From 5d033928fc94e04cb4d7746dae2269f2be753925 Mon Sep 17 00:00:00 2001 From: Eskil Abrahamsen Blomfeldt Date: Mon, 26 Apr 2010 17:41:47 +0200 Subject: Fix tab stop in QPainter::drawText() Even though we'd set the local tabstops variable to eight times the width of 'x', we'd never use this value anywhere, causing the text layout to use a default value of 80. This looked okay with some font sizes, but since it did not depend on the size of font, the tab in a large font would be too small and potentially the same size or smaller than a single character/space. We enable setting the tabstops on the layout whenever it hasn't been explicitly set on the QTextOption.

When a tabbar had a large number of tabs with short text (5 to 7 characters), no eliding would happen, the window would keep growing until it became wider than the desktop. This commit therefore reduces the minimumSizeHint using more aggressive eliding when eliding is enabled. Also, at some point I had doubts about whether minimumSizeHint took eliding into consideration at all, so I also added a unit-test for minimumSizeHint and sizeHint of tabbars, in various modes.
