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().

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.

Definition at line 37 of file qgsactionscope.cpp.

◆ id()

QString QgsActionScope::id ( ) const

A unique identifier for this action scope.

Definition at line 47 of file qgsactionscope.cpp.

◆ isValid()

bool QgsActionScope::isValid ( ) const

Returns if this scope is valid.

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().

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.

Definition at line 42 of file qgsactionscope.cpp.

◆ setId()

void QgsActionScope::setId ( const QString &  id)

A unique identifier for this action scope.

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.

Definition at line 67 of file qgsactionscope.cpp.

◆ title()

QString QgsActionScope::title ( ) const

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

Definition at line 62 of file qgsactionscope.cpp.
