Hi,

im currently trying to create my own GUI, but its hard and not really documented

So 2 questions:
1. How to instantiate a Filler? Those lined things, that are in the normal uis, where the ui can be dragged. Those agui:Filler objects.

2. Is it possible to change things in the "Production Statistics" and the "Trains-Overview" UI? I want to add additional information and dont find a way to manipulate those UIs.

No and no.

Hm, thats unfortunate. I have to make it differently
Thanks for the short and precise answer.

1) A standard frame will have a visual filler. But you can't use it to drag/drop the window because mod guis can't be moved.

ok, next question:

I want to have a max-height of around 80% of window-height. How to define a percentage of screen-heigth. Or even better, how to get the current window-height?

You have to divide display_resolution by display_scale btw, or else it'll be wrong if someone plays i.e. on a 4k screen with 200% scale.

Thanks for the help so far.
Next question:
Does a on_focus event exist? and how can i find out, if an element is focused?

No, at least not directly, and you can't. A lot of GUI related stuff (mouse position, cursor position in a text field, the focused element) is not part of the game state and therefore not readable. You can set the focused element using LuaGuiElement.focus().

Is it possible to change the design of a button? Or set the button to "active" state?
