| Here is a list of user-visible changes in Qt from 1.2 to 1.30. As |
| usual, we fixed some bugs, made some more speedups, and improved the |
| documentation. |
| |
| Keyboard accelerators and traversal are significantly improved. |
| |
| Two new extensions included with Qt 1.30. They are not part of the library: |
| |
| Netscape plugin support. You can now write portable Netscape plugins |
| using Qt. See the qt/extensions/nsplugin directory in the distribution. |
| |
| The ImageIO extension library gives a framework for adding new image |
| formats, including PNG and JPEG in this release. See the qt/extensions/imageio |
| directory in the distribution. |
| |
| The OpenGL extension for Qt now resides in qt/extensions. |
| |

| **************************************************************************** |
| * New classes * |
| **************************************************************************** |
| |
| * QProgressBar displays a progress bar. |
| |
| * QProgressDialog uses QProgressBar to give the user feedback during long |
| operations, as well as a means of aborting. |
| |
| * QMovie supports animated GIFs and incremental loading of images. |
| |
| * QHBoxLayout and QVBoxLayout are convenience classes giving a simpler |
| interface to QBoxLayout. |
| |
| * QValidator provides a mechanism for validating input. |
| |
| |
| **************************************************************************** |
| * Enhancements from 1.2 to 1.30 * |
| **************************************************************************** |
| |
| QFont now supports charsets latin1 through latin9. |
| |
| New command-line arguments: -style motif and -style windows are |
| accepted, as well as -style=motif and -style=windows, -visual, -ncols, |
| -cmap. |
| |
| QMultiLineEdit is usable for much bigger documents than in 1.2 |
| |
| More sizeHint() functions added, some existing ones tweaked. |
| |
| Many widgets have improved look and feel, particularly changes to |
| Windows GUI style to match Windows more closely. |
| |
| Improved Postscript output. |
| |
| Color handling has been improved; better 32-to-8 conversion; Qt |
| prefers to use Macintosh/Netscape color cube in 8-bit mode; more and |
| better dithering support. |
| |
| GIF and PPM support. |
| |
| QMessageBox has a number of new static functions to replace the |
| venerable message(): information(), warning(), critical() and about(). |
| |
| QPopupMenu can now display icon and text in the same item. |
| |
| QPopupMenu::exec() to pop up a synchronous popup menu. |
| |
| QListBox now supports multi selection. |
| |
| QWidget::setBackgroundMode() gives a powerful way of managing widget |
| backgrounds, to reduce flicker. |
| |
| QWidget::setIcon() now works under both X11 and Windows. |
| |
| The file dialog now remembers the previously selected directory. |
| |
| QApplication::setWinStyleHighlightColor() sets the highlight color in |
| windows style. |
| |
| QApplication::setDoubleClickInterval() sets the double click timeout |
| |
| The layout example is new and more informative. |
| |
| There is a new openGL example; extension/opengl/examples/box/ shows |
| how to control an openGL widget using Qt user interface components. |
| |
| |
| **************************************************************************** |
| * Changes that might affect runtime behavior * |
| **************************************************************************** |
| |
| Tab/Shift-Tab handling has been improved a lot; this means that |
| widgets which couldn't get keyboard focus before now can. |
| |
| Some widgets (buttons, tab bars, tab dialogs) semi-automatically set |
| up keyboard accelerators. ( setText("E&xit") will give Alt-X as an |
| accelerator.) In some very rare cases, this will cause changes of |
| behaviour. |
| |
| The QColor::light() function now works, and anything which relied on |
| its buggy behaviour might be a little darker than expected until changed, |
| usually just recompiling (the default argument has also changed). |
| |
| The colors used have been tuned a bit; pixmaps that "know" the RGB |
| values of colorGroup().background() and the like will look just a tiny |
| bit wrong. |
| |
| QApplication calls setlocale to the local environment, except for |
| LC_NUMERIC which is set to the C locale. This means that input/output |
| of floating point numbers will always use '.' as the decimal separator, |
| while all other locale dependant operations will use the default locale. |
| |
| |
| **************************************************************************** |
| * Changes that might generate compile errors * |
| * when compiling old code * |
| **************************************************************************** |
| |
| none |
