Problem You would like to set up set up an application to run in the system tray.
Let's suppose we are setting an MP3 player. When the application is first started, an icon will appear in the system tray. Since no music is playing, the icon displayed is the standard Gtk::STOCK_MEDIA_STOP. When the user click on the icon, it will start playing, and we change the icon to the standard Gtk::STOCK_MEDIA_PLAY as shown below:
Solution
- Setting up the system tray icon is simple with the new widget GtkStatusIcon available in gtk+2.10 and above.
- In this example, we set the icon using standard stock images with
GtkStatusIcon::set_from_stock(). You can view the entire list of stock images here.
- You can also set tooltips on the icon using
GtkStatusIcon::set_tooltip()
- The signal 'activate' allow us to detect left mouse click.
- The signal 'popup-menu' allow us to detect right mouse click.
Important Note: This only works for PHP-GTK2 compliled with gtk+ v2.10 and above. If you are using an older version, for linux, you may follow the step-by-step instructions to recompile php-gtk2 with gtk+ v2.10. For windows, please refer to How to install php gtk2 on windows? You may also want to take a look here to see some of the new exciting PHP-GTK2 Functionalities.

This is part 1 of the series. I'm just trying to the show the fundamentals of setting up a GtkStatusIcon. As such, when you right click on the tray icon, you won't see any popup window in this example. You will only see the text "on_popup_menu" echoed in the command window.
The sample code in:
Sample Code 277: How to set up an application to run in the system tray using GtkStatusIcon - Part 4 - display popup menu on right click?
will show you the actual setup and display the popup window from the tray icon.
