Tray
|
||||
----
|
||||
|
||||
Cross-platform, single header, super tiny C99 implementation of a system tray icon with a popup menu.
|
||||
|
||||
Works well on:
|
||||
|
||||
* Linux/Gtk (libappindicator)
|
||||
* Windows XP or newer (shellapi.h)
|
||||
* MacOS (Cocoa/AppKit)
|
||||
|
||||
There is also a stub implementation that returns errors on attempt to create a tray menu.
|
||||
|
||||
# Setup
|
||||
|
||||
Before you can compile `tray`, you'll need to add an environment definition before the line where you include `tray.h`.
|
||||
|
||||
**For Windows:**
|
||||
```c
|
||||
#include <stdio.h>
|
||||
#include <string.h>
|
||||
|
||||
#define TRAY_WINAPI 1
|
||||
|
||||
#include "tray.h"
|
||||
...
|
||||
```
|
||||
|
||||
**For Linux:**
|
||||
```c
|
||||
#include <stdio.h>
|
||||
#include <string.h>
|
||||
|
||||
#define TRAY_APPINDICATOR 1
|
||||
|
||||
#include "tray.h"
|
||||
...
|
||||
```
|
||||
|
||||
**For Mac:**
|
||||
```c
|
||||
#include <stdio.h>
|
||||
#include <string.h>
|
||||
|
||||
#define TRAY_APPKIT 1
|
||||
|
||||
#include "tray.h"
|
||||
...
|
||||
```
|
||||
|
||||
# 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]
|
||||
```
|
||||
|
||||
# Example
|
||||
|
||||
```c
|
||||
struct tray tray = {
|
||||
.icon = "icon.png",
|
||||
.menu = (struct tray_menu[]){{"Toggle me", 0, 0, toggle_cb, NULL},
|
||||
{"-", 0, 0, NULL, NULL},
|
||||
{"Quit", 0, 0, quit_cb, NULL},
|
||||
{NULL, 0, 0, NULL, NULL}},
|
||||
};
|
||||
|
||||
void toggle_cb(struct tray_menu *item) {
|
||||
item->checked = !item->checked;
|
||||
tray_update(&tray);
|
||||
}
|
||||
|
||||
void quit_cb(struct tray_menu *item) {
|
||||
tray_exit();
|
||||
}
|
||||
|
||||
...
|
||||
|
||||
tray_init(&tray);
|
||||
while (tray_loop(1) == 0);
|
||||
tray_exit();
|
||||
|
||||
```
|
||||
|
||||
# API
|
||||
|
||||
Tray structure defines an icon and a menu.
|
||||
Menu is a NULL-terminated array of items.
|
||||
Menu item defines menu text, menu checked and disabled (grayed) flags and a
|
||||
callback with some optional context pointer.
|
||||
|
||||
```c
|
||||
struct tray {
|
||||
char *icon;
|
||||
struct tray_menu *menu;
|
||||
};
|
||||
|
||||
struct tray_menu {
|
||||
char *text;
|
||||
int disabled;
|
||||
int checked;
|
||||
|
||||
void (*cb)(struct tray_menu *);
|
||||
void *context;
|
||||
|
||||
struct tray_menu *submenu;
|
||||
};
|
||||
```
|
||||
|
||||
* `int tray_init(struct tray *)` - creates tray icon. Returns -1 if tray icon/menu can't be created.
|
||||
* `void tray_update(struct tray *)` - updates tray icon and menu.
|
||||
* `int tray_loop(int blocking)` - runs one iteration of the UI loop. Returns -1 if `tray_exit()` has been called.
|
||||
* `void tray_exit()` - terminates UI loop.
|
||||
|
||||
All functions are meant to be called from the UI thread only.
|
||||
|
||||
Menu arrays must be terminated with a NULL item, e.g. the last item in the
|
||||
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)
