QtRuby - Error


#1

Hello,
I new in the ruby world.
Sorry my english, i’m argentino and speak spanish.

My question is about QtRuby. Where can tutorials, Faq, Qt’s Classes?.
Qt4 work with ruby or only Qt3?
I’ design form with Qt4-designer and:

rbuic mainWindow.ui > mainWindow.rb

##################################################################
ggerman@comandante:~/Qt4/example$ cat mainWindow.rb

Form implementation generated from reading ui file ‘mainWindow.ui’

require ‘Qt’
class MainWindow < Qt::MainWindow
def initialize(parent = nil, name = nil, fl = WType_TopLevel)
super
statusBar()
setCentralWidget(Qt::Widget.new(self, “qt_central_widget”))
@Widget = Qt::Widget.new(centralWidget(), “Widget”)
@MenuBar.setProperty( “geometry”,
Qt::Variant.new(Qt::Rect.new(0, 0,
409, 29) ) )
@StatusBar = Qt::StatusBar.new(centralWidget(), “StatusBar”)
languageChange()
resize( Qt::Size.new(409, 580).expandedTo(minimumSizeHint()) )
clearWState( WState_Polished )
end
#
# Sets the strings of the subwidgets using the current
# language.

def languageChange()
setProperty(“windowTitle”,
Qt::Variant.new(trUtf8(“MainWindow”)))
end
protected :languageChange
end
if $0 == FILE
a = Qt::Application.new(ARGV)
w = MainWindow.new
a.mainWidget = w
w.show
a.exec
end

rbuic mainWindow.ui > mainWindow.rb

You’re mixing QtRuby versions here. The rbuic you are using is for
QtRuby for Qt3.
You probably need to use rbuic4 (that’s what it’s called on my system).

Sorry my stupid question.
