Member Function Documentation

◆ addFrame()

void QgsLayoutMultiFrame::addFrame	(	QgsLayoutFrame *	frame,
		bool	recalcFrameSizes = `true`
	)

virtual

Adds a frame to the multiframe.

If recalcFrameSizes is set to true, then a recalculation of all existing frame sizes will be forced.

See also: removeFrame()

Definition at line 56 of file qgslayoutmultiframe.cpp.

◆ beginCommand()

void QgsLayoutMultiFrame::beginCommand	(	const QString &	commandText,
		QgsLayoutMultiFrame::UndoCommand	command = `UndoNone`
	)

Starts new undo command for this item.

The commandText should be a capitalized, imperative tense description (e.g. "Add Map Item"). If specified, multiple consecutive commands for this item with the same command will be collapsed into a single undo command in the layout history.

See also: endCommand(); cancelCommand()

Definition at line 290 of file qgslayoutmultiframe.cpp.

◆ cancelCommand()

void QgsLayoutMultiFrame::cancelCommand ( )

void QgsLayoutMultiFrame::contentsChanged ( )

signal

Emitted when the contents of the multi frame have changed and the frames must be redrawn.

		int	id,
		QUndoCommand *	parent = `nullptr`
	)

overridevirtual

Implements QgsLayoutUndoObjectInterface.

Definition at line 278 of file qgslayoutmultiframe.cpp.

◆ createExpressionContext()

QgsExpressionContext QgsLayoutMultiFrame::createExpressionContext ( ) const

Definition at line 283 of file qgslayoutmultiframe.cpp.

◆ createNewFrame()

QgsLayoutFrame * QgsLayoutMultiFrame::createNewFrame	(	QgsLayoutFrame *	currentFrame,
		QPointF	pos,
		QSizeF	size
	)

Creates a new frame and adds it to the multi frame and layout.

Definition at line 298 of file qgslayoutmultiframe.cpp.

◆ finalizeRestoreFromXml()

void QgsLayoutMultiFrame::finalizeRestoreFromXml ( )

virtual

Called after all pending items have been restored from XML.

Multiframes can use this method to run steps which must take place after all items have been restored to the layout, such as connecting to signals emitted by other items, which may not have existed in the layout at the time readXml() was called. E.g. a scalebar can use this to connect to its linked map item after restoration from XML.

See also: readXml()

Reimplemented in QgsLayoutItemAttributeTable.

Definition at line 310 of file qgslayoutmultiframe.cpp.

◆ findNearbyPageBreak()

double QgsLayoutMultiFrame::findNearbyPageBreak ( double yPos )

virtual

◆ fixedFrameSize()

QSizeF QgsLayoutMultiFrame::fixedFrameSize ( int frameIndex = -1 ) const

Returns: fixed size for frame. If the size has a width or height of 0, then the frame size is not fixed in that direction and frames can have variable width or height accordingly.

See also: minFrameSize(); recalculateFrameRects()

Reimplemented in QgsLayoutTable.

Definition at line 39 of file qgslayoutmultiframe.cpp.

◆ frame()

QgsLayoutFrame * QgsLayoutMultiFrame::frame ( int index ) const

Returns: minimum size for frame. If the size has a width or height of 0, then the frame size has no minimum in that direction.

See also: fixedFrameSize(); recalculateFrameRects()

Reimplemented in QgsLayoutTable.

Definition at line 45 of file qgslayoutmultiframe.cpp.

◆ readPropertiesFromElement()

bool QgsLayoutMultiFrame::readPropertiesFromElement	(	const QDomElement &	element,
		const QDomDocument &	document,

	)

protectedvirtual

Sets multiframe state from a DOM element.

Parameters

element	is the DOM element for the multiframe
document	DOM document

See also: writePropertiesToElement()

Note that item subclasses should not rely on all other items being present in the layout at the time this method is called. Instead, any connections and links to other items must be made in the finalizeRestoreFromXml() method. E.g. when restoring a scalebar, the connection to the linked map's signals should be implemented in finalizeRestoreFromXml(), not readPropertiesFromElement().

See also: readXml()

Reimplemented in QgsLayoutTable, QgsLayoutItemManualTable, QgsLayoutItemHtml, and QgsLayoutItemAttributeTable.

Definition at line 572 of file qgslayoutmultiframe.cpp.

◆ readXml()

This method is useful for multiframes which implement a minFrameSize() or fixedFrameSize() method.

See also: minFrameSize(); fixedFrameSize(); recalculateFrameSizes

Definition at line 227 of file qgslayoutmultiframe.cpp.

◆ recalculateFrameSizes

void QgsLayoutMultiFrame::recalculateFrameSizes ( )

virtualslot

Recalculates the portion of the multiframe item which is shown in each of its component frames.

If the resize mode is set to anything but UseExistingFrames then this may cause new frames to be added or frames to be removed, in order to fit the current size of the multiframe's content.

See also: recalculateFrameRects()

Definition at line 96 of file qgslayoutmultiframe.cpp.

◆ refresh

virtualslot

Refreshes a data defined property for the multi frame by reevaluating the property's value and redrawing the item with this new value.
