-This file is what every viewer plugin writer should refer to.
-
-
-Module Related API
-
-A viewer plugin is, before anything, a plugin. As a dynamically loadable
-module, it thus has an init and a destroy function called whenever it is
-loaded/initialized and unloaded/destroyed. A graphical module depends on
-lttvwindow for construction of its viewer instances. In order to achieve
-this, it must register its constructor function to the main window along
-with button description or text menu entry description. A module keeps
-a list of every viewer that currently sits in memory so it can destroy
-them before the module gets unloaded/destroyed.
-
-The contructor registration to the main windows adds button and menu
-entry to each main window, thus allowing instanciation of viewers.
-
-
-Main Window
-
-The main window is a container that offers menus, buttons and a
-notebook. Some of those menus and buttons are part of the core of the
-main window, others are dynamically added and removed when modules are
-loaded/unloaded.
-
-The notebook contains as much tabs as wanted. Each tab is linked with
-a set of traces (traceset). Each trace contains many tracefiles (one
-per cpu). A trace corresponds to a kernel being traced. A traceset
-corresponds to many traces read together. The time span of a traceset
-goes from the earliest start of all the traces to the latest end of all
-the traces.
-
-Inside each tab are added the viewers. When they interact with the main
-window through the lttvwindow API, they affect the other viewers located
-in the same tab as they are.
-
-The insertion of many viewers in a tab permits a quick look at all the
-information wanted in a glance. The main window does merge the read
-requests from all the viewers in the same tab in a way that every viewer
-will get exactly the events it asked for, while the event reading loop
-and state update are shared. It improves performance of events delivery
-to the viewers.
-
-
-
-Viewer Instance Related API
-
-The lifetime of a viewer is as follows. The viewer constructor function
-is called each time an instance view is created (one subwindow of this
-viewer type is created by the user either by clicking on the menu item
-or the button corresponding to the viewer). Thereafter, the viewer gets
-hooks called for different purposes by the window containing it. These
-hooks are detailed below. It also has to deal with GTK Events. Finally,
-it can be destructed by having its top level widget unreferenced by the
-main window or by any GTK Event causing a "destroy-event" signal on the
-its top widget. Another possible way for it do be destroyed is if the
-module gets unloaded. The module unload function will have to emit a
-"destroy" signal on each top level widget of all instances of its viewers.
-
-
-Notices from Main Window
-
-time_window : This is the time interval visible on the viewer's tab. Every
- viewer that cares about being synchronised by respect to the
- time with other viewers should register to this notification.
- They should redraw all or part of their display when this occurs.
-
-traceset : This notification is called whenever a trace is added/removed
- from the traceset. As it affects all the data displayed by the
- viewer, it sould redraw itself totally.
-
-filter : FIXME : describe..
-
-current_time: Being able to zoom nearer a specific time or highlight a specific
- time on every viewer in synchronicity implies that the viewer
- has to shown a visual sign over the drawing or select an event
- when it receives this notice. It should also inform the main
- window with the appropriate report API function when a user
- selects a specific time as being the current time.
-
-dividor : This notice links the positions of the horizontal dividors
- between the graphic display zone of every viewer and their Y axis,
- typically showing processes, cpus, ...
-
-
-Reporting Changes to the Main Window
-
-In most cases, the enclosing window knows about updates such as described
-in the Notification section higher. There are a few cases, however, where
-updates are caused by actions known by a view instance. For example,
-clicking in a view may update the current time; all viewers within
-the same window must be told about the new current time to change the
-currently highlighted time point. A viewer reports such events by calling
-lttvwindow_report_current_time on its lttvwindow. The lttvwindow will
-consequently call current_time_notify for each of its contained viewers.
-
-
-Available report methods are :
-
-lttvwindow_report_time_window : reports the new time window.
-lttvwindow_report_current_time : reports the new current time.
-lttvwindow_report_dividor : reports the new horizontal dividor's position.
