Detailed Description

An abstract list model for displaying the results of locator searches.

Note that this class should generally be used with a QgsLocatorProxyModel in order to ensure correct sorting of results by priority and match level.

Since

QGIS 3.0

Member Enumeration Documentation

enum QgsLocatorModel::Role

Custom model roles.

Enumerator
ResultDataRole	QgsLocatorResult data.
ResultTypeRole	Result type.
ResultFilterPriorityRole	Result priority, used by QgsLocatorProxyModel for sorting roles.
ResultScoreRole	Result match score, used by QgsLocatorProxyModel for sorting roles.
ResultFilterNameRole	Associated filter name which created the result.
ResultFilterGroupSortingRole	Group results within the same filter results.

slot

Adds a new result to the model.

void QgsLocatorModel::deferredClear

(

)

Resets the model and clears all existing results after a short delay, or whenever the next result is added to the model (whichever occurs first).

Using deferredClear() instead of clear() can avoid the visually distracting frequent clears which may occur if the model is being updated quickly multiple times as a result of users typing in a search query.
