Rainbow phase 1 finished [message #33320]

My list of issues to be implemented for Framebuffer (as first proof-of-concept rainbow backend for U++) is now empty (except for some possible optimizations), so I consider this phase complete.

Hereby is win32 example:

http://code.google.com/p/upp-mirror/downloads/detail?name=UW ord.zip&can=2&q=#makechanges

I would like to ask U++ community for testing this Win32 executable (just to explain, obviously running framebuffer backend in Win32 window does not make much sense except for development purposes, but it has to run anyway).

Everything should work, including clipboard and drag and drop - obviously they only work inside "framebuffer environment".

Next steps now should be

- macosx
- android
- maybe "gtk backend" - one which is more tightly bound to gtk
- ditto for QT

Volunteers needed Smile

Great news! Smile

I tested the executable in Wine, and it works like a charm. Just the cursor looks a bit weird, should it really have that yellowish tip? index.php?t=getfile&id=3394&private=0

You forgot to add the Wayland display server to your list Wink

The drawing part will be probably quite similar to framebuffer, so it shouldn't be very difficult.

I already tried to compile wayland and get it running on my Arch Linux with mixed results - the server runs, the clients don't Confused

But as soon as I get it to work, I promise to volunteer Wink

Best regards,
Honza

Well, it is just so that I could tell that I am now displaying FB cursor (painting in FB), not Win32 one Wink

Yes, right. I am all for replacing X11, OTOH it does not seem like pressing matter right now. Besides, if we get "tighter" gtk, we get wayland for free.

Strange. It doesn't work for me. Ubuntu 10.04, Compiled under wine using MSVC 9.

EDITED: Sorry, my bad. It works fine in Wine.

Hi Mirek,

Appears to run fine under Windows 7/x64. On Windows XP Pro 32-bit, however, there are two cursors visible: The one with yellow interior below and the one with white interior on top. The white is obviously from XP and reacts faster.

Best regards,

Tom

Well, WinFb part is just a quick hack with no practical use. I guess I will ignore this now... Wink

Thanks anyway.

Tried to test framebuffer on linux (Ubuntu 11.04) and get the following error:

Quote:

Error reading fixed information.

in the /LinuxFB/Win.cpp (254) code:

	if (ioctl(fbfd, FBIOGET_VSCREENINFO, &vinfo)) {
		fprintf(stderr, "Error reading variable information.\n");
		exit(-3);
	}

Tried to run the compiled example with sudo command and everithink work fine.

Any hint are welcome!

well, maybe i should have added some comments on LinuxFb somewhere.

ofcorse, the executable is to be started from commandline of a (virtual) terminal. most linux distros do only allow for user mode to open it's tty. /dev/fb0 and /dev/input/mice are root only. so reading/writing them directly needs you to be root.

besides that, everything should work fine. what'd be great is to test copy&paste and DND, recently added by mirek. i currently dont have time to do so. could you?
