vg4->dialog->nw_server()

Open a canvas-dialog for starting or stopping network-server locally.

SYNTAX

VG_BOOL vg4->dialog->nw_server(const char *cvasdir, const struct VG_Position *posdst, struct VG_Hash *hvar)

FUNCTION PARAMETERS

cvasdir	Directory to load canvasses from, or NULL = use system-canvasses
posdst	Canvas-position on window, or NULL = centered
hvar	Hash with variable-values (see vg4->canvas->load())

RETURN VALUE

Returns boolean: - VG_TRUE: OK - VG_FALSE: Got exit-request

DESCRIPTION

Open a canvas-dialog for starting or stopping network-server locally. This function uses following canvas-file (installed below share/vgagames4/canvas/) - nw.server.cvas: Top-canvas The parameter hvar should contain following variables - key: server:info-ison-local value: text if server is running, e.g. Server running locally - key: server:info-ison-remote value: text if server is running, e.g. Server running in LAN - key: server:info-isoff value: text if server is not running, e.g. Server stopped - key: server:buttontxt-ison value: button-text if server is running, e.g. Stop - key: server:buttontxt-isoff value: button-text if server is not running, e.g. Start If own canvas-files shall be used instead of the system-canvas-files, they must lay in cvasdir or cvasdir/network/ and have the same names as the system-canvas-files: - nw.server.cvas - uses canvas-items: - [CV-TEXT] with name info: text for server-state - [CV-BUTTON] with name button: starting or stopping the server locally - [CV-BUTTON] as a cancel-button - uses variables: - key: buttontxt value: button-text

EXAMPLE

  struct VG_Hash *hvar;

  hvar = vg4->hash->create();

  /* set variables */
  vg4->hash->setstr(hvar, "server:info-ison-local", "Server running locally");
  vg4->hash->setstr(hvar, "server:info-ison-remote", "Server running in LAN");
  vg4->hash->setstr(hvar, "server:info-isoff", "Server stopped");
  vg4->hash->setstr(hvar, "server:buttontxt-ison", "Stop");
  vg4->hash->setstr(hvar, "server:buttontxt-isoff", "Start");

  /* execute dialog */
  if (!vg4->dialog->nw_server(NULL, NULL, hvar)) {
    /* exit request */
    VG_dest();
    exit(0);
  }

  vg4->hash->destroy(hvar);
