Raw Blame History

Qt 4.3.2 is a bug-fix release. It maintains both forward and backward
compatibility (source and binary) with Qt 4.3.0 and Qt 4.3.1.
The Qt version 4.3 series is binary compatible with the 4.2.x, 4.1.x and
4.0.x series. Applications compiled for Qt 4.0, 4.1 or 4.2 will continue to
run with Qt 4.3.

Tools
-----
- Designer
* [175822] Fixed incorrect behavior of the widget editing mode that
could occur when a form was resized.

redone in one go.
Build System
------------

Compiler for Linux. Precompiled header support has been fixed in
this version of the compiler, so the -no-pch workaround is no longer
needed. Note that there is still one outstanding bug in the 64-bit
compiler that requires configuring and building Qt with -debug.

files for cases where the length of the includes exceeds the amount
allowed on the command line.

include files for modules that are not found.
* Fixed generation of dependencies for EXTRA_TARGETS.

pending changes.
* [177165] Fixed a bug that caused minimum column widths to become
independent of the width of the text in the header.

an empty region.

when showing QTreeView with QSortFilterProxyModel and delayed layout
changes were pending.
