Class: QgsFileFilterGenerator¶

Abstract interface for classes which generate a file filter string.

This interface can be inherited by classes which can generate a file filter string, for use in file open or file save dialogs.

Added in version 3.14.

Note

This is an abstract class, with methods which must be implemented by a subclass.

The following methods must be implemented: createFileFilter()

Class Hierarchy¶

`QgsProcessingDestinationParameter`	Base class for all parameter definitions which represent file or layer destinations, e.g. parameters which are used for the destination for layers output by an algorithm.
`QgsProcessingParameterFeatureSource`	An input feature source (such as vector layers) parameter for processing algorithms.
`QgsProcessingParameterFile`	An input file or folder parameter for processing algorithms.
`QgsProcessingParameterMapLayer`	A map layer parameter for processing algorithms.
`QgsProcessingParameterMeshLayer`	A mesh layer parameter for processing algorithms.
`QgsProcessingParameterMultipleLayers`	A parameter for processing algorithms which accepts multiple map layers.
`QgsProcessingParameterPointCloudLayer`	A point cloud layer parameter for processing algorithms.
`QgsProcessingParameterRasterLayer`	A raster layer parameter for processing algorithms.
`QgsProcessingParameterVectorLayer`	A vector layer (with or without geometry) parameter for processing algorithms.

Abstract Methods

This method needs to be reimplemented in all classes which implement this interface and return a file filter.
