Frameworks/Epics/Contributions to Qt5

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 QMimeType David Faure, change 15585, in Qt 5.0
DONE KUrl/QUrl merge David Faure and Thiago Macieira (QUrl), in Qt 5.0
DONE KDebug features into QDebug Started by Kai Koehne (Nokia) in change 13433, then Wolfgang Beck implemented category logging (13226), and an addon for the API (see QTBUG-19536). Missing API in Qt itself -> 5.1
DONE Native event filtering in QCoreApplication David Faure, change 29260, in Qt 5.0
DONE QSignalSpy::wait (replaces kWaitForSignal) David Faure, change 30799, in Qt 5.0
DONE Add app display name to window titles David Faure, change 42627, in Qt 5.0
DONE QSaveFile David Faure (, in Qt 5.1
DONE Add a Q_COREAPP_STARTUP_FUNCTION macro which allows to have code called just at the end of QCoreApplicationPrivate::init() David Faure (, in Qt 5.1
DONE QDebugStateSaver David Faure (, in Qt 5.1
DONE K/Q_GLOBAL_STATIC merge Thiago Macieira (, in Qt 5.1
DONE qunsetenv David Faure (, in Qt 5.1
DONE Restore QX11Info, in qtx11extras.git Richard Moore and David Faure (, in Qt 5.1
DONE QLockFile David Faure (, in Qt 5.1
DONE QDebug: coloring the method name (blue for debugs, red for warnings) Olivier Goffart (, in Qt 5.1
DONE QKeySequence to/from string Kévin Ottens
DONE QMenu: title feature Kévin Ottens (
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 (

TO DO QSqueezedTextLabel, or squeezing in QLabel ? <{{{3}}}>
TO DO QFileSystemWatcher: support for watching non-existing files David Faure <{{{3}}}>

DONE QLineEdit: support for text squeezing Kevin Ottens (only one user and half-broken feature anyway, cancelled)
TO DO QLineEdit: support for URL drops (replace existing text, rather than append) ?? <{{{3}}}>

IN PROGRESS qDebug with categories, currently in an addon (playground/qlogger.git), plan is to have it in 5.1 Wolfgang Beck, QTBUG-19536
TO DO Merge KStandardShortcut and QKeySequence::StandardKey ?? <{{{3}}}>

IN PROGRESS QInputDialog should have an equivalent of KInputDialog::getMultiLineText David Gil
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 (
IN PROGRESS For better usability, QInputDialog::getItem should use a QListView instead of a QComboBox, like KInputDialog::getItemList. 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 (
TO DO QFileDialog: add QUrl based API for the non-static use of QFileDialog (as mentionned on ( Kevin Ottens <{{{3}}}>
