| Issue |
Is it possible for an application to dynamically change the small SIcon that shows up at the bottom of screen while it is running?
|
| Solution |
Yes, it is possible. You need to set the Pt_ARG_LABEL_DATA resource of the SIcon widget.
For example this is how the dialer blinks its lights on the icom:
x09ApDBase_t *icons_db;
x09icons_db = ApOpenDBase(ABM_icons);
/*'"icons" is a picture module containing PtLabel widgets named CIcon1, CIcon2, ...*/
x09char wgt[8];
x09PhImage_t *image;
x09PtArg_t arg;
x09sprintf( wgt, "CIcon%d", index);
x09image = ApGetImageRes(icons_db, wgt);
x09PtSetArg(&arg, Pt_ARG_LABEL_DATA, image, sizeof(*image));
x09PtSetResources(ABW_SIcon, 1, &arg);
