List of all members.

Public Member Functions
void	configPageApply ()
	Indicates that the current state of the config page must be saved (applied).
QtilitiesCategory	configPageCategory () const
	Gets the category of the config page.
QIcon	configPageIcon () const
	Gets the icon used for the page in the configuration widget.
void	configPageInitialize ()
	Initialization function where you can do any initialization required by your page.
QString	configPageTitle () const
	Gets the title of the config page.
QWidget *	configPageWidget ()
	Gets widget used in the configuration page area.
QObject *	objectBase ()
	Returns the QObject* base of the interface.
const QObject *	objectBase () const
	Returns a const QObject* base of the interface.
bool	supportsApply () const
	Indicates if the page supports apply operations. When a page only displays information, ExtensionSystemConfig, we don't want the apply button to be active. This function thus controls the activity of the apply button.

virtual QString	configPageHelpID () const
	Gets the help ID of the config page.
virtual void	configPageRestoreDefaults ()
	Indicates that the defaults of the page must be restored.
virtual void	setConfigPageCategory (const QtilitiesCategory &category)
	Sets the category of the config page.
virtual void	setConfigPageHelpID (const QString &config_help_id)
	Sets the help ID of the config page.
virtual void	setConfigPageIcon (const QIcon &icon)
	Sets the icon used for the page in the configuration widget.
virtual bool	supportsRestoreDefaults () const
	Indicates if the page supports restoration of default settings.
Public Member Functions inherited from Qtilities::Core::Interfaces::IObjectBase
QString	objectOriginID () const
	Allows interfaces to provide some sort of source identification.
void	setObjectOriginID (const QString &object_origin_id)
	Allows setting of the object source ID of this interface implementation.

Detailed Description

The ExtensionSystemConfig class provides a ready to use configuration widget for the extension system.

The ExtensionSystemConfig widget exposes settings of the extension system through a configuration page shown below:

Extension System Configuration Widget

To add this page to your application's ConfigurationWidget, do the following:

EXTENSION_SYSTEM->initialize();

// Register extension system config page.
OBJECT_MANAGER->registerObject(EXTENSION_SYSTEM->configWidget());

For more information see the Extension System article.

Member Function Documentation

Qtilities::Core::QtilitiesCategory Qtilities::ExtensionSystem::ExtensionSystemConfig::configPageCategory ( ) const

virtual

Gets the category of the config page.

If you want other parts of your code to be able to modify the category of your page, implement configPageCategory() like this:

if (IConfigPage::configPageCategory().isEmpty())
    return QtilitiesCategory("Your Category");
else
    return IConfigPage::configPageCategory();

If not, just return your caregory.

setConfigPageCategory()

Reimplemented from Qtilities::CoreGui::Interfaces::IConfigPage.

QIcon Qtilities::ExtensionSystem::ExtensionSystemConfig::configPageIcon ( ) const

virtual

Gets the icon used for the page in the configuration widget.

See also:

setConfigPageIcon()

Implements Qtilities::CoreGui::Interfaces::IConfigPage.

void Qtilities::ExtensionSystem::ExtensionSystemConfig::configPageInitialize ( )

virtual

Initialization function where you can do any initialization required by your page.

This function will be called when the configuration widget searches the object pool for config pages. The function will be called on all found pages before adding them to the configuration widget.

In big applications where many configuration pages exists, it makes sense to make use of this function in order to speed up the launch time of your application. Without this function, you will typically initialize your config pages in their constructors. Thus, all the pages will be set up during application launch even if the user never goes to the configuration page. This function provides a solution to that problem where pages will only be initialized when the configuration widget is actually used.

Note:

The default implementation does nothing.

This function was added in Qtilities v1.2.

Reimplemented from Qtilities::CoreGui::Interfaces::IConfigPage.

const QObject* Qtilities::ExtensionSystem::ExtensionSystemConfig::objectBase ( ) const

inlinevirtual

Returns a const QObject* base of the interface.

This function can be used in const methods, but make sure that you don't modify things that should stay const. An example where this is used is when we want to get a property on an object in a const method. This is a const operation.

Implements Qtilities::Core::Interfaces::IObjectBase.
