anyone know where i can get some 'C' code for user interface primitives.
For example, source code to a text entry field.
The less dependancies the code has the better. I dont want to rely on
MFC, OpenGL etc, the puresr the C code the better.

Look at sourceforge.net... ;)

Best cross-platform one is likely:

What does it mean to be "Always On"?

too big, something that has the standard gui controls , and the code that calculates area in the controls
that trigger things, waits for keypresses etc,, but not so big that it is a complete library,, i need
the most primitive level code..

Take one of the above, strip out the pieces you don't need.

I'm highly doubtful you will find something that will fit your needs directly.  Any project on the net generally tries to fill being a complete GUI library -- though something like microwindows or picogui tries to fit on small footprint boxes and might thus be a better starting point.

To write really basic GUI pieces yourself wouldn't be that difficult -- static text, basic button, checkbox, radio group, scroll bar and list, maybe pop-up menu or drop-down menu, and editable text (the most difficult of them all!).  keyboard and mouse handling are pretty simple.  But, it's not hard, just would take some time to build it all from the ground up.  Would be a better learning experience.

Otherwise, try micro or pico and strip out what you don't need.

tell us what is it for, what's it's destined enviroment, cos i dont realy get the general idea...

if you're up to ground-zero level there is always a direct api of enviroment .. functional ( i mean based on functins rather than objects - what you want plain c ) winapi's great... i personaly prefer it to mfc

hi, sorry for being away from this:

What I am looking for is the low-level c logic for gui components..
for example snippets of code, that will calculate the width/height of the thumb tack of a scroll bar, depending on how many items
are in it. Snippets that will handling the mouse controling of a window being dragged etc.. Probably more geared towards
an embedded system in 'C'

apakian - have you looked at the other link farms, and the couple of specific further toolkits, I gave a month ago?

oh...

in that case there is one thing you may want to see...

it's the direct x ut (dxut) framework in it's newest edition ( included in dxsdk summer update 2004!!!) ... on of it's component is completly re-implemeted common controls like buttons, combobox, checkbox etc to work as an interactive elements of dx rendered context.... it has a _flat_ api, so you get the very idea flat as well :) regardles to some object oriented aspects of it's renderer it's worth looking at!!!

truly i hope it's enough cos i'm about to dig it as well ;)

just take a look at the customui example, and then simply dig the included dxut sources !

Oh SHEESH.  NOW you throw in a requirement like that?

The best of the systems I've already provided (pico and micro) are likely in the 100-300K range -- though, if you stripped it down of everything you didn't need, I'm sure you could get under 100K.

I'm done here.  You're looking for a custom system, or a commercial system someone has produced, and not something already open-source created... ;)
