That did the trick, Thanks!

The box is just an simplified example, any arbitrary shape drawn this way will start off from (0,0).

   sf::VertexArray lines(sf::LinesStrip, m_Verts.size()+1);
   std::vector<sf::Vector2<float> >::const_iterator it = m_Verts.begin();
   for(;it!=m_Verts.end();++it) {
      lines.append(sf::Vertex(*it, sf::Color(255,255,255,255)));
   }
   lines.append(sf::Vertex(m_Verts[0], sf::Color(255,255,255,255)));
   target.draw(lines);

 

and m_Verts is fed like this

   m_Verts.push_back(sf::Vector2f(10,10));
   m_Verts.push_back(sf::Vector2f(110,10));
   m_Verts.push_back(sf::Vector2f(110,110));
   m_Verts.push_back(sf::Vector2f(10,110));

 

This example out of context may seem like a detour though

Graphics / Drawing vertexarrays always start from 0,0

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?

Window / Re: Resizing (Qt) does not work

« on: April 15, 2012, 10:17:26 am »

   

Code: [Select]

    sf::View view = sf::View(sf::FloatRect(0,0,w,h));
    float a = h/(initialHeight*2);
    view.SetViewport(sf::FloatRect(0,(-a+1),w/initialWidth,h/initialHeight));
    sf::RenderWindow::SetView(view);
Where initialSizes are the initial-size of the wxPanel, as specified in ctor.
Please, give feedback to this solution, since the "a" was created empirically. Works like a charm though.

Thanks,

I followed your lead about the viewport. And It is possible, atleast in wxWidget, to resize to PanelSize(wxWidget) by updating both the view and viewport, to get rid of the clipping that is restricted to initial size of widget. So there is no need to call Create() on resize-handler, which is inefficient and fails for wxWidgets. Perhaps this is also true for Qt ?

Now when I resize the window / panel, I maintain coord(0,0) in top/left corner and maintain pixelsize (no streching).

Viewport of the sf::Renderwindow?

Hi,

Seems like re-creating the context/window seems to be the only solution for this. I have the same problem with running SFML-context in a wxWidget-Panel. But there seems to be a bug...

When I call upon sf::Window::Create( getSystemHandle() )  in the resizeHandler, I get this funny graphical artifact. (see attachment )


...where it seems like all textures are random-memory.
Please, need help figuring out a solution for this. Do I have to reload every texture?

Btw, using SFML2.0/ArchLinux/ATI
