- splitting of very long documentation pages into walkthroughs
- some writing where it was missing

Author: Volker Hilsheimer <volker.hilsheimer@nokia.com>
Date: Wed Aug 5 00:04:00 2009 +0200
The "buildsystem" docu seems a reasonable start for proper documentation.
Three lists of tools - in the buildsystem table, in the tools-list docu
and implicitly through \ingroup qttools. Needs to be consolidated.

Remove the "Topics" group.
Things are part of frameworks or how-to documentation. Top-level groups are
right now still on the "all overviews" document.

Not sure what it is yet, but definitely not an architecture.
QDataStream links to this page, that might just as well be enough.

Author: Volker Hilsheimer <volker.hilsheimer@nokia.com>
Date: Tue Aug 4 17:43:42 2009 +0200
Use \annotatedlist command to list all widget classes.
Needs nicer formatting, ie qdoc could be \table aware for those lists and
skip the header.

Date: Tue Aug 4 17:21:00 2009 +0200
Move into frameworks.
Add explicitly printed list of classes instead of using a separate
\group page. The \group page is still there as long as qdoc requires it.
Threading and WebKit are still "architectures", coming later.

Split the accessibility docu into a "compared to Qt 3" section, and move
real information into the overview.
commit 6846a1bccf7d212f7ee0471f992cfb16efb71c43
Author: Volker Hilsheimer <volker.hilsheimer@nokia.com>
Date: Mon Aug 3 23:47:37 2009 +0200
The gui-programming seems rather arbitrary and should go away.
Some things fit into the desktop integration, which is probably more a
howto. Focus is a concept in the widgets context, and application-wide
techniques like accelerators should probably be part of the "window"
docu.

Author: Volker Hilsheimer <volker.hilsheimer@nokia.com>
Date: Sun Aug 2 16:56:41 2009 +0200
A new layout for the examples.

Date: Sat Aug 1 21:52:37 2009 +0200
Cleaning up groups of text- and string-related classes.
Make a clear separation between classes that deal with string data (ie
QString, QByteArray, QTextStream) and classes that are part of the "scribe"
framework.
Merge documentation from the Qt 4.0 introduction of Scribe into the
richtext processing guide.
commit 3854592806e23955f69613bdc1e2998d5d6f3a8a
Author: Volker Hilsheimer <volker.hilsheimer@nokia.com>
Date: Sat Aug 1 20:50:06 2009 +0200
One group of thread-related classes should be enough.
commit b8935bc0ec3d33b6a3fe7b3b220b5781ad79d68d
Author: Volker Hilsheimer <volker.hilsheimer@nokia.com>
Date: Sat Aug 1 19:32:21 2009 +0200
Move documentation for classes into same directory as the respective
header files (or implementation file, if one exists).
This follows the Qt standard, and there is no particular reason why .qdoc
files cannot live in src. Since there are a number of .cpp files that have
only documentation it might also be an idea to rename the .qdoc files to
.cpp and add them to the .pro-files to have them included in generated
project files for easier access.

Separate module documentation from frameworks documentation.
Module documentation will list the classes in each module, how to use the
respective libraries and headerfiles from a build-system perspective and
what the legal implications are when linking against those libraries.
The documentation of frameworks lives now in the frameworks subdirectory,
or in dedicated subdirectories for the key frameworks.

Fixes failed queries when mysql auto-prepares
Queries like "Show Index" etc, fail on mysql when automatically prepared
due to a bug in several versions of mysql. Basically anything but a
select query will fail. This fixes this by making the user explicitly
prepare the query if they want to, and the blame then falls on them
if they try and prepare a statement likely to fail. This fix also
seems to result in a speedup for single-execution queries, possibly
due to reduction in roundtrip communications.
All autotests pass & behaviour conforms to documentation.

This follows the Qt standard, and there is no particular reason why .qdoc
files cannot live in src. Since there are a number of .cpp files that have
only documentation it might also be an idea to rename the .qdoc files to
.cpp and add them to the .pro-files to have them included in generated
project files for easier access.

