adding appications

Example application: example

Where possible, we store our stuff in a separate subdirectory smartclient

/usr/share/applications/example.desktop	general application description, like Name, Exec(utable), Icon. SmartClient subdirectory /usr/share/applications/smartclient/ would by possible, but %suse_update_desktop_file does not support directories
/usr/share/pixmap/example.png	application icon (using /usr/share/icons/default.kde4/48x48/apps/example.png is also possible, but more complicated. Also problems occur, if the user changes the default icon them)
/usr/share/mime/packages/example-mime-type.xml	mime type description

testing KDE4 icons

to test, if an icon is recognised by the system, act as follow:

# copy the icon example.png or example.svgz to /usr/share/pixmap/
# if available, choose the svgz image format, otherwise png. (xpm does also work)
cp -a example.svgz /usr/share/pixmap/

# create a directory for testing
mkdir /tmp/test

# copy some .desktop files to the testing directory. At least one should have the line "Icon=example"
cp -a example_working.desktop example_testing.desktop /tmp/test

# remove the users icon cache
rm -r ~/.kde4/cache-*/kpc/

# check if the icons gets displayed correctly
strace -e trace=access -o /tmp/test/konq_icon.strace  -f konqueror /tmp/test

# close konqueror

# in case of problems, analyse the strace log file
less /tmp/test/konq_icon.strace

/usr/share/mime/packages/