-lttvwindow_report_filter : reports the new filter object
-
-
-
-Requesting Events to Main Window
-
-Events can be requested by passing a EventsRequest structure to the main
-window. They will be delivered later when the next g_idle functions
-will be called. Event delivery is done by calling the event hook for
-this event ID, or the main event hooks. A pointer to the EventsRequest
-structure is passed as hook_data to the event hooks of the viewers.
-
-EventsRequest consists in
-- a pointer to the viewer specific data structure
-- a start timestamp or position
-- a stop_flag, ending the read process when set to TRUE
-- a end timestamp and/or position and/or number of events to read
-- hook lists to call for traceset/trace/tracefile begin and end, and for each
- event (event hooks and event_by_id hooks).
-
-The main window will deliver events for every EventRequests it has
-pending through an algorithm that guarantee that all events requested,
-and only them, will be delivered to the viewer between the call of the
-tracefile_begin hooks and the call of the tracefile_end hooks.
-
-If a viewer wants to stop the event request at a certain point inside the
-event hooks, it has to set the stop_flag to TRUE and return TRUE from the
-hook function. Then return value will stop the process traceset. Then,
-the main window will look for the stop_flag and remove the EventRequests
-from its lists, calling the process_traceset_end for this request (it
-removes hooks from the context and calls the after hooks).
-
-It no stop_flag is risen, the end timestamp, end position or number
-of events to read has to be reached to determine the end of the
-request. Otherwise, the end of traceset does determine it.
-
-
-GTK Events
-
-Events and Signals
-
-GTK is quite different from the other graphical toolkits around
-there. The main difference resides in that there are many X Windows
-inside one GtkWindow, instead of just one. That means that X events are
-delivered by the glib main loop directly to the widget corresponding to
-the GdkWindow affected by the X event.
-
-Event delivery to a widget emits a signal on that widget. Then, if a
-handler is connected to this widget's signal, it will be executed. There
-are default handlers for signals, connected at class instantiation
-time. There is also the possibility to connect other handlers to these
-signals, which is what should be done in most cases when a viewer needs
-to interact with X in any way.
-
-
-
-Signal emission and propagation is described there :
-
-http://www.gtk.org/tutorial/sec-signalemissionandpropagation.html
-
-For further information on the GTK main loop (now a wrapper over glib main loop)
-see :
-
-http://developer.gnome.org/doc/API/2.0/gtk/gtk-General.html
-http://developer.gnome.org/doc/API/2.0/glib/glib-The-Main-Event-Loop.html
-
-
-For documentation on event handling in GTK/GDK, see :
-
-http://developer.gnome.org/doc/API/2.0/gdk/gdk-Events.html
-http://developer.gnome.org/doc/API/2.0/gdk/gdk-Event-Structures.html
-
-
-Signals can be connected to handlers, emitted, propagated, blocked,
-stopped. See :
-
-http://developer.gnome.org/doc/API/2.0/gobject/gobject-Signals.html
-
-
-
-
-The "expose_event"
-
-Provides the exposed region in the GdkEventExpose structure.
-
-There are two ways of dealing with exposures. The first one is to directly
-draw on the screen and the second one is to draw in a pixmap buffer,
-and then to update the screen when necessary.
-
-In the first case, the expose event will be responsible for registering
-hooks to process_traceset and require time intervals to the main
-window. So, in this scenario, if a part of the screen is damaged, the
-trace has to be read to redraw the screen.
-
-In the second case, with a pixmap buffer, the expose handler is only
-responsible of showing the pixmap buffer on the screen. If the pixmap
-buffer has never been filled with a drawing, the expose handler may ask
-for it to be filled.
-
-The interest of using events request to the main window instead of reading
-the events directly from the trace comes from the fact that the main
-window does merge requests from the different viewers in the same tab so
-that the read loop and the state update is shared. As viewers will, in
-the common scenario, request the same events, only one pass through the
-trace that will call the right hooks for the right intervals will be done.
-
-When the traceset read is over for a events request, the traceset_end
-hook is called. It has the responsibility of finishing the drawing if
-some parts still need to be drawn and to show it on the screen (if the
-viewer uses a pixmap buffer).
-
-It can add dotted lines and such visual effects to enhance the user's
-experience.
