* Fix integer wrap around for some situations (resulting in a very wide
window):
w = max_width - x_offs - (*closest)->widthOffset()
If the given window is on the right most display and thus 'x_offs' is
bigger than 'max_width' (half of the display width), the resulting 'w' wraps
around and becomes very large.
* Place a single window via ArrangeWindowsStack* as well
* Some minor code styling / reordering along the way
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."
the previous version of operator*() made no sense. E.g., it violated the invariant
(*ptr).foo <=> ptr->foo. The dereferencing operator now returns a reference to the pointed-to
object, rather than a pointer to it.
I also added a bool conversion operator, which can be used in testing the NULL-ness of the
pointer. Anyone wondering if that could be done in a simpler way is encouraged to read
<http://www.artima.com/cppsource/safebool.html>.
And, finally, I removed the mutable flag from the m_data member, since it does not need it.
biggest change: renaming of 'class Layer' to 'class ResourceLayer' in
Layer.hh to handle complaints about 'ambiguous Layer: Layer or FbTk::Layer'.
'ResourceLayer' sounds crappy, but that was the best I could come
up with right now.
if the xkb-extension is enabled and the user switches between his/her
keyboardlayouts fluxbox's keybhandling doesn't work well anymore because
xkeyevent.state contains also xkb-related flags and thus we have to handle
that with caution.
KeyUtils now contain 'isolateModifierMask()' to really work only on the
modifiers. why not as part of cleanMods() ? because the XLookupString return
false results, eg TextBox's would only print chars from the first
keyboardlayout.
