dist/changes-1.2 - qt in Qt

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.

New examples:
	examples/tooltip demonstrates dynamic tooltips	
	examples/table demonstrates QTableView
	examples/hello is a different program

examples/xshape has been removed.
