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::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::~AbstractGrid ( )

override

Destructor. Does nothing

Definition at line 23 of file kganttabstractgrid.cpp.

Member Function Documentation

drawBackground()

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.

drawForeground()

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.

isSatisfiedConstraint()

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.

mapFromChart() [1/2]

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.

mapFromChart() [2/2]

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.

mapToChart() [1/2]

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.

mapToChart() [2/2]

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.

model()

QAbstractItemModel * AbstractGrid::model

(

)

const

Returns

The QAbstractItemModel used by this grid

Definition at line 35 of file kganttabstractgrid.cpp.

paintGrid()

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.

paintHeader()

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.

rootIndex()

QModelIndex AbstractGrid::rootIndex

(

)

const

Returns

the current root index for this grid

Definition at line 45 of file kganttabstractgrid.cpp.

setModel

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.

setRootIndex

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.
