Detailed Description

Manages ImGui contexts for UI rendering.

This class initializes and manages ImGui contexts for rendering UI elements in two modes: the main application (using IWindowManager for playfield, backglass, and DMD windows) and standalone initial configuration (using a single SDL window and renderer). It handles SDL event processing and ImGui rendering, integrating with IConfigService for settings.

Constructor & Destructor Documentation

ImGuiManager() [1/2]

ImGuiManager::ImGuiManager	(	IWindowManager *	windowManager,
		IConfigService *	configService
	)

Constructs a ImGuiManager for the main application.

Initializes the ImGui context for the main application using the provided window manager and configuration service.

Parameters

windowManager	The window manager for accessing SDL windows and renderers.
configService	The configuration service for accessing settings.

ImGuiManager() [2/2]

ImGuiManager::ImGuiManager	(	SDL_Window *	window,
		SDL_Renderer *	renderer,
		IConfigService *	configService
	)

Constructs a ImGuiManager for standalone initial configuration.

Initializes the ImGui context for initial configuration using a single SDL window and renderer, with the provided configuration service.

Parameters

window	The SDL window for the configuration UI.
renderer	The SDL renderer for the configuration UI.
configService	The configuration service for accessing settings.

~ImGuiManager()

ImGuiManager::~ImGuiManager

(

)

Destroys the ImGuiManager instance.

Cleans up the ImGui context and any associated resources.

Member Function Documentation

initialize()

void ImGuiManager::initialize

(

)

Initializes the ImGui context.

Sets up the ImGui context for rendering, configuring it for the main application or initial configuration mode.

Here is the call graph for this function:

Here is the caller graph for this function:

newFrame()

void ImGuiManager::newFrame

(

)

Starts a new ImGui frame.

Prepares ImGui for a new rendering frame, updating internal state for UI elements.

Here is the call graph for this function:

processEvent()

void ImGuiManager::processEvent

(

const SDL_Event &

event

)

Processes an SDL event for ImGui.

Forwards the provided SDL event to ImGui for handling UI interactions (e.g., mouse clicks, keyboard input).

Parameters

event

The SDL event to process.

reinitialize()

void ImGuiManager::reinitialize

(

)

Reinitialize ImGui platform/renderer backends when windows or renderers change.

If the ImGui context is already created, this will shutdown the SDL/renderer backends and reinitialize them against the current window/renderer provided by the IWindowManager or the stored config window/renderer.

Here is the call graph for this function:

render()

void ImGuiManager::render

(

SDL_Renderer *

renderer

)

Renders ImGui draw data.

Renders the ImGui UI elements to the specified SDL renderer.

Parameters

renderer

The SDL renderer to use for rendering ImGui draw data.
