On ArchLinux kde plasma + x11, I noticed that if you call setSize, then poll for events, a Resized event gets polled.

I was just curious if it is guaranteed that this will happen. I'm pretty sure it's a side-effect of the event being propagated from the underlying API (window's API, x11, etc...). Is there some sense of guarantee this will happen?

A simple question just reworded:

Is it possible for a MouseButtonPressed event to have different x, and y positions for the mouse's coordinates than the previous MouseMove event?

Answer: Yes

I wrote this small bit of code to familiarize myself with C++ again:

int main() {
  // Crashes if font fails to load
  const sf::Font font = load_font().value();
  sf::RenderWindow window(sf::VideoMode(800, 600), "Game Of Life");
  const sf::Vector2u window_size = window.getSize();

  // UI
  sf::Text title = center_text_origin(sf::Text("Game of Life", font, FONT_SIZE));
  const auto set_title_position = [](sf::Text &title, sf::Vector2u window_size) {
    float amt_push_downwards = title.getLocalBounds().height / 2 + 10;
    sf::Vector2f pos = sf::Vector2f(
        window_size.x / 2.0,

  while (window.isOpen()) {
    sf::Event event;
    while (window.pollEvent(event)) {
      switch (event.type) {
        case sf::Event::Closed:
        case sf::Event::Resized:
            const sf::FloatRect new_window_area(0.f, 0.f, event.size.width, event.size.height);
            const sf::Vector2u new_window_size(rect_size(new_window_area));

            set_title_position(title, new_window_size);


  return 0;

I noticed that my title text does not need to have an initialized position set, as the resize event gets triggered when RenderWindow is initialized. Is this guaranteed? Is this a quirk that may or may not be prevalent in future versions of SFML?

C / When will setSmooth be implemented for Fonts?
« on: July 04, 2022, 08:21:18 am »
What I want is the ability to disable set_smooth in rust-sfml. That's three jumps away from the main repository, but the main repository, thankfully, already has the setSmooth functionality for Fonts https://github.com/SFML/SFML/pull/1690

I read into CSFML, and I'll be honest. I have no clue what is going on. I want to know how doable it is to possibly implement setSmooth for CSFML that way I can help move it to rust-sfml.

Thank you.

Graphics / What is sfml sprite default behavior with undefined texture rect
« on: December 30, 2021, 05:51:04 am »
Here is the example code of what I am curious about:
sprite = sf::Sprite(*assets::missingTexture));

sprite.getLocalBounds() should return a FloatRect with a width and height corresponding to the size of the missingTexture, correct?
Wiki doesn't explain something as specific as this, so I want some confirmation whether this is true or false.

Thank you.
