A widget wrapper for Processing parameter value widgets.
Base class for all map layer types.
Definition: qgsmaplayer.h:73
Contains information about the context in which a processing algorithm is executed.
WidgetType
Types of dialogs which Processing widgets can be created for.
@ Standard
Standard algorithm dialog.
Base class for the definition of processing parameters.
An interface for Processing widget wrapper factories.
Encapsulates a QGIS project, including sets of map layers and their styles, layouts,...
Definition: qgsproject.h:104
#define SIP_FACTORY
Definition: qgis_sip.h:76
Used to store input layer Id and other associated parameters.
