class qgis.gui.QgsPointCloudAttributeComboBox[source]¶

Bases: QComboBox

__init__(parent: QWidget | None = 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.

Parameters:: parent (Optional[QWidget] = None)

allowEmptyAttributeName(self) → bool[source]¶

Returns True if the combo box allows the empty field (“not set”) choice.

setAllowEmptyAttributeName()

Return type:: bool

signal attributeChanged(name: str)[source]¶

Emitted when the currently selected attribute changes.

Parameters:: name (str)

attributes(self) → QgsPointCloudAttributeCollection[source]¶

Returns the attributes currently shown in the combobox.

This will either be attributes from the associated layer() or the attributes manually set by a call to setAttributes().

Return type:: QgsPointCloudAttributeCollection

currentAttribute(self) → str[source]¶

Returns the currently selected attribute

Return type:: str

filters(self) → QgsPointCloudAttributeProxyModel.Filters[source]¶

Returns the current filters used for filtering available attributes.

See also

setFilters()

Return type:: QgsPointCloudAttributeProxyModel.Filters

layer(self) → QgsPointCloudLayer | None[source]¶

Returns the layer currently associated with the combobox.

See also

setLayer()

Return type:: Optional[QgsPointCloudLayer]

setAllowEmptyAttributeName(self, allowEmpty: bool)[source]¶

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

See also

allowEmptyAttributeName()

Parameters:: allowEmpty (bool)

setAttribute(self, name: str | None)[source]¶

Sets the currently selected attribute by name

Parameters:: name (Optional[str])

setAttributes(self, attributes: QgsPointCloudAttributeCollection)[source]¶

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().
