Re: [Ntw-devel] Timers

[Yua C. <ca...@gz...>]

I've modified the helloworld.c to add in a timer to test something out and 
realized that we don't have a clean way of closing out dialog windows...

I've created a callback function called ping as well as setting the window 
and timer variables to static:

static ntwWidget * pMainWnd; /* is the main window */
static ntwWidget * pMainTimer; /* is the timer */

void
ping (ntwWidget * user_data) {
  ntwWidget *dlg;
  ntwWidget *layout;
  ntwWidget *label;
  ntwWidget *button;
  ntwWidget *btnLabel;

  dlg = ntw_dialog_new(
    pMainWnd, /* parent window */
    100,            /* width */
     80,             /* height */
     TRUE,       /* Modality */
     "PING!!!!!"  /* Title */
   );

   layout = ntw_grid_new(3,2,FALSE);

   ntw_container_add(dlg,layout);

   label = ntw_label_new("A timer event has just occured.\n"
             "Please click the OK button");
   ntw_grid_add(
    layout,
    label,
    1,
    2,
    1,
    2,
    0,
    0,
    0,
    0
   );

  button = ntw_button_new();
  btnLabel = ntw_label_new("OK");

  ntw_container_add(button,btnLabel);

  ntw_grid_add(
    layout,
    button,
    1,
    2,
    2,
    3,
    0,
    0,
    0,
    0
  );

  ntw_add_callback(button, BUTTON_CLICKED, (func_ptr)&closePing,dlg,ASYNC);
  ntw_add_callback(dlg, DESTROY_EVENT, (func_ptr)&resetPing,NULL,ASYNC);
  ntw_add_callback(dlg, DELETE_EVENT,(func_ptr)&resetPing,NULL,ASYNC);

  ntw_widget_show(dlg);
}

now, the dialog will pop up and the timer will be reset when the dialog is 
closed using the close button ( 'X' in the upper-right ), but the closePing 
function:

void
closePing(ntwWidget * user_data) {
  ntw_widget_destroy(user_data); /* should be dlg */
}

seems to destroy the BUTTON, rather than the dialog even though dlg's 
pointer is the user data.  Any clues?

for completeness, here's resetPing:

void
resetPing() {
    ntw_timer_reset(pMainTimer);
}

and the timer is set up as:
...
pMainTimer = ntw_timer_add(10 /* seconds */,ASYNC);
ntw_timer_set_callback(pMainTimer, (func_ptr)&ping, timer);
