Two different masks, structure_notify
and substructure_notify
select essentially the same set of events, except that in the first
case, the user gets the events that occur in the Window and
in the second, the events that occur in its subwindows.
To accommodate this, the event specification has an extra argument,
whose value is either self
or child
. If omitted, it defaults
to self
, except for the case of create_notify
as explained
below.
Remember that registering a callback for any of these events means that the Window will also be getting the others.
Circulate Notify Event.
The server generates a circulate_notify
event when a window is
restacked.
To receive this event when the window itself is affected, specify either:
circulate_notify circulate_notify(self)
To receive this event when a child window is affected, specify:
circulate_notify(child)
Configure Notify Event.
The server generates a configure_notify
event when there is
any change to a window's configuration, i.e. position, size,
etc.
To receive this event when the window itself is affected, specify either:
configure_notify configure_notify(self)
To receive this event when a child window is affected, specify:
configure_notify(child)
Destroy Notify Event.
The server generates a destroy_notify
event when a window is
destroyed.
To receive this event when the window itself is affected, specify either:
destroy_notify destroy_notify(self)
To receive this event when a child window is affected, specify:
destroy_notify(child)
Gravity Notify Event.
The server generates a gravity_notify
event when a window is moved
because its parent's size changed.
To receive this event when the window itself is affected, specify either:
gravity_notify gravity_notify(self)
To receive this event when a child window is affected, specify:
gravity_notify(child)
Map Notify Event.
The server generates a map_notify
event when a window changes
state from unmapped to mapped.
To receive this event when the window itself is affected, specify either:
map_notify map_notify(self)
To receive this event when a child window is affected, specify:
map_notify(child)
Unmap Notify Event.
The server generates an unmap_notify
event when a window changes
state from mapped to unmapped.
To receive this event when the window itself is affected, specify either:
unmap_notify unmap_notify(self)
To receive this event when a child window is affected, specify:
unmap_notify(child)
Reparent Notify Event.
The server generates a reparent_notify
event when the parent of
a window changes.
To receive this event when the window itself is affected, specify either:
reparent_notify reparent_notify(self)
To receive this event when a child window is affected, specify:
reparent_notify(child)
Create Notify Event.
The server generates a create_notify
event when a window is created.
A newly created window does not receive this event, its parent does.
Specify with either:
create_notify create_notify(child)
