详细描述

TumblerColumn represents a column within a tumbler, providing the interface to define the items and width of each column.

Tumbler {
    TumblerColumn {
        model: [1, 2, 3]
    }
    TumblerColumn {
        model: ["A", "B", "C"]
        visible: false
    }
}
					

You can create a custom appearance for a Tumbler by assigning a TumblerStyle .
