Method Details

getType

public static @Nullable Type getType()

Get the GType of the ExpressionWatch class

the GType

evaluate

public boolean evaluate(Value value)

Evaluates the watched expression and on success stores the result in value.

This is equivalent to calling Expression.evaluate(org.gnome.gobject.GObject, org.gnome.gobject.Value) with the expression and this pointer originally used to create watch.

Parameters:

value - an empty GValue to be set

Returns:

TRUE if the expression could be evaluated and value was set

ref

public ExpressionWatch ref()

Acquires a reference on the given GtkExpressionWatch.

Returns:

the GtkExpressionWatch with an additional reference

unref

public void unref()

Releases a reference on the given GtkExpressionWatch.

If the reference was the last, the resources associated to self are freed.

unwatch

public void unwatch()

Stops watching an expression.

See Expression.watch(org.gnome.gobject.GObject, org.gnome.gtk.ExpressionNotify) for how the watch was established.
