Graphics / Re: sf::text size and 'highlighting'.

« on: January 16, 2014, 09:22:46 pm »

Thanks for the replies!
Ive found something that works, although i'm not completely sure how. I guess whats referred to as the 'baseline' in the documentation is the bottom of the text bounding box.

static sf::Font font;
    font.loadFromFile("fonts/Arial.ttf");
   
    sf::Text text(string, font, 30);
    text.setColor(fgColour);
    text.setPosition(x, y*text.getGlobalBounds().height-text.getGlobalBounds().top);
   
    int c = 0;
        while(string[c]!='\0') {
            sf::RectangleShape rect;
            rect.setPosition(text.findCharacterPos(c).x+font.getGlyph(string[c], 30, 0).bounds.left, text.getGlobalBounds().top+(text.getGlobalBounds().height+font.getGlyph(string[c], 30, 0).bounds.top));
            rect.setSize(sf::Vector2f(font.getGlyph(string[c], 30, 0).bounds.width, font.getGlyph(string[c], 30, 0).bounds.height));
            rect.setFillColor(bgColour);
            window->draw(rect);
            c++;
        }
   
    window->draw(text);

Graphics / sf::text size and 'highlighting'.

« on: January 13, 2014, 06:51:45 pm »

Hello 

I am trying to write a basic function for printing highlighted text to the screen. Eventually I wont be loading the font every time I want to print text, but this is just a test:

void mvprintsp(sf::RenderWindow* window, const char* string, const int x, const int y, sf::Color fgColour, sf::Color bgColour){
   
    static sf::Font font;
    font.loadFromFile("fonts/Courier New Bold.ttf");
   
    sf::Text text(string, font, 24);
    text.setColor(fgColour);
    text.setPosition(x, y*text.getGlobalBounds().height-text.getGlobalBounds().top);
   
    sf::RectangleShape rectangle(sf::Vector2f(text.getGlobalBounds().width, text.getGlobalBounds().height));
    rectangle.setPosition(text.getGlobalBounds().left, text.getGlobalBounds().top);
    rectangle.setFillColor(bgColour);

    window->draw(rectangle);
    window->draw(text);
}

But this doesn’t work. The background rectangle is not high enough, and some characters (capital 'A') stick out the side of the highlighted area. I thought It might have something to do with each character having different coordinates so I tried this:

int c = 0;
int offsetY=0;
while(string[c]!='\0') {
    if(text.findCharacterPos(c).y>y*24){
        offsetY=y*24-text.findCharacterPos(c).y;
    }
    c++;
}
rectangle.setSize(sf::Vector2f(text.getGlobalBounds().width, text.getGlobalBounds().height+offsetY));

But that didn’t change anything. This is what I get:



There must be something i'm not getting here. 
Any help would be appreciated.
