Constructor & Destructor Documentation

◆ QgsLayoutItemPicture()

QgsLayoutItemPicture::QgsLayoutItemPicture ( QgsLayout layout)

Constructor for QgsLayoutItemPicture, with the specified parent layout.

Definition at line 50 of file qgslayoutitempicture.cpp.

Member Function Documentation

◆ applyItemSizeConstraint()

QSizeF QgsLayoutItemPicture::applyItemSizeConstraint ( QSizeF  targetSize)
overrideprotectedvirtual

Applies any item-specific size constraint handling to a given targetSize in layout units.

Subclasses can override this method if they need to apply advanced logic regarding item sizes, which cannot be covered by setFixedSize() or setMinimumSize(). Item size constraints are applied after fixed, minimum and data defined size constraints.

See also
setFixedSize()
setMinimumSize()

Reimplemented from QgsLayoutItem.

Definition at line 206 of file qgslayoutitempicture.cpp.

◆ create()

QgsLayoutItemPicture * QgsLayoutItemPicture::create ( QgsLayout layout)
static

Returns a new picture item for the specified layout.

The caller takes responsibility for deleting the returned object.

Definition at line 78 of file qgslayoutitempicture.cpp.

◆ draw()

void QgsLayoutItemPicture::draw ( QgsLayoutItemRenderContext context)
overrideprotectedvirtual

Draws the item's contents using the specified item render context.

Note that the context's painter has been scaled so that painter units are pixels. Use the QgsRenderContext methods to convert from millimeters or other units to the painter's units.

Implements QgsLayoutItem.

Definition at line 83 of file qgslayoutitempicture.cpp.

◆ finalizeRestoreFromXml()

void QgsLayoutItemPicture::finalizeRestoreFromXml ( )
overridevirtual

Called after all pending items have been restored from XML.

Items 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 from QgsLayoutItem.

Definition at line 824 of file qgslayoutitempicture.cpp.

◆ icon()

QIcon QgsLayoutItemPicture::icon ( ) const
overridevirtual

Returns the item's icon.

Reimplemented from QgsLayoutItem.

Definition at line 73 of file qgslayoutitempicture.cpp.

◆ linkedMap()

QgsLayoutItemMap * QgsLayoutItemPicture::linkedMap ( ) const

Returns the linked rotation map, if set.

An nullptr means map rotation is disabled. If this is set then the picture is rotated by the same amount as the specified map object.

See also
setLinkedMap()

Definition at line 783 of file qgslayoutitempicture.cpp.

◆ mode()

Format QgsLayoutItemPicture::mode ( ) const
inline

Returns the current picture mode (image format).

Definition at line 229 of file qgslayoutitempicture.h.

◆ northMode()

NorthMode QgsLayoutItemPicture::northMode ( ) const
inline

Returns the mode used to align the picture to a map's North.

See also
setNorthMode()
northOffset()

Definition at line 133 of file qgslayoutitempicture.h.

◆ northOffset()

double QgsLayoutItemPicture::northOffset ( ) const
inline

Returns the offset added to the picture's rotation from a map's North.

See also
setNorthOffset()
northMode()

Definition at line 147 of file qgslayoutitempicture.h.

◆ pictureAnchor()

QgsLayoutItem::ReferencePoint QgsLayoutItemPicture::pictureAnchor ( ) const
inline

Returns the picture's current anchor, which controls how it is placed within the picture item's frame.

See also
setPictureAnchor()

Definition at line 175 of file qgslayoutitempicture.h.

◆ picturePath()

QString QgsLayoutItemPicture::picturePath ( ) const

Returns the path of the source image.

Data defined picture source may override this value. The path can either be a local path or a remote (http) path.

Returns
path for the source image
See also
setPicturePath()

Definition at line 678 of file qgslayoutitempicture.cpp.

◆ pictureRotation()

double QgsLayoutItemPicture::pictureRotation ( ) const
inline

Returns the rotation used for drawing the picture within the item's frame, in degrees clockwise.

See also
setPictureRotation()
linkedMap()

Definition at line 106 of file qgslayoutitempicture.h.

◆ pictureRotationChanged

void QgsLayoutItemPicture::pictureRotationChanged ( double  newRotation)
signal

Is emitted on picture rotation change.

◆ readPropertiesFromElement()

bool QgsLayoutItemPicture::readPropertiesFromElement ( const QDomElement &  element,
const QDomDocument &  document,
const QgsReadWriteContext context 
)
overrideprotectedvirtual

Sets item state from a DOM element.

Parameters
elementis the DOM element for the item
documentDOM document
contextread write context

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
writePropertiesToElement()
readXml()

Reimplemented from QgsLayoutItem.

Definition at line 718 of file qgslayoutitempicture.cpp.

◆ recalculateSize

void QgsLayoutItemPicture::recalculateSize ( )
slot

Forces a recalculation of the picture's frame size.

Definition at line 652 of file qgslayoutitempicture.cpp.

◆ refreshDataDefinedProperty

void QgsLayoutItemPicture::refreshDataDefinedProperty ( QgsLayoutObject::DataDefinedProperty  property = QgsLayoutObject::AllProperties)
overrideslot

Definition at line 659 of file qgslayoutitempicture.cpp.

◆ refreshPicture

void QgsLayoutItemPicture::refreshPicture ( const QgsExpressionContext context = nullptr)
slot

Recalculates the source image (if using an expression for picture's source) and reloads and redraws the picture.

Parameters
contextexpression context for evaluating data defined picture sources

Definition at line 334 of file qgslayoutitempicture.cpp.
