XSelectInput(3X11) X11R5 XSelectInput(3X11)NAMEXSelectInput - select input events
SYNTAX
XSelectInput(display, w, event_mask)
Display *display;
Window w;
long event_mask;
ARGUMENTS
display Specifies the connection to the X server.
event_mask
Specifies the event mask.
w Specifies the window whose events you are interested in.
DESCRIPTION
The function requests that the X server report the events associated
with the specified event mask. Initially, X will not report any of
these events. Events are reported relative to a window. If a window
is not interested in a device event, it usually propagates to the clos‐
est ancestor that is interested, unless the do_not_propagate mask pro‐
hibits it.
Setting the event-mask attribute of a window overrides any previous
call for the same window but not for other clients. Multiple clients
can select for the same events on the same window with the following
restrictions:
· Multiple clients can select events on the same window because
their event masks are disjoint. When the X server generates an
event, it reports it to all interested clients.
· Only one client at a time can select or events, which are associ‐
ated with the event mask
· Only one client at a time can select a event, which is associated
with the event mask
· Only one client at a time can select a event, which is associated
with the event mask
The server reports the event to all interested clients.
can generate a error.
DIAGNOSTICS
A value for a Window argument does not name a defined Window.
