Class: QgsPointCloudQueryBuilder

Query Builder for layers.

The query builder allows interactive creation of an expression for limiting the points displayed in a point cloud layer. The point attributes are displayed and value ranges can be viewed to aid in constructing the expression. A test function checks that the typed expression is valid.

Added in version 3.26.
