I try (font-weigth: works, but text-align: does not work):

Qt Code: 
  1. QTabBar::tab:text{
  2.         font-weight:bold;
  3.         text-align:left;
  4.     }
To copy to clipboard, switch view to plain text mode 

I try, but it was also not working:

Qt Code: 
  1. QTabBar::tab {
  2.         font-weight:bold;
  3.         text-align:left;
  4.     }
To copy to clipboard, switch view to plain text mode 

My QTabWidget:

Qt Code: 
  1. <item>
  2.      <widget class="QTabWidget" name="tabWidget">
  3.       <widget class="QWidget" name="tab">
  4.        <attribute name="title">
  5.         <string>Tab 1</string>
  6.        </attribute>
  7.       </widget>
  8.       <widget class="QWidget" name="tab_2">
  9.        <attribute name="title">
  10.         <string>Tab 2</string>
  11.        </attribute>
  12.       </widget>
  13.      </widget>
  14.     </item>
To copy to clipboard, switch view to plain text mode 

I also have not found any “property” (<property name=”…”>) that aligns the text.

how to use the “QSS” to align the text of the tabs (QTabBar/QTabWidget) ?
