Detailed Description

Abstract baseclass for grids. A grid is used to convert between QModelIndex'es and gantt chart values (qreals) and to paint the background and header of the view.

Constructor & Destructor Documentation

AbstractGrid::AbstractGrid ( QObject parent = nullptr)

Constructor. Creates an AbstractGrid with parent parent. The QObject parent is not used for anything internally.

Definition at line 17 of file kganttabstractgrid.cpp.

AbstractGrid::~AbstractGrid ( )
override

Destructor. Does nothing

Definition at line 23 of file kganttabstractgrid.cpp.

Member Function Documentation

void AbstractGrid::drawBackground ( QPainter paint,
const QRectF rect 
)
protectedvirtual
Todo:
document this function

Reimplemented in KGantt::DateTimeGrid.

Definition at line 73 of file kganttabstractgrid.cpp.

void AbstractGrid::drawForeground ( QPainter paint,
const QRectF rect 
)
protectedvirtual
Todo:
document this function

Reimplemented in KGantt::DateTimeGrid.

Definition at line 79 of file kganttabstractgrid.cpp.

bool AbstractGrid::isSatisfiedConstraint ( const Constraint c) const
Returns
true if the startpoint is before the endpoint of the constraint c.

Definition at line 50 of file kganttabstractgrid.cpp.

bool KGantt::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 KGantt::DateTimeGrid.

QVariant AbstractGrid::mapFromChart ( qreal  x) const
virtual

Implement this to map from x to the corresponding location in the view. Return an invalid value if x cannot be mapped.

Reimplemented in KGantt::DateTimeGrid.

Definition at line 67 of file kganttabstractgrid.cpp.

Span KGantt::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 KGantt::DateTimeGrid.

qreal AbstractGrid::mapToChart ( const QVariant value) const
virtual

Implement this to map from value to the corresponding location in the view. Return a negative value if value cannot be mapped. The default implementation returns -1.0.

Reimplemented in KGantt::DateTimeGrid.

Definition at line 61 of file kganttabstractgrid.cpp.

QAbstractItemModel * AbstractGrid::model ( ) const
Returns
The QAbstractItemModel used by this grid

Definition at line 35 of file kganttabstractgrid.cpp.

void KGantt::AbstractGrid::paintGrid ( QPainter painter,
const QRectF sceneRect,
const QRectF exposedRect,
AbstractRowController rowController = nullptr,
QWidget widget = nullptr 
)
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 KGantt::DateTimeGrid.

void KGantt::AbstractGrid::paintHeader ( QPainter painter,
const QRectF headerRect,
const QRectF exposedRect,
qreal  offset,
QWidget widget = nullptr 
)
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 KGantt::DateTimeGrid.

QModelIndex AbstractGrid::rootIndex ( ) const
Returns
the current root index for this grid

Definition at line 45 of file kganttabstractgrid.cpp.

void AbstractGrid::setModel ( QAbstractItemModel model)
virtualslot

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 30 of file kganttabstractgrid.cpp.

void AbstractGrid::setRootIndex ( const QModelIndex idx)
virtualslot

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.
