Member Function Documentation

headerHeight()

int TreeViewRowController::headerHeight ( ) const

overridevirtual

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 43 of file kdgantttreeviewrowcontroller.cpp.

indexAbove()

QModelIndex TreeViewRowController::indexAbove ( const QModelIndex &  idx ) const

overridevirtual

Returns

The modelindex for the previous row before idx.

See also

QTreeView::indexAbove

Implements KDGantt::AbstractRowController.

Definition at line 104 of file kdgantttreeviewrowcontroller.cpp.

References d.

indexAt()

QModelIndex TreeViewRowController::indexAt ( int  height ) const

overridevirtual

Implements KDGantt::AbstractRowController.

Definition at line 82 of file kdgantttreeviewrowcontroller.cpp.

References d, QAbstractItemModel::index(), QModelIndex::isValid(), and QModelIndex::model().

indexBelow()

QModelIndex TreeViewRowController::indexBelow ( const QModelIndex &  idx ) const

overridevirtual

Returns

The modelindex for the next row after idx.

See also

QTreeView::indexBelow

Implements KDGantt::AbstractRowController.

Definition at line 110 of file kdgantttreeviewrowcontroller.cpp.

isRowExpanded()

bool TreeViewRowController::isRowExpanded ( const QModelIndex &  idx ) const

overridevirtual

Implements KDGantt::AbstractRowController.

Definition at line 67 of file kdgantttreeviewrowcontroller.cpp.

References d, QModelIndex::isValid(), and QModelIndex::model().

isRowVisible()

bool TreeViewRowController::isRowVisible ( const QModelIndex &  idx ) const

overridevirtual

Returns

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

Implement this to allow KDGantt to optimize 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 59 of file kdgantttreeviewrowcontroller.cpp.

References d, QModelIndex::isValid(), and QModelIndex::model().

maximumItemHeight()

int TreeViewRowController::maximumItemHeight ( ) const

overridevirtual

Implements KDGantt::AbstractRowController.

Definition at line 49 of file kdgantttreeviewrowcontroller.cpp.

References d.

rowGeometry()

Span TreeViewRowController::rowGeometry ( const QModelIndex &  idx ) const

overridevirtual

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 74 of file kdgantttreeviewrowcontroller.cpp.

References d, QRect::height(), QModelIndex::isValid(), QModelIndex::model(), QRect::translated(), and QRect::y().

totalHeight()

int TreeViewRowController::totalHeight ( ) const

overridevirtual

Returns

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

Implements KDGantt::AbstractRowController.
