Hi LVGL forum,

I was trying this example for LVGL-8, its working fine :–
https://docs.lvgl.io/8.0/widgets/core/roller.html#add-fade-mask-to-roller

Some questions I have & need your help.

  • How to change width & height of this roller ?
  • How to change Width height of each ROW of the column ?

We can add some, some symbols to roller in this way :–
lv_roller_set_options(roller1,
LV_SYMBOL_AUDIO " 1\n"
LV_SYMBOL_VIDEO " 2\n"
LV_SYMBOL_LIST " 3\n"
LV_SYMBOL_GPS " 4\n"
“12”,
LV_ROLLER_MODE_NORMAL);

  • How can i add the custom image to roller ?

Please suggest

Dinesh
