It is a convenience wrapper around QAction and QAbstractButton +that lets you integrate those two components easily with polkit. + +polkit-qt-1 is not a direct replacement of polkit-qt: it is based on polkit-1, which is not +backwards compatible in any way with Policykit <= 0.9, which was the backend of polkit-qt. +You are encouraged to port polkit-qt applications to polkit-qt or KAuth, if based on the KDE +Development Platform, since PolicyKit <= 0.9 is no longer maintained. + +polkit-qt-1 is split in three libraries: polkit-qt-core-1, polkit-qt-gui-1 and polkit-qt-agent-1 + +\b polkit-qt-core-1 lets you control actions and authentication without a GUI, with some very +simple functions. It also lets you retrieve and control useful informations on the polkit +authority. You will be mostly interested in the \c Authority class. + +\b polkit-qt-gui-1 lets you easily associate GUI items with polkit actions. Through some simple +wrapper classes you are able to associate QAction and QAbstractButton to a polkit action, +and get their properties changed accordingly to polkit's result. It includes the classes +Action, ActionButton and ActionButtons + +\b polkit-qt-agent-1 lets you write your own polkit authentication agents in a very simple way. + +\li A sample usage of polkit-qt-1 can be found in \ref polkitqt1_example +\li <a href="classes.html">Alphabetical Class List</a> +\li <a href="hierarchy.html">Class Hierarchy</a> + + + + +\page polkitqt1_example Polkit-qt-1 usage example + +You can find an example usage of Polkit-qt-1 in the examples/ dir. You can +build it by passing \c -DBUILD_EXAMPLES=TRUE to your cmake line. The structure +consists of a .ui file and a main class, to demonstrate how easy it is to integrate +polkit support in an existing application. Let's see some details about it: + +\code +bt = new ActionButton(kickPB, "org.qt.policykit.examples.kick", this); +bt->setText("Kick... (long)"); +// here we set the behavior of PolKitResul = No +bt->setVisible(true, Action::No); +bt->setEnabled(true, Action::No); +bt->setText("Kick (long)", Action::No); +bt->setIcon(QPixmap(":/Icons/custom-no.png"), Action::No); +bt->setToolTip("If your admin wasn't annoying, you could do this", Action::No); +// here we set the behavior of PolKitResul = Auth +bt->setVisible(true, Action::Auth); +bt->setEnabled(true, Action::Auth); +bt->setText("Kick... (long)", Action::Auth); +bt->setIcon(QPixmap(":/Icons/action-locked-default.png"), Action::Auth); +bt->setToolTip("Only card carrying tweakers can do this!", Action::Auth); +// here we set the behavior of PolKitResul = Yes +bt->setVisible(true, Action::Yes); +bt->setEnabled(true, Action::Yes); +bt->setText("Kick! (long)", Action::Yes); +bt->setIcon(QPixmap(":/Icons/custom-yes.png"), Action::Yes); +bt->setToolTip("Go ahead, kick kick kick!", Action::Yes); +\endcode + +This small paragraph sets up an action button using an existing button defined in the +UI file, \c kickPB . As you can see, you can set custom properties on your button depending +on the action status/result. The code is mostly self-explainatory + +\code +bt = new ActionButtons(QList<QAbstractButton*>() << listenPB << listenCB, + "org.qt.policykit.examples.listen", this); +bt->setIcon(QPixmap(":/Icons/action-locked.png")); +bt->setIcon(QPixmap(":/Icons/action-unlocked.png"), Action::Yes); +bt->setText("Click to make changes..."); +\endcode + +This demonstrates the use of ActionButtons, that lets you associate multiple buttons with a +single action with extreme ease. \c listenPB and \c listenCB, both defined in the ui file, +are kept in sync with the action. + +\code +connect(bt, SIGNAL(triggered(bool)), this, SLOT(activateAction())); +connect(bt, SIGNAL(clicked(QAbstractButton*,bool)), bt, SLOT(activate())); +connect(bt, SIGNAL(authorized()), this, SLOT(actionActivated())); +\endcode + +Those three signals are all you need to control the action and the activation. Action::triggered() +lets you start the activation/revoke when needed, ActionButton::clicked() lets you do the same thing +with even more ease, just by manually connecting the signal to ActionButton::activate() (see the docs +to understand why this connection doesn't happen automatically), and Action::authorized() signal notifies +you when polkit has authorized you to perform the action. + +As you can see, usage of polkit-qt-1 is extremely simple. Have a look at the complete example +and to the API Docs for more details. + + +*/ + +// DOXYGEN_PROJECTVERSION=0.96.1 +// DOXYGEN_PROJECTNAME=PolkitQt-1 +// DOXYGEN_ENABLE=YES + +// vim:ts=4:sw=4:expandtab:filetype=doxygen |
