Installer with Language Selection

[xyz-Mann]

Hello Guys,

I have some Problems with the QT Installer

I already done all tutorials but i am a real newbie

What i need:

• an installer with a language Selection as first page
• adding a second (save) path in TargetDirectory

What i have:

• an installscript.js (package root)
• an ControlScript.js (path in config.xml)

What i tried:

• function Controller()
  {
  QMessageBox.information("DEBUG", "DEBUG", "DEBUG", QMessageBox.Ok);
  installer.addWizardPage(component, "Start", QInstaller.Introduction);
  QMessageBox.information("TEST", "TEST", "TEST", QMessageBox.Ok);
  }

the Start.ui i placed in the config path but
nothing happens and the second MessageBox is never shown - the installer seems to be crashed

• function Controller()
  {
  }
  Controller.prototype.IntroductionPageCallback = function()
  {
  installer.addWizardPageItem(component ,"lineEdit",QInstaller.TargetDirectory);
  }

same - nothing happens here installer crashed

hope you can help me to fix the code - and can someone please tell me how to change the language while the installer is running?

thanks a lot
