Set Qt mouse pointer inside GNOME

You don’t have to install theme packages, engines or extra apps. All you need is already on your Debian system:

# update-alternatives --config x-cursor-theme There are 2 choices for the alternative x-cursor-theme (providing /usr/share/icons/default/index.theme).

Selection    Path                             Priority  Status
------------------------------------------------------------
* 0     /usr/share/icons/DMZ-White/cursor.theme   90    auto mode
  1     /usr/share/icons/DMZ-Black/cursor.theme   30    manual mode
  2     /usr/share/icons/DMZ-White/cursor.theme   90    manual mode

Press enter to keep the current choice[*], or type selection number: 1 update-alternatives: using /usr/share/icons/DMZ-Black/cursor.theme to provide /usr/share/icons/default/index.theme (x-cursor-theme) in manual mode.

If you’re not using Debian, it seems the way to go is to follow /usr/share/icons/default/index.theme with the following:

[Icon Theme]
Inherits=DMZ-Black

Either method sets the cursor theme systemwide through Xorg itself. To set it for a single user, add the following to ~/.Xdefaults:

Xcursor.theme: DMZ-Black
Xcursor.size: SIZE #optional

In my own case, I was using the the DMZ-Black theme on GTK applications, but Qt3/Qt4 applications (Amarok 1.4, Clementine, Skype, KeepassX) had the mouse pointer switch to DMZ-White when it entered their windows. Nothing that would cause trouble, but annoying if you want a consistent look across your environment.

As said before, this avoids unnecesary cruft on your system and works for all desktop environments you might have on your system.
