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).

DONE	QDebugStateSaver	David Faure (https://codereview.qt-project.org/41793), in Qt 5.1

DONE	QMenu: title feature	Kévin Ottens (https://codereview.qt-project.org/49242)
DONE	QMenu: keyboard navigation (from KMenu)	Kevin Ottens
DONE	Create QPA theme plugin for setting KDE palette, font, widget style, etc. (in KDE), will require extensions on the Qt side, look at KGlobalSettings, some of it is there	Kevin Ottens
DONE	Extend QPA theme plugin to use KIconLoader within QIcon::fromTheme()	Kevin Ottens
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
IN PROGRESS	QUrl methods to replace the QUrlPathInfo attempt	David Faure (https://codereview.qt-project.org/44960)
IN PROGRESS	QCommandLineParser	Laszlo Papp (initially) / David Faure (now); see qtbase cli_parser branch (including pending review requests) and libkdeqt5staging in kdelibs
IN PROGRESS	QIcon: support for overlays	Martin Klapetek
TO DO	contribute natural-comparison to Qt5 (see KStringHandler). In Qt there is naturalCompare function but private and not as good as from KStringHandler. Thiago says: add the feature to QCollator. apol: We cannot use QCollator until this is in: https://codereview.qt-project.org/50372, it's left to be seen how we can do this on platforms where ICU is not available.	-	<{{{3}}}>
IN PROGRESS	QLineEdit: support for clear button	Kevin Ottens https://codereview.qt-project.org/53155 + https://codereview.qt-project.org/53073
DONE	QLineEdit: support for text squeezing	Kevin Ottens (only one user and half-broken feature anyway, cancelled)
IN PROGRESS	QLineEdit: support for URL drops (replace existing text, rather than append)	[email protected]
IN PROGRESS	QComboBox: support for URL drops (replace existing text, rather than append)	[email protected]
DONE	QTextEdit: support for place holder text like place holder text in QLineEdit	Benjamin Port (https://codereview.qt-project.org/53423)
IN PROGRESS	qDebug with categories, currently in an addon (playground/qlogger.git). Thiago says ok for QtCore, if it's not a monster	? QTBUG-19536
IN PROGRESS	Rewrite QKeySequence::StandardKey to get the default keys from QPA, not just an enum. In KDE we can make the shortcuts configurable this way.	David Edmundson
IN PROGRESS	QTabBar: port signals from KTabBar	Ivan Komissarov (https://codereview.qt-project.org/#change,29650)
DONE	Add the web color line edit to QColorDialog (KColorDialog has it)	David Gil (https://codereview.qt-project.org/53239) in Qt 5.2
DONE	Add the color picker button to QColorDialog (KColorDialog has it)	David Gil (https://codereview.qt-project.org/53242) in Qt 5.2
TO DO	QToolBar should take its default settings from the global settings when running in a Plasma Workspace session (see loadKDESettings from KToolBar)	Àlex Fiestas	<{{{3}}}>
TO DO	QMainWindow should follow the KDE HIG when changing the window title in a Plasma Workspace session (see KMainWindow::setCaption)	Àlex Fiestas	<{{{3}}}>
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)
IN PROGRESS	Add icons to QLineEdit context menu (via qstyle?)	Aurélien Gâteau (https://codereview.qt-project.org/61221)
IN PROGRESS	Add icons to QTextBrowser context menu (via qstyle?)	Aurélien Gâteau (https://codereview.qt-project.org/#change,61229)
TO DO	Allow to register a default syntax highlighter type for QTextEdit, the KDE backend would register the spell checking one coming from sonnet as default	??	<{{{3}}}>
TO DO	Make sure the QPA plugin can properly react to setting changes	?	<{{{3}}}>
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)
TO DO	Restore QSessionManager from Qt4 that got broken	?	<{{{3}}}>
IN PROGRESS	Extend the QStyle API so that the styleHint() can control the default value for animated widgets (should animate or not by default?)	Àlex Fiestas
TO DO	Extend the QStyle API so that the styleHint() can control the default value QSplitter::opaqueResize	Rohan Garg <[email protected]>	<{{{3}}}>
IN PROGRESS	Make sure QDialogButtonBox Ok button has Ctrl+Return as shortcut. https://codereview.qt-project.org/59140	[email protected]
IN PROGRESS	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	[email protected]
IN PROGRESS	Use Q_PLUGIN_METADATA instead of KPluginInfo	[email protected]
TO DO	Port features of KPrintDialog to QPrintDialog	???	<{{{3}}}>
