Constructor Details

CClosureExpression

public CClosureExpression(MemorySegment address)

Create a CClosureExpression proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

CClosureExpression

public CClosureExpression(Type valueType,
 @Nullable
 @Nullable ClosureMarshal marshal,
 Expression[] params,
 Callback callbackFunc,
 @Nullable
 @Nullable ClosureNotify userDestroy)

Creates a GtkExpression that calls callback_func when it is evaluated.

This function is a variant of ClosureExpression(org.gnome.glib.Type, org.gnome.gobject.Closure, org.gnome.gtk.Expression[]) that creates a GClosure by calling g_cclosure_new() with the given callback_func, user_data and user_destroy.

Parameters:

valueType - the type of the value that this expression evaluates to

marshal - marshaller used for creating a closure

params - expressions for each parameter

callbackFunc - callback used for creating a closure

userDestroy - destroy notify for userData

Method Details

getType

public static Type getType()

Get the GType of the CClosureExpression class

Returns:

the GType

asParent

protected CClosureExpression asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class Expression
