NAME

XSelectInput - select input events  

SYNOPSIS

XSelectInput(display, w, event_mask) Display *display; Window w; long event_mask;
 

ARGUMENTS

Specifies the connection to the X server. Specifies the event mask. Specifies the window whose events you are interested in.
 

DESCRIPTION

The XSelectInput 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 closest ancestor that is interested, unless the do_not_propagate mask prohibits 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 CirculateRequest, ConfigureRequest, or MapRequest events, which are associated with the event mask SubstructureRedirectMask. Only one client at a time can select a ResizeRequest event, which is associated with the event mask ResizeRedirectMask. Only one client at a time can select a ButtonPress event, which is associated with the event mask ButtonPressMask.

The server reports the event to all interested clients.

XSelectInput can generate a BadWindow error.
 

DIAGNOSTICS

A value for a Window argument does not name a defined Window.
