QgsProcessingParameterField
¶ Bases:
qgis._core.QgsProcessingParameterDefinition
A vector layer or feature source field parameter for processing algorithms.
New in version 3.0: Methods
algorithm
Returns a pointer to the algorithm which owns this parameter. allowMultiple
Returns whether multiple field selections are permitted. asScriptCode
checkValueIsAcceptable
clone
dataType
Returns the acceptable data type for the field. defaultValue
Returns the default value for the parameter. dependsOnOtherParameters
description
Returns the description for the parameter. dynamicLayerParameterName
Returns the name of the parameter for a layer linked to a dynamic parameter, or an empty string if this is not set. dynamicPropertyDefinition
Returns the property definition for dynamic properties. flags
Returns any flags associated with the parameter. fromScriptCode
Creates a new parameter using the definition from a script code. fromVariantMap
isDestination
Returns true if this parameter represents a file or layer destination, e.g. isDynamic
Returns true if the parameter supports is dynamic, and can support data-defined values (i.e. metadata
Returns the parameter’s freeform metadata. name
Returns the name of the parameter. parentLayerParameterName
Returns the name of the parent layer parameter, or an empty string if this is not set. provider
Returns a pointer to the provider for the algorithm which owns this parameter. setAllowMultiple
Sets whether multiple field selections are permitted. setDataType
Sets the acceptable data type
for the field.setDefaultValue
Sets the default value
for the parameter.setDescription
Sets the description
for the parameter.setDynamicLayerParameterName
Sets the name
for the parameter for a layer linked to a dynamic parameter, or an empty string if this is not set.setDynamicPropertyDefinition

for dynamic properties.setFlags
Sets the flags
associated with the parameter.setIsDynamic
Sets whether the parameter is dynamic
, and can support data-defined values (i.e.setMetadata
Sets the parameter’s freeform metadata
.setName
Sets the name
of the parameter.setParentLayerParameterName
Sets the name of the parent layer parameter. toVariantMap
toolTip
Returns a formatted tooltip for use with the parameter, which gives helpful information like parameter description, ID, and extra content like default values (depending on parameter type). type
