Hello, I'm fairly new to FLTK but I am having some trouble getting a
Fl_Valuator to update from a callback. I currently have the following callback
on a button:
{
boost::thread t(boost::bind(&MotorControl::Sweep, motor_control));
}
This should call the MotorControl::Sweep method in a separate thread. Within
this method I issue the value(int) method on a few Fl_Valuators to change their
values. There is also a boost sleep command between these method calls.
My issue is if I do not move the mouse, the Fl_Valuators (which are horizontal
sliders) do not update their positions. When I do move the mouse, the sliders
instantly jump to their correct values.
How can I get the "Fl_Value_Slider"s to update correctly without me moving the
mouse?
Thank you!
