Detailed Description

Widget that allows to navigate through the paths of an URL.

The URL navigator offers two modes:

Editable: Represents the 'classic' mode, where the URL of the location is editable inside a line editor. By pressing RETURN the URL will get activated.
Non editable ("breadcrumb view"): The URL of the location is represented by a number of buttons, where each button represents a path of the URL. By clicking on a button the path will get activated. This mode also supports drag and drop of items.

The mode can be changed by clicking on the empty area of the URL navigator. It is recommended that the application remembers the setting or allows to configure the default mode (see KUrlNavigator::setUrlEditable()).

The URL navigator remembers the URL history during navigation and allows to go back and forward within this history.

In the non editable mode ("breadcrumb view") it can be configured whether the full path should be shown. It is recommended that the application remembers the setting or allows to configure the default mode (see KUrlNavigator::setShowFullPath()).

The typical usage of the KUrlNavigator is:

Create an instance providing a places model and an URL.
Create an instance of QAbstractItemView which shows the content of the URL given by the URL navigator.
Connect to the signal KUrlNavigator::urlChanged() and synchronize the content of QAbstractItemView with the URL given by the URL navigator.

It is recommended, that the application remembers the state of the QAbstractItemView when the URL has been changed. This allows to restore the view state when going back in history. KUrlNavigator offers support for remembering the view state:

The signal urlAboutToBeChanged() will be emitted before the URL change takes places. This allows the application to store the view state by KUrlNavigator::saveLocationState().
The signal urlChanged() will be emitted after the URL change took place. This allows the application to restore the view state by getting the values from KUrlNavigator::locationState().

void KUrlNavigator::saveLocationState ( const QByteArray & state )

Saves the location state described by state for the current location.

It is recommended that at least the scroll position of a view is remembered and restored when traversing through the history. Saving the location state should be done when the signal KUrlNavigator::urlAboutToBeChanged() has been emitted. Restoring the location state (see KUrlNavigator::locationState()) should be done when the signal KUrlNavigator::urlChanged() has been emitted.

Example:

 QByteArray state;
 QDataStream data(&state, QIODevice::WriteOnly);
 data << QPoint(x, y);
 data << ...;
 ...
 urlNavigator::saveLocationState(state);

Sets the home URL used by KUrlNavigator::goHome().

If no home URL is set, the default home path of the user is used.

Since:: 4.5

Definition at line 893 of file kurlnavigator.cpp.

void KUrlNavigator::setLocationUrl ( const KUrl & url ) [slot]

An URL like /home/user/Pictures/2008 is shown as [Pictures] > [2008] in the breadcrumb view, if showing the full path is turned off. If showing the full path is turned on, the URL is shown as [/] > [home] > [Pictures] > [2008].

Since:: 4.2

Definition at line 915 of file kurlnavigator.cpp.

void KUrlNavigator::setUrl ( const KUrl & url ) [slot]

Definition at line 972 of file kurlnavigator.cpp.

KUrl KUrlNavigator::url ( int index ) const

Returns:

The portion of the current URL up to the path part given by index. Assuming that the current URL is /home/peter/Documents/Music, then the following URLs are returned for an index:

index <= 0: /home
index is 1: /home/peter
index is 2: /home/peter/Documents
index >= 3: /home/peter/Documents/Music

Deprecated:: It should not be necessary for a client of KUrlNavigator to query this information.

Definition at line 1187 of file kurlnavigator.cpp.

const KUrl & KUrlNavigator::url ( ) const

Returns:: The current URL of the location.

Deprecated:: Use KUrlNavigator::locationUrl() instead.

Definition at line 1174 of file kurlnavigator.cpp.

void KUrlNavigator::urlAboutToBeChanged ( const KUrl & newUrl ) [signal]

Is emitted, before the location URL is going to be changed to newUrl.

The signal KUrlNavigator::urlChanged() will be emitted after the change has been done. Connecting to this signal is useful to save the state of a view with KUrlNavigator::saveLocationState().

Since:: 4.5

void KUrlNavigator::urlChanged ( const KUrl & url ) [signal]

Is emitted, if the location URL has been changed e.

g. by the user.

See also:: KUrlNavigator::setUrl()

void KUrlNavigator::urlsDropped	(	const KUrl::List &	urls,
		const KUrl &	destination
	)		`[signal]`

Is emitted if the URLs urls have been dropped to the destination destination.

Deprecated:: Use KUrlNavigator::urlsDropped(const KUrl& destination, QDropEvent* event) instead.

void KUrlNavigator::urlsDropped	(	const KUrl &	destination,
		QDropEvent *	event
	)		`[signal]`

Is emitted if a dropping has been done above the destination destination.

The receiver must accept the drop event if the dropped data can be handled.
