No mouse support under "tmux" terminal multiplexer

[AlexJ]

In case of TERM="screen" or TERM="screen-256color"
no mouse support under terminal multiplexer "tmux".
Also Midnight Commander complain about: "Not an xterm or Linux console; the panels cannot be toggled" in case of Ctrl-o.

What have been done in attempt to allow to use MC under tmux:

1. attempt to run MC with option -x (force xterm), but it doesn't help.

2. Under version MC-4.7.2 there was possible simple trick that allow to run MC completely successfully under "tmux", - it's set environment variable TERM to "rxvt-256color" before calling MC with option -x, but it impossible with MC-4.7.5. Actually MC will start with mouse support in that case(TERM="rxvt-256color"), but coloring is broken, Ctrl-o switch to background but background is cleared.

I'll attach a few screen captures to show defect.

I talk with Nicolas(author of tmux) about this issue and he says MC should correctly support "screen" terminal without any tricks with TERM variable.

tmux has a lot of new features and has small memory footprint to compare with outdated "GNU screen" so if it possible it would be greatly appreciated if MC will be compatible with tmux that is "MUST have" for any admin.

Test was done on: FreeBSD-8.1 release
Terminal multiplexer: tmux-1.4
MC: 4.7.5
Remote access over PuTTY

Attempt to use Ctrl-o under TERM='screen-256color'

That's how MC looks after using F3(View)

No mouse support even under FreeBSD 8.2 RELEASE and Ubuntu 10.04 LTS using tmux or screen.

put follow lines into .profile

if [ $TERM = "screen" ]; then
    export TERM=xterm
fi
if [ -n "$TMUX" ]; then
    export COLORTERM=rxvt
fi

as a temporary solution...

Is this bug really fixed? I can replicate it with 4.8.5

What about 4.8.11? Or recent master?

I'm using xubuntu-13.10 with tmux-1.8 + mc-4.8.11 + xterm and mouse works. If you are experiencing problems with mouse under xterm+tmux, then try 'mc -x'.
