I have come across a trivial problem while developing an interface to drive our LiDAR (think of it as a telescope with a 3000W laser pointer attached). When I tell the telescopic mount to go to a particular elevation or azimuth via an EditDoubleNotNull field, it calls the callback function for every character typed in instead after a <CR> or moving the mousse out of the focus area. What is the easiest way to force the evaluation after a <CR>?
Follows is the prototype code:
void telescope_ctl::btn_move_el_ctl()
{El = (double)~jog.jog_pos_el;}
telescope_ctl::telescope_ctl()
{
...
jog.jog_pos_el <<= THISBACK(btn_move_el_ctl);
...
}
Thanks,
