SFML wiki / Android example can not close on Escape

« on: February 06, 2016, 03:08:46 pm »

Hello,

I try to run android example through wiki "Tutorial: Building SFML for Android".
As was expected it worked.

I added Escape key release checking to close via Back button on the tablet.

if (event.type == sf::Event::KeyReleased)
{
  if (event.key.code == sf::Keyboard::Escape)
  window.close();
}
 

It can not close properly.
Any idea ? What can I do ?

Thanks

Edit:
I noticed same question at this link

Graphics / how to use RenderTexture properly (off-screen drawing) ?

« on: February 17, 2014, 10:46:03 am »

Hello,

I'm trying to use off-screen drawing (in tutorial section "Drawing 2D stuff")

if i don't use set origin and scale it doesn't display properly.

What am I doing wrong?

   
sprite.setOrigin(0, 400);
sprite.scale(1, -1);
 

#include <SFML/Graphics.hpp>
#include <SFML/Window.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(300, 400), "Render Texture");

    sf::RenderTexture rt;
    sf::Sprite sprite;

    rt.create(300, 400);
    //sprite.setOrigin(0, 400);
    //sprite.scale(1, -1);

    sf::RectangleShape rect;
    rect.setPosition(10, 20);
    rect.setSize(sf::Vector2f(50, 100));
    rect.setFillColor(sf::Color(0, 255, 0));
    rt.draw(rect);

    sprite.setTexture(rt.getTexture());
    sprite.setPosition(0, 0);

    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }
        window.clear(sf::Color::Black);
        window.draw(sprite);
        window.display();
    }

    return 0;
}

Graphics / ConvexShape and its getPosition

« on: May 28, 2013, 10:23:05 am »

Hello

I'm trying to make this:

draw(convexshape with 4 points)
getBounds
getPosition
draw(rectangle) //frame arround convex sahpe
 

If convexshape's first coordinate is different from "0" then getPosition returns (pos - firstCoord).

is it normal behaviour ?

rect.setPosition(shape.getPosition());


[/code]

#include <SFML/Graphics.hpp>

int main ()
{
    sf::ConvexShape shape(4);
    shape.setFillColor(sf::Color::Red);

    sf::RectangleShape rect;
    rect.setFillColor(sf::Color::Green);

    shape.setPoint(0, sf::Vector2f(40,50));
    //shape.setPoint(0, sf::Vector2f(0,0));
    shape.setPoint(1, sf::Vector2f(140,60));
    shape.setPoint(2, sf::Vector2f(150,250));
    shape.setPoint(3, sf::Vector2f(30,240));

    shape.setPosition(200, 200);

    rect.setSize(sf::Vector2f(shape.getGlobalBounds().width, shape.getGlobalBounds().height));
    rect.setPosition(shape.getPosition());

    sf::RenderWindow window(sf::VideoMode(800, 600), "ConvexShape");
    sf::Event event;

    while (window.isOpen()) {
        while (window.pollEvent(event)) {
            switch (event.type) {
            case sf::Event::Closed:
                window.close();
                break;
            case sf::Event::KeyPressed:
                window.close();
                break;
            }
        }

        window.clear();
        window.draw(rect);
        window.draw(shape);
        window.display();
    }
}

Network / While data transferring ... How to check progress of transfer?

« on: May 22, 2013, 09:58:37 am »

Hello

I need to display data transfer in a progress bar while data sending/recieving with Ftp/Http.
It is not necessary except big files.

There is a loop in "Ftp::DataChannel::receive"...
But "Ftp::DataChannel::send" method sends data completely at one time.
May be TcpSocket the private member of Ftp  is responsible for this.

My thoughts may tottally be wrong
