Here is a list of user-visible changes in Qt from 1.0 to 1.1. As
|
||
|
|
usual, we fixed some bugs, made some more speedups, and improved the
|
||
|
|
documentation.
|
||
|
|
|
||
|
|
|
||
|
|
****************************************************************************
|
||
|
|
* Changes that might affect runtime behavior *
|
||
|
|
****************************************************************************
|
||
|
|
|
||
|
|
We've added keyboard interface to more widgets, and changed the
|
||
|
|
default focus policy radically. For example, by default you can TAB
|
||
|
|
to button, but it does not grab focus when you click it. The new
|
||
|
|
QWidget::setFocusPolicy() function can be used to change focus policy
|
||
|
|
for all widgets.
|
||
|
|
|
||
|
|
The font matching algorithm has been tweaked in order to provide more
|
||
|
|
predictable fonts in more cases. For some users (such as those with a
|
||
|
|
75dpi X server and only 100dpi fonts installed) it may change the
|
||
|
|
output of some programs.
|
||
|
|
|
||
|
|
sizeHint() and hence default size has been tweaked for some widgets;
|
||
|
|
QMenuBar and QPushButton in particular.
|
||
|
|
|
||
|
|
|
||
|
|
****************************************************************************
|
||
|
|
* Changes that might generate compile errors *
|
||
|
|
* when compiling old code *
|
||
|
|
****************************************************************************
|
||
|
|
|
||
|
|
We've renamed "declare" in qgeneric.h to Q_DECLARE due to naming
|
||
|
|
conflicts. Though we try to provide backward compatibility, there may
|
||
|
|
be problems for a few programs.
|
||
|
|
|
||
|
|
|
||
|
|
****************************************************************************
|
||
|
|
* Type changes that might generate warnings: *
|

* New classes *

|

|

|
QTabDialog (and QTabBar) provide a tabbed dialog. examples/pref shows
|
||
|
|
simple usage of QTabDialog.
|
||
|
|
|
||
|
|
QMultiLineEditor is the long-awaited multi-line editor.
|
||
|
|
|
||
|
|
QGridLayout provides grid-like geometry management for any widget,
|
||
|
|
with flexible row/column elasticity, minimum and maximum sizes.
|
||
|
|
|
||
|
|
QBoxLayout provides more complex and powerful geometry management:
|
||
|
|
boxes and widgets stacked inside other boxes, and finally a top-level
|
||
|
|
box connected to a widget.
|
||
|
|
|
||
|
|
QToolTip provides tool tips for any widget.
|
||

****************************************************************************
|
||
|
|
* Other changes from 1.0 to 1.1 *
|
||
|
|
****************************************************************************
|
||
|
|
|
||
|
|
Added QApplication::setColorMode() and colorMode().
|
||
|
|
|
||
|
|
Added QColor::setAllocContext() and friends; these functions enable
|
||
|
|
applications to allocate discardable colors and then discard them.
|
||
|
|
|
||
|
|
Removed some GNU-make features from the makefiles.
|
||
|
|
|
||
|
|
Added a QPalette constructor to construct an entire palette from a single
|
||
|
|
background color, for convenience.
|
||
|
|
|
||
|
|
moc output now has a version number #define.
|
||
|
|
|
||
|
|
AIX support added. IRIX and NetBSD fixed.
|
||
|
|
|
||
|
|
Rewrote a couple of functions to work around compiler bugs, or
|
||
|
|
purify/boundschecker overzealousness.
|
||
|
|
|
||
|
|
Fixed that ugly man-page SYNOPSIS bug.
|
||
|
|
|
||
|
|
Added the static function QMessageBox::query().
|
||
|
|
|
||
|
|
QRect::unite() now produces the desired results if exactly one of the
|
||
|
|
rectangles is invalid.
|
||
|
|
|
||
|
|
QObject::parent() is now public.
|
||
|
|
|
||
|
|
QPainter::drawWinFocusRect() draws a Windows 95-style focus rectangle.
|
||
|
|
(A focus rectangle can not be drawn using ordinary Windows drawing
|
||
|
|
functions.)
|
||
|
|
|
||
|
|
QApplication::processEvents() added to cater for long-running
|
||
|
|
computations; it processes one round of window system events and
|
||
|
|
timers and then returns.
|
||
|
|
|
||
|
|
QComboBox has been extended to provide an editable combo box and Motif
|
||
|
|
2.x compatible look and feel.
|
||
|
|
|
||
|
|
We've also added a host of new workarounds for bugs in Borland C++,
|
||
|
|
Microsoft VC++, DEC CXX and HP CC.
