[Qt IFW] How to read command line parameter

[gabrielr]

Hello,

I am using Qt IFW to provide a setup installer to our end users.
I'd like to know if there was a way to read from the controller script a parameter given with the command line.

I'd like to override the target directory:

Controller.prototype.TargetDirectoryPageCallback = function()
{
    // Here, specific code to update the target directory, based
    // on a parameter given in the command line of the installer.
    // The installer could be started with such a command line:
    // my_app_setup.exe --target-directory=/path/to/the/install/directory
    gui.clickButton(buttons.NextButton);
}

Thank you in advance for your answers!
