Member Enumeration Documentation

◆ FilterType

enum QgsAttributeForm::FilterType

Filter types.

Enumerator
ReplaceFilter	Filter should replace any existing filter.
FilterAnd	Filter should be combined using "AND".
FilterOr	Filter should be combined using "OR".

Definition at line 63 of file qgsattributeform.h.

◆ Mode

enum QgsAttributeForm::Mode

Form modes.

Deprecated:: Use QgsAttributeEditorContext::Mode instead.

Enumerator
SingleEditMode	Single edit mode, for editing a single feature.
AddFeatureMode	Add feature mode, for setting attributes for a new feature. In this mode the dialog will be editable even with an invalid feature and will add a new feature when the form is accepted.
MultiEditMode	Multi edit mode, for editing fields of multiple features at once.
SearchMode	Form values are used for searching/filtering the layer.
