void LauncherView::clearSelection ()

Clears the current selection.

void LauncherView::clicked ( QContent content )   [signal]

This signal is emitted whenever the user clickes on an item. The activated item is passed as content object.

LauncherView * LauncherView::createLauncherView ( const QByteArray & name, QWidget * parent = 0, Qt::WFlags flags = 0 )   [static]

Returns a new launcher view instance with the given parent and flags. name is the name of the LauncherView subclass to be created.

New launcher view subclasses can be registered via the UIFactory class and UIFACTORY_REGISTER_WIDGET().

    #include "uifactory.h"
    #include "launcherview.h"

    class CustomLauncherView : public LauncherView {



    LauncherView *view = LauncherView::createLauncherView( "CustomLauncherView", parent, flags );

Launcher view instances should be created via this factory method whenever the caller doesn't intend to actually include the declaration for CustomLauncherView.

This function returns a null pointer if name doesn't exist.

void LauncherView::currentChanged ( const QModelIndex & current, const QModelIndex & previous )   [virtual protected slot]

This slot is called when a new item becomes the current item. The previous current item is specified by the previous index, and the new item by the current index.

QModelIndex LauncherView::currentIndex () const

Returns the index of the currently selected item.

const QContent LauncherView::currentItem () const

Returns the currently selected item.

void LauncherView::handleItemPressed ( const QModelIndex & item )   [virtual protected]

This event handler can be reimplemented in a subclass to react when a mouse button is pressed with the specified item.

void LauncherView::handleReturnPressed ( const QModelIndex & item )   [virtual protected]

This event handler can be reimplemented in a subclass to react to Enter or Return key press on the current item. The default implementation emits the clicked() signal.
