\mainpage Polkit-qt-1 - Qt wrapper around polkit-1

\section polkitqt1_overview Overview

\note Please note that if you're developing an application which can rely not just on Qt modules,
      but also Qt extensions like from the KDE Frameworks, you might want to use instead
      KAuth from KDE Frameworks.

polkit-qt-1 aims to make it easy for Qt developers to take advantage of
polkit API. 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 (from KDE Frameworks),
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= 0.9 is no longer maintained.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 information 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.

\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.
