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

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

documentation.

****************************************************************************

*               Changes that might affect runtime behavior                 *

****************************************************************************

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

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

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

incorrectly aligned.

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

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

rare cases involving event filters.

****************************************************************************

*               Changes that might generate compile errors                 *

*                        when compiling old code                           *

****************************************************************************

none

****************************************************************************

*               Type changes that might generate warnings:                 *

****************************************************************************

none

****************************************************************************

* 			Deprecated functions				   *

****************************************************************************

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

setColorSpec() and colorSpec() instead.

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

****************************************************************************

* 			     New classes				   *

****************************************************************************

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

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

QSlider.

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

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

****************************************************************************

*		       Other changes from 1.1 to 1.2			   *

****************************************************************************

QApplication::setColorSpec() can specify private colormaps or

non-default visuals

New function QButton::setAutoRepeat().

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

AfterCurrent and BeforeCurrent.

QCursor: added new global cursor blankCursor.

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

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

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

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

QImage: image load/save functions:

		QImage( const char *filename )

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

		operator>>(), operator<<()

	XPM support, QImage( const *xpm[] )

	Alpha channel support: 

		hasAlphaBuffer(), setAlphaBuffer()

		createAlphaMask(), 

	Automatic mask generaton: createHeuristicMask() 

	Filling the entire image: fill()

QLCDNumber now supports filled segments:

	setSegmentStyle(), segmentStyle()

QLabel now supports accellerated labels:

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

QLineEdit new functions:

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

	password entry mode: setEchoMode(), echoMode()

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

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

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

QPixmap new functions:

	serialNumber() for caching purposes.

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

	createHeuristicMask()

QPopupMenu: Added functions to enable checkmarks:

	setCheckable(), isCheckable()

QScrollBar: sizeHint() implemented.

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

QTabDialog: new function setOKButton().

Added support for XFree86 on OS/2.

	examples/tooltip demonstrates dynamic tooltips	

	examples/table demonstrates QTableView
