Detailed Description

The GraphicsView class provides a model/view implementation of a gantt chart.

Definition at line 36 of file kganttgraphicsview.h.

Constructor & Destructor Documentation

GraphicsView::GraphicsView ( QWidget parent = nullptr)
explicit

Constructor. Creates a new KGantt::GraphicsView with parent parent.

Definition at line 431 of file kganttgraphicsview.cpp.

GraphicsView::~GraphicsView ( )
override

Destroys this view.

Definition at line 466 of file kganttgraphicsview.cpp.

Member Function Documentation

void GraphicsView::addConstraint ( const QModelIndex from,
const QModelIndex to,
Qt::KeyboardModifiers  modifiers 
)
virtual

Adds a constraint from from to to. modifiers are the keyboard modifiers pressed by the user when the action is invoked.

Override this to control how constraints are added. The default implementation adds a soft constraint unless the Shift key is pressed, in that case it adds a hard constraint. If a constraint is already present, it is removed and nothing is added.

Definition at line 634 of file kganttgraphicsview.cpp.

void GraphicsView::clearItems ( )
protected

Definition at line 684 of file kganttgraphicsview.cpp.

ConstraintModel * GraphicsView::constraintModel ( ) const
Returns
the KGantt::ConstraintModel displayed by this view.

Definition at line 529 of file kganttgraphicsview.cpp.

void GraphicsView::deleteSubtree ( const QModelIndex idx)

Definition at line 754 of file kganttgraphicsview.cpp.

AbstractGrid * GraphicsView::grid ( ) const
Returns
the AbstractGrid used by this view.

Definition at line 598 of file kganttgraphicsview.cpp.

Qt::ContextMenuPolicy GraphicsView::headerContextMenuPolicy ( ) const
Returns
the context menu policy for the header

Definition at line 628 of file kganttgraphicsview.cpp.

void KGantt::GraphicsView::headerContextMenuRequested ( const QPoint pt)
signal

This signal is emitted when the header has contextMenuPolicy Qt::CustomContextMenu and the widget wants to show a context menu for the header. Unlike in QWidget::customContextMenuRequested() signal, pt is here in global coordinates.

QModelIndex GraphicsView::indexAt ( const QPoint pos) const
Returns
The QModelIndex for the item located at position pos in the view or an invalid index if no item was present at that position.

This is useful for for example contextmenus.

Definition at line 673 of file kganttgraphicsview.cpp.

bool GraphicsView::isReadOnly ( ) const
Returns
true if the view is in read-only mode

Definition at line 616 of file kganttgraphicsview.cpp.

ItemDelegate * GraphicsView::itemDelegate ( ) const
Returns
the ItemDelegate used by this view to render items

Definition at line 571 of file kganttgraphicsview.cpp.

QAbstractItemModel * GraphicsView::model ( ) const
Returns
the current model displayed by this view

Note: The returned model is not the model set with setModel()

See also
GraphicsView::setModel

Definition at line 489 of file kganttgraphicsview.cpp.

void GraphicsView::print ( QPrinter printer,
bool  drawRowLabels = true,
bool  drawColumnLabels = true 
)

Print the Gantt chart using printer. If drawRowLabels is true (the default), each row will have it's label printed on the left side. If drawColumnLabels is true (the default), each column will have it's label printed at the top side.

This version of print() will print multiple pages.

Definition at line 760 of file kganttgraphicsview.cpp.

void GraphicsView::print ( QPrinter printer,
qreal  start,
qreal  end,
bool  drawRowLabels = true,
bool  drawColumnLabels = true 
)

Print part of the Gantt chart from start to end using printer. If drawRowLabels is true (the default), each row will have it's label printed on the left side. If drawColumnLabels is true (the default), each column will have it's label printed at the top side.

This version of print() will print multiple pages.

To print a certain range of a chart with a DateTimeGrid, use qreal DateTimeGrid::mapFromDateTime( const QDateTime& dt) const to figure out the values for start and end.

Definition at line 766 of file kganttgraphicsview.cpp.

void GraphicsView::print ( QPainter painter,
const QRectF target = QRectF(),
bool  drawRowLabels = true,
bool  drawColumnLabels = true 
)

Render the GanttView inside the rectangle target using the painter painter. If drawRowLabels is true (the default), each row will have it's label printed on the left side. If drawColumnLabels is true (the default), each column will have it's label printed at the top side.

