/*
testqtargs -- is there really a bug in KCmdLineArgs or am I on crack?
I used the following compile options:
g++ -g -Wall -o testqtargs testqtargs.cpp -I/usr/X11R6/include \
-I/opt/qt3/include -I/opt/trinity/include -L/usr/X11R6/lib -L/opt/qt3/lib \
-L/opt/trinity/lib -lqt -ltdecore
if invoked like this ./testqtargs --bg blue --caption something --hello hi
The program should list argv[] then produce output like this:
qt arg[0] = background
qt arg[1] = blue
arg bg = blue
arg caption = something
arg hello = hi
Instead for me it prints:
qt arg[0] = -background
qt arg[1] = blue
arg caption = something
arg hello = hi
See the extra dash in qt arg[0]? I believe that is the cause of the problem.
--bg is aliased to --background but If you try it with --background or
-background, you get the same thing.
in tdecore/kapplication.cpp, KCmdLineOption qt_options is defined and used
by the static method Kapplication::addCmdLineOptions to add the Qt options
but its' entries look like this:
{ "background <color>", I18N_NOOP("sets the default background color and an\n
application palette (light and dark shades are\ncalculated)."), 0},
it looks for "background" instead of "-background" so never find the arg.
Software: g++ 2.95, tdelibs from CVS Jan 28, Qt 3.01
