What are the 'correct' desktop icon sizes for KDE applications?

The correct icon sizes are
16x16
22x22
32x32
48x48
64x64
128x128

Regarding desktop icon sizes, that is up to the user. This can be set in
kcontrol > Appearances > Icons > Advanced

How do you configure them when your app is installed, so that one appears on the desktop and launches your application?

You have to create a .desktop file. Just take a look at another one, or look here
http://freedesktop.org/Standards/desktop…spec-0.9.4.html

That's great thanks!

Unfortunately, it doesn't say where this .desktop file should be created. Is it the users home directory, the application installation directory or somewhere else? How will the DE know where to find it?

Thanks.

Here are two other specs that may be of interest to you:
http://freedesktop.org/Standards/basedir-spec
http://freedesktop.org/Standards/menu-spec

I found them on the page http://freedesktop.org/Standards/ under the headline: "Here are draft specifications that are new and not yet widely used, though they may be used by one or more desktops or desktop applications"

IIRC they are supported by KDE but I don't know first-hand.

They are since KDE 3.2

As for the icon on the desktop: I wouldn't install an icon there at application install time, but you could offer an option in your program or at first startup to create such an icon.
If the users likes this, create a similar desktop file (copy the file) to the user's desktop path.
See http://api.kde.org/3.3-api/kdecore/html/classKGlobalSettings.html#e11

But usually programs don't do that, a user can always drag&drop the "link" from the menu to his/her desktop if needed.

Cheers,
