Member Function Documentation

acceptDrop()

virtual Q_DECL_DEPRECATED bool QgsCptCityDataItem::acceptDrop ( )

inlinevirtual

Returns true if the item accepts drag & dropped layers - e.g.

for import.

Deprecated:

QGIS 3.40. Is unused and will be removed in QGIS 4.0.

Definition at line 177 of file qgscptcityarchive.h.

addChildItem()

void QgsCptCityDataItem::addChildItem ( QgsCptCityDataItem *  child, bool  refresh = false  )

virtual

Inserts a new child using alphabetical order based on mName, emits necessary signal to model before and after, sets parent and connects signals.

The refresh argument will refresh the populated item by emitting signals to the model.

Definition at line 581 of file qgscptcityarchive.cpp.

beginInsertItems

void QgsCptCityDataItem::beginInsertItems ( QgsCptCityDataItem *  parent, int  first, int  last  )

signal

Emitted before child items are added to this item.

This signal must be followed by endInsertItems().

Parameters

parent	the parent item having children added
first	index of first child item to be added
last	index last child item, after the addition has occurred

See also

endInsertItems()

beginRemoveItems

void QgsCptCityDataItem::beginRemoveItems ( QgsCptCityDataItem *  parent, int  first, int  last  )

signal

Emitted before child items are removed from this data item.

This signal must be followed by endRemoveItems().

Parameters

parent	the parent item having children removed
first	index of first child item to be removed
last	index of the last child item to be removed
