'pause mouse' problems gnuplot (gnuplot, wgnuplot ) for windows (was Re: pause mouse ....)

[Tatsuro M. <tma...@ya...>]

Hello

I have found that pause mouse does not work in  wxt terminal  on wgnuplot.
This is probably because the description in command.c.

****************************
#if defined(_Windows) && !defined(WGP_CONSOLE)
    if (paused_for_mouse && !graphwin.hWndGraph) {
	if (interactive) { /* cannot wait for Enter in a non-interactive session without the graph window */
	    char tmp[512];
	    if (buf) fprintf(stderr,"%s\n", buf);
	    fgets(tmp, 512, stdin); /* graphical window not yet initialized, wait for any key here */
	}
    } else { /* pausing via graphical windows */
	int tmp = paused_for_mouse;
	if (buf && paused_for_mouse) fprintf(stderr,"%s\n", buf);
	if (!Pause(buf)) {
	    if (!tmp) {
		bail_to_command_line();
	    } else {
		if (!graphwin.hWndGraph) 
		    bail_to_command_line();
	    }
	}
    }
***************************

In the above description, only for the windows terminal is considered.
Now, we can have two interactive terminals, window and wxt.

So that pause mouse treatment for window terminal should not be described here but in win.trm.


At least windows, the description for 'pause mouse' should be modified.
Therefore the patch I posted for gnuplot.exe should also be modified.

On weekdays I will not have enough time to consider this issue.

Please forgive me.

PS. I do not know for the case of Macintosh and OS2.
