Home found the keyboard some keys have failed, no way, and windows, directly install a virtual key, is also flattered!

Matchbox-keyboard is a "virtual" or "software" keyboard on the screen for small touchscreen TFT connected to the Raspberry Pi.

The Matchbox-keyboard keyboard also uses an XML file to specify the layout of the key, which makes it highly customizable.

1. Install the prerequisite development package

[Email protected] ~ $ sudo apt-get install Libfakekey-dev libpng-dev libxft-dev autoconf libtool-y

2. Install and compile Matchbox-keyboard

[Email protected] ~ $ git clone https://github.com/mwilliams03/matchbox-keyboard.git[email Protected] ~ $ cd matchbox-~/matchbox-keyboard $./~/matchbox-keyboard  ~/ Matchbox-keyboard  $ sudo make install

After installing Matchbox-keyboard, you need to install the shared Matchbox Library.

[Email protected] ~ $ sudo apt-get Install Libmatchbox1-y

3. Create a toggle script to start or stop Matchbox-keyboard
We will now create a script to turn the keyboard on and off. Then add a menu item to access the script and add an icon to the taskbar for easy access.

Create a new file;

[Email protected] ~ $ sudo nano/usr/bin/toggle-matchbox-keyboard.sh

and copy the following text in;

#!/bin/virtual  keyboardpid= ' pidof matchbox-keyboard 'if [!-e $PID] ; Then  killall Matchbox-keyboardelse  matchbox-keyboard&fi

Now let it be executable;

[Email protected] ~ $ sudo chmod +x/usr/bin/toggle-matchbox-keyboard.sh

We will now add an item to the Start menu;

for older mirrors;

[Email protected] ~ $ sudo nano/usr/local/share/applications/toggle-matchbox-keyboard.desktop

For newer mirrors, including Jessie; (I'm a new image here, so use this command)

[Email protected] ~ $ sudo nano/usr/share/applications/toggle-matchbox-keyboard.desktop

Copy the following contents;

[Desktop entry]name=Toggle matchbox keyboardcomment=Toggle matchbox keyboardexec= toggle-matchbox-Keyboard.shtype=applicationicon=matchbox-keyboard.pngcategories= Panel; Utility; MBX-mb-input-mechansim=true

To create an icon on the taskbar, open the LXDE panel configuration;

[Email protected] ~ $ nano ~/.config/lxpanel/lxde/panels/panel

If the file above is empty, then it is likely that you are using a newer version of Raspbian, especially if you are using Pi 2.

You need to edit the panel configuration in this position;

If using Raspbian WHEEZY;

[Email protected] ~ $ nano ~/.config/lxpanel-pi/lxde/panels/panel

If you use Raspbian JESSIE; (I use this command here)

[Email protected] ~ $ nano ~/.config/lxpanel/lxde-pi/panels/panel

Find this part of the configuration;

Plugin {    = Launchbar    Config {        Button {            id=lxde-screenlock.desktop        }        Button {            id=lxde-logout.desktop        }    }

Add id=toggle-matchbox-keyboard.desktop code to go in;

Plugin {    = Launchbar    Config {        Button {            id=toggle-matchbox-keyboard.desktop        }        button {            id=lxde-screenlock.desktop        }        button {            id=lxde-logout.desktop        }    }

4. More information

You can use the following statement to start Matchbox-keyboard from the command linekeyboard.

[Email protected] ~ $ matchbox-keyboard

This will load the default keyboard layout;

Matchbox-keyboard can also resize the window using the-s integer parameter. An integer is a value between 30%-100% of the screen width.
This is the Defualt keyboard layout loaded at 50% of the screen width;

Matchbox-keyboard also supports custom keyboards, and some have been loaded into/usr/local/share/matchbox-keyboard/in. It's easy to use your own.
