Hi there,

I'm doing a little test for my GUI system, where I have a sf::RectangleShape that is acting as an edit box. I'm trying to center the text directly on that rectangle shape, but whenever I call my centerText() method for the first time (whenever a person inputs a character for the first time) it changes the rectangle's position a little bit to the left and up, then works perfectly. Sorry if this is a little confusing but here's my code:

sf::RectangleShape m_box;
sf::Text m_text_drawn;

void EditBox::handleTextEvent(sf::Uint32 character)
    {
        if (!getInWidget() || !getVisible())
            return;

        if (character == 8)
        {
            if (!m_user_text.isEmpty())
                m_user_text.erase(m_user_text.getSize() - 1);

            return;
        }

        if (character < 127)
            m_user_text += character;

        centerText();
    }

void EditBox::centerText()
    {
        m_box.setOrigin(m_box.getGlobalBounds().width / 2, m_box.getGlobalBounds().height / 2);

        m_text_drawn.setOrigin(m_text_drawn.getGlobalBounds().width / 2, m_text_drawn.getGlobalBounds().height / 2);
        m_text_drawn.setPosition(m_box.getPosition());
    }

Thanks!

Don't forget the 'left' and 'top' members of getGlobalBounds(). For text, they aren't 0 by default (or something) if I remember correctly.

^ that

Also, make sure you're not updating the position as text is entered as it will affect the vertical based on characters entered.
