#include "UltraEngine.h"

using namespace UltraEngine;

int main(int argc, const char* argv[])
{
    //Get the displays

    //Create a window
    auto window = CreateWindow("Ultra Engine", 0, 0, 640, 480, displays[0], WINDOW_TITLEBAR | WINDOW_CENTER);

    //Create User Interface
    auto ui = CreateInterface(window);

    //Create buttons
    int x = (window->ClientSize().x - 120) / 2;
    int y = 50;
    int sep = 40;

    auto button = CreateButton("Button", x, y, 120, 30, ui->root);
    y += sep;

    auto toggle = CreateButton("Toggle", x, y, 120, 30, ui->root, BUTTON_TOGGLE);
    y += sep;

    auto toolbar = CreateButton("Toolbar", x, y, 120, 30, ui->root, BUTTON_TOOLBAR);
    y += sep;

    auto checkbox = CreateButton("Checkbox", x, y, 120, 30, ui->root, BUTTON_CHECKBOX);
    y += sep;

    auto radio1 = CreateButton("Option 1", x, y, 120, 30, ui->root, BUTTON_RADIO);
    radio1->SetState(WIDGETSTATE_SELECTED);
