In the Carbon event model, my NPP_HandleEvent function receives "get focus" events, but never receives any "lose focus" events. 

These events correspond to NPEventType_GetFocusEvent and NPEventType_LoseFocusEvent in npapi.h.

In PluginViewMac.cpp, there is a setFocus() function that sends a "getFocusEvent" type of event, but there's no corresponding "loseFocusEvent" event sent anywhere in the file (or in any other file for that matter). 

To reproduce the problem, your plugin's NPP_HandleEvent function should listen for getFocusEvent and loseFocusEvent types of events. When you click in the plugin's region, your plugin will receive a getFocusEvent event. Clicking outside the plugin's region should send a loseFocusEvent type of event, but none is received by the plugin. 

Apparently Chrome has (or had) a similar bug:

(Bug reported against Qt version 4.6.2)
