Member Function Documentation

int ListViewRowController::headerHeight

(

)

const [virtual]

Returns:

The height of the header part of the view.

Implement this to control how much space is reserved at the top of the view for a header

Implements KDGantt::AbstractRowController.

Definition at line 54 of file kdganttlistviewrowcontroller.cpp.

References d.

{
    return d->listview->viewport()->y()-d->listview->frameWidth();
}

QModelIndex ListViewRowController::indexAbove

(

const QModelIndex &

idx

)

const [virtual]

Returns:

The modelindex for the previous row before idx.

See also:

QTreeView::indexAbove

Implements KDGantt::AbstractRowController.

Definition at line 95 of file kdganttlistviewrowcontroller.cpp.

References d.

{
    const QModelIndex idx = d->proxy->mapToSource( _idx );
    return d->proxy->mapFromSource( idx.sibling( idx.row()-1, idx.column()) );
}

QModelIndex ListViewRowController::indexAt

(

int

height

)

const [virtual]

Implements KDGantt::AbstractRowController.

Definition at line 90 of file kdganttlistviewrowcontroller.cpp.

References d.

{
    return d->proxy->mapFromSource( d->listview->indexAt( QPoint( 1,height ) ) );
}

QModelIndex ListViewRowController::indexBelow

(

const QModelIndex &

idx

)

const [virtual]

Returns:

The modelindex for the next row after idx.

See also:

QTreeView::indexBelow

Implements KDGantt::AbstractRowController.

Definition at line 101 of file kdganttlistviewrowcontroller.cpp.

References d.

{
    const QModelIndex idx = d->proxy->mapToSource( _idx );
    if( !idx.isValid() || idx.column()!=0 ) return QModelIndex();
    if( idx.model()->rowCount(idx.parent())<idx.row()+1 ) return QModelIndex();
    return d->proxy->mapFromSource( idx.sibling( idx.row()+1, idx.column()) );
}

bool ListViewRowController::isRowExpanded

(

const QModelIndex &

idx

)

const [virtual]

Implements KDGantt::AbstractRowController.

Definition at line 76 of file kdganttlistviewrowcontroller.cpp.

{
    return false;
}

bool ListViewRowController::isRowVisible

(

const QModelIndex &

idx

)

const [virtual]

Returns:

true if the row containing index idx is visible in the view.

Implement this to allow KDGantt to optimise how items on screen are created. It is not harmful to always return true here, but the View will not perform optimally.

Implements KDGantt::AbstractRowController.

Definition at line 69 of file kdganttlistviewrowcontroller.cpp.

References d.

{
    const QModelIndex idx = d->proxy->mapToSource( _idx );
    assert( idx.isValid() ? ( idx.model() == d->listview->model() ):( true ) );
    return d->listview->visualRect(idx).isValid();
}

int ListViewRowController::maximumItemHeight

(

)

const [virtual]

Implements KDGantt::AbstractRowController.

Definition at line 59 of file kdganttlistviewrowcontroller.cpp.

References d.

{
    return d->listview->fontMetrics().height();
}

Span ListViewRowController::rowGeometry

(

const QModelIndex &

idx

)

const [virtual]

Returns:

A Span consisting of the row offset and height for the row containing idx. A simple implementation might look like

 Span MyRowCtrlr::rowGeometry(const QModelIndex& idx)
 {
      return Span(idx.row()*10,10);
 }

Implements KDGantt::AbstractRowController.

Definition at line 81 of file kdganttlistviewrowcontroller.cpp.

References d, and r.

{
    const QModelIndex idx = d->proxy->mapToSource( _idx );
    assert( idx.isValid() ? ( idx.model() == d->listview->model() ):( true ) );
    QRect r = d->listview->visualRect(idx).translated( QPoint( 0,
                  static_cast<Private::HackListView*>(d->listview)->verticalOffset() ) );
    return Span( r.y(), r.height() );
}

int ListViewRowController::totalHeight

(

)

const [virtual]

Returns:

the total height of the rows. For uniformly sized rows that would be number_of_rows*row_height.

Implements KDGantt::AbstractRowController.

Definition at line 64 of file kdganttlistviewrowcontroller.cpp.

References d.

{
    return d->listview->verticalScrollBar()->maximum()+d->listview->viewport()->height();
}
