The x and y coordinates of SortItemWidget's checkmark widgets were not updated, thus remained at their initial value 0. Consequently the intersectWith check in SortItemWidget:onTap always evaluated to false, resulting in taps on checkmarks in the sort widget not being recognized.

Widget that shows a checkmark (`✓`), an empty box (`□`)

or nothing of the same size.

local CheckMark = require("ui/widget/CheckMark")

|
|
table.insert(parent_widget, CheckMark:new{

|
checkable = false, -- shows nothing when false, defaults to true
|
|
checked = function() end, -- whether the box has a checkmark in it
|
|
})
|
|
UIManager:show(parent_widget)
|
|
|
|
]]
