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.
