Re: gEDA-user: GTKWave scroll in interactive mode (SOLVED)

[Abdous Mandous <abdous.mandous@xxxxxxxxx>]

Hi
I've made some changes in GTKWave source code to handle my problem. This
is what I've done, but I'm sure there are many better solutions:

1. If gcc complained about undeclared gzopen64; in src/helpers/tla2vcd.c
line 29 change 
	#include <zlib.h>
to
	#include "../libz/zlib.h"

2. Change kick_partial_vcd(void) in vcd_partial.c (line 2317):

///////////////////////////////////////////////////////////////////
void kick_partial_vcd(void)
{
#if !defined _MSC_VER && !defined __MINGW32__
GtkAdjustment *hadj;
TimeType ntinc;
if(GLOBALS->partial_vcd)
	{
	struct timeval tv;

	tv.tv_sec = 0; 
	tv.tv_usec = 1000000 / 100;
	select(0, NULL, NULL, NULL, &tv);

	while(*GLOBALS->consume_ptr_vcd_partial_c_1)
		{
		Trptr t;
	
		vcd_parse();
	

GLOBALS->min_time=GLOBALS->start_time_vcd_partial_c_2*GLOBALS->time_scale;

GLOBALS->max_time=GLOBALS->end_time_vcd_partial_c_2*GLOBALS->time_scale;
	
		GLOBALS->tims.last=GLOBALS->max_time;
		GLOBALS->tims.end=GLOBALS->tims.last;             /* until the
configure_event of wavearea */
	
		if(!GLOBALS->timeset_vcd_partial_c_1)
			{

GLOBALS->tims.first=GLOBALS->tims.start=GLOBALS->tims.laststart=GLOBALS->min_time;
			GLOBALS->timeset_vcd_partial_c_1 = 1;
			}
	
		update_endcap_times_for_partial_vcd();
		update_maxmarker_labels();
	
		t = GLOBALS->traces.first; while(t) { regen_trace_mark(t); t =
t->t_next; }
		t = GLOBALS->traces.buffer; while(t) { regen_trace_mark(t); t =
t->t_next; }

		t = GLOBALS->traces.first; while(t) { regen_trace_sweep(t); t =
t->t_next; }
		t = GLOBALS->traces.buffer; while(t) { regen_trace_sweep(t); t =
t->t_next; }
	
	        signalarea_configure_event(GLOBALS->signalarea, NULL);
	        wavearea_configure_event(GLOBALS->wavearea, NULL);
	     
		ntinc=(TimeType)(((gdouble)GLOBALS->wavewidth)*GLOBALS->nspx);
		GLOBALS->tims.timecache=GLOBALS->tims.last-ntinc+1;
			if(GLOBALS->tims.timecache<GLOBALS->tims.first)
GLOBALS->tims.timecache=GLOBALS->tims.first;

		hadj=GTK_ADJUSTMENT(GLOBALS->wave_hslider);
		hadj->value=GLOBALS->tims.timecache;
		time_update();
	     
	     
		gtkwave_gtk_main_iteration();
		}
	}

#endif

gtkwave_gtk_main_iteration();
}
///////////////////////////////////////////////////////////////////
In fact I've added "Zoom To End" button's code from service_zoom_right
function (in zoombuttons.c line 57) to kick_partial_vcd().

I've written a very simple program that makes randome vcd file. You can
use it in this way (I assume you are in ~/gtkwave-3.1.9/src, if not
change the paths):
	 ./randomvcd | ./helpers/shmidcat | ./gtkwave -I -v

randomvcd.c and my vcd_partial.c are attached in a compressed file.
I hope this will be useful..

Abd. Man
