Class: QgsPointCloudAttributeComboBox

class qgis.gui.QgsPointCloudAttributeComboBox

Bases: PyQt5.QtWidgets.QComboBox

The QgsPointCloudAttributeComboBox is a combo box which displays the list of attributes of a given point cloud layer. It might be combined with a QgsMapLayerComboBox to automatically update attributes according to a chosen layer.

New in version 3.18.

QgsPointCloudAttributeComboBox(parent: QWidget = None) QgsPointCloudAttributeComboBox creates a combo box to display the fields of a layer. The layer can be either manually given or dynamically set by connecting the signal QgsMapLayerComboBox.layerChanged to the slot setLayer.

setAllowEmptyAttributeName(self, allowEmpty: bool)

Sets whether an optional empty attribute (“not set”) option is shown in the combo box.

Parameters

allowEmpty (bool) –

setAttribute(self, name: str)

Sets the currently selected attribute by name

Parameters

name (str) –

setAttributes(self, attributes: QgsPointCloudAttributeCollection)

Manually sets the attributes to use for the combo box.

This method should only be used when the combo box ISN’T associated with a layer() and needs to show the fields from an arbitrary attribute collection instead. Calling setAttributes() will automatically clear any existing layer().

attributes()

Parameters

attributes (QgsPointCloudAttributeCollection) –

setFilters(self, filters: Union[QgsPointCloudAttributeProxyModel.Filters, QgsPointCloudAttributeProxyModel.Filter])

Sets filters to allow filtering available attributes according to the attribute properties.

Parameters

filters (Union[QgsPointCloudAttributeProxyModel.Filters) –

setLayer(self, layer: QgsMapLayer)

Sets the layer for which fields are listed in the combobox. If no layer is set or a non-point cloud layer is set then the combobox will be empty.
