on_show_option_menu

This signal is emitted when a select element in web_view needs to display a dropdown menu.

This signal can be used to show a custom menu, using menu to get the details of all items that should be displayed. The area of the element in the WebView is given as rectangle parameter, it can be used to position the menu. If this was triggered by a user interaction, like a mouse click, event parameter provides the Event. To handle this signal asynchronously you should keep a ref of the menu.

The event parameter is now deprecated. Use get_event to get the Event that triggered the dropdown menu.

The default signal handler will pop up a GtkMenu.

Parameters:

menu	the OptionMenu
rectangle	the option element area
event	the Event that triggered the menu, or null . Deprecated 2.40

Returns:

true to stop other handlers from being invoked for the event. false to propagate the event further.
