1 Here is a list of user-visible changes in Qt from 1.1 to 1.2.  As

     2 usual, we fixed some bugs, made some more speedups, and improved the

     3 documentation.

     4 

     5 

     6 ****************************************************************************

     7 *               Changes that might affect runtime behavior                 *

     8 ****************************************************************************

     9 

    10 QGridLayout::addWidget() and addMultiCellWidget(): The align parameter

    11 is now interpreted correctly. (Previously up/down and right/left were

    12 reversed.) If you have worked around this bug, your widgets may now be

    13 incorrectly aligned.

    14 

    15 QWidget: Every widget is now guaranteed move and resize events. The

    16 event is deferred until the first show(). This may cause problems in

    17 rare cases involving event filters.

    18 

    19 ****************************************************************************

    20 *               Changes that might generate compile errors                 *

    21 *                        when compiling old code                           *

    22 ****************************************************************************

    23 

    24 none

    25 

    26 ****************************************************************************

    27 *               Type changes that might generate warnings:                 *

    28 ****************************************************************************

    29 

    30 none

    31 

    32 ****************************************************************************

    33 * 			Deprecated functions				   *

    34 ****************************************************************************

    35 

    36 QApplication::setColorMode() and colorMode() will be obsoleted. Use

    37 setColorSpec() and colorSpec() instead.

    38 

    39 qchecksum() will be obsoleted. Please use qChecksum() instead.

    40 

    41 ****************************************************************************

    42 * 			     New classes				   *

    43 ****************************************************************************

    44 

    45 QSlider is a widget to input values from a range. If you have been

    46 using a standalone QScrollBar, you will probably want to switch to a

    47 QSlider.

    48 

    49 OpenGL/Mesa support: QGLWidget, QGLContext and QGLFormat. To use these

    50 classes you need to build the Qt/OpenGL library (qgl) in qt/opengl/src.

    51 

    52 ****************************************************************************

    53 *		       Other changes from 1.1 to 1.2			   *

    54 ****************************************************************************

    55 

    56 QApplication::setColorSpec() can specify private colormaps or

    57 non-default visuals

    58 

    59 New function QButton::setAutoRepeat().

    60 

    61 QComboBox: New function currentText(), two new insertion policies:

    62 AfterCurrent and BeforeCurrent.

    66 QFont::key(), new function for caching.

    67 

    68 QFontMetrics::QFontMetrics( const QFont& ) new constructor gives

    69 fontmetrics directly for a font. This is much faster than using

    70 QWidget::fontMetrics() or QPainter::fontmetrics().

    71 

    72 QImage: image load/save functions:

    73 		QImage( const char *filename )

    74 		imageFormat(), load(), loadFromData(), save()

    75 		operator>>(), operator<<()

    76 	XPM support, QImage( const *xpm[] )

    77 	Alpha channel support: 

    78 		hasAlphaBuffer(), setAlphaBuffer()

    79 		createAlphaMask(), 

    80 	Automatic mask generaton: createHeuristicMask() 

    81 	Filling the entire image: fill()

    82 

    83 QLCDNumber now supports filled segments:

    84 	setSegmentStyle(), segmentStyle()

    85 

    86 QLabel now supports accellerated labels:

    87 	setBuddy(), buddy() and a  new constructor.

    88 

    89 QLineEdit new functions:

    90 	show/hide frame: setFrame(), frame()

    91 	password entry mode: setEchoMode(), echoMode()

    92 

    93 QMouseEvent: x() and y() convenience functions.

    94 

    95 QPainter: new constructor QPainter( const QPaintDevice* ) does automatic

    96 begin() and end(). New function	flush().

    97 

    98 QPixmap new functions:

    99 	serialNumber() for caching purposes.

   100 	selfMask()  QPixmap( const char *xpm[] )

   101 	createHeuristicMask()

   102 

   103 QPopupMenu: Added functions to enable checkmarks:

   104 	setCheckable(), isCheckable()

   105 

   106 QScrollBar: sizeHint() implemented.

   107 

   108 QTabBar now supports keyboard input. New function currentTab().

   109 

   110 QTabDialog: new function setOKButton().

   111 

   112 Added support for XFree86 on OS/2.

   113 

   114 New examples:

   115 	examples/tooltip demonstrates dynamic tooltips	

   116 	examples/table demonstrates QTableView

   117 	examples/hello is a different program

   118 

   119 examples/xshape has been removed.
