Constructor.

Creates a new KDGantt::GraphicsView with parent parent.

◆ ~GraphicsView()

GraphicsView::~GraphicsView ( )

override

Destroys this view.

Member Function Documentation

◆ activated

void GraphicsView::activated ( const QModelIndex & index )

signal

◆ addConstraint()

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.

void GraphicsView::print	(	QPainter *	painter,
		const QRectF &	targetRect = `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.

		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.

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.

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

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.

◆ setHeaderContextMenuPolicy()

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 568 of file kdganttgraphicsview.cpp.

◆ setItemDelegate

void GraphicsView::setItemDelegate ( ItemDelegate * delegate )

slot

See also: ItemDelegate and QAbstractItemDelegate.

Definition at line 494 of file kdganttgraphicsview.cpp.

References d, and QObject::qobject_cast().

◆ setModel

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 KDGantt::ItemDataRole.

◆ setReadOnly

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.

References d, and QObject::qobject_cast().

◆ setRootIndex

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().

References d, and QObject::qobject_cast().

◆ setRowController

void GraphicsView::setRowController ( AbstractRowController * rowcontroller )
