Make possible QtLauncher access pages that restrict access based
on the browser being used and/or simply test the browser with
different user agents.

Instead of requiring that QtLauncher is started from the top-level directory by
using a relative path here, I think it would be better to compile the user agent list
into the application using a Qt resource.

This initialization isn't necessary.

The parameter should be a const QString&.

r- until the above issues are addressed. The rest looks good to me! It's great that you're adding this, it really helps for development/testing.

Thanks for the feedback Simon!

Using Qt resource is a good way if I want to only read the data from useragentlist.txt, because afaik we only can open it in ReadOnly mode, so is not possible to store a new user agent in useragentlist at runtime and is needed to recompile if we want the edit the list manually. Do you know if is possible do it usinf Qt Resource or do you have other suggestion? :)

I am using now QSettings to store and keep the data persistence :)

Simplifying the patch to only read and show the user agents from the 
predefined list for this moment.

Safari Develop->User Agent menu

Instead of a combined list and (custom user agent text field)?, I would suggest that we add the sub-menu User Agent to the Develop menu in QtLauncher and that it has at least the same options and behavior as the identical menu found in Safari. This will make QtLauncher consistent with Safari. Notice, the last option in the Safari User Agent menu is "Other..." which opens a dialog with an text field that is initially populated with the value of the currently active user agent string.

I thing it can be considered. Kenneth? Simon?

[Kenneth Rohde Christiansen]

Sounds fine with me!

[Simon Hausmann]

Absolutely! :)

Please create a new bugzilla entry for the custom UA entry