Definition at line 772 of file kganttgraphicsview.cpp.

void GraphicsView::print ( QPainter painter,
qreal  start,
qreal  end,
const QRectF target = QRectF(),
bool  drawRowLabels = true,
bool  drawColumnLabels = true 
)

Render the GanttView inside the rectangle target using the painter painter. If drawRowLabels is true (the default), each row will have it's label printed on the left side. If drawColumnLabels is true (the default), each column will have it's label printed at the top side.

To print a certain range of a chart with a DateTimeGrid, use qreal DateTimeGrid::mapFromDateTime( const QDateTime& dt) const to figure out the values for start and end.

Definition at line 778 of file kganttgraphicsview.cpp.

void GraphicsView::printDiagram ( QPrinter printer,
const PrintingContext context 
)

Print the Gantt chart on the printer in accordance with the PrintingContext context

Definition at line 784 of file kganttgraphicsview.cpp.

QModelIndex GraphicsView::rootIndex ( ) const
Returns
the rootindex for this view.

Definition at line 547 of file kganttgraphicsview.cpp.

AbstractRowController * GraphicsView::rowController ( ) const
Returns
the AbstractRowController for this view.
See also
setRowController

Definition at line 585 of file kganttgraphicsview.cpp.

QItemSelectionModel * GraphicsView::selectionModel ( ) const
Returns
the QItemSelectionModel used by this view

Definition at line 559 of file kganttgraphicsview.cpp.

void GraphicsView::setConstraintModel ( KGantt::ConstraintModel cmodel)
slot

Sets the constraintmodel displayed by this view.

See also
KGantt::ConstraintModel.

Definition at line 523 of file kganttgraphicsview.cpp.

void GraphicsView::setGrid ( KGantt::AbstractGrid grid)
slot

Sets the AbstractGrid for this view. The grid is an object that controls how QModelIndexes are mapped to and from the view and how the background and header is rendered.

See also
AbstractGrid and DateTimeGrid.

Definition at line 591 of file kganttgraphicsview.cpp.

void GraphicsView::setHeaderContextMenuPolicy ( Qt::ContextMenuPolicy  p)

Sets the context menu policy for the header. The default value Qt::DefaultContextMenu results in a standard context menu on the header that allows the user to set the scale and zoom.

Setting this to Qt::CustomContextMenu will cause the signal headerContextMenuRequested(const QPoint& pt) to be emitted instead.

See also
QWidget::setContextMenuPolicy( Qt::ContextMenuPolicy )

Definition at line 622 of file kganttgraphicsview.cpp.

void GraphicsView::setItemDelegate ( KGantt::ItemDelegate delegate)
slot

Sets the KGantt::ItemDelegate used for rendering items on this view.

See also
ItemDelegate and QAbstractItemDelegate.

Definition at line 565 of file kganttgraphicsview.cpp.

void GraphicsView::setModel ( QAbstractItemModel model)
slot

Sets the model to be displayed in this view to model. The view does not take ownership of the model.

To make a model work well with GraphicsView it must have a certain layout. Whether the model is flat or has a treestrucure is not important, as long as an AbstractRowController is provided that can navigate the model.

GraphicsView operates per row in the model. The data is always taken from the last item in the row. The ItemRoles used are Qt::DisplayRole and the roles defined in KGantt::ItemDataRole.

Note: This model is not returned by model()

See also
GraphicsView::model

Definition at line 474 of file kganttgraphicsview.cpp.

void GraphicsView::setReadOnly ( bool  ro)
slot

Sets the view to read-only mode if to is true. The default is read/write if the model permits it.

Definition at line 610 of file kganttgraphicsview.cpp.

void GraphicsView::setRootIndex ( const QModelIndex idx)
slot

Sets the root index of the model displayed by this view. Similar to QAbstractItemView::setRootIndex, default is QModelIndex().

Definition at line 541 of file kganttgraphicsview.cpp.

void GraphicsView::setRowController ( KGantt::AbstractRowController rowcontroller)
slot

Sets the AbstractRowController used by this view. The AbstractRowController deals with the height and position of each row and with which parts of the model are displayed.

See also
AbstractRowController

Definition at line 577 of file kganttgraphicsview.cpp.

void GraphicsView::setSelectionModel ( QItemSelectionModel model)
