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

Returns the action scope's 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().

See also: setDescription()

Definition at line 72 of file qgsactionscope.cpp.

◆ expressionContextScope()

QgsExpressionContextScope QgsActionScope::expressionContextScope ( ) const

Returns the expression context scope for the action scope.

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.

See also: setExpressionContextScope()

Definition at line 37 of file qgsactionscope.cpp.

◆ id()

QString QgsActionScope::id ( ) const

Returns the unique identifier for this action scope.

See also: setId()

Definition at line 47 of file qgsactionscope.cpp.

◆ isValid()

bool QgsActionScope::isValid ( ) const

Returns true if this scope is valid.

Definition at line 57 of file qgsactionscope.cpp.

◆ operator==()

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

Definition at line 32 of file qgsactionscope.cpp.

◆ setDescription()

void QgsActionScope::setDescription ( const QString & description )

Sets the action scope's 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().

See also: description()

Definition at line 77 of file qgsactionscope.cpp.

◆ setExpressionContextScope()

void QgsActionScope::setExpressionContextScope ( const QgsExpressionContextScope & expressionContextScope )

Sets the expression context scope for the action scope.

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.

See also: expressionContextScope()

Definition at line 42 of file qgsactionscope.cpp.

◆ setId()

void QgsActionScope::setId ( const QString & id )

Sets the unique id for this action scope.

See also: id()

Definition at line 52 of file qgsactionscope.cpp.

◆ setTitle()

void QgsActionScope::setTitle ( const QString & title )

Sets the action scope's title.

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

See also: title()

◆ title()

QString QgsActionScope::title ( ) const

Returns the action scope's title.

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