Lancelot/Discover Lancelot/it

La prima sezione ti conduce in un giro guidato su Lancelot. La seconda è dedicata ad opzioni e concetti più avanzati.

Informazioni generali

Introduzione

Lancelot è un menu per il lancio di applicazioni per la KDE Software Compilation.

Lancelot o Kickoff?

Lancelot fornisce molte funzioni ed opzioni di configurazione che Kickoff non ha. Per un confronto più dettagliato vedi il confronto con altri lanciatori.

Kickoff è il menu predefinito per il lancio delle applicazioni per la KDE SC. Per sostituire Kickoff con Lancelot, devi aggiungere quest'ultimo tramite il pannello 'aggiungi oggetti'. Per maggiori informazioni su come aggiungere e rimuovere oggetti dal pannello, vedi Come fare per...con Plasma.

Lancelot o KRunner?

Lancelot può essere utilizzato come sostituto di KRunner. Vedi il confronto con altri lanciatori per un elenco dei vantaggi.

In modo predefinito Lancelot può essere aperto tramite la scorciatoia Alt + F5 (può essere modificata).

Uso di base

Lancelot con le impostazioni predefinite

Quando farai clic sull'icona di lancio che hai aggiunto al pannello, si aprirà il menu Lancelot.

Mostra quattro sezioni: Applicazioni, Computer, Contatti e Documenti.

Sezioni

Applicazioni

La sezione Applicazioni contiene un elenco delle tue applicazioni preferite nella colonna a sinistra e le categorie delle applicazioni in quella a destra. Se l'applicazione che stai cercando non è nell'elenco delle Preferite, puoi navigare tra le categorie sulla destra semplicemente selezionandone una

When you dive into the categories, the Favourites section will disappear to provide more space for the browsing. You can always return to it by using the breadcrumb bar on the top.

Computer

Computer section of Lancelot

The Computer section contains list of defined places (as seen in Dolphin), some useful system applications and a list of storage devices.

You can eject/mount/unmount removable devices directly from the menu just by right-clicking the desired one and choosing the appropriate option from the context menu.

Contacts

The Contacts section shows the list of unread mails from Akonadi (KMail) and online contacts from Kopete.

Documents

The Documents section shows a list of office applications on the left, and a list of currently and recently opened documents on the right.

Searching capabilities

Lancelot provides all searching features KRunner has. You can use it to find applications, to do calculations, execute BASH commands, as a unit converter etc. For more details, see KRunner Usage.

More advanced topics

Advanced UI concepts

No-click activation

In order to reduce repetitive strain injuries produced by clicking the mouse buttons, Lancelot can be operated, if desired, without a single click.

When you hover an item in the menu, a small icon that looks like a target with a mouse cursor drawn in it will appear. Instead of clicking, you can just hover the icon (or the area near it) and the item will be automatically activated.

Adaptive layout

The layout of the menu differs depending on the position of the applet which invoked it.

Always, the closest to the invoking applet (and the mouse cursor) are the section and system buttons, and the search box is on the opposite side since it has the focus by default and you don't need to click it in order to use it.

The sections are also reordered so that the Applications section is the closest to the mouse cursor.

Adaptive item sizes

The less items a list has, the larger the items and bigger the area for clicking.

When there are more items, Lancelot tries to show them all at once by reducing the size. If there are too many items to be shown all at once, the scrollbars are used as a solution.

Customizing the menu

Show sections inside the applet

If you think that the section buttons are too big and would be better if placed inside the panel itself, just right-click the applet, choose Lancelot Launcher settings and Show categories inside the applet.

Show smaller section buttons

If you think that the section buttons are too big, but you don't want to place them inside the panel, just right-click them and choose Make buttons narrower.

Custom system actions

If you don't use session switching (the 'switch user' feature), you can set different actions to the buttons in the bottom part of the window via the General tab of the Lancelot's configuration dialogue.

Custom applications

You can choose which applications to show in the Documents and System sections via the Applications tab of the Lancelot configuration dialogue.

Reordering items

You can change the order of favourite applications just by drag and drop. Mind that for it to work, you need to unlock your desktop first.

Cascading submenus

Some users prefer that the applications subcategories open in separate popups like they are used to from the classic menu from KDE 3. Since KDE SC 4.5, a new experimental feature was added to Lancelot which enables this behaviour.

To enable it, check the Open popups for subcategories option in the Applications tab of Lancelot's configuration dialogue.

Parts of the Lancelot menu on the desktop

It is useful to have things that you use often placed on the desktop or the panel. For more info, see using the Shelf applet
