Is it possible to change the look and feel of remote X applications running under Xming?

I am running Eclipse remotely right now, in Xming on my Windows pc, through an ssh tunnel from my laptop running Ubuntu 11.10.

As seen below, it doesn't look that bad, but it seems that my applications defaults to the standard theme when it cannot find any others for GTK+ applications.

Is there anything I can do about this? Also it would be nice if I could do something about the font settings to make it more easily readable.

Just install gtk-chtheme

$ sudo apt-get install gtk-chtheme

and call it in a terminal opened in Xming

$ gtk-chtheme

Also, you can use LXAppearance:

$ sudo apt-get install lxappearance

and call it as

$ lxappearance

(LXAppearance is, technically, part of LXDE, but the configuration file it creates is generic for GTK 2.0)
