RubberBand select immediately

Hi,
is there a possibility to select/unselect Parts while moving the Rubberband?

I would like to have the Parts selected in the order the user has moved the Rubberband.

CreateCustom DragSelectingTool? But which Methods to override?

I found it! Read the manual.
Sorry for that.

I’m glad that there’s someone who reads the documentation. Sometimes I wonder whether all that effort was wasted.
