<div dir="ltr">This should do the trick:

<div>
<div><font face="monospace, monospace">class TabWidget(QtWidgets.QTabWidget):</font></div>
<div><font face="monospace, monospace"> moveRange = None</font></div>

<div><font face="monospace, monospace"> if movable:</font></div>

<div><font face="monospace, monospace"> def eventFilter(self, source, event):</font></div>

<div><font face="monospace, monospace"> if event.type() == QtCore.QEvent.MouseButtonPress and event.buttons() == QtCore.Qt.LeftButton:</font></div>
<div><font face="monospace, monospace"> QtCore.QTimer.singleShot(0, self.setMoveRange)</font></div>
<div><font face="monospace, monospace"> elif event.type() == QtCore.QEvent.MouseButtonRelease:</font></div>
<div><font face="monospace, monospace"> self.moveRange = None</font></div>
<div><font face="monospace, monospace"> elif event.type() == QtCore.QEvent.MouseMove and self.moveRange is not None:</font></div>
<div><font face="monospace, monospace"> if event.x() < self.moveRange[0] or event.x() > self.tabBar().width() - self.moveRange[1]:</font></div>
<div><font face="monospace, monospace"> return True</font></div>
<div><font face="monospace, monospace"> return QtWidgets.QTabWidget.eventFilter(self, source, event)</font></div>
<div><font face="monospace, monospace"><br>
</font></div>
<div><font face="monospace, monospace"> def setMoveRange(self):</font></div>
<div><font face="monospace, monospace"> tabRect = self.tabBar().tabRect(self.currentIndex())</font></div>
<div><font face="monospace, monospace"> pos = self.tabBar().mapFromGlobal(QtGui.QCursor.pos())</font></div>
<div><font face="monospace, monospace"> self.moveRange = pos.x() - tabRect.left(), tabRect.right() - pos.x()</font></div>
</div>
<div><br>
</div>
<div>The delayed setMoveRange() is required since the position of the tab might change if you have tabs that would take more space than available for the QTabBar and the clicked tab is not fully visible.<br>
Keep also in mind that, if that's the case, it might create some issues while moving tabs beyond the limit.</div>
<div>Also, if you move the mouse too fast beyond the limit, the selected bar will be "stuck" according to the last accepted mouseMoveEvent. Maybe this could be fixed by sending a fake QMouseEvent, but I'm not that sure it would make things "easier" (you should
ensure that the tabRect is not yet at the edge of the QTabBar before).<br>
To avoid all that you should probably work harder by subclassing your own QTabBar and then implement mouseMoveEvent all by yourself, but this would also require some very difficult management of the paintEvent too.<br>
</div>
<div>Also, remember that I didn't take into account margins added by styles, nor the possibility of cornerWidget(s).</div>

In the above image you can see that the dragged tab disappears outside the bounds of the tab bar.<br>
