PointerInterface

public class FileMonitor
extends PropertyHolder

Monitors a file or directory for changes.

To obtain a `GFileMonitor` for a file or directory, use
[method@Gio.File.monitor], [method@Gio.File.monitor_file], or
[method@Gio.File.monitor_directory].

To get informed about changes to the file or directory you are
monitoring, connect to the [signal@Gio.FileMonitor::changed] signal. The
signal will be emitted in the thread-default main context (see
[method@GLib.MainContext.push_thread_default]) of the thread that the monitor
was created in (though if the global default main context is blocked, this
may cause notifications to be blocked even if the thread-default
context is still running).

FileMonitor

public FileMonitor(PointerContainer pointer)

Methodendetails

getClassHandler

public static ClassHandler getClassHandler()

cancel

public boolean cancel()

Cancels a file monitor.

Gibt zurück:

always %TRUE

emitEvent

public void emitEvent(@Nonnull
 File child,
 @Nonnull
 File other_file,
 int event_type)

Emits the #GFileMonitor::changed signal if a change
has taken place. Should be called from file monitor
implementations only.

Implementations are responsible to call this method from the
thread-default main context (see [method@GLib.MainContext.push_thread_default])
of the thread that the monitor was created in.

Parameter:

child - a #GFile.

other_file - a #GFile.

event_type - a set of #GFileMonitorEvent flags.

isCancelled

public boolean isCancelled()

Returns whether the monitor is canceled.

Gibt zurück:

%TRUE if monitor is canceled. %FALSE otherwise.

setRateLimit

public void setRateLimit(int limit_msecs)

Sets the rate limit to which the @monitor will report
consecutive change events to the same file.

Parameter:

limit_msecs - a non-negative integer with the limit in milliseconds to poll for changes

onChanged

public SignalHandler onChanged(FileMonitor.OnChanged signal)

Connect to signal "changed".
See FileMonitor.OnChanged.onChanged(ch.bailu.gtk.gio.File, ch.bailu.gtk.gio.File, int) for signal description.
Field SIGNAL_ON_CHANGED contains original signal name and can be used as resource reference.

Parameter:

signal - callback function (lambda).

Gibt zurück:

SignalHandler. Can be used to disconnect signal and to release callback function.

getTypeID

public static long getTypeID()

getParentTypeID

public static long getParentTypeID()

getTypeSize

public static TypeSystem.TypeSize getTypeSize()

getParentTypeSize

public static TypeSystem.TypeSize getParentTypeSize()

getInstanceSize

public static int getInstanceSize()
