Member Function Documentation

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 54 of file kdgantttreeviewrowcontroller.cpp.

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

overridevirtual

Returns

The modelindex for the previous row before idx.

QTreeView::indexAbove

Implements KDGantt::AbstractRowController.

Definition at line 119 of file kdgantttreeviewrowcontroller.cpp.

References d.

QModelIndex TreeViewRowController::indexAt ( int  height ) const

overridevirtual

Implements KDGantt::AbstractRowController.

Definition at line 93 of file kdgantttreeviewrowcontroller.cpp.

References d.

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

overridevirtual

Returns

The modelindex for the next row after idx.

QTreeView::indexBelow

Implements KDGantt::AbstractRowController.

Definition at line 125 of file kdgantttreeviewrowcontroller.cpp.

References d.

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

overridevirtual

Implements KDGantt::AbstractRowController.

Definition at line 78 of file kdgantttreeviewrowcontroller.cpp.

References d.

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.

int TreeViewRowController::maximumItemHeight ( ) const

overridevirtual

Implements KDGantt::AbstractRowController.

Definition at line 60 of file kdgantttreeviewrowcontroller.cpp.

References d.

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 85 of file kdgantttreeviewrowcontroller.cpp.

References d.

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.
