#include <splitgui/graphics.hpp>
#include <splitgui/structs.hpp>

#include <fstream>
#include <sstream>
#include <string>

int main(void) {

    std::ifstream indexFile("index.xml");

    if (!indexFile.is_open()) {
        printf("ERROR: error opening index.xml\n");
        return -1;
    }

    std::stringstream buffer;
    buffer << indexFile.rdbuf();
    std::string page = buffer.str();

    SplitGui::EventHandler eventHandler;

    window.attachEventHandler(eventHandler);

    SplitGui::VulkanFlags vulkanFlags;
    vulkanFlags.enableValidationLayers = true;

    SplitGui::Graphics graphics;

    graphics.submitWindow(window);
    graphics.attachEventHandler(eventHandler);

    SplitGui::RectObj viewport;
    viewport.size = window.getSize();
    viewport.x    = 0;
    viewport.y    = 0;
    
    SplitGui::Interface ui;
    TRYRC(parseRes, ui.parseXml(page));
