nanogui: Thread: [Nano-X] 0.88pre10 + fltk-nanox-pre6

Dear All,

	On my system, the mouse cursor doesn't move and keyboard input
	doesn't have any response.
	It seems something goes wrong with the event delivering mechanism.

	The following is a dirty fix to the problem:

	Originally, in Fl_x.cxx, Row 209:
	--------------------------------
//      GrCheckNextEvent(&ev);
//      if(ev.type!=0)
        if(GrPeekEvent(&ev))
        {
                do_queued_events();
                return time;
        }

	Dirty fix:
	---------
        GrCheckNextEvent(&ev);
        if(ev.type!=GR_EVENT_TYPE_NONE)
//      if(GrPeekEvent(&ev)) 
        {
                fl_handle(ev);
                do_queued_events(); 
                return time;
        }

	Hope this helps.

Sincerely,
Murphy

Which demo are you running?  What is the microwindows screen
driver that you're using?  Which mouse driver?  I haven't seen this problem.

Greg

	I've encoutnered this problem in all the demos in flnx/test.

	I tried both framebuffer with gpm and X11 driver.

	PS. The demo programs of Nano-X are working well.

Sincerely,
Murphy

Dear Greg,

	Another problem is about the tty keyboard driver.

	When I run flnx test programs under X11, 'alt'+'F' and
	arrow keys work fine.

	But under framebuffer with tty keyboard driver,
	these keys does not work, and will terminate demo programs.

	Is there any environmental variables I need to set?
	( My Linux version is 2.3.99pre9. )

Sincerely,
Murphy

: 
: But under framebuffer with tty keyboard driver,

The problem is that we don't yet parse function keys
or alt-combinations and convert them into single integers.
So when you press LEFT ARROW, an ESC [ A is
sent (three characters) from the kbd driver to the lowest level
Microwindows tty driver.  The driver just thinks the user
typed ESCAPE, [, A.  The first escape will cause Microwindows
to exit unless run with the -e option.

I've just started working to fix this problem.  Expect
changes in the 0.89 release.

Greg

Hi,

Flnx/DJGPP has the same problem - I can see all demos, but mouse didn't move.

Regards,

Victor.

Does the attached fix from Murphy solve your problem, Victor?

If so, I will change the FLTK nano-X port.

Greg

Murphy, thanks !

My mouse is very glad. It can move :-)

I have compiled flnx / djgpp with your fix.

Victor.
