Is there a standard way to handle the selection/unselection of points in a custom tool?

I mean something like the EditingTool behaves. When I subclass my custom tool from the EditingTool, the selection behaviour is there, but I don’t want the editing/moving of points in my tool.

If I subclass the BaseEventTool, I know how to find out where clicking/dragging starts and stops, but is there an easy way to find out the affected points to manage the selection myself? Something like CurrentGlyph.getPointsInsideBox((x0, y0), (x1, y1)) perhaps?

you can use fontTools pointInRect
```
from fontTools.misc.arrayTools import pointInRect

for contour in CurrentGlyph():
    for point in contour.points:
        print pointInRect((point.x, point.y), (minx, miny, maxx, maxy))
```
take a look at the PolygonSelectionTool https://github.com/typemytype/RoboFontExamples/blob/master/tools/polygonSelectionTool.py

good luck!
