Release 5.0.2
===================
Bug Fixes
---------
1. QwtPlotCurve::Xfy curve type fixed
2. Memory leak in QwtLegend fixed
3. Vertical alignment of rich texts fixed
4. Workaround for a Qt4 bug added, that produces horrible performance
when painting curves with a pen width > 1.
5. Background for the tracker text of QwtPickers fixed.
Improved (faster + better rendered texts) implementation of
painting tracker texts, using capabilities of Qt >= 4.3.
6. QwtArrowButton/QwtCounter: workaround for layout bug ( Qt < 4.3 )
of the Cleanlook style added.
7. A couple of minor fixes
Changes
-------
1. QSvgGenerator added to the bode example
Release 5.0.1
===================
Changes
-------
1. A couple of problems, when building Qwt fixed.
2. Displaying Rich Text with Qt 4.x fixed
Release 5.0.0
===================
Platforms
---------
Support of Qt3 and Qt4. Qt2 is not supported any longer.
Key features
------------
1. Redesign of plot items. Makes it much easier to develop
individual items.
2. Redesign of the scale classes. All calculations are
collected in scale engines, where the application can
implement it´s own (f.e log2, or date scales). Now it´s
also possible to have individual and completely irregular scales
3. Redesign of the QwtText classes. The MathML renderer of
the Qt4 solutions package is embedded.
work for all expressions/situations.
4. New classes for navigating: QwtPanner, QwtMaginfier
5. Spectrogram/Contour plots and other classes for displaying
raster data added.
Changes
-------
5.0.0 is by far the release with the most changes in the history of Qwt
- too many to make list.
Release 4.2.0/0.4.2
===================
License
--------
A couple of exceptions to the LGPL with the intention to allow static
linking with commercial applications. See COPYING.
Key features:
-------------
1. Designer plugin
2. Rich Text support ( f.e. E = m * c<sup>2</sup> ) added.
3. QwtDial class family added (QwtDial, QwtCompass, QwtAnalogClock, ...)
4. QwtPicker class family added. Includes QwtPlotZoomer, a complete
implementation of recursive zooming.
5. Device metrics independent printing of QwtPlot. (QPrinter::HighResolution)
6. QwtPlot::setCurveBrush(), QwtCurve::setBrush() added. The area
between curve and baseline will be filled with this brush.
7. Rotation of axis tick labels added. Very useful for axis with long
labels like time scales ...
8. Added a new abstract QwtData class to plot data from almost any type of
container class.
9. QwtDoublePoint, QwtDoubleSize, QwtDoubleRect double counterparts
for QPoint, QSize, QRect.
10. First steps to support Qtopia. All examples can be compiled and started
in the qvfb emulator.
Changes:
---------
1. Rewrite of QwtLegend/QwtLegendItem (no QTable anymore)
2. Each plot item will be painted, even if one of the axis it is
attached to is disabled. (like in all other releases beside 0.4.1)
3. Code for double buffering moved to a new class QwtPaintBuffer.
Double buffering can be enabled/disabled now.
4. QwtPainter, QwtMetricsMap, QwtLayoutMetrics added
Hide paint device metrics dependencies.
5. Layout code rewritten and moved to a new class QwtPlotLayout
New layout options canvasMargin(), alignCanvasToScales()
6. QwtPlot: sizeHint() != minimumSizeHint()
9. Internal plot data are private again. A couple of get methods
added instead.
10. canvas repaints triggered by paint events. Enables event filtering
11. QwtPlot::drawCanvasItems added. In opposite to QwtPlot::drawCanvas
it is used by the printing code too.
12. qwtMax, qwtMin, qwtInt mapped to QMAX, QMIN, qRound from qglobal.h
13. operator= for plot item classes changed.
14. readOnly property added for sliders.
15. valid flag added for QwtDblRange
16. QwtCounter wrap around policy: a counter under- or overflow sets
focus to the smallest up/down button and disables counting.
A space bar keypress release event re-enables counting.
17. QwtPushButton added. A class that adds rich text and alignments
features to QPushButton, like they are used in QLabel
18. Clipped painting code moved from QwtCurve to QwtPainter/QwtRect
19. Canvas cache added to optimize trivial repaints.
20. QwtPlot::drawCurve added for incremental curve data
21. QwtSliderBase, readOnly, isValid added
22. Added filtering of the colors of the title and scales to QwtPrintFilter.
23. Support of QT_NO_CAST_ASII and QT_NO_COMPAT added
24. Batch file added for generating Visual Studio project files
25. QwtPlotCurve, QwtPlotMarker, QwtPlotGrid: more methods public
26. QwtPlot::setLegendPosition added
27. A lot of changes I don't remember, ... sorry.
Bugfixes:
---------
1. Autodetection of painter redirection. QPixmap::grabWidget() works
with Qwt Widgets again.
