Member Function Documentation

createItem()

GraphicsItem * GraphicsScene::createItem

(

ItemType

type

)

const

Creates a new item of type type.

Definition at line 395 of file kganttgraphicsscene.cpp.

dataIndex()

QModelIndex GraphicsScene::dataIndex ( const QModelIndex &  idx )

static

Returns the index pointing to the last column in the same row as idx. This can be thought of as in "inverse" of mainIndex()

Definition at line 380 of file kganttgraphicsscene.cpp.

getGrid()

const AbstractGrid * GraphicsScene::getGrid

(

)

const

Returns

the current grid.

Definition at line 346 of file kganttgraphicsscene.cpp.

grid()

AbstractGrid * GraphicsScene::grid

(

)

const

Returns

the grid set with setGrid(). Note: Returns nullptr if no grid has been set.

Definition at line 340 of file kganttgraphicsscene.cpp.

print() [1/4]

void GraphicsScene::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 755 of file kganttgraphicsscene.cpp.

print() [2/4]

void GraphicsScene::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 766 of file kganttgraphicsscene.cpp.

print() [3/4]

void GraphicsScene::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 723 of file kganttgraphicsscene.cpp.

print() [4/4]

void GraphicsScene::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 738 of file kganttgraphicsscene.cpp.

printDiagram()

void GraphicsScene::printDiagram	(	QPrinter *	printer,
		const PrintingContext &	context
	)

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

Since

2.8.0

Definition at line 777 of file kganttgraphicsscene.cpp.

setGrid()

void GraphicsScene::setGrid

(

AbstractGrid *

grid

)

Set the grid to grid.

The current grid (if set) is deleted. If grid is nullptr, the scene reverts to use the default_grid

Definition at line 325 of file kganttgraphicsscene.cpp.

takeGrid()

AbstractGrid * GraphicsScene::takeGrid

(

)

Returns

the grid set with setGrid() Note: Returns nullptr if no grid has been set. The scene reverts to use the default_grid.
