Detailed Description
Abstract baseclass for row controllers. A row controller is used by the GraphicsView to nagivate the model and to determine the row geometries.Definition at line 32 of file kdganttabstractrowcontroller.h.

Member Function Documentation
| int AbstractRowController::headerHeight | ( | ) | const [pure virtual] |
- Returns:
- The height of the header part of the view.
Implemented in KDGantt::ListViewRowController, and KDGantt::TreeViewRowController.
| QModelIndex AbstractRowController::indexAbove | ( | const QModelIndex & | idx | ) | const [pure virtual] |
- Returns:
- The modelindex for the previous row before idx.
- See also:
- QTreeView::indexAbove
Implemented in KDGantt::ListViewRowController, and KDGantt::TreeViewRowController.
| virtual QModelIndex KDGantt::AbstractRowController::indexAt | ( | int | height | ) | const [pure virtual] |
Implemented in KDGantt::ListViewRowController, and KDGantt::TreeViewRowController.
| QModelIndex AbstractRowController::indexBelow | ( | const QModelIndex & | idx | ) | const [pure virtual] |
- Returns:
- The modelindex for the next row after idx.
- See also:
- QTreeView::indexBelow
Implemented in KDGantt::ListViewRowController, and KDGantt::TreeViewRowController.
| bool AbstractRowController::isRowVisible | ( | const QModelIndex & | idx | ) | const [pure virtual] |
- Returns:
- true if the row containing index idx is visible in the view.
Implemented in KDGantt::ListViewRowController, and KDGantt::TreeViewRowController.
| virtual int KDGantt::AbstractRowController::maximumItemHeight | ( | ) | const [pure virtual] |
Implemented in KDGantt::ListViewRowController, and KDGantt::TreeViewRowController.
| Span AbstractRowController::rowGeometry | ( | const QModelIndex & | idx | ) | const [pure 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); }
Implemented in KDGantt::ListViewRowController, and KDGantt::TreeViewRowController.