2. QwtSlider: Rounding double->int conversions instead of simple casts.
3. Bad additional line, connected to the first curve point, when zooming
deep, fixed.
4. QwtMarker: Painting of symbols with width != height fixed
5. QwtPlot::plotMouseXXX/canvasMap pixel coordinates synced.
Now both include the canvas frame.
6. Layout fixed for QwtScaleDraws without tick labels
8. Tab focus chains fixed, focus indications added.
9. Support QwtAutoScale::Inverted when autoScale is off also.
10. Keyboard control, focus indications added.
11. Improved QStyle awareness.
12. Printing of plots with disabled axes
Examples
--------
1. New example linux/cpustat added. Runs also on non linux boxes
with dummy values. Beside showing a couple of features that
are new with 0.4.1 and 0.4.2, it shows how to extend and customize
a QwtPlots.
2. Added new example event_filter to demonstrate event filtering.
This example shows how to add additional controls to the scales,
how to translate mouse clicks on the scales into signals and
how to move points on the canvas.
3. realtime example shows how to use scrollbars when zooming
Release 0.4.1
============
Changes:
---------
1. Platform independent project files. makefiles directory removed.
2. RPM spec file template added.
3. __declspec formalism added for Win32 DLLs. Requires
'DEFINES += QWT_DLL' in the .pro file.
4. QString used for visible texts.
5. Code for error curves removed. These type of features should be
implemented in derived curve classes.
6. A lot of Qt 1.2 related code removed/replaced.
7. QwtColorFilter, QwtPixFrame removed. QwtPlotPixFrame renamed
to QwtPlotCanvas.
8. qmodules.h aware. Skips QwtLegend in case of !QT_MODULE_TABLE
9. All Widgets including QwtPlot optimized to reduce flicker
during resize/repaint.
10. QwtPlot curves/markers can be disabled/enabled to hide/show individual
curves without removing the curves from the plot.
11. Internal maps removed from QwtCurve. QwtCurve::setMap, QwtCurve::setRect,
QwtCurve::setRange removed.
Feature additions:
------------------
1. Printing
QwtPlot::print prints to any type of QPaintDevice now.
Hardcoded printer attributes margin, creator and document title have
been removed and must/can be set by the applications now.
Printing of background and legends added. QwtColorFilter replaced
by QwtPlotPrintFilter.
2. Layout
Many layout fixes and additions. Now all Widgets behave well in
QLayouts and provide sensible sizeHints. QwtPlot::setMargin(int) added.
Fieldwidth added for QwtPlot::setAxisFormat for application that need
range independent width. Title and axis title are Qt:Alignment aware.
Qt::WordBreak or multiline titles are possible.
3. Legend
En/Disabling of single curves in the legend added.
QwtPlot::setAutoLegend added.
4. Extensibility
QwtPlot::insertCurve + QwtPlot::insertMarker added. Now derived
classes of QwtPlotCurve and QwtPlotMarker can be added. Virtual
methods provided by QwtPlotCurve for sub-classing.
QwtScale::setScaleDraw + QwtPlot::setAxisScaleDraw + some virtual
methods for QwtScaleDraw added. Application can implement individual
axis labels now.
5. Sliders
QWheelEvent added. The MouseWheel stepsize is controlled by the
Scroll Page Size. QwtWheel::setWheelWidth added. QwtKnob::setSymbol,
QwtKnob::symbol added.
Bugfixes:
---------
1. Workaround for spontanous curves resulting from overruns
when zooming too deep.
2. Wrong QColorGroup::ColorRole for background colors fixed.
Necessary for several non default QStyles.
3. QwtWheel fixed for vertical wheels. Better color support.
4. QwtSlider fixed.
5. Many forgotten others
Release 0.4.0
============
Bugfixes:
---------
1. A few occurences of the boolean literal \c false were changed into macro
\c FALSE for cross compiler compatibility.
2. A few local variables in member functions were renamed to suppress
warnings issued by really picky compilers about global/class variables
being hidden.
3. In qwt_legend.h, a fully qualified name was used in a class declaration.
The HPUX compiler chokes on this (and it's ugly), so it was fixed.
4. Macro M_2PI is now only defined is this hasn't already been done by the
system's clib.
Feature additions:
------------------
1. Qwt now works with Qt3.0. In order to achieve this, QwtLegend now no
longer derives from QTableView, but from QTable. This seems to have had
quite a few consequences. Kudo's to Uwe Rathmann for uploading this nice
fix to the CVS tree.
2. Getters for a plot's title and title font have been added.
