Qt 4.1.4 is a bug-fix release. It maintains both forward and backward compatibility (source and binary) with Qt 4.1.0. The Qt version 4.1 series is binary compatible with the 4.0.x series. Applications compiled for 4.0 will continue to run with 4.1. **************************************************************************** * General * **************************************************************************** Configure / Compilation Compile with -no-qt3support on Windows. Compile on Linux with icc 9.1. Compile on tru64-g++. Compile MySQL plugin with client libraries below MySQL 4.1. Compile SQLite on Tru64 V5.1B with gcc 3.3.4. Compile ODBC plugin on 64-bit Windows. Disable fastcall calling convention on faulty gcc compilers. Demos / Examples Fixed a crash in the Torrent example. Container extension example: Fixed regression that caused Designer to crash when previewing a MultiPageWidget and changing the page. Designer Generate unique object names for splitters. **************************************************************************** * Library * **************************************************************************** General improvements -------------------- - Fixed crash in QGLWidget::makeCurrent() when called from a thread not created with QThread. - Fixed a crash that occurred when writing a PNG image when Qt is built statically. - Fixed Arabic shaping for some fonts. - Limited the character string to 255 characters when writing Type1 fonts to a PostScript file, in accordance with the PostScript specification. - Fixed regression in painting of clipped, cosmetic lines with angles of 0-45 degrees. - Documented the rules for starting and stopping timers in multithreaded applications. - QCommonStyle Added protection against null pointer in pixelMetric() for PM_TabBarTabVSpace. - QDirModel Fixed crash when dragging and dropping a file into a directory. - QHeaderView Fixed painting errors when scrolling a header that has a large number of sections. - QListView Fixed assert when hiding all the rows. Fixed crash when setting the model to a null pointer. - QMainWindow Fixed possible crash when calling setCentralWidget() multiple times. - QPainter Fixed a regression in drawPoint() that caused painting errors when setting the pen width to 0 (e.g. cosmetic pen) and then setting a scale. - QPlastiqueStyle Fixed a regression that caused flat push buttons to be painted like normal push buttons. - QSortFilterProxyModel Emit modelReset() signal when setting a source model. - QTextEdit Ensure that the cursor is visible after dragging & dropping text - QTreeView Fixed potential assert when asking for the coordinates of a non-existing item.

QPaintEngine Support OddEven fill rule. QPainter Fixed a regression that caused drawImage() to ignore the width and height of the source rectangle and draw the whole image without any clipping. Qtopia Core: - Fixed crash due to incorrect assembly code in implementation of q_atomic_swp() for ARM. - Set the Q_PACKED macro when using icc on ARM, so that the generated code is binary compatible with gcc-generated code.
