Detailed Description

A combobox 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.

Since: QGIS 3.18

Constructor & Destructor Documentation

◆ QgsPointCloudAttributeComboBox()

QgsPointCloudAttributeComboBox::QgsPointCloudAttributeComboBox ( QWidget * parent = nullptr )

explicit

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.

Member Function Documentation

◆ allowEmptyAttributeName()

bool QgsPointCloudAttributeComboBox::allowEmptyAttributeName ( ) const

Returns true if the combo box allows the empty field ("not set") choice.

See also: setAllowEmptyAttributeName()

Definition at line 42 of file qgspointcloudattributecombobox.cpp.

◆ attributeChanged

void QgsPointCloudAttributeComboBox::attributeChanged ( const QString & name )

signal

Emitted when the currently selected attribute changes.

◆ attributes()

QgsPointCloudAttributeCollection QgsPointCloudAttributeComboBox::attributes ( ) const

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().

Definition at line 70 of file qgspointcloudattributecombobox.cpp.

◆ currentAttribute()

QString QgsPointCloudAttributeComboBox::currentAttribute ( ) const

Returns the currently selected attribute.

Definition at line 100 of file qgspointcloudattributecombobox.cpp.

◆ filters()

QgsPointCloudAttributeProxyModel::Filters QgsPointCloudAttributeComboBox::filters ( ) const

inline

Returns the current filters used for filtering available attributes.

See also: setFilters()

Definition at line 59 of file qgspointcloudattributecombobox.h.

◆ layer()

QgsPointCloudLayer * QgsPointCloudAttributeComboBox::layer ( ) const

Returns the layer currently associated with the combobox.

See also: setLayer()

Definition at line 60 of file qgspointcloudattributecombobox.cpp.

◆ setAllowEmptyAttributeName()

void QgsPointCloudAttributeComboBox::setAllowEmptyAttributeName ( bool allowEmpty )

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

See also: allowEmptyAttributeName()

Definition at line 37 of file qgspointcloudattributecombobox.cpp.

◆ setAttribute

void QgsPointCloudAttributeComboBox::setAttribute ( const QString & name )

slot

Sets the currently selected attribute by name.

Definition at line 75 of file qgspointcloudattributecombobox.cpp.

◆ setAttributes()

void QgsPointCloudAttributeComboBox::setAttributes ( const QgsPointCloudAttributeCollection & attributes )

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().

See also: attributes()

Definition at line 65 of file qgspointcloudattributecombobox.cpp.

◆ setFilters()

void QgsPointCloudAttributeComboBox::setFilters ( QgsPointCloudAttributeProxyModel::Filters filters )

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

See also: filters()

Definition at line 32 of file qgspointcloudattributecombobox.cpp.

◆ setLayer

void QgsPointCloudAttributeComboBox::setLayer ( QgsMapLayer * layer )

slot

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.
