IWizard->IWizardFactory

Browse Source 
Start at splitting up the wizard functionality a bit. Currently
it is a factory but also contains a lot of logic that is invoked by
the real wizard dialogs.

This change renames/moves a couple of things only.

\class Core::IWizardFactory
\mainclass
\brief The class IWizardFactory is the base class for all wizard factories
(for example shown in \gui {File | New}).
The wizard interface is a very thin abstraction for the \gui{New...} wizards.
Basically it defines what to show to the user in the wizard selection dialogs,
and a hook that is called if the user selects the wizard.
Wizards can then perform any operations they like, including showing dialogs and
creating files. Often it is not necessary to create your own wizard from scratch,
instead use one of the predefined wizards and adapt it to your needs.
To make your wizard known to the system, add your IWizardFactory instance to the
plugin manager's object pool in your plugin's initialize function:
\code
bool MyPlugin::initialize(const QStringList &arguments, QString *errorString)
{
// ... do setup
addAutoReleasedObject(new MyWizardFactory);
// ... do more setup
}
\endcode
\sa Core::BaseFileWizard
\sa Core::StandardFileWizard
*/
/*!
\enum Core::IWizardFactory::WizardKind
Used to specify what kind of objects the wizard creates. This information is used
to show e.g. only wizards that create projects when selecting a \gui{New Project}
menu item.
\value FileWizard
The wizard creates one or more files.
\value ClassWizard
The wizard creates a new class (e.g. source+header files).
\value ProjectWizard
The wizard creates a new project.

/*!
\fn Kind IWizardFactory::kind() const
Returns what kind of objects are created by the wizard.
\sa Kind
*/
/*!
\fn QIcon IWizardFactory::icon() const
Returns an icon to show in the wizard selection dialog.
*/
/*!
\fn QString IWizardFactory::description() const
Returns a translated description to show when this wizard is selected
in the dialog.
*/
/*!
\fn QString IWizardFactory::displayName() const
Returns the translated name of the wizard, how it should appear in the
dialog.
*/
/*!
\fn QString IWizardFactory::id() const
Returns an arbitrary id that is used for sorting within the category.
*/
/*!
\fn QString IWizardFactory::category() const
Returns a category ID to add the wizard to.
*/
/*!
\fn QString IWizardFactory::displayCategory() const
Returns the translated string of the category, how it should appear
in the dialog.
*/
/*!
\fn void IWizardFactory::runWizard(const QString &path,
QWidget *parent,
const QString &platform,
const QVariantMap &variables)
This function is executed when the wizard has been selected by the user
for execution. Any dialogs the wizard opens should use the given \a parent.
The \a path argument is a suggestion for the location where files should be
created. The wizard should fill this in its path selection elements as a
default path.
