Problem If you have run the example How to set up an application to run in the system tray using GtkStatusIcon - Part 4 - display popup menu on right click? or How to set up an application to run in the system tray using GtkStatusIcon - Part 5 - make the tray icon blink?, you will have noticed that if you keep pressing the right-mouse button on the system tray icon without selecting any of the menu item, you will end up having many popup windows surrounding the tray icon.
Let's fix this in this article as shown below:
Solution
- Use a variable as a flag to let us know if there's any active popup window.
- If there's already a previous popup window, pop it down using the method GtkMenu::popdown() before displaying the new popup window.
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?

If I right click to show the menu, how do you close the menu without actually choosing a selection? In other applications, such as winamp, if I right click for the menu and then click on the task bar or another application, the menu will just close. Thank you.

There doesn't seem to have any signal to notify us for the situation that you've described. Anybody has any clues?
December 27, 2007 9:36pm
maybe hiding the popup menu with a timerout event; but, in Linux(gnome-ubuntu 7.10) the popup menu dissapears when clicked in other places. I'm wrong?

Does anyone have anything new about the problem of closing the popup without selecting anything in it ? (By clicking somewhere else).
