Displaying the ProtoSoupOverview Vertical Divider (2/5/96)

Q: How can I display the vertical divider in a protoSoupOverview?

A: The mechanism for bringing up the vertical divider line was not correctly implemented in protoSoupOverview. You can draw one in a viewDrawScript as follows:

    // setup a cached shape for efficiency    mySoupOverview.cachedLine := nil;    mySoupOverview.viewSetupDoneScript := func()    begin       inherited:?viewSetupDoneScript();           local bounds := :LocalBox();       cachedLine := MakeRect(selectIndent - 2, 0,            selectIndent - 1, bounds.bottom);    end;        mySoupOverview.viewDrawScript := func()    begin       // MUST call inherited script       inherited:?viewDrawScript();           :DrawShape(cachedLine,             {penPattern: vfNone, fillPattern: vfGray});    end;
