Overview

This code snippet demonstrates how to create a tab bar in Qt. Using a TabBar one can arrange widgets on a different page and display them one by one.

Various Function

• To add the Tab in QTabBar.

QString str="tab1";
QString str1="tab2";
QString str2="tab3";
tabbar->addTab(str);
tabbar->addTab(str1);
tabbar->addTab(str2)

• This property is used to shape the tab in TabBar

tabbar->setShape(QTabBar::RoundedWest);
 

• when their are many tabs in widget the it is needed of an tabscroll Bar.When there are too many tabs in a tab bar for its size, the tab bar can either choose to expand its size or to add buttons that allow you to scroll through the tabs.

tabbar->setUsesScrollButtons(1);
