AbsoluteLayout

AbsoluteLayout

#include <AbsoluteLayout.hpp>

Inherits: Layout

A layout where children are positioned using absolute coordinates.

AbsoluteLayout allows precise control over widget positioning. Each child’s position is determined by the absX and absY fields in its LayoutSpec.

Advantages:

• Precise control over positioning

• No automatic resizing based on available space

Disadvantages:

• Not responsive to terminal resizing

• Widgets can overlap

• Less maintainable for complex layouts

Example Usage:

auto abs = std::make_shared<Container>(
  std::make_shared<AbsoluteLayout>()
);

auto button1 = std::make_shared<Button>("Top-left");
auto button2 = std::make_shared<Button>("Bottom-right");

// Position at (5, 3)
abs->addChild(button1, LayoutSpec{.absX = cells(5), .absY = cells(3)});

// Position at (20, 15)
abs->addChild(button2, LayoutSpec{.absX = cells(20), .absY = cells(15)});
