Detailed Description

Main application class that orchestrates the application lifecycle.

The Application class follows the Single Responsibility Principle by delegating window management to WindowManager and UI rendering to UIRenderer. It focuses on high-level orchestration, state management, and business logic.

The Application class coordinates all major subsystems:

• WindowManager: GLFW window creation and event handling
• UIRenderer: ImGui rendering and UI logic
• ConfigManager: JSON-based configuration persistence
• Logger: Thread-safe logging system
• DialogManager: Reusable dialog components
• UpdateChecker: Asynchronous update notifications
• Localization: Multi-language support

Usage Example

int main() {
    MetaImGUI::Application app;
    if (!app.Initialize()) {
        return 1;
    }
    app.Run();  // Blocks until application closes
    app.Shutdown();
    return 0;
}

Member Function Documentation

Initialize()

bool MetaImGUI::Application::Initialize

(

)

Initialize the application and all subsystems.

Initializes all components in the correct order:

1. Logger system
2. Configuration manager (loads settings)
3. Localization system (loads translations)
4. Window manager (creates GLFW window)
5. UI renderer (initializes ImGui)
6. Dialog manager
7. Update checker (starts async update check)

Returns

true if all subsystems initialized successfully, false otherwise

Note

Must be called before Run()

Run()

void MetaImGUI::Application::Run

(

)

Run the main application loop.

Enters the main event loop which continues until the window is closed. The loop processes:

• Window events (resize, input, etc.)
• ImGui frame rendering
• Application logic updates

Note

This method blocks until the application is closed

Must be called after successful Initialize()

ShouldClose()

bool MetaImGUI::Application::ShouldClose

(

)

const

Check if the application should close.

Returns

true if the application should close

Shutdown()

void MetaImGUI::Application::Shutdown

(

)

Shutdown the application and cleanup resources.

Performs graceful shutdown of all subsystems in reverse order:

• Saves configuration (window size, preferences)
• Destroys update checker
• Destroys dialog manager
• Destroys UI renderer
• Destroys window manager
• Destroys configuration manager
• Shuts down logger

Note

Safe to call multiple times

Automatically called by destructor if not called explicitly
