iOS example

Introduction

This example is the default XCode "OpenGL" example code, modified to support ImGui and Synergy.

Synergy (remote keyboard/mouse) is not required, but it's pretty hard to use ImGui without it. Synergy includes a "uSynergy" library that allows embedding a synergy client, this is what is used here. ImGui supports "TouchPadding", and this is enabled when Synergy is not active.

How to Use

In Synergy, go to Preferences, and uncheck "Use SSL encryption"
Run the example app.
Tap the "servername" button in the corner
Enter the name or the IP of your synergy host
If you had previously connected to a server, you may need to kill and re-start the app.

Notes and TODOs

Things that would be nice but I didn't get around to doing:

iOS software keyboard not supported for text inputs
iOS hardware (bluetooth) keyboards not supported
Graceful disconnect/reconnect from uSynergy.
Copy/Paste not well-supported

C++ on iOS

ImGui is a c++ library. If you want to include it directly, rename your Obj-C file to have the ".mm" extension.

Alternatively, you can wrap your debug code in a C interface, this is what I am demonstrating here with the "debug_hud.h" interface. Either approach works, use whatever you prefer.

In my case, most of my game code is already in C++ so it's not really an issue and I can use ImGui directly.
