[Solved] How to set stylesheet for tab from MdiArea in qss file

Hi,

i have an mdiadrea in my mainwindow (ui->mdiArea ). I want to change the style of
the tabs by a qss file.

The code "QTabBar::tab" is changing all tabs that i have in my application, e.g. in Options Dialog
what i don't want.

Code:

---

QTabBar::tab {
  ...
}

---

How must i change the line

Code:

---

QTabBar::tab {

---

that only the tabs in my ui->mdiArea are changed?

These doesn't work:
QTabBar::tab #MainWindow
QTabBar#MainWindow::tab
QTabBar#mdiArea::tab
QTabBar#ui->mdiArea::tab

Thx
Stefan

this works:

Code:

---

QMdiArea#mdiArea QTabBar::tab

---
