Hi,

Is there any way to change the style of QTabWidgets of tabbed QDockWidgets by using a stylesheet?

I tried the following snippet from an official example. I expected the tabs to appear centered, but they remained on the left side. The tabs changed their appearance, so the QTabBar properties are applied - but it seems I can't change the QTabWidget.

Note: I show the tabs above the widgets (setTabPosition(Qt::AllDockWidgetAreas, QTabWidget::North), but that should not make any difference.

thanks in advance...
Felix

Qt Code: 
  1. QTabWidget::pane { /* The tab widget frame */
  2.      border-top: 2px solid #C2C7CB;
  3.      position: absolute;
  4.      top: -0.5em;
  5.  }
  6.  
  7.  QTabWidget::tab-bar {
  8.      alignment: center;
  9.  }
  10.  
  11.  /* Style the tab using the tab sub-control. Note that
  12.      it reads QTabBar _not_ QTabWidget */
  13.  QTabBar::tab {
  14.      background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,
  15.                                  stop: 0 #E1E1E1, stop: 0.4 #DDDDDD,
  16.                                  stop: 0.5 #D8D8D8, stop: 1.0 #D3D3D3);
  17.      border: 2px solid #C4C4C3;
  18.      border-bottom-color: #C2C7CB; /* same as the pane color */
  19.      border-top-left-radius: 4px;
  20.      border-top-right-radius: 4px;
  21.      min-width: 8ex;
  22.      padding: 2px;
  23.  }
  24.  
  25.  QTabBar::tab:selected, QTabBar::tab:hover {
  26.      background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,
  27.                                  stop: 0 #fafafa, stop: 0.4 #f4f4f4,
  28.                                  stop: 0.5 #e7e7e7, stop: 1.0 #fafafa);
  29.  }
  30.  
  31.  QTabBar::tab:selected {
  32.      border-color: #9B9B9B;
  33.      border-bottom-color: #C2C7CB; /* same as pane color */
  34.  }
