[GUI] spinner and repeating button

[white_haired_uncle]

I'm trying to create an example of using a spinner, since I can't find one. I had a hard time figuring out how to get the value out of it, and while it works, I'm not really happy what I did. So, what is the right way to do this? It seems like there should be a spinner.text, not spinner._text.text.

Also, I want to change the speed of the repeating buttons, both here and for any repeating button. Docs say 'every x' ms, but I don't see where to set x.

Code: Select all

function wesnoth.wml_actions.slider_and_textbox()
        local dialogDefinition = {
                wml.tag.tooltip { id = "tooltip_large" },
                wml.tag.helptip { id = "helptip_large" },
                wml.tag.grid {
                        wml.tag.row {
                                wml.tag.column {
                                        wml.tag.label { label = _"How much gold will you pay for this old rusty sword?" }
                                }
                        },
                        wml.tag.row {

The spinner is a very new widget, so it's possible that some essential parts of interacting with it in Lua just haven't been implemented yet. I don't know any details about it.
