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 KGantt::AbstractRowController.

Definition at line 37 of file kgantttreeviewrowcontroller.cpp.

indexAbove()

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

overridevirtual

Returns

The modelindex for the previous row before idx.

See also

QTreeView::indexAbove

Implements KGantt::AbstractRowController.

Definition at line 96 of file kgantttreeviewrowcontroller.cpp.

indexAt()

QModelIndex TreeViewRowController::indexAt ( int height ) const

overridevirtual

Implements KGantt::AbstractRowController.

Definition at line 76 of file kgantttreeviewrowcontroller.cpp.

indexBelow()

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

overridevirtual

Returns

The modelindex for the next row after idx.

See also

QTreeView::indexBelow

Implements KGantt::AbstractRowController.

Definition at line 102 of file kgantttreeviewrowcontroller.cpp.

isRowExpanded()

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

overridevirtual

Implements KGantt::AbstractRowController.

Definition at line 61 of file kgantttreeviewrowcontroller.cpp.

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 KGantt 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 KGantt::AbstractRowController.

Definition at line 53 of file kgantttreeviewrowcontroller.cpp.

maximumItemHeight()

int TreeViewRowController::maximumItemHeight ( ) const

overridevirtual

Implements KGantt::AbstractRowController.

Definition at line 43 of file kgantttreeviewrowcontroller.cpp.

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 KGantt::AbstractRowController.

Definition at line 68 of file kgantttreeviewrowcontroller.cpp.

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 KGantt::AbstractRowController.

Definition at line 48 of file kgantttreeviewrowcontroller.cpp.
