"Fossies" - the Fresh Open Source Software Archive

Member "qt-everywhere-src-6.3.1/qtbase/dist/changes-1.30" (25 May 2022, 10500 Bytes) of package /linux/misc/qt-everywhere-src-6.3.1.tar.xz:


As a special service "Fossies" has tried to format the requested text file into HTML format (style: standard) with prefixed line numbers. Alternatively you can here view or download the uninterpreted source code file.

    1 Here is a list of user-visible changes in Qt from 1.2 to 1.30.  As
    2 usual, we fixed some bugs, made some more speedups, and improved the
    3 documentation.
    4 
    5 Keyboard accelerators and traversal are significantly improved.
    6 
    7 Two new extensions included with Qt 1.30. They are not part of the library:
    8 
    9 Netscape plugin support. You can now write portable Netscape plugins
   10 using Qt. See the qt/extensions/nsplugin directory in the distribution.
   11 
   12 The ImageIO extension library gives a framework for adding new image
   13 formats, including PNG and JPEG in this release. See the qt/extensions/imageio
   14 directory in the distribution.
   15 
   16 The OpenGL extension for Qt now resides in qt/extensions.

   19 ****************************************************************************
   20 * 			     New classes				   *
   21 ****************************************************************************
   22 
   23 * QProgressBar displays a progress bar.
   24 
   25 * QProgressDialog uses QProgressBar to give the user feedback during long
   26   operations, as well as a means of aborting.
   27 
   28 * QMovie supports animated GIFs and incremental loading of images.
   29 
   30 * QHBoxLayout and QVBoxLayout are convenience classes giving a simpler
   31   interface to QBoxLayout.
   32 
   33 * QValidator provides a mechanism for validating input.
   34

   37 *		       Enhancements from 1.2 to 1.30			   *
   38 ****************************************************************************
   39 
   40 QFont now supports charsets latin1 through latin9.
   41 
   42 New command-line arguments: -style motif and -style windows are
   43 accepted, as well as -style=motif and -style=windows, -visual, -ncols,
   44 -cmap.
   45 
   46 QMultiLineEdit is usable for much bigger documents than in 1.2
   47 
   48 More sizeHint() functions added, some existing ones tweaked.
   49 
   50 Many widgets have improved look and feel, particularly changes to
   51 Windows GUI style to match Windows more closely.
   52 
   53 Improved Postscript output.
   54 
   55 Color handling has been improved; better 32-to-8 conversion; Qt
   56 prefers to use Macintosh/Netscape color cube in 8-bit mode; more and
   57 better dithering support.
   58 
   59 GIF and PPM support.
   60 
   61 QMessageBox has a number of new static functions to replace the
   62 venerable message(): information(), warning(), critical() and about().
   63 
   64 QPopupMenu can now display icon and text in the same item.
   65 
   66 QPopupMenu::exec() to pop up a synchronous popup menu.
   67 
   68 QListBox now supports multi selection.
   69 
   70 QWidget::setBackgroundMode() gives a powerful way of managing widget
   71 backgrounds, to reduce flicker.
   72 
   73 QWidget::setIcon() now works under both X11 and Windows.
   74 
   75 The file dialog now remembers the previously selected directory.
   76 
   77 QApplication::setWinStyleHighlightColor() sets the highlight color in
   78 windows style.
   79 
   80 QApplication::setDoubleClickInterval() sets the double click timeout
   81 
   82 The layout example is new and more informative.
   83 
   84 There is a new openGL example; extension/opengl/examples/box/ shows
   85 how to control an openGL widget using Qt user interface components.
   86 
   87 
   88 ****************************************************************************
   89 *               Changes that might affect runtime behavior                 *
   90 ****************************************************************************
   91 
   92 Tab/Shift-Tab handling has been improved a lot; this means that
   93 widgets which couldn't get keyboard focus before now can.
   94 
   95 Some widgets (buttons, tab bars, tab dialogs) semi-automatically set
   96 up keyboard accelerators. ( setText("E&xit") will give Alt-X as an
   97 accelerator.)  In some very rare cases, this will cause changes of
   98 behaviour.
   99 
  100 The QColor::light() function now works, and anything which relied on
  101 its buggy behaviour might be a little darker than expected until changed,
  102 usually just recompiling (the default argument has also changed).
  103 
  104 The colors used have been tuned a bit; pixmaps that "know" the RGB
  105 values of colorGroup().background() and the like will look just a tiny
  106 bit wrong.
  107 
  108 QApplication calls setlocale to the local environment, except for
  109 LC_NUMERIC which is set to the C locale. This means that input/output
  110 of floating point numbers will always use '.' as the decimal separator, 
  111 while all other locale dependant operations will use the default locale.
  112

  116 *                        when compiling old code                           *
  117 ****************************************************************************
  118
