I have provided a TimeBar with a skin. For the option skin_handle I wanted to use a horizontal scale. The TimeBar is intended to fill. Unfortunately, it does not work. Does anyone have any idea?
HBTimeBar1 = 10TimeBar1(minheight=6,maxheight=6,minwidth=80,maxwidth=80,skin=progress_bar_base.png::,handle_skin=progress_bar.png::hs:normal_prelight_active)

The next problem is the button play. This is also skinned. Actually, he should for the different states have different appearance. But that does not work either, unfortunately.
Play0(skin=play_pause_text.png:::normal_prelight_active:Play_Paused)
