[closed] What is the component name of...
QtCreator has at the left a vertical "strip" (Welcome, Edit, Design, etc...).
What component is that? What is its name?
That would be a sub-class of "QTabWidget":http://qt-project.org/doc/qt-4.8/QTabWidget.html .... I don't think there is a direct component which would give the looks as in QtCreator but you can can make the tabs appear on the left side by using the "TabPosition Enum":http://qt-project.org/doc/qt-4.8/qtabwidget.html#TabPosition-enum in the QTabWidget... For better looks, you will need to sub-class and reimplement lots of stuff...
The name of it is "FancyTabBar", which is a subclass of QWidget.
Ok, thanks a lot :)
