Date: Sat, 18 Apr 2015 11:33:52 +0300 From: Shinnok <admin@...nnok.com> To: john-dev@...ts.openwall.com Subject: Re: Improving Johnny Hey Mathieu, I can't really do that estimation for you, what I can estimate is my efforts which aren't that useful for you. I suggest you try and evaluate yourself and the tasks at hand so that you can come up with estimates that pertain to you. This way you learn what each task implies more deeply, learn a bit more about Johnny and JtR as you try to figure out what each task is about and also get to evaluate yourself more. Don't overthink it though, come up with a plan and we can revise it afterwards. I suggest you focus on this and your finals in the next week so that you don't feel overloaded.

I apply a translator, call the QT built-in method retranslateUi and everything layout correctly except the listWidgetTabs. As you can see on the screenshot http://i.imgur.com/8yZ0vkb.jpg <http://i.imgur.com/8yZ0vkb.jpg> <http://i.imgur.com/8yZ0vkb.jpg <http://i.imgur.com/8yZ0vkb.jpg>> , the listWidgetTabs object don't resize correctly when we add a bigger text than it previously contained(french word "Mot de passe" is bigger than "Password"). The rest of the screen looks great with translation because the layouts do their jobs and there are no hardcoded values. > > > > > > I tried to force relayout by calling update, updateGeometry, repaint and doing similar to what Aleksey did. However, it doesn't work. It only works when you read the settings and translate the application in main.cpp, before MainWindow is created.

The proper fix for this with Qt >= 5.2.0 is to set QListWidget::SizeAdjustPolicy to QAbstractScrollArea::AdjustToContents.

As a general rule of thumb in UI design, we should never use a max constraint anywhere unless that's really the last resort.
