From ee9455ed2a83084692d969c398ecb91bcd4fc33a Mon Sep 17 00:00:00 2001 From: Dmitry Zelenkovsky Date: Thu, 28 Apr 2011 11:49:13 +0200 Subject: Support more items for QTextCharFormat::VerticalAlignment enum for custom text objects. * QTextCharFormat::AlignNormal - support text format descent, place text object bottom on (baseline - descent). * QTextCharFormat::AlignBottom - place text object bottom on baseline. * QTextCharFormat::AlignTop - Still not supported. * Any other vertical alignment is mapped QTextCharFormat::AlignBottom. Add new enum AlignBaseline for custom inline objects to take into account font baseline.
