Fortunately, this FocusOut event indicates that the focus is going to move to a sub-window (identified by NotifyInferior) so it is allowed. Note that during the creation of the main window, another sub-window is created and a FocusOut event is sent to the active window.

The modified function opens /usr/lib/libX11.so.6 and invokes the real function.

Hijacking the events is done by over-riding XNextEvent.Ī shared library containing a modified implementation of XNextEvent is loaded using LD_PRELOAD.
FIREFOX FOCUS LINUX CODE
Implementation DetailsĪll of this describes the code in firefox/src/cpp/linux-specific/x_ignore_nofocus.c. Knowledge of the GDK event processing loop is also useful. To understand this solution, one should be familiar with X-Windows and its events. New window creation cannot be tracked - as it may happen as a side effect of many operations.
FIREFOX FOCUS LINUX WINDOWS
However, when multiple windows are involved - creating, switching or destroying, this component should be aware of it. The basic idea requires no interaction with other components of WebDriver. In this situation, special care must be taken. By design, WebDriver does not guarantee anything if the active window is closed - until a new window is being switched to.

The events that indicate loss of focus FocusOut are discarded. X-Windows notifies the application of events (user input, windows being destroyed, mouse movements) by asynchronous events. The basic idea is to get between the XLib (X-Windows client library) layer and the application. In case the user decides to switch to another window (a thing which could be understood),įirefox must not know it lost focus. In order for native events to be processed in Firefox, it must always retain focus. This page describes an essential component of the native events implementation on Linux - focus maintaining.
