Clicking the calendar both on and off events and using ctrl+click has no effect.

box supports mousewheel scrolling, but it doesn't work in Calendar because the 
view never gets focus.
After setting focus to the Calendar views, scrolling works as expected.
Not sure what is the cleanest ways to do this, onclick in js, xul or css.

Can be done by adding the property:
   -moz-user-focus      : normal
to calendar.css for .day-view-event-text-class, .day-view-event-text-
class, .week-view-hour-box-class, .week-view-event-class

(sorry, no cvs/diff here..)

Attachment: Patch for classic skin calendar.css

allows focus on week/day-view events and hours

Checked into CVS, the only thing now is that you have to click on the day view
and week view in order to focus it, I can't figure out how to focus the boxes
without having to click on them. 
document.getElementById( "boxtofocus" ).focus() doesn't work.

Maybe "focus" isn't the problem. Most other applications will allow mousewheel
scrolling just by *hovering* over the scrollable area (no click needed, no
visible "focussing" occurs). I don't think that involves "focus" (but maybe I
understand the term "focus" wrong). There is a longstanding :( bug somewhere
(#?) about the mousewheel not always scrolling properly.

Following code seems to work on Windows XP, switching views with the toolbar 
buttons make the view scroll with the mousewheel without clicking. Only thing 
missing is focus on initial view.


/** PUBLIC
*
*   Switch to the day view if it isn't already the current view
*/

CalendarWindow.prototype.switchToDayView = function( )
{
   document.getElementById("day-tree-item-0").focus();

   this.switchToView( this.dayView )
}


/** PUBLIC
*
*   Switch to the week view if it isn't already the current view
*/

CalendarWindow.prototype.switchToWeekView = function( )
{
   document.getElementById("week-tree-hour-0").focus();

   this.switchToView( this.weekView )
}

Checked into CVS, the only thing left is that if you start the calendar in
something other than month view, it doesn't work.

It work for me when setting the focus in the CalendarWindow constructor:
   switch( SelectedIndex )
   {
      case "1":
         this.currentView = this.weekView;
         document.getElementById("week-tree-hour-0").focus();

         break;
      case "2":
         this.currentView = this.dayView;
         document.getElementById("day-tree-item-0").focus();

         break;
