nanogui: Thread: Stupid Question

Hi,

I'm a kind a newbee here in the list. But I was watching the
nanox/microwindows development for a quiet same time.
I'm would like to use nanox for my own build platform with a graphical
interface. But I have already a very fast line drawing
routing ( mostly written in assembler). In nanox there is a general
routing for lines as well. Now some hardware can do the
line business in hardware very fast as well. Is it possible to extend
the screendevice structure with line routine and use this one
if exist instant of the C routine ? May be I didn't  see something, but
I guess in general it should be possible.
The Code is even already there to do something like this
("src/engine/devdraw.c").

Is it possible to extend
: the screendevice structure with line routine and use this one
: if exist instant of the C routine ? May be I didn't  see something, but
: I guess in general it should be possible.

Currently, there are screen device entry points for horizontal
and vertical line drawing that can be overridden and replaced.
We don't currently have the arbitrary (bresenham) line drawing
routine in the screen driver since for size reasons the clipping is
checked upstairs...

Regards,

Greg

Roman,

1. Sorry for delay.
2. The most stupid question is not asked one.
3. You should read closely microwindows-architecture.html file.
4. The only you have to do for porting is to change or modify three
files - drivers: for screen, for mouse, for keyboards. That's ALL.
How to do it ? Look at microwindows/contrib. You can find there
port for MSDOS using DJGPP, BORLAND C, PACIFIC C.
5. You should begin with program test.

Hello,

    I'm just begining to use nano-x/microwin and I've some pretty stupid questions,

    Which is the most stable configuration? and how can i get my framebuffer to work, I can only get 640x480x256 and I need (4 compatibility reasons) to get 640x480x 16 colours

Thanks 4 all,

Vicente Werner

Read the framebuffer HOWTO, it's url is listed in microwin/src/INSTALL.
If you run 2.2.14, you can build a 640x480x16 framebuffer, and Microwindows
will run on it.
