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.
|
||
|

|
|
|

|
|
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.
|

QApplication::setColorMode() and colorMode() will be obsoleted. Use
|
||
|
|
setColorSpec() and colorSpec() instead.
|
||
|
|
|
||
|
|
qchecksum() will be obsoleted. Please use qChecksum() instead.

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.
|
||
|
|
|
||
|
|
****************************************************************************
