Method

GtkExpressionbind

Declaration [src]

GtkExpressionWatch*
gtk_expression_bind (
  GtkExpression* self,
  GObject* target,
  const char* property,
  GObject* this_
)

Description [src]

Bind targets property named property to self.

The value that self evaluates to is set via g_object_set() on target. This is repeated whenever self changes to ensure that the object’s property stays synchronized with self.

If selfs evaluation fails, targets property is not updated. You can ensure that this doesn’t happen by using a fallback expression.

Note that this function takes ownership of self. If you want to keep it around, you should gtk_expression_ref() it beforehand.
