 Cross-platform, single header, super tiny C99 implementation of a system tray icon with a popup menu.

 The code is C++ friendly and will compile fine in C++98 and up.
 
-# Setup
+This fork is intended to bring together the [original work of Serge Zaitsev](https://github.com/zserge/tray) and the most interesting forks and PRs of respectable contributors:
 
-Before you can compile `tray`, you'll need to add an environment definition before the line where you include `tray.h`. 
+* [Only process messages coming from the tray window on Windows](https://github.com/zserge/tray/pull/18)
+* [Become C++-friendly](https://github.com/zserge/tray/pull/16)
+* [Fix all menu items have a check box](https://github.com/zserge/tray/pull/11)
+* [Add support for tooltip](https://github.com/zserge/tray/pull/11)
+* Darwin implementation translated from C to Objective C adapted from [@trevex fork](https://github.com/trevex/tray)
 
-**For Windows:**
+## Building
-```c
-#include <stdio.h>
-#include <string.h>
-
-#define TRAY_WINAPI
-
-#include "tray.h"
-...
-```
-
-**For Linux:**
-```c
-#include <stdio.h>
-#include <string.h>
-
-#define TRAY_APPINDICATOR
-
-#include "tray.h"
-...
-```
-
-**For Mac:**
-```c
-#include <stdio.h>
-#include <string.h>
-
-#define TRAY_APPKIT
-
-#include "tray.h"
-...
-```
-
-Failure to define one of the three above will result in a compile-time error.
-
-# Demo
-
-The included example `.c` files can be compiled based on your environment.
-
-For example, to compile and run the program on Windows: 
-
-```shell
-$> gcc example_windows.c [Enter]
-``` 
-
-This will compile and build `a.out`. To run it: 
 
 ```
-$> a [Enter]
+mkdir build
+cd build
+cmake ..
 ```
 
-# Example
+* On Linux/MacOS run the resulting Makefile with `make`
+* On Windows build the resulting Visual Studio solution
 
-```c

 Menu is a NULL-terminated array of items.

 array must have text field set to NULL.
 
-## Roadmap
-
-* [x] Cross-platform tray icon
-* [x] Cross-platform tray popup menu
-* [x] Separators in the menu
-* [x] Disabled/enabled menu items
-* [x] Checked/unchecked menu items
-* [x] Nested menus
-* [ ] Icons for menu items
-* [x] Rewrite ObjC code in C using ObjC Runtime (now ObjC code breaks many linters and static analyzers)
-* [ ] Call GTK code using dlopen/dlsym (to make binaries run safely if Gtk libraries are not available)
