Detailed Description

A collection of grids which is drawn above the map content in a QgsComposerMap.

The grid stack controls which grids are drawn and the order they are drawn in.

Note: added in QGIS 2.5

Constructor & Destructor Documentation

QgsComposerMapGridStack::QgsComposerMapGridStack ( QgsComposerMap * map )

Constructor for QgsComposerMapGridStack.

Parameters

map	QgsComposerMap the grid stack is attached to

Definition at line 36 of file qgscomposermapgrid.cpp.

QgsComposerMapGridStack::~QgsComposerMapGridStack ( )

virtual

Definition at line 42 of file qgscomposermapgrid.cpp.

Member Function Documentation

void QgsComposerMapGridStack::addGrid ( QgsComposerMapGrid * grid )

Adds a new map grid to the stack and takes ownership of the grid.

The grid will be added to the end of the stack, and rendered above any existing map grids already present in the stack.

Parameters

grid	QgsComposerMapGrid to add to the stack

Note: after adding a grid to the stack, updateBoundingRect() and update() should be called for the QgsComposerMap to prevent rendering artifacts

See Also: removeGrid

Definition at line 46 of file qgscomposermapgrid.cpp.

QList< QgsComposerMapGrid * > QgsComposerMapGridStack::asList ( ) const

Returns a list of QgsComposerMapGrids contained by the stack.

Returns: list of grids

Reimplemented from QgsComposerMapItemStack.

Definition at line 84 of file qgscomposermapgrid.cpp.

const QgsComposerMapGrid * QgsComposerMapGridStack::constGrid ( const QString & gridId ) const

Returns a const reference to a grid within the stack.

Parameters

gridId id for the QgsComposerMapGrid to find

Returns: const reference to grid, if found

See Also: grid

Definition at line 66 of file qgscomposermapgrid.cpp.

QgsComposerMapGrid * QgsComposerMapGridStack::grid ( const QString & gridId ) const

Returns a reference to a grid within the stack.

Parameters

gridId id for the QgsComposerMapGrid to find

Returns: reference to grid if found

See Also: constGrid

Definition at line 72 of file qgscomposermapgrid.cpp.

QgsComposerMapGrid * QgsComposerMapGridStack::grid ( const int index ) const

Returns a reference to a grid within the stack.

Parameters

index grid position in the stack

Returns: reference to grid if found

See Also: constGrid

Definition at line 78 of file qgscomposermapgrid.cpp.

double QgsComposerMapGridStack::maxGridExtension ( ) const

Calculates the maximum distance grids within the stack extend beyond the QgsComposerMap's item rect.

Returns: maximum grid extension

Definition at line 123 of file qgscomposermapgrid.cpp.

void QgsComposerMapGridStack::moveGridDown ( const QString & gridId )

Moves a grid down the stack, causing it to be rendered below other grids.

Parameters

gridId id for the QgsComposerMapGrid to move down

Note: after moving a grid within the stack, update() should be called for the QgsComposerMap to redraw the map with the new grid stack order

See Also: moveGridUp

Definition at line 61 of file qgscomposermapgrid.cpp.

void QgsComposerMapGridStack::moveGridUp ( const QString & gridId )

Moves a grid up the stack, causing it to be rendered above other grids.

Parameters

gridId id for the QgsComposerMapGrid to move up

Note: after moving a grid within the stack, update() should be called for the QgsComposerMap to redraw the map with the new grid stack order

See Also: moveGridDown

Definition at line 56 of file qgscomposermapgrid.cpp.

QgsComposerMapGrid & QgsComposerMapGridStack::operator[] ( int idx )

Returns a reference to a grid within the stack.

Parameters

idx	grid position in the stack

Returns: reference to grid if found

See Also: constGrid; grid

Reimplemented from QgsComposerMapItemStack.

Definition at line 99 of file qgscomposermapgrid.cpp.

bool QgsComposerMapGridStack::readXML	(	const QDomElement &	elem,
		const QDomDocument &	doc
	)

overridevirtual

Sets the grid stack's state from a DOM document.

Parameters

elem	is DOM node corresponding to 'a ComposerMap' tag
doc	DOM document

Returns: true if read was successful

See Also: writeXML

Implements QgsComposerMapItemStack.

Definition at line 106 of file qgscomposermapgrid.cpp.

void QgsComposerMapGridStack::removeGrid ( const QString & gridId )

Removes a grid from the stack and deletes the corresponding QgsComposerMapGrid.

Parameters

gridId id for the QgsComposerMapGrid to remove

Note: after removing a grid from the stack, updateBoundingRect() and update() should be called for the QgsComposerMap to prevent rendering artifacts

See Also: addGrid
