Contributing to Qt 5 epic

Quite some effort goes into Qt 5 in order to push into Qt some of the features which should be in Qt and not in KDE Frameworks. Usually because all Qt apps would benefit from them even outside the KDE world, and because this cuts dependencies between the KDE frameworks.

Once a class is ready to be contributed into Qt, it can also be added to KDE frameworks in libkdeqt5staging/src, for immediate use in kdelibs-frameworks. When we can depend on the Qt5 version that has the class, we can remove it from libkdeqt5staging.

If the addition to Qt is a new method rather than a new class, then an intermediate solution has to be found (possibly with a different API).

apol: Figuring out how to use it without ICU. https://qt-project.org/wiki/QCollator https://codereview.qt-project.org/#change,63545

DONE QLineEdit: support for clear button Kevin Ottens https://codereview.qt-project.org/53155 + https://codereview.qt-project.org/53073
DONE QTextEdit: support for place holder text like place holder text in QLineEdit Benjamin Port (https://codereview.qt-project.org/53423)

DONE QInputDialog should have an equivalent of KInputDialog::getMultiLineText David Gil (https://codereview.qt-project.org/55905) in Qt 5.2
DONE QInputDialog should have an equivalent of KInputDialog::getDouble with configurable step. RESULT: it's not really used and adding a step parameter or a new method makes the API ugly. Therefore, I abandon the patch. David Gil (https://codereview.qt-project.org/54378)
DONE For better usability, QInputDialog::getItem should use a QListView instead of a QComboBox, like KInputDialog::getItemList. RESULT: Abandoned. Adding another static method to QInputDialog is not needed, since the same result can be achieved with QInputDialog::setOption(QInputDialog::UseListViewForComboBoxItems) David Gil
DONE QFileDialog: add the QUrl equivalents of KFileDialog static methods to QFileDialog, should be possible to specify a optional list of protocols supported by the user code Kevin Ottens (https://codereview.qt-project.org/51031)
DONE QFileDialog: add QUrl based API for the non-static use of QFileDialog (as mentionned on (https://codereview.qt-project.org/51031) Kevin Ottens
DONE Make sure QNetworkAccessManager can list the protocols it supports Kevin Ottens (https://codereview.qt-project.org/51088)
DONE Add icons to QLineEdit context menu (via qstyle?) Aurélien Gâteau (https://codereview.qt-project.org/61221)
DONE Add icons to QTextBrowser context menu (via qstyle?) Aurélien Gâteau (https://codereview.qt-project.org/61229)
DONE Allow to register a default syntax highlighter type for QTextEdit, the KDE backend would register the spell checking one coming from sonnet as default. Change dropped, added a TextEditDecorator class to Sonnet instead Aurélien Gâteau (https://codereview.qt-project.org/62119)
DONE Make sure the QPA plugin can properly react to setting changes Àlex Fiestas
DONE Restore the getenv+unsetenv _NET_STARTUP_INFO from Qt4 that got lost (work for the xcb backend, next step is using it kdbusservice.cpp) David Faure (https://codereview.qt-project.org/54499)
DONE Restore QSessionManager from Qt4 that got broken. David Faure has started some work on this (https://codereview.qt-project.org/61662) https://codereview.qt-project.org/#change,64767 Teo Mrnjavac <teo@kde.org>
DONE Extend the QStyle API so that the styleHint() can control the default value for animated widgets (should animate or not by default?) Àlex Fiestas
DONE Extend the QStyle API so that the styleHint() can control the default value QSplitter::opaqueResize Rohan Garg <rohan@kde.org> (https://codereview.qt-project.org/62207)
DONE Make sure QDialogButtonBox Ok button has Ctrl+Return as shortcut. https://codereview.qt-project.org/59140 aleixpol@kde.org
DONE Port features of KPrintDialog to QPrintDialog Martin Klapetek (in coordination with John Layt and help from Rohan Garg)
DONE Add a "base" property to QSpinBox Kevin Ottens, commit 48e3cc30ed in Qt 5.2
DONE Add MIME Type filtering in QFileDialog David Faure, commit ee9b9d9fd9 in Qt 5.2
DONE QLineEdit should control what shortcuts are overriden, such as Ctrl+U and Ctrl+E. See KLineEdit::overrideShortcut David Edmundson, commit 0b1e30aee in Qt 5.2
DONE Add Banner Page support to the Job tabs Martin Klapetek, in Qt 5.2
DONE Add Page Range support for apps that can't do it themselves (details: http://mail.kde.org/pipermail/kde-frameworks-devel/2013-September/005180.html) Martin Klapetek, in Qt 5.2
DONE Add Page Set support (details: http://mail.kde.org/pipermail/kde-frameworks-devel/2013-September/005180.html) Martin Klapetek, in Qt 5.2
DONE Make PagesPerSheet and PageSet/PageRange mutually exclusive (details: http://mail.kde.org/pipermail/kde-frameworks-devel/2013-September/005180.html) Martin Klapetek, in Qt 5.2
DONE QTimeZone John Layt, in Qt 5.2


Below are the features which we considered adding to Qt, and ended up solving another way:

Status Description Contact
DONE QLineEdit and QComboBox: support for URL drops (replace existing text, rather than append) albertvaka@gmail.com (added in a separate class in kwidgetsaddons: LineEditUrlDropEventFilter)
DONE QTabWidget: give the possibility to hide the tabbar (used in many places if count is 0). Preferably called setTabBarHidden(bool) / isTabBarHidden() (then deprecate ktabwidget). RESULT: Since the exact same functionality can be achieved with tabBar()->hide(bool) and tabBar()->isHidden(), no methods have been added to QTabWidget and both KTabWidget methods have been deprecated. David Gil
DONE Make sure QDesktopServices can list the protocols it supports Kevin Ottens (Turns out it's not even possible to know before hand with xdg-open for a start... It's not really essential anyway: cancelled)
DONE Add support for default vs active shortcuts to QAction (implemented in KActionCollection instead) Kevin Ottens
DONE QLineEdit: support for text squeezing Kevin Ottens (only one user and half-broken feature anyway, cancelled)
DONE QIcon: support for overlays (Unacceptable for Qt, ended up in kf5/kguiaddons - https://git.reviewboard.kde.org/r/112079/) Martin Klapetek
DONE Implement an equivalent of KPluginFactory for the new plugin system so that one module can contain more than one plugin type and create several instance (done in the kservice framework) sebas@kde.org
DONE Use Q_PLUGIN_METADATA instead of KPluginInfo sebas@kde.org

Note: The qpa is withing staging/frameworkintegration/src/platformtheme
