I've finally got round to fiddling with curses, and I've got a test
program that works some of the time.
The immediate concern is the mouse. It works in an xterm window, and as
I read the docs it's supposed to work on a Linux VC with gpm active.
Well, it doesn't, at least for me.
I'm running RHL 7.3.
Here are the curses bits from my programs:
#include <curses.h>
#include <signal.h>
#ifdef NCURSES_MOUSE_VERSION
int ny = 0, nx = 0;
mmask_t MouseMask,newMouseMask = BUTTON1_RELEASED |
BUTTON1_PRESSED
| BUTTON1_CLICKED |
BUTTON1_DOUBLE_CLICKED | BUTTON1_TRIPLE_CLICKED;
#endif /* NCURSES_MOUSE_VERSION */
(void) initscr(); /* initialize the curses library */
#ifdef NCURSES_MOUSE_VERSION
MouseMask = mousemask(newMouseMask, (mmask_t *) NULL);
move(Line++,40);
printw("nn=%d, requested mm=%d\n", MouseMask, newMouseMask);
#endif /* NCURSES_MOUSE_VERSION */
keypad(stdscr, TRUE); /* enable keyboard mapping */
(void) nonl(); /* tell curses not to do NL->CR/NL on
output */
(void) cbreak(); /* take input chars one at a time, no
wait for \n */
(void) echo(); /* echo input - in color */
for (;;)
{
/* refresh, accept single keystroke of input */
int ch = getch();
if (ch == 4) break;
/* process the command keystroke */
switch (ch)
{
default:
break;
<snip>
#ifdef NCURSES_MOUSE_VERSION
case KEY_MOUSE:
{
MEVENT myevent;
addstr("\nClick!");
getmouse(&myevent);
nx = myevent.x;
ny = myevent.y;
printw("\nx=%d, y=%d",nx,ny);
ungetch('\n');
break;
}
#endif /* NCURSES_MOUSE_VERSION */
}
In an xterm window, I get reports like this:
nn=31, requested mm=31
has "Next Page" key
has "Prev Page" key
Click!
x=42, y=1
Click!
x=2, y=5
Click!
x=0, y=1
On a vc, no response to mouse-clicks.
I've checked this: http://en.tldp.org/HOWTO/NCURSES-Programming-HOWTO/
and see nothing to change.
Any hints?
