How can I automatically render list items when they go into frame?

[Agent-E11]

I have created a list of todo items like so:

todoList := widget.NewList(
    func() int {
        return len(todos)
    },
    func() fyne.CanvasObject {
        return widget.NewCheck("template", func(checked bool) {})
    },
    func(lii widget.ListItemID, co fyne.CanvasObject) {
        check := co.(*widget.Check)

        check.Text = todos[lii].Text
        check.Checked = todos[lii].Completed
    },
)

And then I set the content of the window

content := container.NewPadded(todoList)
w.SetContent(content)

But, all the todo items are like this

• template

Until I hover over them with my mouse (or tap them when in the mobile simulation).
How can I automatically render them when they are either in view, or the moment todoList is rendered?

you are forgetting to call check.Refresh() after you manipulate the state.

Thanks, that worked. Is that something that should be mentioned in the documentation?

So, instead of this (from documentation):

func(i widget.ListItemID, o fyne.CanvasObject) {
    o.(*widget.Label).SetText(data[i])
}

It would be this:

func(i widget.ListItemID, o fyne.CanvasObject) {
    o.(*widget.Label).SetText(data[i])
    o.Refresh()
}

Or is it left out on purpose?

It is left out on purpose because when you call a method it will refresh automatically for you.
When you directly edit state it needs to be told to refresh to get the update pushed to the renderer.
