How to Change Font or LineHeight in ProtoListPicker (9/20/96)

Q: How do I set a different font for the items in the protoListPicker?

A: There is a way to change the font in the Newton 2.0 OS, however, we intend to change the mechanism in the future. Eventually, you will be able to set a viewFont slot in the protoListPicker itself and have that work (just like you can set viewLineSpacing slot now). In the meantime, you need a piece of workaround code. Warning: you must set the viewFont of the listPicker AND include this workaround code in the viewSetupDoneScript:

func()
    begin
       if listBase exists and listBase then
          SetValue(listBase, 'viewFont, viewFont) ;

           inherited:?viewSetupDoneScript();
    end;

This will set the viewFont slot of the listBase view to the viewFont of the protoListPicker. You cannot rely on the listbase view always being there, hence the test for its existence.

Note that you can use the same code to modify the lineHeight slot of the listPicker. Just substitute lineHeight for viewFont in the code snippet. The one caveat is that the lineHeight must be at least 13 pixels.
