樹莓派使用虛擬鍵盤

1、安裝必需文件

sudo apt-get install libfakekey-dev libpng-dev -y

2、安裝編譯虛擬鍵盤ato, sans-serif;font-size:16px;font-weight:700;vertical-align:baseline;color:#2B2B2B;background-color:#FFFFFF;">matchbox-keyboard
ato, sans-serif;font-size:16px;font-weight:700;vertical-align:baseline;color:#2B2B2B;background-color:#FFFFFF;">
git clone https://github.com/mwilliams03/matchbox-keyboard.git
cd matchbox-keyboard
./autogen.sh
make
sudo make install
3、安裝虛擬鍵盤所用的共享庫

ato, sans-serif;font-size:16px;font-weight:700;vertical-align:baseline;color:#2B2B2B;background-color:#FFFFFF;">
sudo apt-get install libmatchbox1 -y
4、創建虛擬鍵盤啟動腳本

sudo nano /usr/bin/toggle-matchbox-keyboard.sh

粘貼以下內容並按ctrl+x和y保存退出

#!/bin/bash
#This script toggle the virtual keyboard

PID=`pidof matchbox-keyboard`
if [ ! -e $PID ]; then
  killall matchbox-keyboard
else
 matchbox-keyboard&
fi
給以上腳本增加可執行權限
sudo chmod +x /usr/bin/toggle-matchbox-keyboard.sh

   5、把以上腳本增加到開始菜單

sudo nano /usr/share/applications/toggle-matchbox-keyboard.desktop

[Desktop Entry]
Name=Toggle Matchbox Keyboard
Comment=Toggle Matchbox Keyboard
Exec=toggle-matchbox-keyboard.sh
Type=Application
Icon=matchbox-keyboard.png
Categorices=Panel;Utility;MB
X-MB-INPUT-MECHANSIM=Ture

go on…\

nano ~/.config/lxpanel/LXDE-pi/panels/panel

找到以下內容

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

改為以下內容

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


可以用加參數在啟動時改變虛擬鍵盤大小

matchbox-keyboard -s 50

通過SSH在桌面上顯示可以用這個命令：

DISPLAY=:0.0 matchbox-keyboard

顯示小鍵盤用以下命令參數

matchbox-keyboard -s 50 extended
