I'm building a preferences menu. Preferences can take multiple forms, such as the simple bool for which I am using a checkbox/button. I use a table to hold preferences, along with things like their default value, range, etc. These will be displayed in a tree_view, with the node type depending on new_prefs.type (e.g. bool == button).
Now for the float, I'd like to use a slider, and that slider's minimum and maximum values and step size aren't known when I create the node definition, and it appears they cannot be modified on the fly. My guess is that they are fixed, and I have to define them when I define(/instantiate/initialize/?) the widget.
If I am correct, then my question is how do I create/define/whatever a widget in a tree_view "at runtime"?
My first thought was gui.add_widget_definition(), then something using add_item_of_type, but these ideas aren't really going anywhere for me. If you're wondering what in the world made me think those might be the answer, they're the only things I know that create stuff dynamically.
I hope this make some sort of sense. At least, what I'm trying to do.
I could just use a text_box of course, but I've built myself a puzzle I don't know how to solve with the slider idea (and it just seems like a nice way of constraining input to a "valid" range).
This was my original attempt:
Code:
table.insert(new_prefs,{ id = "northfrost_animation", default = true , type = "bool", value = true, description = _"Display animation for northfrost aura"}) table.insert(new_prefs,{ id = "ai_aggression", default = 1, menu = "ai", type = "float", value = 1, min=-10, max = 2, step = 0.1, description = _"aggression"})Now for the float, I'd like to use a slider, and that slider's minimum and maximum values and step size aren't known when I create the node definition, and it appears they cannot be modified on the fly. My guess is that they are fixed, and I have to define them when I define(/instantiate/initialize/?) the widget.
