allowMidVertexSelection property

bool allowMidVertexSelection

True if a mid-vertex of a polygon or polyline can be interactively selected, false otherwise. Default is true.

By default, mid-vertices (GeometryEditorMidVertex) are displayed and can be helpful in interactive workflows to provide a visual cue that new vertices can be inserted between the existing vertices of polygons and polylines. They may be most helpful for users with less editing experience.

If true, and ReticleInteractionConfiguration.allowVertexCreation is also true, you can position the reticle over a mid-vertex, tap to select it and start the move, then drag the map to reposition the reticle - feedback symbols update to show what change will be made to the GeometryEditor.geometry when you next tap on the map view. Tap a second time to complete the move and drop the new vertex at the reticle position and update the GeometryEditor.geometry.

If false, and you also do not intend to programmatically select any mid-vertices (GeometryEditor.selectMidVertex) then set GeometryEditorStyle.midVertexSymbol to null to prevent the display of unusable mid-vertices.

Whether true or false, a mid-vertex can be selected by GeometryEditor.selectMidVertex.
