How can I set background color/image specific tab at QTabWidget?

Question

After the long visitor status, finally, this is my first post. I create tabs dynamically in my TabWidget(from config). Like; -it is python code, pyqt, answers can be coded c++, dosn’t matter for me :) –

baseWidget = QWidget()
//fill baseWidget with other widgets
window.tabWidget.addTab(baseWidget, _fromUtf8(""))
window.tabWidget.setTabText(window.tabWidget.indexOf(baseWidget), ...)

Then, style via qss, like;

QTabBar::tab {}
QTabBar::tab:selected {}
QTabBar::tab:!selected {}
QTabBar::tab:last {}
QTabBar::tab:first:!selected {}
QTabBar::tab:!selected:hover {}

At this point everything is OK. But, i want to colorize my tabs individually.

How can i achieve this? If it is possible, how can set objectName for a tab?

All post will be appreciated :)

Changing base object name won't help, all you are going to do with base object's stylesheet is to change the content background of that panel.

I did a lot of research and tested a few things regarding your problem and it seems like the only solution is to re-implement the QTabWidget paint event.

I tried somethings that I haven't read anywhere else and it gave some weird results, this approach should've worked. If you want to study it and see for yourself:

tabWidget->setCurrentIndex(0);
tabWidget->tabBar()->setStyleSheet("background-color: red;");

tabWidget->setCurrentIndex(1);
tabWidget->tabBar()->setStyleSheet("background-color: blue;");
