hello:show()

app.exec()

2. Show www.zaccn.com:

require'qtcore'
require'qtgui'
require'qtwebkit'

app = QApplication.new(0,{})
app.__gc = app.delete -- take ownership of object

webView = QWebView.new()
webView:setUrl(QUrl.new(QString.new('http://www.zaccn.com')))

app.exec()

3. Unicode

require'qtcore'

umlaut = QString.new('Ö')
utf8 = umlaut:toUtf8()
print(string.byte(utf8, 1, #utf8))

4. Evaluate JavaScript

require'qtcore'
require'qtscript'

engine = QScriptEngine.new()
result = engine:evaluate(QString.new('p=function(){print(/"Hello World/");}; p();'))
