrevKey
shortcut, and the user presses GroupNextKey or GroupPrevKey, skip over
windows of a different class when cycling through windows in the
switchpanel.
In the case where the switchpanel was opened with FocusNextKey or
FocusPrevKey initially, the check can be skipped because all the
available choices are necessarily of the same class already.