Graphics + View was introduced in Qt 4.2, replacing its predecessor, QCanvas. For + more on Graphics View, see \l{The Graphics View Framework}. + + This document walks through the steps needed, class by class and function + by function, to port a QCanvas application to Graphics View. + + \tableofcontents + + Qt 4.2 provides two complete examples of Q3Canvas applications ported to + Graphics View: + + \list + \o \l{Ported Canvas Example}, the canvas example from Qt 3. + \o \l{Ported Asteroids Example}, the Asteroids game from the Qt 3 demo. + \endlist + + \section1 Introduction + + Conceptually, the Graphics View classes from Qt 4 and the Canvas + classes from Qt 3 provide similar functionality using a similar + design. Instead of "canvas", we use the term "scene". Otherwise, the + class names and functions are almost the same as in Qt 3. The easiest + classes to port will be QCanvas and QCanvasView. Experience shows that + most time is spent porting the item classes, depending on the + complexity of the QCanvasItem classes you have been using before. + + This porting guide will assume you have already ported your + application to Qt 4, by making use of Q3Canvas. If you have not done + so already, as a first step, run the \l qt3to4 tool on your + project. This tool will automate the most tedious part of the porting + effort. + + Some additional steps are usually required before your application + will compile and run. You can read more about the porting process in + \l{Porting to Qt 4}. + + \section1 Porting from Q3Canvas + + QGraphicsScene is the closest equivalent to Q3Canvas. There + are some noticable differences in this new API: Whereas the + Q3Canvas classes use integer precision, QGraphicsScene is + entirely based on double coordinates, with graphical + primitives such as QPointF instead of QPoint, QRectF instead + of QRect, and QPolygonF and QPainterPath. The canvas area is + defined by a scene rectangle, allowing negative coordinates, + as opposed to Q3Canvas, which only defines a size (QSize), and + whose top-left corner is always (0, 0). + + In addition, there is no explicit support for canvas tiles + anymore; see \l{Porting scenes with tiles} for more + information. The chunks-based indexing system has been + replaced with an implicitly maintained internal BSP tree. + + \section2 Porting table + + \table + \header \o Q3Canvas \o QGraphicsScene + + \row \o Q3Canvas::Q3Canvas() \o There is no QPixmap based + constructor, and the concept of tiles is gone. You can use + QGraphicsScene::backgroundBrush to set a brush pattern for + the background, or reimplement + QGraphicsScene::drawBackground() in a QGraphicsScene + subclass (see \l{Porting scenes with tiles}). In addition, + the QGraphicsScene geometry is provided as a full + QRectF. Instead of Q3Canvas(int width, int height), you can + use QGraphicsScene(int top, int left, int width, int + height). + + \row \o Q3Canvas::allItems() \o QGraphicsScene::items() + returns a list of all items on the scene. + + \row \o Q3Canvas::backgroundColor() \o You can assign a color for the + background through the QGraphicsScene::backgroundBrush + or QGraphicsView::backgroundBrush properties. + + \row \o Q3Canvas::backgroundPixmap() \o You can set a tiled + pixmap for the background through + QGraphicsScene::backgroundBrush or + QGraphicsView::backgroundBrush. For more control on the pixmap + positioning, you can reimplement + QGraphicsScene::drawBackground() or + QGraphicsView::drawBackground(). + + \row \o Q3Canvas::chunkSize() \o The closest equivalent to the + chunks size in Q3Canvas is the depth of QGraphicsScene's BSP + tree. QGraphicsScene assigns a depth automatically, and the + size of each scene segment depends on this depth, and + QGraphicsScene::sceneRect(). See + QGraphicsScene::itemIndexMethod. + + \row \o Q3Canvas::collisions() \o QGraphicsScene provides + several means to detect item collisions. The + QGraphicsScene::items() overloads return items that collide + with a point, a rectangle, a polygon, or an arbitrary vector + path (QPainterPath). You can also call + QGraphicsScene::collidingItems() to determine collision with + an item. + + \row \o Q3Canvas::drawArea() \o The QGraphicsScene::render() + function provides the original behavior + Q3Canvas::drawArea(). In addition, you can pass a source + rectangle for rendering only parts of the scene, and a + destination rectangle for rendering onto designated area of + the destination device.

