Member Function Documentation

◆ accept()

bool QgsLayoutItemPage::accept ( QgsStyleEntityVisitorInterface visitor) const
overridevirtual

Accepts the specified style entity visitor, causing it to visit all style entities associated with the layout item.

Returns true if the visitor should continue visiting other objects, or false if visiting should be canceled.

QGIS 3.10

Reimplemented from QgsLayoutItem.

Definition at line 235 of file qgslayoutitempage.cpp.

◆ attemptResize()

void QgsLayoutItemPage::attemptResize ( const QgsLayoutSize size,
bool  includesFrame = false 
)
overridevirtual

Attempts to resize the item to a specified target size.

Note that the final size of the item may not match the specified target size, as items with a fixed or minimum size will place restrictions on the allowed item size. Data defined item size overrides will also override the specified target size.

If includesFrame is true, then the size specified by size includes the item's frame.

minimumSize()
fixedSize()
attemptMove()

Reimplemented from QgsLayoutItem.

Definition at line 225 of file qgslayoutitempage.cpp.

◆ decodePageOrientation()

QgsLayoutItemPage::Orientation QgsLayoutItemPage::decodePageOrientation ( const QString &  string,
bool *  ok = nullptr 
)
static

overridevirtual

Gets item display name.

This is the item's id if set, and if not, a user-friendly string identifying item type.

◆ orientation()

QgsLayoutItemPage::Orientation QgsLayoutItemPage::orientation ( ) const

Returns the page orientation.

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().
