static gboolean event_callback ( XEvent *  event,
gpointer  data 
) [static]

This is the most important function in the whole program.

It is the heart, it is the nexus, it is the Grand Central Station of Metacity's world. When we create a MetaDisplay, we ask GDK to pass *all* events for *all* windows to this function. So every time anything happens that we might want to know about, this function gets called. You see why it gets a bit busy around here. Most of this function is a ginormous switch statement dealing with all the kinds of events that might turn up.

Parameters:
event The event that just happened
data The MetaDisplay that events are coming from, cast to a gpointer so that it can be sent to a callback

MetaDisplay* meta_display_for_x_display ( Display *  xdisplay  ) 

Returns the singleton MetaDisplay if "xdisplay" matches the X display it's managing; otherwise gives a warning and returns NULL.

When we were claiming to be able to manage multiple displays, this was supposed to find the display out of the list which matched that display. Now it's merely an extra sanity check.

Parameters:
xdisplay An X display
Returns:
The singleton X display, or NULL if "xdisplay" isn't the one we're managing.

void meta_set_syncing ( gboolean  setting  ) 

A handy way to turn on synchronisation on or off for every display.

Bug:
Of course there is only one display ever anyway, so this can be rather hugely simplified.

gboolean dump_events = TRUE [static]

Definition at line 1063 of file display.c.

gboolean is_syncing = FALSE [static]

Stores whether syncing is currently enabled.

Definition at line 3971 of file display.c.

MetaDisplay* the_display = NULL [static]

The display we're managing.

This is a singleton object. (Historically, this was a list of displays, but there was never any way to add more than one element to it.) The goofy name is because we don't want it to shadow the parameter in its object methods.
