Window / [HOWTO] Make Transparent SFML Window (on Windows 7+)
« on: November 14, 2016, 03:00:12 am »
It got asked multiple times here in the forums, and I've finally found THE solution after a lot of googeling, and it works like a charm.
I wanted to share this here, so it can be easily found via Google and help other since I didn't find this all too quickly.
With this method, "window.clear(sf::color::transparent);" effectively works like you would expect it.
No setting shapes, no masking, no nothing.
Everything not overlayed with shapes / sprites whatever is fully transparent.
Everything you draw is there, even if it is semi transparent.
Even frigging steam overlay works as you'd might expect!

Graphics / Re: Render in one thread, load and manipulate Sprites in another, doesnt draw...
« on: July 15, 2013, 08:58:09 pm »
I hoped that you understand, but well it's no problem 
You're right... i dunno what i had in code before but now it works.. o.O
i should sleep more
sorry for wasting time...
edit: found my already solved problem... i also have top copy the textures somewhere in the renderring-class
seems like textures aren't completely stored in sprites...

Dang -.- ...
Had to set the same context in both threads and now it works like charm...
What you mean with "You don't need to use the window's context, you can use a new one."
If it automatically creates a new context, then it draws nothing, which was my problem.
Well, anyways you helped me out! Thank you!

« on: July 15, 2013, 08:18:04 pm »
Hi there,
I have seperate render-class of wich one function runs in a seperate sf::Thread to draw...
In another thread i want to load my textures and sprites, and manipulate them there
So far so good.
but if i want to load a texture, i have to activate the window in the thread i want to load the texture, wich would pause rendering.
so...
Something like this works:
and something like this gives me a blank screen and doesn't draw anything
i hope this is enough code to explain my problem...
basically something like

Something like this works:
// create the window
//...
//set up the renderclass
Render renderer;
renderer.setwindow.....
...
//load textures and set up sprites...
//copy them into render class
window.setActive(false);
sf::Thread renderthr(&Render::renderthread, &render); // create our renderer-thread
renderthr.launch(); //start the renderer
//...
//set up the renderclass
Render renderer;
renderer.setwindow.....
...
//load textures and set up sprites...
//copy them into render class
window.setActive(false);
sf::Thread renderthr(&Render::renderthread, &render); // create our renderer-thread
renderthr.launch(); //start the renderer
and something like this gives me a blank screen and doesn't draw anything
// create the window

window.setActive(false);

sf::Thread renderthr(&Render::renderthread, &render); // create our renderer-thread
renderthr.launch(); //start the renderer
//...
window.setActive(false);
//set up the renderclass
Render renderer;
renderer.setwindow.....
...
//load textures and set up sprites...
//copy them into render class
sf::Thread renderthr(&Render::renderthread, &render); // create our renderer-thread
renderthr.launch(); //start the renderer
i hope this is enough code to explain my problem...
basically something like
renderer.pause(true);
window.setactive(true);
//loadmytexture and create the sprite
//copy the sprity into the rendererclass
window.setactive(false);
renderer.pause(false);
would work but that is suboptimal...
window.setactive(true);
//loadmytexture and create the sprite
//copy the sprity into the rendererclass
window.setactive(false);
renderer.pause(false);

Graphics / Re: SFML+Windows Aero = EXTREMLY Low FPS/Use of Software Render?
« on: July 12, 2013, 10:49:34 am »
with or without sleep, doesnt matter btw: that first post is years old and i was using 1.6 back then...
other non-sfml opengl-apps run fine yeah!
its strange cuz even the hello-world code from the visual studio "guide" only runs at 8-9fps >.<
edit: seems it fixed itself after i got visual studio closed for a while...
will keep an eye on my system to see what causes this...
Edit: Seems like the Problem comes from my stone-aged TV-capture card and its semi-working drivers...

yeah exactly like that
nope
in win7 shutting of aero before running the application seemed to do the trick, making it working again for a 1 time usage... after that i had to reenable and disable aero again...
now in win8 i dont have this option of a workaround

haha yeah of course! everything works perfectly
if i restart the computer sfml works like a charm too, but i dont want to always restart my pc after i debugged 3-4 times...

Have to open up my old thread again, sorry...
Having the same Problem again... now, with windows 8, wich hasn't got aero... and a fresh new top-notch pc...
I dont know how to work around it now, or how i could fix it...
could this be because of an windows-service i shut off?
any halp would be greatly appreciated

I only tested it with an black/transparent image....
will try...
edit: your right... :/
edit2: OpenGLWidget conversion keeps the colours but flips the y of my image xD not that big deal, but kinda sucks
