Window / qt5 widgetHandle -> SFML2.0

« on: September 26, 2016, 12:51:09 pm »

Hi I am trying to setup a QTSFMLCanvas as seen in eg: http://becomingindiedev.blogspot.se/2013/10/qt-5-and-sfml-20-integration.html

Qt5-widget has a winId() method that is supposed to return the native handler for the widget. On my platform (linux Arch 64bit) it is a long long unsigned int and RenderWindow seems to want a long unsigned int.

hence,
RenderWindow::create(reinterpret_cast<sf::WindowHandle>(winId()));

fails with: invalid cast from type 'WId {aka long long unsigned int}' to type 'sf::WindowHandle {aka long unsigned int}'

Is there a workaround or a way to convert the handle? I have been giving google hard time with this one and have found nothing.

static_cast just hangs the application.

Any ideas?

Graphics / rotate around different origins

« on: December 25, 2013, 10:37:24 pm »

Hi,
I have a sf::Drawable that has a sprite that draws a sf::Sprite at 0,0 and it has a specified orgin set. eg. center of the sprite.

From time to time I'd like to rotate the sprite around another origin. Is there a way to do this withouth having to transform the object back and forth. As soon as I change the origin of the sprite it moves since the 0,0 will now have the new position.

System / no KeyEvents in wxWidget

« on: February 12, 2013, 10:24:01 pm »

Hi,
is it known that no KeyEvents are triggered when using SFML with wxWidget?
I am polling the event in a mainloop like this:

   sf::Event event;
   while (window.pollEvent(event))
   {
      if (event.type == sf::Event::KeyPressed) {
         LOG << "Yeah!\n";
      }
   }
 

however the polling the Keyboard directly is still possible.
Is there a workaround to get the KeyEvent working?

Graphics / Sprite composition and transformation

« on: January 08, 2013, 08:07:18 pm »

Is this possible...

Let's say I have a class that extends sf::Sprite and implements void draw(sf::RenderTarget& target, sf::RenderStates states).
And in draw(..) I render a couple of sprites that move and what not.

is it possible to do a setPosition of the class and have the rendered content translate accordingly?

What is the correct way of doing this?

Graphics / Drawing vertexarrays always start from 0,0

« on: January 05, 2013, 02:49:35 am »

Hi,
I don't know if I am missing something but when I try to draw lines using a sf::VertexArray it always starts drawing from (0,0).
So let's say I choose to draw a box with theese coords:

(10,10)
(110,10)
(110,110)
(10,110)

I have attached an image of the result.
Running SFML2.0 on a LinuxBox.

Is this the desired result or a bug? And is there a workaround?
