Class: QgsIdentifyMenu

class qgis.gui.QgsIdentifyMenu(canvas: QgsMapCanvas)

Bases: PyQt5.QtWidgets.QMenu

QgsIdentifyMenu is a menu to be used to choose within a list of QgsMapTool.IdentifyReults

The QgsIdentifyMenu class builds a menu to be used with identify results (QgsMapToolIdentify). It is customizable and can display attribute actions (QgsAction) as well as map layer actions (see QgsMapLayerAction). It can also embed custom map layer actions, defined for this menu exclusively. If used in a QgsMapToolIdentify, it is accessible via QgsMapToolIdentify.identifyMenu() and can be customized in the map tool sub-class.

setAllowMultipleReturn(self, multipleReturn: bool)

define if the menu executed can return multiple results (e.g. all results or all identified features of a vector layer)

Parameters

multipleReturn (bool) –

setExecWithSingleResult(self, execWithSingleResult: bool)

define if the menu will be shown with a single identify result

Parameters

execWithSingleResult (bool) –

setExpressionContextScope(self, scope: QgsExpressionContextScope)

Sets an expression context scope used to resolve underlying actions.

New in version 3.0.

Parameters

scope (QgsExpressionContextScope) –

setMaxFeatureDisplay(self, maxFeatureDisplay: int)

Defines the maximum number of features displayed in the menu for vector layers (default is 10).

Note

0 is unlimited.

Parameters

maxFeatureDisplay (int) –

setMaxLayerDisplay(self, maxLayerDisplay: int)

Defines the maximum number of layers displayed in the menu (default is 10).

Note

0 is unlimited.

Parameters

maxLayerDisplay (int) –

setResultsIfExternalAction(self, resultsIfExternalAction: bool)

setResultsIfExternalAction if set to False (default) the menu will not return any results if an external action has been triggered

Note

external action can be either custom actions or feature / map layer actions (setShowFeatureActions())

Parameters

resultsIfExternalAction (bool) –

setShowFeatureActions(self, showFeatureActions: bool)

define if attribute actions(1) and map layer actions(2) can be listed and run from the menu

Note

custom actions will be shown in any case if they exist.

Note

  1. attribute actions are defined by the user in the layer properties QgsAction

Note

  1. map layer actions are built-in c++ actions or actions which are defined by a Python plugin QgsMapLayerActionRegistry

Parameters

showFeatureActions (bool) –

showFeatureActions(self) → bool
Return type

bool

styleHighlight(highlight: QgsHighlight)
