The initial developer of this code is Robert Lee.
Requirements:
- Jordan Russell's Toolbar 2000
http://www.jrsoftware.org
Wish list for TB2K:
- tboSameHeight option for toolbar items, used to stretch the item
to the highest possible size.
- It would be nice to have a way to get the TTBItemViewer width and height
even when the Item is not visible (TTBItemViewer.BoundsRect is not valid
when the item is not visible).
As a workaround we should use TTBItemViewer.CalcSize method.
- It would be nice to allow component writers to override
TTBCustomToolbar.CreateWrapper so they can create custom TTBControlItem
items descendants as the dropped control wrappers.
- It would be nice to have access to the TTBPopupMenu Viewer before the
popup is showed to initialize the items, for example to set the focus
on a TTBEditItem.
Development notes:
- All the Windows and Delphi bugs fixes are marked with '[Bugfix]'.
- All the theme changes and adjustments are marked with '[Theme-Change]'.
- All the compatibility changes are marked with '[Backward-Compatibility]'.
- TSpTBXCompoundItemsControl is used as the base class for TB2K items enabled
Controls, it uses the ITBItems interface and streams the items to the DFM.
- When a control is dropped on the toolbar a TTBControlItem is created by
TTBCustomToolbar.CreateWrapper, unfortunately it is created with the
Toolbar.Owner instead of the Form (Owner.Owner for TSpTBXCompoundItemsControl
like the TSpTBXTabSet or TSpTBXStatusBar). The workaround is to handle the
CM_CONTROLCHANGE message in the compound toolbar, stream all the
TTBControlItem.Control to the DFM (the TSpTBXCompoundItemsControl must be
the parent in the DFM), and finally reset the TTBControlItem.Control
parentship to the Toolbar in TSpTBXCompoundItemsControl.Loaded.
