/* 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 ", 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.
