Problem This is in response to NOT_Skeletor's Post titled "Alert the taskbar".
In the the previous article, I've showed you how to blink the tray icon.
In the post by Bob Majdak Jr, he shared with us the way to blink an application.
The following example shows both the blinking of tray icon and blinking of the application - to show you how you can mix the two, and also the key differences between the two as shown below:
Solution
- To blink the application, use the method GtkWindow::set_urgency_hint(true)
- To stop the blinking of the application, use the method GtkWindow::set_urgency_hint(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? You may also want to take a look here to see some of the new exciting PHP-GTK2 Functionalities.

Explanation The sample code above is an extension of How to set up an application to run in the system tray using GtkStatusIcon - Part 5 - make the tray icon blink?
What's new here:
- Blink the tray icon every 10 seconds.
- Blink the icon.
- Blink the application.
- Stop the blinking after 3 seconds.
- Stop the blinking of the tray icon.
- Stop the blinking of the application.
Note
- If the application is hidden, you will not see any blinking of the applicatioin. In this case, you will only see the tray icon blinking.
- If the application is not hidden, but is hidden by other windows, you will see both the tray icon, and the application in the taskbar, blinking.
- If the application is in view, you will see all three blinking - the application, the icon in the task bar, and the system tray icon.
