NAME

THWMouse - internal low-level hardware mouse backend

SYNOPSIS

use TUI::Drivers::HWMouse;

# Internal backend usage only:
THWMouse->resume();
THWMouse->suspend();

DESCRIPTION

THWMouse implements low-level mouse handling for the TVision driver layer.

This module is an internal backend API. External code should use TMouse as the public mouse interface.

The module maintains global mouse state and backend hooks used by the driver stack.

THWMouse is not an object-oriented class. It must not be instantiated. All interaction is performed through class method calls.

Mouse handling is initialized automatically when the module is loaded and is suspended automatically when the program terminates.

The behavior and internals here are backend-focused and may change as the driver implementation evolves. Public callers should depend on TMouse instead.

VARIABLES

$buttonCount

Contains the number of mouse buttons (PositiveOrZeroInt) detected on the system.

$handlerInstalled

Indicates whether the mouse event handler is currently installed (Bool).

$noMouse

Indicates whether mouse hardware is available (Bool).

$mouseRangeX

Maximum X coordinate for mouse movement (PositiveOrZeroInt).

$mouseRangeY

Maximum Y coordinate for mouse movement (PositiveOrZeroInt).

METHODS

The backend exposes class methods with the same operational surface used by TMouse (for example show(), hide(), getEvent(), present(), resume(), and suspend()).

Their public-facing semantics are documented in TMouse.
