Feature: Keyboard Support

[GoogleCodeExporter]

Feature Req: Keyboard support using HID-Support

Below is a patch that adds keyboard support using your HID-SUPPORT. The old 
mouse support was left in place since it displays the cursor and seemed to work 
better on my device (iPad 2 5.0.1)

Add libhidsupport.dylib to the project, and its header:

For the mouse cursor only using 2/3 of the iPad Air screen (Comment #40, #44, 
#45). Using Flex, you can correct the width/height parameters. It doesn't allow 
rotating the iPad but at least it works:

Class: SynergyClient
Method: -(void) setScreenWidth:(int) andHeight:(int)

Set width to 1024 and height to 768 for landscape. Switch the values if you're 
using portrait orientation. Tested on IOS 8.1.2 using the iSynergyClient from 
http://www.myrepospace.com/profile/thenorth

I'm working on a little project to make my iphone function as a laptop. I'm 
really close to getting it all to work.
Basically, I want to use a raspberrypi connected to a motorola lapdock as a 
terminal to connect remotely to my iphone 5.
I'm planning on using rplay and airplay mirroring for the video.
Before investigating synergy I tried out hidclient to connect the keyboard and 
mouse over bluetooth, but there wasn't enough documentation for me to get it 
working.
I also know that the Aten Tap Cs533 and the IOGear BLuetooth KVMs would work 
great to convert the usb mouse and keyboard over to bluetooth, but they are 
expensive and bulky.
I then found isynergyclient and deciced to give it a try. I too had the same 
issue with the mouse not covering the full screen.
I downloaded Full Force and had to set it to expand to iphone 6 screen size 
since I'm also using the Little Brother screen zoom hack.
Anyway, everything works great now except backspace and the arrow keys. I tried 
mapping the "\" key to backspace instead, but it's like the isynergyclient 
can't even pass the command to the phone.
Also, the on screen keyboard won't go away. Has anyone found a fix to these 
issues? It's just so anoying to be a backspace button and a couple of arrow 
keys away from finishing my project.
Anyway, I'm not much of a programmer so keep that in mind for your responses.

I tested thenorth iSynergyClient 0.9-2 and orientationnotify 0.1.0-2 on an iPad 
Air Retina (iOS 8.1.2). The synergy server is a Windows 8.1 with Synergy 
version 1.3.1.

The landscape mode / rotation doesn't work. The event is ignored, independant 
of the iSynergyClient being in foreground or background. The portrait mode 
works fine.

I installed the software via Cydia from thenorth.

Did somebody already patch it into portrait mode and has got a binary package?

AFAIK no one has patched rotation yet (iOS 8 changed a lot of things with 
rotation), though someone did fork the code on github 
https://github.com/supersaiyen/iSynergyClient

I've just followed the workaround in comment #51 but it's not working for me. 
I'm also using an iPad Air on iOS 8.1.2 and the cursor bumps up against that 
invisible wall. Does the version or variety of Synergy server have any effect 
on this issue? I'm using Synergy 1.5.0 in Win 7.
