gui.lua's Issues

Add more widgets

If possible, I'd like to add the following widgets:

• BoxContainer
• GridContainer
• ScrollContainer
• TabContainer
• CheckBox
• ComboBox
• Image
• MenuBar
• ProgressBar
• Slider
• TextArea (unfinished)

Parameters not validated

Parameters to method calls are not checked for correct type, resulting in confusing situations as seen in #1. Adding calls to cc.expect in each API method validating the parameters would resolve this issue.

Also, because this module contains classes, it might be good to add an expectClass function that checks using Object:instanceof.

Missing documentation

Currently, little documentation is provided on the API beyond the demo.lua script. It would be helpful to document the behavior and parameters of each method, especially for complicated methods like LinearContainer:addChild.

Imposible to create gui

I wrote a gui, just to try if I can create an installer. But every time I got an error gui.lua:291: attempt to index local 'child' (a nil value)
I can not fix this, because I am not so good at lua. But your code demo.lua works. Help, please.
Here is the code:

local gui = require('gui')

local root = gui.Root:new()

local box = gui.LinearContainer:new(root,2,1,1)
--local box2 = gui.LinearContainer:new(root,1,0,0)

local lbl = gui.Label:new(root,"Hello!")
local btn1 = gui.Button:new(root,"Button 1")
local btn2 = gui.Button:new(root,"Button 2")
local btn3 = gui.Button:new(root,"Big Btn.")
--local field = gui.TextField:new(root,5,"TextField")
--local area = gui.ListBox:new(root,10,10,{})
--local sb = gui.ScrollBar:new(root,area)

--for i=1,64 do
--    table.insert(area.items,"Item "..tostring(i))
--end
btn1.enabled = false

function btn1:onPressed()
    lbl.text = "Pressed"
    root:onLayout() -- redraw entire screen
end
function btn2:onPressed()
    btn1.enabled = true
    btn1.dirty = true
end

--root:addChild(box2)

--box2:addChild(area,true,true,gui.LinearAlign.START)
--box2:addChild(sb,false,true,gui.LinearAlign.START)
--box2:addChild(box,false,true,gui.LinearAlign.START)

box:addChild(lbl,false,false,gui.LinearAlign.START)
box:addChild(btn1,false,false,gui.LinearAlign.START)
box:addChild(btn2,false,false,gui.LinearAlign.START)
box:addChild(field,false,true,gui.LinearAlign.START)
box:addChild(btn3,true,true,gui.LinearAlign.START)

root:mainLoop()

Theme engine

Label blank space not cleared

If the text in a Label becomes shorter, then residue is left behind

Documentation improvements

Documentation generator should search directories recursively.
It might also be good to move the script to a separate repository.
