Detailed Description

Desktop implementation of the IWindowSystem interface using GLFW.

Provides window creation, event polling, and framebuffer resize handling for standalone desktop environments. This class represents the concrete platform layer for rendering contexts that rely on desktop windowing systems (e.g., Windows, Linux, FreeBSD).

FramebufferResizeCallback()

void rendering_engine::StandaloneDesktopWindow::FramebufferResizeCallback ( GLFWwindow * window, int width, int height )

static

GLFW framebuffer resize callback.

This static function is registered with GLFW to detect when the framebuffer size changes. It sets the internal resize flag for synchronization with the rendering system.

Parameters

window	Pointer to the GLFW window instance.
width	New framebuffer width.
height	New framebuffer height.

Definition at line 69 of file standalone_window_system.cpp.

{
    auto app = reinterpret_cast<StandaloneDesktopWindow*>(glfwGetWindowUserPointer(window));
    app->mFramebufferResized = true;
}

GetApplication()

const IApplication & rendering_engine::StandaloneDesktopWindow::GetApplication ( )

overridevirtual

Retrieves a reference to the owning application instance.

Returns

Reference to the associated IApplication object.

Implements rendering_engine::IWindowSystem.

Definition at line 64 of file standalone_window_system.cpp.

{
    return mApp;
}

GetFullScreenResolution()

WindowResolution rendering_engine::StandaloneDesktopWindow::GetFullScreenResolution ( ) const

overridevirtual

Queries the resolution of the full-screen display mode.

Returns

The native screen resolution when running in full-screen mode.

Implements rendering_engine::IWindowSystem.

Definition at line 75 of file standalone_window_system.cpp.

{
    return mFullScreenRes;
}

GetNativeHandle()

void * rendering_engine::StandaloneDesktopWindow::GetNativeHandle ( ) const

overridevirtual

Returns a pointer to the underlying native window handle.

Returns

Platform-specific native handle (e.g., HWND, GLFWwindow*, X11 Window).

Implements rendering_engine::IWindowSystem.

Definition at line 53 of file standalone_window_system.cpp.

{
    return static_cast<void*>(mWindow);
}

IsFramebufferResized()

bool rendering_engine::StandaloneDesktopWindow::IsFramebufferResized ( ) const

inlineoverridevirtual

Checks if the framebuffer has been resized since the last frame.

Implements rendering_engine::IWindowSystem.

Definition at line 48 of file standalone_window_system.hpp.

{ return mFramebufferResized; }

PollEvents()

void rendering_engine::StandaloneDesktopWindow::PollEvents ( )

overridevirtual

Polls and processes OS-level window events (input, resize, close, etc.).

Implements rendering_engine::IWindowSystem.

Definition at line 43 of file standalone_window_system.cpp.

{
    glfwPollEvents();
}

ResetFramebufferResizedFlag()

void rendering_engine::StandaloneDesktopWindow::ResetFramebufferResizedFlag ( )

inlineoverridevirtual

Resets the framebuffer resized flag after handling a resize event.

Implements rendering_engine::IWindowSystem.

Definition at line 50 of file standalone_window_system.hpp.

{ mFramebufferResized = false; }

ShouldClose()

bool rendering_engine::StandaloneDesktopWindow::ShouldClose ( ) const

overridevirtual

Checks whether the user has requested to close the window.

Implements rendering_engine::IWindowSystem.

Definition at line 48 of file standalone_window_system.cpp.

{
    return glfwWindowShouldClose(mWindow);
}

Shutdown()

void rendering_engine::StandaloneDesktopWindow::Shutdown ( )

overridevirtual

Performs cleanup and releases window-related resources.

Implements rendering_engine::IWindowSystem.

Definition at line 58 of file standalone_window_system.cpp.

{
    glfwDestroyWindow(mWindow);
    glfwTerminate();
}
