Problem This is in response to NOT_Skeletor's Post titled "Alert the taskbar".
He would like to start or stop the blinking of the tray icon depending on the status of some external events.
In this example, you will see that the tray icon will blink once every 10 seconds. Each time the tray icon will blink for 3 seconds and stop by itself as shown below:
Solution
- To blink the tray icon, use the method GtkStatusIcon::set_blinking(true)
- To stop the blinking of the tray icon, use the method GtkStatusIcon::set_blinking(false)
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?
