The last two posts built the abstract factory pattern piece by piece. This post is the reference: the whole project, as real files in real folders.
main.cpp
#include <iostream>
#include "theme/UIFactory.h"
#include "theme/LightThemeFactory.h"
#include "theme/DarkThemeFactory.h"
void renderScreen(UIFactory& factory) {
auto button = factory.createButton();
auto label = factory.createLabel();
std::cout << button->render() << "\n";
std::cout << label->render() << "\n";
}
int main() {
std::cout << "Light theme:\n";
LightThemeFactory light;
renderScreen(light);
std::cout << "Dark theme:\n";
DarkThemeFactory dark;
renderScreen(dark);
return 0;
