Close button only for some tabs in Qt

Question

I am using Qt for an assignment I have for college, and I want to use QTabWidget to display a chat window much like Pidgin's. I want to make the "group chat" tab always open and impossible to close and the rest of the "private channel" tabs closable.

QTabWidget's setTabsClosable(bool) is not helping.

Any ideas?

Answer 1

I found an easier solution, I think. Simply access the relevant close button and resize it.

tabWidget->tabBar()->tabButton(0, QTabBar::RightSide)->resize(0, 0);

Answer 2

Find the bar (it is private, so use findChild()) and remove the buttons. Documentation claims that close buttons may be placed on left side too.

QTabBar *tabBar = ui->tabWidget->findChild<QTabBar *>();
tabBar->setTabButton(0, QTabBar::RightSide, 0);
tabBar->setTabButton(0, QTabBar::LeftSide, 0);
