>Description:
First of all: I am using pkgsrg-current, with nightly updates. 
To compile CenterIM, I am using the default PKG_OPTIONS of the package.

Now to the problem:

CenterIM ignores keypresses, like "enter" when selecting a user from the userlist. It also ignores most other configured keys except for "g" (generic menu) and "s" (status menu), and the "arrow"-keys. (In those menus, "enter" does work, btw...)
At first, I got some garbage on the screen, too, but found out rather quickly that I have to add

INCOMPAT_CURSES+=       NetBSD 5.*_* NetBSD-5.*-*

to the Makefile to solve that problem. The Garbage is now gone, but the key-problem remains.

I have tried several things, from redefining keys through the config-files, running it inside and outside of screen, changing $TERM from xterm to vt100 etc., with no effect what so ever, the keys are still ignored no matter what I try.

Compile CenterIM from pkgsrc-current on NetBSD 5.0 (no matter whether some RC or RELEASE), arch i386, and start it with a valid IM-Account, e.g. ICQ.

 One further interesting thing: <enter> works on the user-tree to
 expand/collapse folders, but not to open chat-windows. For the other keys,
 the described behavior is valid.

 Hello,

 I just wanted to ask if there are any news about this problem, or anything
 I could contribute to help, since so far there seems to be no reaction to
 this PR other than an assignment...

 So far, CenterIM remains unusable and I still don't have clue why (else I
 would have attached a patch/solution :) )

 I have started to look at this.  When it starts up, the screen looks OK
 apart from any highlighted items are white on white (title, current
 selection).  Using the left arrow key will get me to a sub-menu plus box
 borders drawn in an odd place.  No other keys appear to do anything.

 This tends to imply that there is an application bug, as it will not work
 with either NetBSD curses nor ncurses.  I will look at the debugging output
 from our curses library and see what I can spot.

 Do other version of centerim (apart from the one in pkgsrc) work?

 Thanks,

 J

 Hi,

 For some reason, it looks like we lose keypad() mode, so that the arrow
 keys are treated as sequence of single keys instead of left, right, etc.
 I'm not quite sure why.  One oddity is that running with a high level of
 debugging for libcurses (compiled with make BEBUG_CURSES=1) makes the
 problem go away.

 The garbled screen looks like a refresh() related problem with multiple
 windows - I only see parts of the underlying main screen drawn, and not
 all of it.  This is probably due to a behaviour difference between our
 libcurses and ncurses.

 Thanks,

 J

 Yes.  I am doing all my tests with NetBSD's libcurses.

 The white on white behaviour is a centerim bug - it sets the highlighted
 items to be white foreground and default (i.e. whatever the terminal is set
 to) background colours.  As I use white background, I get white on white ;-)

 As I mentioned, this looks like a refresh() difference between NetBSD curses
 and ncurses.  I think it's to do with interactions between different curses
 windows (i.e. the background and the dialog box), where the specification is
 not clear on behaviour.

 Thanks for checking.  At least the versions of CenterIM are consistent.

 I have narrowed down the problem further.  For some reason, when we call
 getchar() from the curses library (src/lib/libcurses/getch.c:602), it
 returns -1 for the second character in an escape sequence (e.g. left arrow
 is the three characters <esc> O D when using an xterm).  This causes
 the parsing in "assembling a key sequence" state to abort.  (The other
 characters in the escape sequence are read after the extra -1.)  Also, as I
 mentioned previously, if I slow everything down by using a curses library
 with enough debug enabled, we read the key sequences for the arrow keys
 without a problem.

 I will see if I can spot why getchar() is returning -1.

 Thanks,

 J

 Ah ok. Well, in the end, it should not really matter. I haven't got it to
 work with base's curses, thus the INCOMPAT-line and ncurses.

 he he, ok. Well, if it's just that, I don't care: work-around "use
 different bg-color" is easily done :)

 If I can help, I'll do it :)
 And yes, it looks quite consistent.

 Now that you are mentioning terminal-types like xterm...I tried different
 $TERM values, e.g. vt100 and xterm, and the behavior of the keys never
 changed. I don't know if this information is helpful, but since I tried
 that, I thought it couldn't hurt being mentioned :)

 best regards

 Hmm, of course - this is EOF (from src/lib/libc/stdio/rget.c).

 >  I will see if I can spot why getchar() is returning -1.

 So, I looked at the CenterIM code, and discovered the getkey() function in
 kkconsui/src/conscommon.cc.  This is doing really horrible things to stdin.
 I'm amazed that it works anywhere.  Probably throwing most of that away will
 make things work.

 Thanks,

 J

 I had a similar problem (i.e. Enter key not working) on i386-netbsd.
 However, the same package (or was it CenterICQ ?) worked fine on
 alpha-netbsd.

 I don't think it's a keyboard issue, I believe that all actions that
 require a contact to be selected fail because the function returning
 the selected contact contains a bogus check:

 +	/* if((intptr_t) c < 100) c = 0; */

  	if(i) {
  	    switch(action = extk) {

 /**************** end of patch **************************/

 I looked in their source tree and it looks like this line
 was in there in a form or other since the initial import from
 CenterICQ.  To me, this looks like a guard against a bad memory
 reference that just happened to work whenever they were debugging
 a problem, and that was left in and is only seen in certain
 memory layouts (which is why it may have worked on alpha or
 other architectures or other OSes).  I can't imagine a valid
 reason to reject a contact if it lives in a certain part of the
 RAM...
