KDGantt::AbstractGrid Class Reference
#include <KDGanttAbstractGrid>
Detailed Description
Abstract baseclass for grids. A grid is used to convert between QModelIndex'es and gantt chart values (doubles) and to paint the background and header of the view.

Constructor & Destructor Documentation
| AbstractGrid::AbstractGrid | ( | QObject * | parent = 0 |
) |
Constructor. Creates an AbstractGrid with parent parent. The QObject parent is not used for anything internally.

| AbstractGrid::~AbstractGrid | ( | ) | [virtual] |
Destructor. Does nothing

Member Function Documentation
| void KDGantt::AbstractGrid::gridChanged | ( | ) | [signal] |
| bool AbstractGrid::isSatisfiedConstraint | ( | const Constraint & | c | ) | const |
- Returns:
- true if the startpoint is before the endpoint of the constraint c.
Definition at line 84 of file kdganttabstractgrid.cpp.
| bool AbstractGrid::mapFromChart | ( | const Span & | span, | |
| const QModelIndex & | idx, | |||
| const QList< Constraint > & | constraints = QList<Constraint>() | |||
| ) | const [pure virtual] |
Implement this to update the model data based on the location of the item. Check against the constraints list to make sure no hard constraints are violated by writing back to the model.
- Returns:
- true if the update succeeded.
Implemented in KDGantt::DateTimeGrid.
| Span AbstractGrid::mapToChart | ( | const QModelIndex & | idx | ) | const [pure virtual] |
Implement this to map from the data in the model to the location of the corresponding item in the view.
Implemented in KDGantt::DateTimeGrid.
| QAbstractItemModel * AbstractGrid::model | ( | ) | const |
- Returns:
- The QAbstractItemModel used by this grid
Definition at line 62 of file kdganttabstractgrid.cpp.
| void AbstractGrid::paintGrid | ( | QPainter * | painter, | |
| const QRectF & | sceneRect, | |||
| const QRectF & | exposedRect, | |||
| AbstractRowController * | rowController = 0, |
|||
| QWidget * | widget = 0 | |||
| ) | [pure virtual] |
Implement this to paint the background of the view -- typically with some grid lines.
- Parameters:
-
painter -- the QPainter to paint with. sceneRect -- the total bounding rectangle of the scene. exposedRect -- the rectangle that needs to be painted. rowController -- the row controller used by the view -- may be 0. widget -- the widget used by the view -- may be 0.
Implemented in KDGantt::DateTimeGrid.
| void AbstractGrid::paintHeader | ( | QPainter * | painter, | |
| const QRectF & | headerRect, | |||
| const QRectF & | exposedRect, | |||
| qreal | offset, | |||
| QWidget * | widget = 0 | |||
| ) | [pure virtual] |
Implement this to paint the header part of the view.
- Parameters:
-
painter -- the QPainter to paint with. headerRect -- the total rectangle occupied by the header. exposedRect -- the rectangle that needs to be painted. offset -- the horizontal scroll offset of the view. widget -- the widget used by the view -- may be 0.
Implemented in KDGantt::DateTimeGrid.
| QModelIndex AbstractGrid::rootIndex | ( | ) | const |
| void AbstractGrid::setModel | ( | QAbstractItemModel * | model | ) | [virtual, slot] |
Sets the QAbstractItemModel used by this grid implementation. This is called by the view, you should never need to call this from client code.
Definition at line 56 of file kdganttabstractgrid.cpp.
| void AbstractGrid::setRootIndex | ( | const QModelIndex & | idx | ) | [virtual, slot] |
Sets the root index used by this grid implementation. This is called by the view, you should never need to call this from client code.
