TreeModelFilterModifyFunc
typealias TreeModelFilterModifyFunc = (model: TreeModel, iter: TreeIter, <Error class: unknown class>, <Error class: unknown class>) -> Unit(source)
A function which calculates display values from raw values in the model. It must fill @value with the display value for the column @column in the row indicated by @iter.
Since this function is called for each data access, it’s not a particularly efficient operation.
