FLTK High-Level API Common Types

This module provides common types and aliases for the high-level FLTK API. It re-exports and renames types from the low-level bindings to provide a cleaner, more D-idiomatic interface without the Fl prefix.

Types 5

structRect

Represents a rectangular region with position and size.

This is a convenience type for working with widget geometry.

Fields

int xX coordinate (left edge)

int yY coordinate (top edge)

int widthWidth in pixels

int heightHeight in pixels

Methods

int right() const @safe nothrow @nogcReturns the right edge coordinate.

int bottom() const @safe nothrow @nogcReturns the bottom edge coordinate.

bool contains(int px, int py) const @safe nothrow @nogcChecks if a point is inside the rectangle.

bool intersects(Rect other) const @safe nothrow @nogcChecks if this rectangle intersects with another.

Constructors

this(int x, int y, int width, int height)Creates a rectangle from position and size.

structSize

Represents a size with width and height.

Fields

int widthWidth in pixels

int heightHeight in pixels

Methods

int area() const @safe nothrow @nogcCalculates the area.

Constructors

this(int width, int height)Creates a size.

structPoint

Represents a 2D point.

Fields

int xX coordinate

int yY coordinate

Methods

double distanceTo(Point other) const @safe nothrow @nogcCalculates distance to another point.

Constructors

this(int x, int y)Creates a point.

aliasCallback = void delegate()

Callback delegate type for widget events.

This is the standard callback signature for widget interactions.

aliasCallbackWithData = void delegate(void * data)

Callback delegate type for widget events with user data.

Parameters

data User-provided data pointer
