Is there any way to make it as shiny and smooth as it was with point sprites? I use this call to draw the quads: gl.glDrawElements(GL10.GL_TRIANGLES, vertices*2, GL10.GL_UNSIGNED_SHORT,indiceBuffer); I don't think that I can use glDrawArrays,because that is for TriangleStripArrays. I have 1200 particles, which makes it 4800 vertices in the array for the quads. The positions are morphed for each repaint. Maybe that is what is making it slow,but it was fast with point sprites. Each star particle consists of 2 quads. The star particle in the middle is smaller quad. The transparent blueish blur around that particle is another quad. These are drawn with 2 arrays. I draw the most opaque array first (the star particle in the middle) and then the more transparent array later. This approach worked very well with point sprites and size attenuation, but maybe this doesn't work with texture mapped quads. Maye there are simply too much quads for the system to take care off, which messes up the Depth Testing and the z buffer. Maybe this is the reason that the transparency is not working like it should, which causes the visible black square quads?

Quite possibly, you're right... So HTC hasn't implemented the things that they say in the specification, but why not? Who knows? You could contact their support, but even if they provide a plausible answer (and that's a big if), it's not going to magically fix all the HTC devices out there... Thanks for the idea, do you mean like this? Scale to small size if the sprite is far away. Scale to medium size if the sprite is medium distance. Scale to big size if the sprite is close. More or less - you are currently doing continuous range scaling of your sprites (I presume). If you replace them with texture mapped quads, you could always use the same image, or pick one of the ones predefined at various scale factors, to improve the image quality and performance. Sort of like mip-mapping. But that's not the core idea - the main thing is to replace attenuated points with texture mapped quads. That could work for other animations, but it would be very slow for my star cluster animations. There are hundreds of stars in each cluster. As it is now, I draw each star cluster in one single glDrawArrays call. That makes it fast. Hundreds doesn't sound too bad - at those poly counts, it's the fill rate (overdraw) that can kill performance. But since sprites are typically small, it probably won't be an issue. Wouldn't I have to make one glDrawArrays call for each one of the stars if I had to scale them in different sizes? That would mean hundreds of glDrawArrays calls instead of one. Not the

You have to build your reg-ex using character classes designed to deal

And, with a flag to enable or disable the path-separator char (fun read:http://blogs.msdn.com/b/oldnewthing/archive/2005/10/14/481044.aspx ) On the other hand your suggestion seems like a good (the only?) option for an hardware keyboard. I'll go hunting for an 'official' list of locale-specific path separators... Maybe it's just Yen, Won and slashes-backslashes... best -- Mathieu On Aug 24, 6:39 pm, Daniel Drozdzewski daniel.drozdzew...@gmail.com wrote: On 24 August 2011 17:05,bdkmathieu.b...@gmail.com wrote: Hi I'm showing the user a Save as... dialog to save files, and I'd like to disable a set of 'reserved characters' into a related EditText field.

In the listener you capture the text change event and filter through only allowed characters. -- Daniel Drozdzewski -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Disabling a set of 'reserved characters' from user Input?
