ClosureExpression

An expression using a custom GClosure to compute the value from its parameters.

class ClosureExpression : Expression {

GtkClosureExpression* gtkClosureExpression;

GtkClosureExpression* getClosureExpressionStruct(bool transferOwnership);

void* getStruct();

this(GtkClosureExpression* gtkClosureExpression, bool ownedRef);

static GType getType();

this(GType valueType, Closure closure, Expression[] params);

}

Constructors

this this(GtkClosureExpression* gtkClosureExpression, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(GType valueType, Closure closure, Expression[] params): Creates a GtkExpression that calls closure when it is evaluated. closure is called with the this object and the results of evaluating the params expressions.
