Holger Kaelberer 040ad7357b kdeconnect-kde: Add remotekeyboard plugin
Allow to inject keypress events to remote peers (most notably Android devices)

Notes / open issues / possible improvements:

- For the json-payload I used the syntax of the key-events as sent by mousepad-plugin with the addition of a "sendAck"-flag. If "sendAck" is set to true the remote peer should echo a key-event if it could be handled, thus allowing the local client to find out whether the key was accepted. For performance reasons, it's allowed to send multi-char strings in the "key" property (performs much better if you send a whole string via "echo '...' |  kdeconnect-cli ..." e.g.)

- kdeconnect-cli: For now takes a string and transforms it into single key-events for visible characters only. In a first implementation I used a kbhit() helper that used termios.h to catch and relay keypresses interactively (including some special-events), which was not optimal. A better approch might be to use linux input-api directly. Would this be an option regarding cross-platform compatibility or can I assume to develop for Linux only? Being a command-line guy, I'd really like to have a fully featured kdeconnect-cli interface ;-)

- Factor out the Qt::Key-to-internal keymap to some core-helper because it corresponds to the mapping in the mousepad-plugin?

- The plasmoid is not perfect as it is: A single line containing a non-echoing TextField (i.e. it eats all the KeyPress events), and only ack-ed keypress-packets from the peer device are injected if they contain visible keys. Advantage: the user sees whether his key-presses are accepted by the peer device. Disadvantage: The echoed text does not correspond 1:1 to what is shown on the peer's display, user might be confused when typing without success. I played around with different variations each of which with its proper shortcomings:
1. An echoing Textfield for typing: Has the advantage that the user can directly see what he is typing, which makes interaction in the typing field easier, BUT messes up interaction if the Editor on the peer is changed silently and does not notify the user if his keypresses are not handled by the peer.
2. A non-echoing TextField for typing PLUS a readonly one for printing visible echoed keys. Disadvantage: same as for the previous one and uses more space on the plasmoid.
Comments? Ideas?

README.txt Added a README about how to create a plugin. 2014-12-21 19:37:41 -08:00

Writting a plugin for KDE Connect
=================================

For the desktop client (this project):
--------------------------------------

1. Enter the "plugins" directory.
2. Copy the "ping" under a different name ("findmyphone" in this example).
3. Add "add_subdirectory(findmyphone)" to CMakeLists.txt after the others "add_subdirectory".
1. Enter the new "findmyphone" directory.
5. Edit CMakeLists.txt by replacing "ping" with "findmyphone".
6. Rename other files in this directory by replacing "ping" with "findmyphone"
7. Write a description of your plugin into "README"
8. Edit findmyphoneplugin.cpp and findmyphoneplugin.h.
  A. Change license header.
  B. Replace (case sensitive) "ping" with "findmyphone", "PingPlugin" with "FindMyPhonePlugin" and "PING" with "FINDMYPHONE".
9. Edit kdeconnect_findmyphone.desktop file:
  A. Replace "ping" with "findmyphone".
  B. Change name, description, icon, author, email, version, website, license info.
  C. Remove all the translations
  D. Set X-KDEConnect-SupportedPackageType and X-KDEConnect-OutgoingPackageType to the package type your plugin will receive
     and send, respectively. In this example this is "kdeconnect.findmyphone". Make sure that this matches what is defined in
     the findmyplugin.h file (in the line "#define PACKAGE_TYPE_..."), and also in Android.
10. Now you have an empty skeleton to implement your new plugin logic.

For Android (project kdeconnect-android):
-----------------------------------------

1. Change directory to src/org/kde/kdeconnect/Plugins.
2. Copy "PingPlugin" under a different name ("FindMyPhonePlugin" in this example).
1. Enter the new "FindMyPhonePlugin" directory.
4. Rename "PingPlugin.java" to "FindMyPhonePlugin.java"
5. Edit it. Replace (case sensitive) "Ping" with "FindMyPhone", "ping" with "findmyphone", "PING" with "FINDMYPHONE"
   and "plugin_ping" with "plugin_findmyphone".
6. Open res/values/strings.xml. Find and copy the lines "pref_plugin_ping_desc" and "pref_plugin_ping" replacing "ping"
   with "findmyphone" and edit the plugin name and description between <string> </string>).
7. Open src/org/kde/kdeconnect/Plugins/PluginFactory.java.
  A. Copy "import … PingPlugin" line with replacing "PingPlugin" with "FindMyPhonePlugin".
  B. Copy "PluginFactory.registerPlugin(PingPlugin.class);" line with replacing "PingPlugin" with "FindMyPhonePlugin".
8. Open src/org/kde/kdeconnect/NetworkPackage.java. Copy a "public final static String PACKAGE_TYPE_PING = …" line
   replacing "PING" with the package type you will be using (should match the desktop client).
9. Now you have an empty skeleton to implement your new plugin logic.
