Constructor Details

CClosureExpression

public CClosureExpression(MemorySegment address)

Create a CClosureExpression instance for the provided memory address.

Parameters:

address - the memory address of the native object

CClosureExpression

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

Creates a GtkExpression that calls callback_func when it is evaluated.

This function is a variant of ClosureExpression(Type, Closure, 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 @Nullable Type getType()

Get the GType of the CClosureExpression class.

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected CClosureExpression asParent()

Return this instance as if it were its parent type. Comparable to the Java super keyword, but ensures the parent typeclass is also used in native code.

Overrides:

asParent in class Expression

Returns:

the instance as if it were its parent type
