You can do interesting things with ClanLib 0.9 GUI

See attached picture.

It is showing that you can interact with a GUI window, even after rotation.

Very, very cool. :)

It's weird, but this program, and only this program causes my graphics card to squeal. After doing some research I suppose some people get this squealing issue with GTX 260 / 280 cards. But they tend to report it happening everytime they play games.

Currently, only this little GUI demo does it to me! How very odd I thought. I snoped around in the code and I couldn't see why..

Though when rendering at 4000 frames per second, maybe the card is just screaming for mercy? Haha.

That's strange.

Try changing flip(0) to flip(1)

This should lock the framerate to 100fps, or whatever your monitor refresh rate is

Hopefully it'll stop squealing

(I've never heard of squealing graphic cards until today!)

My 8800 GTX starts making a sound too when I get these extremely high framerates. I just smile when I hear this sound because it means its FAST FAST FAST :-)

Well, I guess it's just the g92 based stuff (8800GT and up), and their derivatives. Something to do with Nvidia skimping on hardware, so power can be heard through the copper coils. Interesting read here:

Either way, it's the first time I ever experienced it myself, but a little research shows while it's not frequent, it isn't unheard of.

It is related to the insanely high frame rates though. Throttling it back with flip(1) cured the issue. Would always explain why it doesn't seem to happen in 3d games and whatnot... I don't often run at those speeds...

The only game I've heard the squealing is in Crysis when it displays the logos in the beginning. So apparently they keep displaying the logo as fast as they can in a loop for X seconds with no vsync. :)

This 3D GUI example has been deleted ...

... instead the GUI example demonstrates how to use the GUI in a 3d environment (ClanLib-0.9/Examples/GUI)

OMG! That is the coolest thing I've seen in a long time :) The screenshot doesn't really do it justice - you have to try it out for real to see how cool it is. Really shows the power of ClanGUI :)

Very nice job, Rombust!
