Crosshair effect for KWin

Requirements

KWinCrosshair has been tested with Qt 4.8 and KWin 4.9, but it should work with Qt 4.6 and KWin 4.7 or newer.

Building and installing (the easy way)

In your terminal, go to the directory containing the project sources and run:

$ cmake -DCMAKE_INSTALL_PREFIX=~/.kde4
$ make
$ make install

This will install the effect for the current user only.

Proceed as described in "Enabling and configuring".

(alternative) Building and installing in /usr

In your terminal, go to the directory containing the project sources and run:

$ cmake -DCMAKE_INSTALL_PREFIX=/usr
$ make

Run make install as root, for example:

$ sudo make install

or:

$ su
# make install

This will install the effect into the /usr prefix, so it will be available for all users.

Enabling and configuring

First, to make sure that KWin detects the effect, log out and log in again to restart KDE, or restart KWin only by running:

$ nohup kwin --replace > /dev/null &

Then, go to "System Settings -> Desktop Effects -> All Effects" and select "Crosshair". Alternatively, you can run:

$ kcmshell4 kwincompositing
