Hardcoded icon path in launcher for GNU/Linux systems

[palob]

Hi,

currently the icon path specified in the created .desktop launcher file is set to:
Icon=@pixmapsdir@/wxmedit.png.

This prevents icon theming without editing the launcher file.

The icon is installed to pixmapsdir = $(datadir)/pixmaps cf. here, i.e. /usr/share/pixmaps or ~/.local/share/pixmaps effectively.

According to the resources linked below freedesktop.org standard icon locations are:
/usr/share/icons/hicolor/[size]/apps/[icon name]
~/.local/share/icons/hicolor/[size]/apps/[icon name]
/usr/share/pixmaps/[icon name]

http://standards.freedesktop.org/icon-theme-spec/icon-theme-spec-latest.html

So you install the icon to a standard location already. According to the freedesktop.org standard and w.r.t. the icon lookup mechanism of all desktop environment the simple Icon line

Icon=wxmedit

without the full path and without file extension should suffice.

Well, I will confirm whether it works under different distributions and non-linux system such as BSD, OpenIndiana etc.

Unfortunately, There is no environment variable $XDG_DATA_DIRS set under OpenIndiana.
Thus, if wxmedit installed with prefix=/usr/local, the desktop can not find the icon if not using absolute path.

IMHO this is a bug in OpenIndiana. They should set $XDG_DATA_DIRS.
