broke everything. If the added item has no chance to calculate it's height, _RecalcItemTops() won't work of course. Whatever this was supposed to fix, there has to be a correct way. * Override BView::SetFont() to update all the items. I remember wanting to implement this, that's why I refactored a _FontChanged() method, but I obviousy never did... * Moved the AttachedToWindow() and FrameMoved() implementations to a more logical position in the file. * Implement B_PAGE_UP/DOWN key presses. Don't know if that's what the BeOS implementation did, will check later. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28671 a95241bf-73f2-0310-859d-f6bbb57e9c96
