Unfortunately xstroke hasn't been actively maintained for a few years so there isn't a binary package you can directly install.

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>

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.

Introduction

With the PiTFT touchscreen and xstroke you can enter text in applications by drawing simple character gestures on the screen!

Cette technique d'entrée par geste est appelée "Gesture Input" en Français.

Check out the video below for a short demonstration and overview of gesture input with xstroke (Vidéo par Tony DiCola, anglais):
