== Installation ==
Unfortunately xstroke hasn't been actively maintained for a few years so there isn't a binary package you can directly install. However compiling the tool is straightforward and easy with the steps below. Credit for these installation steps goes to [http://ozzmaker.com/2014/06/17/raspberry-pi-with-stroke-and-gesture-recognition/ mwilliams03 at ozzmaker.com].
First install a few dependencies by opening a command window on the Pi and executing:
sudo apt-get -y install build-essential libxft-dev libxpm-dev libxtst-dev
Now download, compile, and install xstroke by executing:
<nowiki>cd ~
wget http://mirror.egtvedt.no/avr32linux.org/twiki/pub/Main/XStroke/xstroke-0.6.tar.gz
tar xfv xstroke-0.6.tar.gz
cd xstroke-0.6
./configure
make
sudo make install</nowiki>
If the commands above execute successfully xstroke should be installed. If you see an error message, carefully check the dependencies above were installed and try again.
Once xstroke is installed you will want to add a couple menu shortcuts to start and stop xstroke. Execute the following commands to install these shortcuts:
<nowiki>wget https://github.com/adafruit/PiTFT_Extras/raw/master/xstroke.desktop
wget https://github.com/adafruit/PiTFT_Extras/raw/master/xstrokekill.desktop
sudo cp xstroke*.desktop /usr/share/applications/</nowiki>
== Utiliser ==
To use xstroke I highly recommend using a plastic stylus instead of your finger. Also calibrate the touchscreen for X-Windows so you have the best control over the cursor possible.
