## **Description**
`gxkb` is a tiny indicator applet which allows to quickly switch between different keyboard layouts in `X`.
A flag corresponding to the country of the active layout is shown in the indicator area.
The applet is written in `C` and uses `GTK+` library and therefore does not depend on any `GNOME` components.

## **Dependencies**

* `GTK3`
* `libwnck-3`
* `libxklavier16`
* `libayatana-appindicator3`

## **Installing**

### Debian and Ubuntu

```bash
sudo apt-get install gxkb
```

### Fedora

```bash
sudo dnf install gxkb
```

## **Building from source**

* Install dependencies

    + Debian

        ```bash
        sudo apt-get install libwnck-3-dev libxklavier-dev libgtk-3-dev dh-autoreconf dh-make devscripts fakeroot
        ```
        For AppIndicator support:
        ```bash
        sudo apt-get install libayatana-appindicator3-dev
        ```

* Build

    ```bash
    wget https://github.com/zen-tools/gxkb/archive/master.tar.gz -O gxkb.tar.gz
    tar xzf gxkb.tar.gz
    cd gxkb-master
    ./autogen.sh
    ./configure
    ```
    For AppIndicator support:
    ```bash
    ./configure --enable-appindicator=yes
    ```
    Then:
    ```bash
    make && sudo make install
    ```

## **Usage**

* Show version and features

    ```bash
    gxkb -v
    ```

* Run from a terminal

    ```bash
    gxkb &
    ```

## **Features**

* [AppIndicator](https://wiki.ubuntu.com/DesktopExperienceTeam/ApplicationIndicators) support

    To switch that off use the following command during building phase:

    ```bash
    ./configure --enable-appindicator=no
    ```

* Custom flags support

    Put your flag images in `.local/share/gxkb/flags` in PNG format
    with the names like `<country code>.png`,
    e.g. `us.png`, `ru.png`, `ua.png`
    and the sizes of 24x24 pixels each

* Scrolling support

    Switch layouts by scrolling while hovering over the flag

* Using Scroll Lock led to indicate alternate layouts

    Can be changed in `.config/gxkb/gxkb.cfg`

## **Configuration**

Configuration is done via config file: `.config/gxkb/gxkb.cfg`

The most interesting options are:
`layouts=us,ru,ua`
`toggle_option=grp:alt_shift_toggle,grp_led:scroll,terminate:ctrl_alt_bksp`

Instead of `grp:alt_shift_toggle` you can use whatever the following command gives you:
`grep grp:.*toggle /usr/share/X11/xkb/rules/base.lst`

## **Known issues**

* In Elementary OS Freya `gxkb` does not work. Trying to figure out why.

* In Gnome2/Gnome3, Unity, E17, possibly in KDE3/KDE4:
  **Q**: _The layout does not get changed properly while switching between
  windows._
  **A**: In your DE settings find keyboard layout control settings, disable
  the inheriting of the layouts from parent window and disable splitting
  layouts between windows.

* In Gnome3/Unity:
  **Q**: _The layout icon is not displayed in system tray area._
  **A**: Due to different versions of Gnome3 there is no easy answer, Google
  might help to find the right one.
  But in fact `gxkb` works under the hood, so you can use the Gnome3/Unity
  system indicators for icon displaying, just don't forget to disable the
  splitting layouts between different windows.

* In XFCE 4.12:
  **Q**: _The layout icon is not displayed in system tray area._
  **A**: In "sessions and startup" settings try to find and disable
  <code>indicator&#8209;application&#8209;service</code>.
  More details [here](https://forum.xfce.org/viewtopic.php?pid=32908#p32908).

* In Unity + AppIndicator:
  **Q**: _The layout switching does not work._
  **A**: It can happen when the system layout switcher
  <code>indicator&#8209;keyboard</code> uses the same key combination.
  One possible solution to this may be to assign an unused key combination
  for <code>indicator&#8209;keyboard</code>.
  Another solution may be to remove the package
  <code>indicator&#8209;keyboard</code>, but that will also remove the Unity
  control center, which will be replaced by a Gnome control center.
