  show_underline_ = visible;
  SchedulePaint();
}
void SubmenuButton::SetUnderlineColor(SkColor color) {
  underline_color_ = color;
}
void SubmenuButton::GetAccessibleNodeData(ui::AXNodeData* node_data) {
  node_data->SetName(GetAccessibleName());
  node_data->role = ax::mojom::Role::kPopUpButton;
}
void SubmenuButton::PaintButtonContents(gfx::Canvas* canvas) {
  views::MenuButton::PaintButtonContents(canvas);
  if (show_underline_ && (underline_start_ != underline_end_)) {
    float padding = (width() - text_width_) / 2;
    float underline_height = (height() + text_height_) / 2 - 2;
    canvas->DrawSharpLine(
        gfx::PointF(underline_start_ + padding, underline_height),
        gfx::PointF(underline_end_ + padding, underline_height),
        underline_color_);
