Make KDE greeter

[Robert Ancell]

lightdm is desktop agnostic. A KDE/QT greeter would make it suitable for KDE.

[David Edmundson (david.edmundson)]

This is to be built as a Qt client library for lightdm and then a separate KDE greeter.

[Robert Ancell (robert-ancell)]

Thanks David!

A preview is available here:
http://gitweb.kde.org/scratch/davidedmundson/lightdm-qt.git/tree

Currently what will be the library, and a demo application are all in the same folder in an unorganised mess.

It will be merged into the main lightdm tree in the near future.

Hi David,

I've merged the greeter library changes into the lightdm branch. Question: did you add some annotations to the dbus .xml files to make them work with qdbusxml2cpp?

[David Edmundson (david.edmundson)]

Yes, I had to tell qdbusxml2cpp my internal names for any complex types (any structures/arrays, which aren't just simple ints, strings etc.

My display.xml looked like:

    <!-- Method for greeter to start authenticating a user -->
    <method name="StartAuthentication">
      <annotation name="org.freedesktop.DBus.GLib.Async" value="true"/>
      <arg name="username" direction="in" type="s"/>
      <arg name="result" direction="out" type="i"/>
      <arg name="requests" direction="out" type="a(is)"/>
     <annotation name="com.trolltech.QtDBus.QtTypeName.Out1" value="QList&lt;LdmAuthRequest&gt;"/>
  </method>

    <!-- Method for greeter to provide secrets for a user -->
    <method name="ContinueAuthentication">
      <annotation name="org.freedesktop.DBus.GLib.Async" value="true"/>
      <arg name="secrets" direction="in" type="as"/>
      <arg name="result" direction="out" type="i"/>
     <arg name="requests" direction="out" type="a(is)"/>
     <annotation name="com.trolltech.QtDBus.QtTypeName.Out1" value="QList&lt;LdmAuthRequest&gt;"/>
    </method>

I'm not sure it's worth editing the original .xml files to have these in.

Closing as we now have the example Qt greeter. Sure, it needs fixing up but it at least exists.
