Re: Penlight - Calling the constructor of a parent class

[Luciano de Souza <luchyanus@...>]

I don't know if I understood what you mean. The Penlight manual 
recommends "self:super(title". With the following code, I get an error 
since the global "super" does not exist:

require('iuplua')
require('iupluacontrols')

class = require('pl.class')

class.control(class.properties)

function control:bind(control, event, callback)
control[event] = function (control)
callback()
end
end

class.window(control)

function window:_init(title)
self.dialog = iup.dialog{title = title, size = 'THRIDxHALF', gap = 5}
self._container = iup.vbox{}
end

function window:show()
self.dialog:showxy(iup.CENTER, iup.CENTER)
end

function window:run()
iup.MainLoop()
end

function window:set_container(data)
local hbox = iup.hbox{border = 'NO'}

for _, v in ipairs(data) do
if type(v) == 'table' then
for _, c in ipairs(v) do
iup.Append(hbox, c)
iup.Append(self._container, hbox)
end
else
iup.Append(hbox, v)
iup.Append(self._container, hbox)
end
end
iup.Append(self.dialog, self._container)
end

class.custom(window)

function custom:_init(title)
super(self, '_init')
end

custom = custom('Test')
custom:show()
custom:run()
