+.LP
+When you receive these events,
+their structure members are set as follows.
+.LP
+The type member is set to the event type constant name that uniquely identifies
+it.
+For example, when the X server reports a
+.ZN GraphicsExpose
+event to a client application, it sends an
+.ZN XGraphicsExposeEvent
+structure with the type member set to
+.ZN GraphicsExpose .
+The display member is set to a pointer to the display the event was read on.
+The send_event member is set to
+.ZN True
+if the event came from a
+.ZN SendEvent
+protocol request.
+The serial member is set from the serial number reported in the protocol
+but expanded from the 16-bit least-significant bits to a full 32-bit value.
+The window member is set to the window that is most useful to toolkit
+dispatchers.
+.LP
+These structures have the following common members:
+window, root, subwindow, time, x, y, x_root, y_root, state, and same_screen.
+The window member is set to the window on which the
+event was generated and is referred to as the event window.
+As long as the conditions previously discussed are met,
+this is the window used by the X server to report the event.
+The root member is set to the source window's root window.
+The x_root and y_root members are set to the pointer's coordinates
+relative to the root window's origin at the time of the event.
+.LP
+The same_screen member is set to indicate whether the event
+window is on the same screen
+as the root window and can be either
+.ZN True
+or
+.ZN False .
+If
+.ZN True ,
+the event and root windows are on the same screen.
+If
+.ZN False ,
+the event and root windows are not on the same screen.
+.LP
+If the source window is an inferior of the event window,
+the subwindow member of the structure is set to the child of the event window
+that is the source window or the child of the event window that is
+an ancestor of the source window.
+Otherwise, the X server sets the subwindow member to
+.ZN None .
+The time member is set to the time when the event was generated
+and is expressed in milliseconds.
+.LP
+If the event window is on the same screen as the root window,
+the x and y members
+are set to the coordinates relative to the event window's origin.
+Otherwise, these members are set to zero.
+.LP
+The state member is set to indicate the logical state of the pointer buttons
+and modifier keys just prior to the event,
+which is the bitwise inclusive OR of one or more of the
+button or modifier key masks:
+.ZN Button1Mask ,
+.ZN Button2Mask ,
+.ZN Button3Mask ,
+.ZN Button4Mask ,
+.ZN Button5Mask ,
+.ZN ShiftMask ,
+.ZN LockMask ,
+.ZN ControlMask ,
+.ZN Mod1Mask ,
+.ZN Mod2Mask ,
+.ZN Mod3Mask ,
+.ZN Mod4Mask ,
+and
+.ZN Mod5Mask .
+.LP
+Each of these structures also has a member that indicates the detail.
+For the
+.ZN XKeyPressedEvent
+and
+.ZN XKeyReleasedEvent
+structures, this member is called a keycode.
+It is set to a number that represents a physical key on the keyboard.
+The keycode is an arbitrary representation for any key on the keyboard
+(see sections 12.7 and 16.1).
+.LP
+For the
+.ZN XButtonPressedEvent
+and
+.ZN XButtonReleasedEvent
+structures, this member is called button.
+It represents the pointer button that changed state and can be the
+.ZN Button1 ,
+.ZN Button2 ,
+.ZN Button3 ,
+.ZN Button4 ,
+or
+.ZN Button5
+value.
+For the
+.ZN XPointerMovedEvent
+structure, this member is called is_hint.
+It can be set to
+.ZN NotifyNormal
+or
+.ZN NotifyHint .
