Navboard is a general purpose application designed to translate touch/mouse events into arbitrary actions. This makes it ideal as a on-screen reader (OSK) but it can also server as a general application launcher.
make;
make install
Note that default settings can be customized by modifying config.h/config.c
The following libraries are needed to build
- Standard X libs: -lX11 -lxcb
- X WM helper libs: -lxcb-ewmh -lxcb-icccm
- Lib to send fake key/button events: Library-lxcb-xtest
- Font related libs: -lxcb-render -lxcb-render-util -lfreetype
For tests, scunittest is also needed.
navboard opens up a launcher to select the board to use. The default action can be changed by setting NAVBOARD_DEFAULT env variable
navboard board_of_boards same as the above
navboard qwerty opens up the default OSK (standard qwerty layout)
navboard mobile opens up the default mobile OSK
navboard is installed system wide but users can each have their own boards.
To add your own board add the c source file to ${XDG_CONFIG_DIR:-$HOME/.config}/navboard/
and then run navboard -r to recompile a local copy for the given user. Future
runs of navboard will show all custom boards defined for the user.
Any excutable file ending in *.sh that is in ${XDG_CONFIG_DIR:-$HOME/.config}/navboard/ will be run before recompliatoin. This can be used to create boards based on the layout of the running system.
For a real example see volume.h and volume_board_gen.sh. These scripts work to getter to create a board based on the existing alsa devices and server to provide graphical volume controller. The neat part is I can use the same script on all my devices.
In samples/, there are some toy boards to demenstrate some functionality that is beyond a typical OSK. However to avoid overcomplicating them, they don't actually do anything.
build with SAMPLES=1 to include these dummy examples
