1 Qt 4.3.1 is a bug-fix release. It maintains both forward and backward |
|
2 compatibility (source and binary) with Qt 4.3.0. |
|
3 |
|
4 The Qt version 4.3 series is binary compatible with the 4.2.x, 4.1.x and |
|
5 4.0.x series. Applications compiled for Qt 4.0, 4.1 or 4.2 will continue to |
|
6 run with Qt 4.3. |

432 * New example, showing how to use QSslSocket to communicate over an |
|
433 encrypted (SSL) connection. |
|
434 |
|
435 - Accelerated Screen Driver |
|
436 * Ensured that the example does not crash if it is unable to get a |

445 |
|
446 * [163862] Fixed a bug where QClipboard would escape all non-ASCII |
|
447 characters that were copied from GTK+ applications. |
|
448 * [165182] Fixed building with the Intel C++ Compiler for Linux on |
|
449 IA-64 (Itanium) (missing functions in qatomic_ia64.h) |
|
450 * [163861] Fixed building on AIX 5.3 where the _POSIX_MONOTONIC_CLOCK |
|
451 macro was accidentally redefined. |
|
452 * [166650] Fixed a regression from 4.2.3 where calling QWidget::move() |
|
453 in a reimplementation of QWidget::showEvent() did not work. |
|
454 * [166097] QWidget::show() no longer overwrites the _NET_WM_STATE |
|
455 property. Instead, QWidget now merges any existing _NET_WM_STATE |
|
456 property together with its own state. |
|
457 * Fixed the QAtomic implementation on the Alpha, which previously |
|
458 caused all applications to hang on start-up. |
|
459 * [165229] Changed the linux-lsb-g++ specification to avoid linking with |
|
460 libGLU (which is not part of the LSB specification). |
|
461 * [155083, 146833] Ensure that all font substitutions from fontconfig |
|
462 are obeyed by using a strong binding for QFont's family with |
|
463 fontconfig. |
|
464 |
|
465 Windows |
|
466 ------- |
|
467 |
|
468 * [169105] Fixed a regression where calling resize() on a minimized |
|
469 window did not work. |
|
470 * [169376] Fixed a race condition that would cause a crash when |
|
471 stopping timers in a thread. |
|
472 * [165440] Fixed a crash that could occur when using Google's Pinyin |
|
473 input method with Qt. |
|
474 |
|
475 Mac OS X |
|
476 -------- |
|
477 |
|
478 * QMake's Xcode generator is now more robust when determining which |
|
479 version of Xcode projects it should generate. It also uses launch |
|
480 services to determine Xcode's location as well. |
|
481 * Small changes to be more Leopard compatible |
|
482 * [167020] Ensured that the translations are really included in the |
|
483 binary package. |
|
484 * [164530] Ensured that the DPI for fonts don't change when the |
|
485 resolution changes. |
|
486 * [165530] Fixed a bug that caused Q_DECLARE_METATYPE() in a |
|
487 precompiled header to interfere with the Objective-C 'id' keyword. |
|
488 * [165659] Fixed bold/italic font rendering for some fonts. |
|
489 |
|
490 Qtopia Core |
|
491 ----------- |
|
492 |
|
493 * Fixed support for bitmap fonts. |
|
494 * [164297] Fixed a potential crash in accelerated paint engines. |
|
495 * [160970] Fixed support for 1-bit black and white screens. |
|
496 * [164783] Fixed bug in 4-bit grayscale support which resulted in pink |
|
497 colors under certain circumstances. |
|
498 * [164955] Fixed painting error when using QWidget::move(). |
|
499 * [166368] Fixed bug in QWidget::setFixedSize() when using multiple |
|
500 screens. |
|
501 * [165686] Fixed bug in QPixmap::grabWindow() when using multiple |
|
502 screens. |
|
503 * [130925] Fixed use of QWSWindowSurface::move() when acceleration is |
|
504 available. |
|
505 * [143865] Implemented QWSCalibratedMouseHandler::getCalibration() |
|
506 properly to fill all return values. |
|
507 * [161820] Fixed incorrect detection of glib libraries when cross- |
|
508 compiling. |
|
509 * [152914] Improved the framebuffer test example. |
|
510 * [171454] Fixed painting errors when zooming in QVFb. |

|
519 widget in ensureWidgetVisible(). |
