GUI Library for ComputerCraft:Tweaked

This is a GUI library loosely inspired by PySimpleGUI intended for CC:Tweaked, but should function on just about any version of CC.

Quickstart

Add the ccsg/ directory to your CC computer, include gui.lua, widget.lua, and any widget/extension files you'd like. To create a gui program first include what you require.

local gui = require("ccsg.gui") -- required
local text = require("ccsg.text")
local button = require("ccsg.button")

Then create your window table/object

local win = gui.new({
  text.new{{1,2}, {14,1}, label="Hello World!"}, -- position and size can be passed in through 1 and 2 indicies
  quit = button.new{pos={1,3}, size={14,1}, label="Quit!"}, -- or explicitly
  -- and the quit button is accessed through a key
{autofit=true})

The first argument is a table of widgets, I set up a text and a button widget. The second argument is optional, it's a list of initial starting parameters for the gui, in this case I've enabled autofit, this means that the window I created will be centered in the terminal (this expects your top-left corner of your gui to be at 1,1). There is a devMode parameter, which when true allows dragging and resizing widgets with left/right click and will print out information about the selected widget on a middle click. More information can be found in the docs.

And finally set up your event loop.

while true do
    local events, values, e = win:read()
    if events == "quit" then
        -- The "Quit!" button was pressed.
        term.clear()
        term.setCursorPos(1,1)
        break
    end
end

In this snippet events contains either a number, string or nil, if it contains anything other than nil then that is the index of the widget which was interracted with. values contains a table of the values of each widget at the moment win:read returns (indexed by index of widget). e contains a table of the {os.pullEvent()} call.

You can access your widgets through win.widgets (or whatever you name your win object).

This example is located in helloworld.lua.

Theming

You can change the theme of the gui by changing the key theme in your gui object. There are a few to pick from in gui.lua, or you can pass in your own.
