KB10294 - How can I persistently select a shape on the monitor?

A shape appearing on the monitor can be selected by simply using:

shp := myshap.MakeEditable;
shp.IsSelected := True;
shp.Invalidate ;


A non standard style for selection can be prepared as:


layer.ParamsList.Add ;
layer.Params.Style := 'selected' ;
layer.Params.Area.OutlineWidth := 1 ;
layer.Params.Area.Color := clBlue ;


Or via an .ini file as:


[TatukGIS Layer 1]
Style=selected
Area.OutlineWidth := 1 ;
Area.Color := clBlue ;


There is a sample showing this functionality in the Samples Set #3 called "Multiselect".
