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.
