Detailed Description

An action scope defines a "place" for an action to be shown and may add additional expression variables.

Each QgsAction can be available in one or several action scopes.

Examples:

Canvas: Show for canvas tools. Adds @click_x and @click_y in map coordinates.
Feature: Show in feature specific places like the attribute table or feature form.
Field: Show in context menus for individual fields (e.g. attribute table). Adds @field_index, @field_name and @field_value.
Layer: Show in attribute table and work on the layer or selection.

Member Function Documentation

◆ description()

QString QgsActionScope::description ( ) const

The description should be a longer description of where actions in this scope are available.

It is not necessary to list the available expression variables in here, they are extracted automatically from the expressionContextScope().

Since: QGIS 3.0

Definition at line 72 of file qgsactionscope.cpp.

◆ expressionContextScope()

QgsExpressionContextScope QgsActionScope::expressionContextScope ( ) const

An expression scope may offer additional variables for an action scope.

This can be an field_name for the attribute which was clicked or click_x and click_y for actions which are available as map canvas clicks.

Since: QGIS 3.0

Definition at line 37 of file qgsactionscope.cpp.

◆ id()

QString QgsActionScope::id ( ) const

A unique identifier for this action scope.

Since: QGIS 3.0

Definition at line 47 of file qgsactionscope.cpp.

◆ isValid()

bool QgsActionScope::isValid ( ) const

Returns if this scope is valid.

Since: QGIS 3.0

Definition at line 57 of file qgsactionscope.cpp.

◆ operator==()

bool QgsActionScope::operator== ( const QgsActionScope & other ) const

Compares two action scopes.

Definition at line 32 of file qgsactionscope.cpp.

◆ setDescription()

void QgsActionScope::setDescription ( const QString & description )

The description should be a longer description of where actions in this scope are available.

It is not necessary to list the available expression variables in here, they are extracted automatically from the expressionContextScope().

Since: QGIS 3.0

Definition at line 77 of file qgsactionscope.cpp.

◆ setExpressionContextScope()

void QgsActionScope::setExpressionContextScope ( const QgsExpressionContextScope & expressionContextScope )

An expression scope may offer additional variables for an action scope.

This can be an field_name for the attribute which was clicked or click_x and click_y for actions which are available as map canvas clicks.

Since: QGIS 3.0

Definition at line 42 of file qgsactionscope.cpp.

◆ setId()

void QgsActionScope::setId ( const QString & id )

A unique identifier for this action scope.

Since: QGIS 3.0

Definition at line 52 of file qgsactionscope.cpp.

◆ setTitle()

void QgsActionScope::setTitle ( const QString & title )

The title is a human readable and translated string that will be presented to the user in the properties dialog.

Since: QGIS 3.0

Definition at line 67 of file qgsactionscope.cpp.

◆ title()

QString QgsActionScope::title ( ) const