Here is one example of how to implement tile support: + + \snippet doc/src/snippets/code/doc_src_porting4-canvas.qdoc 1 + + Depending on how your scene uses tiles, you may be able to + simplify this approach. In this example, we will try to mimic the behavior + of the Q3Canvas functions. + + We start by creating a subclass of QGraphicsScene ("TileScene"). + In this class, we declare two of the tile + functions from Q3Canvas, and we then add two helper function that returns the + rectangle for a certain tile in our tile pixmap. We will use a + two-dimensional vector of ints to keep track of what tiles should + be used at what parts of the scene. + + \snippet doc/src/snippets/code/doc_src_porting4-canvas.qdoc 2 + + In setTiles(), we store the pixmap and tile properties as + members of the class. Then we resize the tiles vector + to match the width and height of our tile grid. + + \snippet doc/src/snippets/code/doc_src_porting4-canvas.qdoc 3 + + The setTile() function updates the tiles index, and then + updates the corresponding rect in the scene by calling + tileRect(). + + \snippet doc/src/snippets/code/doc_src_porting4-canvas.qdoc 4 + + The first tileRect() function returns a QRect for the tile at + position (x, y). + + \snippet doc/src/snippets/code/doc_src_porting4-canvas.qdoc 5 + + The second tileRect() function returns a QRect for a tile number. + With these functions in place, we can implement the drawBackground() + function. + + \snippet doc/src/snippets/code/doc_src_porting4-canvas.qdoc 6 + + In drawBackground(), we redraw all tiles that have been + exposed by intersecting each tile rect with the exposed background + area. + + \section1 Porting from Q3CanvasView + + The closest equivalent to Q3CanvasView in Graphics View is + called QGraphicsView. In most cases, this is the easiest + class to port. In addition to providing all of Q3CanvasView's + functionality, QGraphicsView includes some useful new features.

You can set the name by calling + \l{QWidget::setObjectName()}{setObjectName()}, and the flags by + calling \l{QWidget::setWindowFlags()}{setWindowFlags()}. + + \row \o Q3CanvasView::canvas() \o QGraphicsView::scene() + returns the scene that is currently associated with the + view. QGraphicsScene also provides the opposite function, + QGraphicsScene::views(), which returns a list of views + observing the scene. + + \row \o Q3CanvasView::inverseWorldMatrix() \o You can call + QGraphicsView::matrix() and QMatrix::inverted(). + QGraphicsView::mapToScene() and QGraphicsView::mapFromScene() + allow transforming of viewport shapes to scene shapes, and + vice versa. + + \row \o Q3CanvasView::setCanvas() \o QGraphicsView::setScene(). + + \row \o Q3CanvasView::setWorldMatrix() \o + QGraphicsView::setMatrix(), QGraphicsView::rotate(), + QGraphicsView::scale(), QGraphicsView::shear() and + QGraphicsView::translate(). + + \row \o Q3CanvasView::worldMatrix() \o QGraphicsView::matrix() + + \row \o Q3CanvasView::drawContents() \o The + QGraphicsView::drawBackground() function draws the background, + QGraphicsView::drawItems() draws the items, and + QGraphicsView::drawForeground() draws the foreground of the + scene in scene coordinates. You can also reimplement these + functions in QGraphicsScene. + + \endtable + + \section2 Other differences + + QGraphicsView can cache the visible contents of the scene, + similar to how Q3Canvas::setDoubleBuffering() could cache the + entire scene contents. You can call + QGraphicsView::setCacheMode() to configure cacheing, and + QGraphicsView::resetCachedContent() invalidates the cache. + + For improved navigation support, you can set a resize or + transformation anchor through QGraphicsView::resizeAnchor and + QGraphicsView::transformationAnchor. This allows you to easily + rotate and zoom the view while keeping the center fixed, or + zooming towards the position under the mouse cursor. In + addition, if you set the QGraphicsView::dragMode of the view, + QGraphicsView will provide rubber band selection or + click-and-pull navigation using the + \l{Qt::OpenHandCursor}{OpenHandCursor} and + \l{Qt::ClosedHandCursor}{ClosedHandCursor} cursors. + + \section1 Porting from Q3CanvasItem + + The closest equivalent to Q3CanvasItem in Graphics View is + called QGraphicsItem. Deriving from this class is very common, + and because of that, porting from Q3CanvasItem often involves + more work than Q3Canvas and Q3CanvasView. + + Q3CanvasItem has become easier to use, easier to subclass, and more + powerful with QGraphicsItem. The key difference from Q3CanvasItem lies + in event propagation and item groups, but you will also find several + convenient new features, such as support for tooltips, cursors, item + transformation and drag and drop. You can read all about QGraphicsItem + in its own class documentation. + + This section starts with a table that shows how to port each function + from Q3CanvasItem to QGraphicsItem.
