Narrow panels if terminal window is too wide

[ache]

If a terminal window is wider than 512 symbols, MC starts with panels only 80 symbols wide (40 each). If the window is resized, panels are resized correctly, however.

i try run terminal 630х200 - no problem.

Gentoo, AMD64, gnone-terminal 2.24.2-r1 or XFCE terminal 0.2.12. Problem still observed at 630х200 as well.

630х200 or 200x630?

Occurs at MC start ONLY. When window is resized to width >512, MC behaves correctly.

i set font 2pt and start terminal ~630х200
width: 630
height: 200

Confirmed with slang-2.1.3. This bug is S-Lang related, not NCurses.

Currently, during initalization S-Lang limits the scren size. Look at SLtt_get_screen_size():

   if ((r <= 0) || (r > SLTT_MAX_SCREEN_ROWS)) r = 24;
   if ((c <= 0) || (c > SLTT_MAX_SCREEN_COLS)) c = 80;
   SLtt_Screen_Rows = r;
   SLtt_Screen_Cols = c;

where r and c are the actual screen sizes. But

# define SLTT_MAX_SCREEN_COLS 512 
# define SLTT_MAX_SCREEN_ROWS 512 

[iNode]

# define SLTT_MAX_SCREEN_COLS 512 
# define SLTT_MAX_SCREEN_ROWS 512

So, it's resonable library "feature".
If you think this is bug, please write
bug report to s-lang developers.

Hi,
I am using a ultra-wide screen with 5120x1440 resolution and I am hit with this bug as well.

$  tput cols
632
$  tput lines
80

Is there possible to increase the SLTT_MAX_SCREEN_* variables in slang or completely remove the check?

Alternatively, to allow manual configuration of COLS and LINES in MC settings.

Thank you

SLTT_MAX_SCREEN_* are internal S-Lang constants. MC unable to change them at all. If you want you can patch S-Lang in your system.
A year ago these constants were removed. See #3980 for details.

Alternatively, to allow manual configuration of COLS and LINES in MC settings.

COLS and LINES are variables set by parent shell. Child process cannot change variables of parent one.

Nice, thanks

I know I just talked about manually settings the size of MC window. But I read through #3980 and I understand the slang must by updated instead of MC.
BTW reg to the comments in #3980 - would it be possible to use ncurses instead of slang or is it too much work to do?

Thanks
