.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 .
