sec_interp.gui.ui.pages.section_feature_selector module

Feature selector with optional label field for the section line.

class sec_interp.gui.ui.pages.section_feature_selector.SectionFeatureSelector(*args: Any, **kwargs: Any)

Bases: QWidget

Select a 2-vertex section feature and the field used for its label.

The feature combo only lists valid section lines (exactly two vertices, single part). The label field combo offers Auto plus every attribute field of the current layer. The selected field only affects the displayed text; it does not change the feature id or any preview/cache input.

MAX_FEATURES = 500

Select a label field by name; fall back to Auto when missing.
