RootElement

The guikit::RootElement is the root of the widget tree. Every Window creates one automatically and exposes it via Window::rootElement. It fills the entire window, draws the background color, and lays out all of its children.

It inherits from Element, so everything in the Element reference is available.

Fields

background

The background color of the root.

Color background;

Constructor

RootElement(Renderer *renderer, float width, float height)

Creates a root element with a fixed width and height. In normal usage you never construct this directly - the Window does it for you.

RootElement(Renderer *renderer, float width, float height);

Destructor

~RootElement()

Destroys the root element.

~RootElement();

Overrides

render()

Fills the window with background, then renders all children. Called every frame by the Window render loop.

void render();

Example

#include <guikit/window.hpp>
#include <guikit/box.hpp>
#include <guikit/colors.hpp>

using namespace guikit;

int main() {
    Window window("Root Demo", 800, 600);

    window.rootElement->addChild<Box>()
        .setBackgroundColor(Colors::Teal500())
        .setWidth(300)
        .setHeight(150);

    window.show();
    return 0;
