Hi all,
I have a question regarding wxSlider. I'm developing a wxwidget python
interface for a robotic hand. The sliders send the target values to the
joints.
I'd like to display the current position of the joint on the slider. I
wanted to use wxSlider.SetTick(myposition) but I couldn't get SetTick to
display anything.
Anyone has an idea ? I attached a dummy code to the message to illustrate.
Cheers,
Ugo
