Detailed Description

A delegate that draws unread and total count for StatisticsProxyModel.

The delegate provides the following features:

• Collections with unread items will have the foldername and the unread column marked in bold.
• If a folder is collapsed, the unread and the total column will contain the total sum of all child folders
• It has the possibility to draw the unread count directly after the foldername, see toggleUnreadAfterFolderName().

Example:

Akonadi::EntityTreeView *view = new Akonadi::EntityTreeView( this );
 
Akonadi::StatisticsProxyModel *statisticsProxy = new Akonadi::StatisticsProxyModel( view );
view->setModel( statisticsProxy );
 
Akonadi::CollectionStatisticsDelegate *delegate = new Akonadi::CollectionStatisticsDelegate( view );
view->setItemDelegate( delegate );

Note

This proxy model is intended to be used on top of the EntityTreeModel. One of the proxies between the EntityTreeModel (the root model) and the view must be a StatisticsProxyModel. That proxy model may appear anywhere in the chain.

Constructor & Destructor Documentation

CollectionStatisticsDelegate() [1/2]

CollectionStatisticsDelegate::CollectionStatisticsDelegate ( QAbstractItemView * parent )

explicit

Creates a new collection statistics delegate.

Parameters

parent

The parent item view, which will also take ownership.

Since

4.6

Definition at line 79 of file collectionstatisticsdelegate.cpp.

CollectionStatisticsDelegate() [2/2]

CollectionStatisticsDelegate::CollectionStatisticsDelegate ( QTreeView * parent )

explicit

Creates a new collection statistics delegate.

Parameters

parent

The parent tree view, which will also take ownership.

Definition at line 85 of file collectionstatisticsdelegate.cpp.

~CollectionStatisticsDelegate()

CollectionStatisticsDelegate::~CollectionStatisticsDelegate ( )

overridedefault

Destroys the collection statistics delegate.

Member Function Documentation

initStyleOption()

void CollectionStatisticsDelegate::initStyleOption ( QStyleOptionViewItem * option, const QModelIndex & index ) const

overrideprotectedvirtual

Parameters

option	style option view item
index	model index (QModelIndex)

Reimplemented from QStyledItemDelegate.

Definition at line 127 of file collectionstatisticsdelegate.cpp.

paint()

void CollectionStatisticsDelegate::paint ( QPainter * painter, const QStyleOptionViewItem & option, const QModelIndex & index ) const

overrideprotectedvirtual

Parameters

painter	pointer for QPainter to use in method
option	style options
index	model index (QModelIndex)

Reimplemented from QStyledItemDelegate.

Definition at line 173 of file collectionstatisticsdelegate.cpp.

progressAnimationEnabled()

bool CollectionStatisticsDelegate::progressAnimationEnabled

(

)

const

Definition at line 121 of file collectionstatisticsdelegate.cpp.

setProgressAnimationEnabled()

void CollectionStatisticsDelegate::setProgressAnimationEnabled

(

bool

enable

)

Parameters

enable

new mode of progress animation

Definition at line 105 of file collectionstatisticsdelegate.cpp.

setUnreadCountShown()

void CollectionStatisticsDelegate::setUnreadCountShown

(

bool

enable

)

Sets whether the unread count is drawn next to the folder name.

You probably want to enable this when the unread count is hidden only. This is disabled by default.

Parameters

enable

If true, the unread count is drawn next to the folder name, if false, the folder name will be drawn normally.

Definition at line 93 of file collectionstatisticsdelegate.cpp.

unreadCountShown()

bool CollectionStatisticsDelegate::unreadCountShown

(

)

const

Returns whether the unread count is drawn next to the folder name.

Definition at line 99 of file collectionstatisticsdelegate.cpp.

updatePalette()

void CollectionStatisticsDelegate::updatePalette

(

)

Since

4.9.1

Definition at line 326 of file collectionstatisticsdelegate.cpp.
