lwtk - Lua Widget Toolkit

This toolkit provides a foundation for building cross platform GUI widgets in pure Lua on top of LPugl or within the LÖVE 2D game engine. For LPugl only the cairo drawing backend is supported. Further Backend abstraction and support for other backends could be possible in the future.

This project is work in progress. First aim is to provide a basic infrastructure for creating and customizing widgets. Second aim is to implement a reasonable set of standard widgets. So far only very simple standard widgets are provided, e.g. lwtk.TextInput and lwtk.PushButton.

Supported platforms:

• Linux (X11)
• Windows
• Mac OS X
• LÖVE 2D game engine

First Example

• The first example demonstrates a simple "Hello World" dialog. The appearance of the widgets is configured in lwtk.DefaultStyle. The key bindings are configured in lwtk.DefaultKeyBinding.

  

  local lwtk = require("lwtk")
  
  local Application    = lwtk.Application
  local Column         = lwtk.Column
  local Row            = lwtk.Row
  local PushButton     = lwtk.PushButton
  local TitleText      = lwtk.TitleText
  local Space          = lwtk.Space
  
  local app = Application("example")
  
  local function quit()
      app:close()
  end
  
  local win = app:newWindow {
      title = "example",
      Column {
          TitleText  { text = "Hello World!", style = { textSize = 35 } },
          Row {
              Space {},
              PushButton { text = "&OK", onClicked = quit },
              Space {}
          }
      },
  }
  win:show()
  app:runEventLoop()
